Introduction: OEM EMI power line filter planning for MRI shielded room projects starts before the RFQ, when the power entrance, load schedule, freight plan, and shielding accessory list are still flexible.
A new MRI shielded room project rarely starts with a single filter on a bench. It starts with a power entrance, a load schedule, a freight plan, and a set of shielding accessories that must fit together. Early OEM planning keeps those decisions aligned. The Haozhuo HZ-2X16A provides a concrete starting point: a 250VAC 16A MRI RF cage filter with dual-stage filtering, through-hole inline mounting, <=0.2 A leakage current, 1000 VDC withstand, and <1 V voltage drop. The sooner these details enter the RFQ, the fewer commercial surprises the project faces later.
The power line filter is part of the shielded envelope, not an afterthought. If the enclosure is drawn first and the filter is chosen later, the project can face a chain reaction: a different mounting footprint, a longer cable route, a revised penetration flange, or a service clearance that no longer works. For a new-build MRI room, electrical and mechanical decisions sit together. When an OEM team talks with an MRI RF filter manufacturer, the specification should already be tied to the enclosure drawing. The HZ-2X16A’s 16A rating, 250VAC working voltage, and dual-stage design set the starting point, while its <=0.2 A leakage current and 1000 VDC withstand address safety expectations in a medical environment. Insertion loss also belongs in the first design conversation: the filter’s >=100 dB suppression across 14 kHz to 40 GHz is a key design factor for conducted noise on power conductors. The mounting envelope determines whether the rest of the room remains buildable. A through-hole inline filter must sit at the power entrance, with enough space for termination, grounding, and future access. The HZ-2X16A is a substantial metal-housed unit, about 20 kg per carton, so wall structure, support method, and lifting plan should be considered before it arrives. If the project load study points to 30A, treat it as a separate specification step and confirm it with engineering early. Physical dimensions and final drawings should also be confirmed during the RFQ. Setting these details early keeps the mechanical package, electrical schedule, and site access plan aligned.
Commercial terms matter as much as the electrical rating when an enclosure builder is buying for a project. A filter that meets the drawing but arrives late, damaged, or in packaging that cannot be handled on site creates the same delay as a wrong specification. The HZ-2X16A has an MOQ of at least 1 piece, which gives OEM teams room to order a sample, a first article, or a small project batch. For larger projects, quantity drives carton count, pallet planning, freight cost, and site receiving labor. The $80 reference price is a starting point; project pricing should come through a formal quote that reflects quantity, configuration, packaging, and shipping terms. An EMI power line filter supplier should quote the full commercial package, not only the unit price.
Each HZ-2X16A is packed one piece per carton at about 20 kg gross weight. That is manageable for a sample, but a multi-unit MRI project turns packaging into a logistics decision. The carton must protect the metal housing and terminals during ocean transit and inland trucking. The buyer should decide whether standard cartons are enough or whether palletization, edge protection, moisture barrier, and carton marking are needed for the site. Quantity also affects receiving: a few cartons can be moved with a pallet jack, while a full project order may need a loading dock, forklift, or crane. Good packaging planning reduces the chance of terminal damage, missing accessories, and extra handling time at the hospital or lab.
Shanghai port shipping is a confirmed supply point for the HZ-2X16A, and the freight handoff should be written into the order before release. Incoterms rules define who books the main carriage, arranges insurance, where risk transfers, and who handles export and import clearance. For an MRI shielded room project, the enclosure builder or OEM procurement team should agree on the named place and the party responsible for inland delivery to the site. The receiving plan matters too: the site may need a delivery window, lifting equipment, dry storage, and someone who can inspect cartons against the packing list. Final lead time and stock position is worth checking at order release so the freight plan matches the construction schedule.
A turnkey RF shielded enclosure project succeeds when the penetrations are planned as one system. The power line filter is one penetration, but shielding doors, honeycomb vents, copper foil, gaskets, and other feedthrough items are part of the same envelope. If each item is sourced separately, the installation crew can find that the filter is ready but the vent frame is not, or the door schedule has moved ahead of the power entrance work. Haozhuo EMI Solutions can discuss OEM customization support and shielding accessory coordination with project teams, so filter supply can be aligned with the other RF components rather than treated as a standalone purchase. Practical coordination starts with an interface list. The project team should share the power entrance drawing, expected filter quantity, mounting method, accessory list, and installation sequence. That helps confirm whether the HZ-2X16A will be installed before or after the shielding door and honeycomb vent frames, and whether the site needs special lifting or sealing materials. OEM documentation should also match the project handover package: product data, packing list, warranty terms, and any agreed labels or instructions. The HZ-2X16A carries a 2-year guarantee; warranty service terms and documentation details should be written into the order contract. When these items move together, the enclosure builder avoids rework at the most expensive stage: final commissioning.
OEM MRI shielded room projects reward early decisions. Set the power line filter specification before the enclosure drawing is frozen, because load, leakage current, insertion loss, mounting envelope, and service access all interact. Plan MOQ, packaging, and Shanghai port freight handoff as part of the commercial package, not as a last-minute logistics task. Then coordinate the filter with shielding doors, honeycomb vents, and the rest of the penetration schedule so the turnkey installation stays on one timeline. For a new-build project, send the electrical rating, quantity, packaging needs, shipping terms, accessory list, and documentation requirements in the RFQ. That gives the supplier enough information to quote the HZ-2X16A configuration or a custom OEM version properly.
A：Include the project type, working voltage, current rating, insertion loss and leakage current targets, mounting method, quantity, packaging needs, shipping terms, site receiving constraints, accessory list, and documentation requirements. For the HZ-2X16A, state whether 250VAC 16A fits the load and whether a 30A version needs engineering review. Also ask for the final outline drawing, packing details, warranty terms, and a project quote based on Shanghai port shipping.
A：MOQ of at least 1 piece makes it practical to order a sample, first article, or small project batch before committing to a larger release. Packaging affects freight and site handling because each HZ-2X16A carton weighs about 20 kg. For multiple units, agree on palletization, carton strength, terminal protection, labeling, and whether the site can receive and store the shipment safely. These choices change freight cost, handling time, and damage risk.
A：Coordination can be discussed as part of the turnkey enclosure package. Share the power entrance drawing, accessory list, installation sequence, and required documentation so filter supply can be aligned with shielding doors, honeycomb vents, gaskets, and other RF components. Final stock, lead time, and accessory availability is worth checking for the specific project before order release.
