CM453232-471KL(BOURNS,1812 封装)为磁胶屏蔽功率电感,标称电感值 470 µH,公差 ±10%。器件针对对电磁兼容和体积有较高要求的低电流电源与滤波场景设计,采用屏蔽结构以降低外漏磁场对周围敏感电路的干扰。
1812 封装兼顾体积与功率容量,具体推荐的焊盘尺寸、回流曲线、环境规范及电气特性曲线(频率响应、温度系数、饱和电流特性等)请以 BOURNS 官方数据手册为准,样品评估阶段建议获取实物样件进行温升及滤波性能测试。
总结:CM453232-471KL 为适用于低电流、强调 EMI/滤波效果的屏蔽功率电感,470 µH 的较大电感值使其在中低频滤波上效果明显,但 26 Ω 的 DCR 和 62 mA 的额定电流限制了其在高功率应用中的使用,应根据实际电流、效率与热管理需求谨慎选型。

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.
