YI201209U201-4R0T是益嘉源(YJYCOIN)推出的一款0805封装高频电磁干扰抑制磁珠,专为大电流场景下的电源/信号线路噪声过滤设计,平衡了高频干扰抑制能力与低直流损耗特性,适用于多种工业、消费及通信类电子设备。
该磁珠的核心设计围绕「高频噪声抑制+大电流承载+低损耗」三大需求展开:
在100MHz频段下阻抗为200Ω,误差范围±25%(即150Ω~250Ω)。该参数是磁珠抑制EMI的核心指标:100MHz是电子设备中常见的干扰频段(如开关电源纹波、射频电路杂散),200Ω的阻抗可有效衰减该频段的噪声信号,提升电路抗干扰能力。
该磁珠因兼顾大电流与高频抑制,主要应用于以下场景:
益嘉源(YJYCOIN)是国内专注于被动元器件研发生产的品牌,该磁珠通过以下可靠性测试:
该产品通过平衡高频抑制与大电流承载能力,成为中小功率电子设备EMI滤波的实用选择,适配多种复杂应用场景。

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.
