BOURNS SRF0905-100Y 共模扼流圈产品概述

一、产品定位与核心身份

BOURNS SRF0905-100Y是一款表面贴装(SMD)共模扼流圈,专为抑制电路中的共模电磁干扰(EMI)设计。作为BOURNS旗下成熟的EMI滤波元件,该型号采用双绕组结构,适配多通道信号或电源线路的干扰抑制需求,广泛应用于消费电子、通信、工业控制等领域,是电路EMC整改的常用选型。

二、基础电气参数解析

该型号核心参数覆盖从低频到高频的干扰抑制场景,关键指标清晰:

  • 通道与电感:2通道设计,共模电感值为10μH(测试频率1kHz),可稳定抑制低频段共模噪声;
  • 电流能力:额定直流电流1.6A,满足中小功率电路的电流需求,工作时温度上升可控(符合行业标准);
  • 高频阻抗:300MHz频率下共模阻抗达200Ω,对射频类高频共模干扰具有较强抑制能力;
  • 电压参数:额定工作电压80V(直流/交流有效值),绝缘耐电压500V(测试电压),保障电路绝缘安全;
  • 低损耗:单通道直流电阻(DCR)仅80mΩ,导通损耗小,发热低,适合对功耗敏感的设备。

三、封装与机械结构

SRF0905-100Y采用水平式表面贴装封装,4引脚配置,适配标准PCB板的贴装工艺:

  • 支持回流焊、波峰焊等自动化生产流程,无需额外手工操作;
  • 封装尺寸符合SMD元件的批量生产要求,可直接集成于紧凑电路设计中,节省PCB空间。

四、核心性能优势

  1. 宽频干扰抑制:从1kHz低频电感稳定到300MHz高频高阻抗,覆盖电源纹波、射频噪声等常见共模干扰,无需并联多颗元件即可实现宽频滤波;
  2. 低损耗高效能:80mΩ低DCR大幅降低导通损耗,减少电路发热,提升整体能效,尤其适合便携式电子设备;
  3. 高可靠性:工作温度范围-40℃~+105℃,满足工业级与消费电子的宽温要求;500V耐电压保障绝缘安全,应对瞬态电压波动;
  4. 双路同步滤波:2通道结构可同时对双路信号/电源线路滤波,简化电路设计(无需两路分别配置扼流圈)。

五、典型应用场景

该型号性能适配多类电路的EMI滤波需求:

  • 电源系统:开关电源、LED驱动电源的输入/输出滤波,满足CE、FCC等EMC标准;
  • 通信接口:USB 2.0/3.0、HDMI、以太网接口的信号滤波,提升数据传输稳定性;
  • 工业控制:PLC、伺服驱动器的电源与控制线路滤波,适应工业环境宽温、高可靠要求;
  • 消费电子:笔记本电脑、显示器、机顶盒的EMC整改,解决产品认证中的干扰问题。

六、选型与应用注意事项

  1. 电流余量:实际工作电流需低于1.6A,峰值电流(如开关电源浪涌)建议预留30%以上余量;
  2. 电压匹配:工作电压不超过80V,绝缘测试需在500V以下(符合安全规范);
  3. 频率补充:若干扰频率高于300MHz,需并联陶瓷电容等元件强化滤波;
  4. 贴装布局:水平式封装需注意PCB引脚间距,避免短路;绕组两端建议预留Y电容布局空间,提升滤波效果。

这款共模扼流圈凭借BOURNS的可靠品质、宽频滤波能力与低损耗设计,成为中小功率电路EMI整改的常用元件,适配多类电子设备的量产需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
