BOURNS SRN6045-101M 功率电感产品概述

一、产品定位与核心价值

BOURNS SRN6045-101M是一款专为小型化低功耗电源电路设计的SMD贴片功率电感,核心定位是平衡“小封装”与“实用电性能”,适配消费电子、物联网、小型工业控制等领域的高密度集成需求。其核心价值体现在:6×6mm紧凑封装下实现100uH电感值与700mA额定电流,低直流电阻(DCR)提升电源效率,同时依托BOURNS品牌保障可靠性,是批量量产场景的高性价比选择。

二、关键电性能参数深度解析

1. 电感值与精度

电感值为100uH(标识101M,其中“10”为有效数字,“1”为10的幂次,“M”代表±20%精度),该参数匹配大多数DC-DC转换、滤波电路的电感需求——既不会因电感值过大导致响应速度慢,也不会因过小无法满足储能要求,可覆盖100kHz~2MHz的常见开关频率范围。

2. 电流能力(额定电流vs饱和电流)

  • 额定电流700mA:设备连续工作时允许通过的最大电流,此时电感值变化≤10%,升温可控(通常≤40℃),符合电源电路长期稳定运行的要求;
  • 饱和电流800mA:电感磁芯饱和时的临界电流(电感值下降至额定值的70%左右),若电路峰值电流超过此值,会导致电感储能能力骤降、输出电压波动,因此设计时需确保峰值电流不超过800mA。

3. 直流电阻(DCR)

DCR为494mΩ,低阻值直接降低连续工作时的功耗(功耗=I²×R,700mA下功耗约0.24W),减少电源转换损耗,尤其适合电池供电的便携式设备(如蓝牙耳机、智能手环)延长续航。

三、封装与物理特性

1. 封装规格

采用6×6×4.5mm SMD封装(“6045”标识对应尺寸:长6mm、宽6mm、高4.5mm),引脚间距符合标准贴装要求,可兼容0402、0603等小型贴片元件的PCB布局,适配高密度集成设计(如智能手机主板、物联网终端模块)。

2. 贴装兼容性

支持回流焊、波峰焊工艺,引脚设计符合IPC-A-610标准,自动贴装效率高;无铅(RoHS compliant)、无卤素设计,满足欧盟及国内环保要求,可用于出口产品。

3. 环境适应性

磁芯采用合金材料(低损耗、抗饱和),耐温范围为**-40℃125℃**,可覆盖工业级(-4085℃)、汽车级(部分低功耗场景)的温度需求,抗振动(10G@20~2000Hz)、抗冲击(50G)性能符合行业标准,适合户外或工业现场应用。

四、典型应用场景

1. 便携式消费电子

  • 手机/平板:DC-DC降压电路(5V→3.3V/1.8V)的储能电感,满足主控芯片、摄像头模块的供电需求;
  • 蓝牙耳机/智能手表:低功耗电源管理,100uH电感匹配500kHz开关频率,700mA额定电流覆盖最大工作电流(200~500mA),小封装节省内部空间。

2. 物联网终端

  • 智能家居传感器(温湿度、人体感应):电源模块的滤波电感,稳定3.7V锂电池输出;
  • 工业无线节点:低功耗MCU供电,耐宽温特性适配户外环境(-20~60℃)。

3. 小型工业控制

  • PLC I/O模块:数字量输出电路的滤波电感,减少电磁干扰;
  • 小型伺服电机驱动:辅助电源的储能元件,支持100mA~700mA的负载电流。

4. 低功耗汽车电子

  • 胎压监测传感器(TPMS):电池供电的电源转换,耐-40~85℃车载温度范围;
  • 车载USB充电口:辅助滤波,提升充电稳定性。

五、品牌与质量保障

BOURNS作为全球知名电子元器件制造商,SRN6045-101M经过严格的可靠性测试:

  • 温度循环(-40~125℃,1000次)后电感值变化≤5%;
  • 湿度测试(85℃/85%RH,1000h)后DCR变化≤10%;
  • 批量生产一致性好(参数偏差控制在±10%内),降低客户筛选成本。

综上,BOURNS SRN6045-101M是一款“小而实用”的功率电感,精准匹配低功耗、小型化电源电路的需求,兼具可靠性与性价比,是消费电子、物联网等领域的优选方案。

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.
