BOURNS推出的SRF0504-191Y是一款专为电磁干扰(EMI)抑制设计的双路共模滤波器,凭借均衡的电气性能、宽温可靠性及紧凑封装,适用于工业、通信、车载等多场景的干扰抑制需求,是电路EMC设计的实用选型。
该滤波器属于共模电感类EMI器件,核心作用是精准抑制线路中的共模干扰:
当电流以共模形式(如电源线路中流向负载与返回电源的电流同相)传输时,绕组产生的磁场叠加,显著提升电感量以阻碍共模电流;而差模电流(信号/电源的正常传输形式)通过时,绕组磁场相互抵消,不影响信号完整性。双路设计可同时处理两路独立线路的共模干扰,简化电路布局,减少额外器件使用。
该产品的参数经过优化,兼顾干扰抑制能力与功率传输效率:
该滤波器采用水平式4引脚PCB封装,结构设计具备以下优势:
该产品的环境适应性满足严苛场景需求:
总结而言,BOURNS SRF0504-191Y共模滤波器凭借双路设计、中高频干扰抑制能力、宽温可靠性及低损耗特性,成为工业、通信、车载及消费电子领域EMI抑制的实用选择,适配多种中等功率与宽温场景的电路需求。

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.
