SRF2012A-801Y是BOURNS公司推出的一款小型化表面贴装共模扼流器(Common Mode Choke,简称CMC),专为高频电磁干扰(EMI)抑制设计,兼具小体积、宽温适应性与高噪声抑制能力,适用于高密度PCB布局的电子设备。
作为一款共模扼流器,SRF2012A-801Y的核心作用是抑制电路中的共模噪声(即两条传输线中相位相同、方向相同的干扰信号),同时对差模信号(传输线中相位相反、方向相反的有效信号)保持低损耗传输。该产品针对100MHz频段的共模噪声优化,是解决高频EMI问题的针对性器件,可帮助设备快速通过电磁兼容(EMC)认证。
该产品的电气参数围绕“噪声抑制能力”与“可靠性”两大核心设计,关键参数及意义如下:
该产品具备宽温工作能力,工作温度范围为-55℃~+125℃,可适应以下复杂环境:
结合参数特性,SRF2012A-801Y的典型应用包括:
综上,SRF2012A-801Y是一款平衡“小体积、高频EMI抑制、宽温适应”的实用型共模扼流器,可有效解决高密度电子设备中的共模噪声问题,是电子工程师进行EMI设计的理想选择。

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.
