YSPI1040-3R3M一体成型功率电感产品概述

一、产品基本属性与命名解析

YSPI1040-3R3M是益嘉源(YJYCOIN) 推出的一款一体成型贴片功率电感,专为中大功率电源电路设计。其命名规则清晰对应核心特性:

  • YSPI:益嘉源功率电感系列标识;
  • 1040:封装尺寸的行业习惯编号(对应实际物理尺寸11.5×10×4mm);
  • 3R3:电感值标称3.3μH(“R”代表小数点);
  • M:电感精度等级,对应±20%公差范围。

该产品采用表面贴装(SMD)工艺,可直接兼容自动化贴片生产线,无需额外焊接辅助,适配各类紧凑PCB设计。

二、核心电气性能参数详解

作为功率电感,电气参数直接决定电路功能表现,YSPI1040-3R3M的关键参数如下:

  1. 电感值与精度:标称3.3μH,精度±20%。该值处于中功率电感典型区间,可有效满足DC-DC转换、滤波等场景的储能需求;±20%公差覆盖大部分工业、消费电子的设计余量,无需额外高精度筛选。
  2. 额定电流(Irms):11A。此为电感持续工作时不超允许温升(通常≤40℃)的最大电流,可稳定承载中大功率负载(如CPU、电机驱动等),避免磁芯饱和或性能衰减。
  3. 直流电阻(DCR):10.8mΩ(毫欧级)。低DCR是核心优势——直流电阻越小,线圈铜损越低,电路效率越高,同时减少发热(10A负载下损耗仅约1.08W),提升长期可靠性。

三、机械封装与物理特性

YSPI1040-3R3M的机械设计兼顾紧凑性与可靠性:

  • 封装尺寸:实际尺寸11.5mm(长)×10mm(宽)×4mm(高),属于小体积功率电感,可节省PCB空间,适配轻薄化设备(如笔记本、车载中控)。
  • 一体成型结构:磁芯与线圈一体化压制,相比传统绕线电感,优势显著:① 无磁芯间隙,降低磁损与EMI干扰;② 结构强度高,抗振动(10G以上)、抗冲击,适配工业、车载恶劣环境;③ 批量一致性好,性能波动小。
  • 磁芯材料:采用合金粉芯(或铁粉芯),兼顾磁导率与饱和电流,平衡电感值与电流承载能力。

四、典型应用场景

基于电气与机械特性,该产品广泛适用于:

  1. 电源转换电路:DC-DC降压/升压模块(服务器电源、笔记本适配器、LED驱动),低DCR提升转换效率,11A电流满足大功率负载。
  2. 工业控制设备:PLC、电机驱动器、变频器,一体成型结构抗振动,适配工业现场机械应力。
  3. 车载电子:车载充电器、中控系统、LED车灯驱动,满足-40℃~85℃宽温与振动要求。
  4. 通信设备:基站电源、路由器、交换机,低EMI特性减少射频干扰。
  5. 消费电子:大功率移动电源、智能电视电源,小体积适配轻薄化设计。

五、产品核心优势

对比同规格传统绕线电感,YSPI1040-3R3M的差异化优势:

  1. 低损耗高效率:10.8mΩ DCR使电源效率提升2%~3%,减少散热需求。
  2. 高可靠性:一体成型结构抗振动冲击,MTBF远超传统绕线电感。
  3. 宽电流适配:11A额定电流覆盖中大功率场景,无需并联多颗电感,简化电路。
  4. 紧凑空间利用:小尺寸适配高密度PCB,助力设备小型化。
  5. 稳定性能:-40℃~125℃范围内电感值变化率≤±10%,温度特性优异。

YSPI1040-3R3M凭借低损耗、高可靠、紧凑封装等特性,成为中大功率电源电路的优选电感,适用于工业、车载、消费电子等多领域设计需求。

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
