YI201209A401-3R0T是YJYCOIN(益嘉源)推出的0805封装高频铁氧体磁珠,针对中高频噪声抑制场景优化设计,在小体积(2012公制尺寸)下平衡了阻抗性能、电流承载能力与宽温稳定性,适合高密度电路的噪声滤波需求。
该磁珠属于工业级宽温型高频抑制元件,核心价值体现在三个维度:
磁珠的核心作用是高频噪声抑制,该产品在100MHz频段的阻抗为400Ω(±25%误差),属于行业常见的“有效抑制点”——100MHz是开关电源(如DC-DC)、蓝牙/WiFi等射频电路的典型噪声频段,此阻抗值可有效衰减该频段的干扰信号,提升电路EMC性能。
低DCR(40mΩ)是大电流应用的关键:
-55℃+125℃的宽温范围,说明磁珠的铁氧体材料在极端温度下性能稳定(无显著阻抗漂移或磁饱和风险),可覆盖工业控制(-40℃+85℃)、车载子系统(-40℃~+105℃)等场景的温度需求。
该产品采用0805贴片封装(公制2012),具备以下优势:
结合参数特性,该磁珠主要应用于以下场景:
该产品以“小封装+大电流+宽温高频抑制”为核心竞争力,适配中高端电子设备的噪声滤波需求,是高密度电路设计中性价比突出的选择。

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.
