FDCW2012-2-300TF是长江微电(cjiang) 推出的0805封装共模滤波器,专为电子设备的电磁干扰(EMI)抑制设计,兼具双通道滤波、低损耗传输与宽温适配特性,适配便携电子、工业控制、物联网等多领域的小型化滤波需求。
该产品属于双通道共模滤波器,核心作用是抑制信号/电源线路中的共模噪声(即两条线路上相位相同、幅值相等的干扰信号),同时保持差模信号(有效传输信号)的低损耗传输。其定位为小型化、中等电流容量的EMI抑制器件,平衡了滤波性能、体积与成本,适合对PCB空间敏感、电流需求适中的设备。
共模阻抗为30Ω@100MHz,这是衡量滤波性能的关键指标:100MHz是电子设备中EMI干扰的高发频段(如射频信号串扰、开关电源高频噪声),30Ω的阻抗可有效衰减该频段内的共模干扰,减少干扰对敏感电路(如传感器、射频模块)的影响。
工作温度范围为**-40℃~+85℃**,覆盖工业级与消费电子的常见温差场景,可稳定工作于户外、车载辅助电路等环境。
采用0805封装(公制2012封装,尺寸2.0mm×1.2mm),属于小型化表面贴装(SMD)封装,具备以下优势:
该产品的参数特性使其适配以下场景:
长江微电作为国内知名电子元器件厂商,产品一致性好、供货稳定;FDCW2012-2-300TF在同规格产品中,平衡了滤波性能、电流容量与成本,是替代进口器件的高性价比选择,适合中小批量及大规模生产需求。
综上,FDCW2012-2-300TF凭借双通道滤波、100MHz频段有效抑制、低损耗与宽温特性,成为电子设备EMI抑制的实用选型,适配多领域的小型化滤波需求。

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.
