YSPI0740-100M 功率电感产品概述

一、产品定位与核心特性

YSPI0740-100M是益嘉源(YJYCOIN)推出的一体成型功率电感,专为中小功率电源电路设计,核心聚焦「高电流承载、低损耗、高可靠性」三大实用特性。作为SMD表面贴装电感,其紧凑尺寸适配自动化生产,一体成型结构兼顾电磁兼容性与机械稳定性,可满足消费电子、通信设备等多场景的滤波与储能需求,是性价比突出的电源配套元件。

二、基础参数详解

该电感的核心参数明确且针对性强,直接对应实际应用性能:

  • 电感值:10μH(微亨),精度±20%——满足一般电源电路的储能/滤波核心需求,精度范围适配多数功率应用场景(无需超高精度的电源设计);
  • 额定电流:4.5A(安培)——指电感正常工作时,温升不超过允许范围的最大持续电流,可支撑中等功率的电源输出(如手机快充、小型路由器电源);
  • 直流电阻(DCR):51.5mΩ(毫欧)——低DCR是其核心优势,直接降低电流通过时的功率损耗,提升电源效率(减少发热);
  • 封装尺寸:SMD封装,具体为7.3mm×6.6mm×4mm——紧凑体积适合高密度电路板布局,不占用过多空间,适配便携式设备、小型电源模块。

三、封装与物理特性

YSPI0740-100M采用一体成型SMD封装,物理特性适配现代电子制造需求:

  • 一体成型结构:无裸露线圈设计,相比传统绕线电感,抗机械振动、冲击能力更强(长期工作不易出现线圈松动),适合工业、车载等严苛环境(轻载场景);
  • 表面贴装(SMD):支持自动化贴装与回流焊,生产效率高,焊接可靠性稳定,减少人工成本;
  • 小尺寸设计:7.3×6.6×4mm的体积,可在紧凑电路板上灵活布局,尤其适合智能手机充电器、移动电源等小型化产品。

四、电气性能优势

从电气性能来看,该电感的设计针对性解决电源电路的关键痛点:

  1. 低损耗高效:51.5mΩ的DCR远低于同类普通功率电感,在4.5A额定电流下,功率损耗仅约1.04W(计算:I²R=4.5²×0.0515≈1.04W),温升控制更优,延长电源模块寿命;
  2. EMI抑制好:一体成型工艺减少了线圈的电磁辐射泄露,相比绕线电感,电磁干扰(EMI)更低,可简化后续EMI滤波电路设计,降低整体成本;
  3. 电流承载稳定:4.5A额定电流覆盖多数中小功率场景,满足日常负载波动需求(如路由器同时连接多设备时的电流变化)。

五、典型应用场景

基于参数与性能,YSPI0740-100M适用于以下常见场景:

  • 消费电子电源:手机/平板充电器、移动电源的DC-DC转换储能电感;
  • 通信设备:路由器、交换机、光模块的电源滤波/储能电路;
  • LED驱动电源:中等功率LED灯条、显示屏的驱动电感(4.5A电流可支撑多颗LED串联);
  • 小型工业设备:小型PLC、传感器模块的电源电路;
  • 车载电子(轻载):车载充电器、行车记录仪的辅助电源(需确认实际工况适配性)。

六、品牌与可靠性

益嘉源(YJYCOIN)作为国内专注电感研发的厂商,其产品在可靠性上具备以下特点:

  • 工艺成熟:一体成型电感采用高温烧结工艺(行业常规),确保电感值稳定,耐温范围广(一般-40℃~125℃,符合功率电感常规标准);
  • 环保合规:符合RoHS无铅环保要求,适配全球市场准入;
  • 批量一致性:量产产品参数一致性好,降低电路板调试难度,适合批量生产需求。

该电感凭借「小尺寸+高电流+低损耗」的组合优势,成为中小功率电源设计的实用选择,可有效平衡性能与成本。

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
