BLM15GG221SN1D 是村田(muRata)生产的一款表面贴装磁珠(ferrite bead),封装尺寸为 0402,单通道设计,用于电流回路和信号线的高频电磁干扰(EMI)抑制。该型号在 100MHz 时标称阻抗为 220Ω,直流电阻(DCR)约为 700mΩ,额定直流电流 300mA,阻值公差 ±25%。体积小、插入损耗高,适合对 EMI 抑制要求较高且空间受限的便携式和消费类电子产品。
在选型时应综合考虑阻抗频谱、DC 电流需求、允许压降及工作频段。若系统工作频段高于 100MHz,可参考厂商提供的频率响应曲线选择在目标频段阻抗更高的型号;若电流需求大于 300mA,则需选用额定电流更高的磁珠或使用并联/更大封装方案。
总结:BLM15GG221SN1D 以其 0402 小封装、220Ω@100MHz 的高频阻抗和较低的 DCR,适合对 EMI 抑制有较高要求且空间受限的低功耗电子产品。选型时应结合实际工作频段与电流需求,参考村田提供的详细频率响应与可靠性资料以获得最佳性能。

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.
