BOURNS SRN8040-220M 功率电感器产品概述

一、产品基本定位与核心优势

SRN8040-220M是BOURNS推出的半屏蔽表面贴装(SMD)功率电感器,专为中小功率电源电路的储能、滤波及EMI抑制设计。其核心优势聚焦于「平衡性能与成本」,具体体现为:

  1. EMI与体积的平衡:半屏蔽结构既降低对外电磁辐射,又避免全屏蔽电感的体积冗余,适配空间紧凑的高密度PCB设计;
  2. 电流效率的优化:低直流电阻(DCR)减少热损耗,额定电流与饱和电流均为2.2A,保证连续工作时的性能稳定性;
  3. 场景适配的灵活性:参数覆盖消费类、工业控制等多领域,是中小功率电源设计的高性价比选择。

二、关键电气参数详解

该电感的核心电气参数直接决定应用适配性,具体如下:

  • 电感值与精度:22μH±20%,电感量稳定,满足一般电源电路的储能需求,精度范围适配大多数工业/消费类场景的设计余量;
  • 额定电流(Irms):2.2A(有效值),连续工作电流不超过此值时,电感性能无明显衰减,可长期稳定运行;
  • 饱和电流(Isat):2.2A,当电流达到此值时,电感值下降≤30%(行业常规标准),此参数与额定电流一致,说明设计上对饱和降额的控制较好,避免突发电流导致性能波动;
  • 直流电阻(DCR):100mΩ,直流损耗低,可有效降低电源电路的热耗散,提升整体效率;
  • 频率适配:适配100kHz~1MHz的主流开关频率(行业常规功率电感特性),兼容各类DC-DC转换器的工作场景。

三、物理特性与封装规格

该电感采用表面贴装工艺,物理特性适配自动化生产与空间紧凑设计:

  • 封装尺寸:7.9mm(长)×8.2mm(宽),为常规SMD功率电感的紧凑尺寸,可直接集成于高密度PCB板;
  • 封装类型:半屏蔽结构,通过局部磁屏蔽减少电磁干扰,同时降低制造成本与体积;
  • 焊接兼容性:符合RoHS标准,支持回流焊、波峰焊等主流SMD焊接工艺,适合规模化生产;
  • 温度范围:常规工作温度为-40℃~+85℃(行业适配),可满足户外/工业环境的温度需求。

四、典型应用场景

SRN8040-220M的参数特性使其适配多领域的中小功率电源设计:

  1. 消费类电子:智能手机、平板电脑的电源管理模块(PMIC)滤波,以及无线充电设备的储能电感;
  2. 工业控制:小型PLC、传感器节点、电机驱动的DC-DC转换电路,用于电压转换与纹波抑制;
  3. 汽车电子:低功率车载辅助系统(如USB充电端口、仪表盘背光)的滤波电感,适配车载环境可靠性要求;
  4. 通信设备:小型路由器、IoT网关的电源滤波电路,减少电磁干扰对信号传输的影响。

五、品牌与可靠性背书

BOURNS作为全球知名被动元件厂商,产品可靠性与一致性有充分保障:

  • 品牌实力:拥有数十年研发生产经验,产品广泛应用于航空航天、汽车、工业等高端领域;
  • 质量认证:符合ISO 9001质量管理体系,部分型号通过AEC-Q200(汽车级)认证(适配场景);
  • 批量一致性:标准化生产工艺保证参数一致性,适合大规模生产的稳定需求。

该产品以「高性价比+稳定性能」成为中小功率电源设计的优选电感,可满足多数场景的实际需求。

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
