FDCW2012-2-901TF是长江微电(cjiang)推出的高密度小体积共模滤波器,针对高速信号链路的共模干扰抑制设计,核心解决「空间紧凑场景下的EMI抑制与信号完整性平衡」问题。其定位覆盖消费电子、工业控制、智能穿戴等多领域,核心价值体现在:0805封装下实现高共模阻抗(900Ω@100MHz),同时兼顾低损耗、宽温可靠性,满足量产一致性与场景适配性。
共模滤波器的性能核心是目标频段的共模阻抗——该产品在100MHz频段(WiFi 2.4G邻频、蓝牙干扰等常见噪声频段)阻抗达900Ω,可有效衰减共模噪声;同时对差模信号损耗极小(因磁芯对差模信号呈低阻抗),不影响USB、HDMI等高速数据传输质量。
该产品采用0805英寸(2012公制)贴片封装,体积仅2.0mm×1.2mm,适配高密度PCB布局(如智能手机主板、智能手表模块)。长江微电采用自主研发的低损耗铁氧体磁芯与精密绕制工艺,确保每批次产品的阻抗一致性偏差≤±10%,满足量产稳定性要求。
智能手机/平板的USB Type-C、HDMI、MIPI等链路,抑制WiFi 2.4G/5G、蓝牙与数据传输的相互干扰,避免EMI测试超标。
PLC、传感器节点的模拟/数字信号线路,过滤电网噪声、电机电磁干扰等共模噪声,提升工业设备信号稳定性。
智能手表、TWS耳机的无线充电、蓝牙信号链路,兼顾小体积与EMI抑制,满足便携设备的空间限制。
车载显示屏、倒车雷达的信号线路,适应-40℃~+85℃的车载环境温度,减少车载电磁环境对信号的干扰。
FDCW2012-2-901TF凭借小体积、高阻抗、宽温等优势,成为高速信号链路EMI抑制的高性价比选择,广泛适配多领域的紧凑空间与干扰抑制需求。

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.
