GZ1608D221TF 是顺络(Sunlord)品牌的一款0603封装磁珠元件,主要用于电源与信号线的电磁干扰(EMI)抑制与去耦。该器件在100MHz时阻抗为220Ω,阻抗误差±25%,直流电阻(DCR)为300mΩ,额定通过电流为300mA,工作温度范围为-55℃至+125℃,为单通道(单线)器件,适合表面贴装工艺。
计算参考:在额定电流下,电压压降 ≈ I×R = 0.3A×0.3Ω = 0.09V(90mV);功耗 ≈ I²R = 0.3²×0.3 = 0.027W(27mW),在实际设计中应考虑这些损耗及热升。
总结:GZ1608D221TF 为一款适用于一般电源与EMI抑制场景的0603磁珠,提供在100MHz处较高的阻抗值,适合对中高频噪声抑制有要求且电流在300mA以内的便携与消费类电子设计。请在最终设计中结合实际频谱、压降和热预算进行验证。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
