BOURNS SRR0604-100ML 功率电感产品概述

一、产品核心参数总览

BOURNS SRR0604-100ML是一款针对中小功率电源场景优化的贴片式功率电感,核心参数明确且适配主流应用需求:

  • 电感值:10μH,精度±20%(功率电感常用精度等级,满足大多数电源电路容差要求);
  • 电流规格:额定电流(Irms)1.3A(连续工作电流),饱和电流(Isat)1.8A(电感值下降30%时的峰值电流);
  • 直流电阻(DCR):120mΩ(典型值,低损耗设计关键指标);
  • 封装尺寸:6.5mm×6.5mm SMD贴片封装(小型化设计,适配高密度PCB);
  • 品牌:BOURNS(伯恩斯,全球知名被动元器件制造商)。

型号命名逻辑:“0604”对应封装尺寸规格,“100M”表示电感值10μH(M为μH量级标识),后缀“L”关联低DCR设计特性。

二、关键特性与应用优势

1. 电流性能适配主流场景

  • 额定电流1.3A覆盖了便携式设备、小型工业电路的核心供电需求(如手机PMIC、微型MCU供电);
  • 饱和电流1.8A提供约38%的电流裕量,可有效应对电路瞬态过流(如负载突然启动)或电压波动,避免电感进入饱和区导致电感值骤降(饱和后电感性能失效风险)。

2. 低DCR提升能效与散热

120mΩ的直流电阻显著降低铜损(功耗公式:(P=I^2×R)),当工作电流为1A时,仅产生约0.12W功耗,可减少电源模块发热、延长电池续航(针对便携设备),适配对效率敏感的DC-DC转换电路。

3. 小封装适配轻薄化设计

6.5mm×6.5mm的贴片封装体积紧凑,可直接集成到手机、智能手表、机顶盒等设备的高密度PCB中,满足当前电子设备“小型化、轻量化”的设计趋势。

4. 宽温可靠性(行业默认特性)

BOURNS同类电感通常支持-40℃至+125℃的工作温度范围,可适应工业环境(如低温车间)或低功率车载场景(如行车记录仪电源)的高低温波动。

三、典型应用场景

SRR0604-100ML的参数特性使其精准匹配以下场景:

  1. 便携式电子设备:手机、智能手表、蓝牙耳机的电源管理模块(PMIC),负责DC-DC降压/升压转换,提供稳定的1A级电流输出;
  2. 消费类电子:机顶盒、路由器、智能音箱的主电源电路,支撑MCU、WiFi模块、音频芯片等负载的供电;
  3. 小型工业设备:微型PLC、传感器节点、工业遥控器的辅助电源,满足低功率、小体积的设计需求;
  4. 低功率车载电子:车载充电器、行车记录仪的电源模块,适配紧凑的车载空间与宽温度环境(需确认具体车载级认证,BOURNS产品通常支持基础级应用)。

四、选型与使用注意事项

  1. 电流裕量设计:电路长期工作电流需低于1.3A,瞬态峰值电流需控制在1.8A以内;若需更高电流裕量,需选择同系列更大电感值或电流规格的型号;
  2. 频率匹配:功率电感的电感值与开关频率成反比,SRR0604-100ML适合1MHz以下的开关频率(如500kHz左右的DC-DC电路),高频应用需切换至更小电感值的型号;
  3. 焊接工艺:贴片封装需遵循BOURNS推荐的回流焊温度曲线(如峰值温度240℃左右),避免温度过高导致磁芯开裂或焊接不良;
  4. 环保合规:产品符合RoHS、REACH等环保标准,可满足出口或绿色产品设计需求,无需额外环保整改。

五、品牌可靠性说明

BOURNS作为全球被动元器件领域的头部品牌,其电感产品经过严格的可靠性测试(振动、冲击、温度循环、湿度老化等),批量一致性达行业领先水平,可支持消费级、工业级产品的稳定量产,降低客户的售后风险与研发成本。

综上,SRR0604-100ML是一款“小体积、低损耗、高可靠性”的功率电感,精准适配中小功率电源的核心需求,是便携电子、消费类电子等领域的高性价比选型。

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
