BWCU00201212900M02是奇力新(Chilisin)推出的小型化低电流共模滤波器,主打中高频(100MHz附近)共模干扰抑制,兼顾宽温适应性与高可靠性。其核心定位是为消费电子、汽车电子、工业控制等领域的小功率电路提供紧凑的EMI(电磁干扰)解决方案,解决信号/电源线路中的共模噪声问题,满足设备电磁兼容性(EMC)要求。
该产品的核心滤波指标为90Ω共模阻抗@100MHz——共模阻抗越高,对该频段内的共模噪声衰减效果越显著。90Ω的阻抗值在0805封装小型滤波器中属于较高水平,能有效降低电路对外电磁辐射,同时减少外部干扰侵入,适配100MHz左右的干扰场景(如WiFi、蓝牙通信频段)。
350mΩ低DCR是核心优势:直流电阻越低,电路功率损耗越小,尤其适合电池供电的便携设备(如智能穿戴),同时减少自身发热,提升长期可靠性。
工作温度范围**-40℃+105℃**,覆盖工业级(-40+85℃)与部分汽车级(-40~+125℃)温区要求,可在极端环境(低温户外、高温车载)下稳定工作,无需额外降额。
采用0805贴片封装(英制0.08″×0.05″,公制2.0mm×1.2mm),适配常规自动化贴装设备,能有效节省PCB布局空间,适合高密度电路设计(如智能手机主板)。
标注为水平式4 PC板(推测为多层PCB或薄膜绕线结构):
除耐电压125V外,产品经过温度循环、振动测试等可靠性验证,符合RoHS环保要求,量产稳定性达标。
实际工作电流≤330mA(建议≤300mA留裕量),工作电压≤50V,避免过流过压损坏。
若目标干扰频段为100MHz左右,该产品发挥最佳效果;若干扰频段偏离,需结合频谱分析选择对应阻抗滤波器。
0805封装需按常规贴片工艺操作,回流焊峰值温度≤260℃(奇力新推荐值),避免高温损坏。
滤波器尽量靠近干扰源/负载端,输入输出端避免交叉走线,接地端可靠连接以提升滤波效果。
该产品通过紧凑封装、低功耗设计与宽温适应性,成为小功率电路EMI抑制的高性价比选择。

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.
