YSPI0730-6R8M 一体成型功率电感产品概述

一、核心参数总览

YSPI0730-6R8M是益嘉源(YJYCOIN)推出的一体成型功率电感,核心参数精准匹配中等功率电源电路需求,具体如下:

  • 电感值:6.8μH,精度±20%(满足多数电源设计的工程精度要求,无需额外冗余设计);
  • 额定电流:4.5A(指电感温升控制在安全范围的持续工作电流,电感值波动不超过20%,避免性能衰减);
  • 直流电阻(DCR):40mΩ(低电阻设计直接降低功率损耗,提升电源转换效率);
  • 封装规格:SMD表面贴装,尺寸为7.3mm(长)×6.6mm(宽)×3mm(高),紧凑小巧;
  • 产品类型:一体成型电感(绕组与磁芯通过树脂模压一体化封装,减少漏磁与电磁干扰)。

二、关键性能优势

该电感针对功率电路的核心痛点优化,具备以下实用优势:

  1. 低损耗高效能:40mΩ的低DCR配合4.5A额定电流,实际功率损耗仅约0.81W(公式:(P=I^2R)),可有效降低电源模块热耗散,提升整体转换效率5%~8%(对比同规格绕线电感);
  2. 低EMI易兼容:一体成型结构消除了绕线电感的磁芯间隙,漏磁率降低60%以上,减少对周边敏感电路的电磁干扰,简化系统EMI滤波设计;
  3. 高可靠性抗 harsh:模压封装提升机械稳定性,抗振动(10g~2000Hz)、抗冲击(1000m/s²)性能优于普通绕线电感,适合车载、工业等严苛环境;
  4. 小尺寸省空间:7.3×6.6×3mm的封装可兼容多数便携设备(笔记本、平板)及小型电源模块的PCB布局,比同参数绕线电感节省约15%的安装空间。

三、封装与机械特性

YSPI0730-6R8M采用SMD表面贴装封装,机械特性适配自动化生产:

  • 尺寸精度:长7.3mm±0.2mm、宽6.6mm±0.2mm、高3mm±0.2mm(满足SMT贴装的±0.1mm精度要求);
  • 封装工艺:树脂模压一体化(绕组与磁芯固化为整体,无外露绕组,避免短路风险);
  • 贴装兼容性:适配标准回流焊工艺(温度范围220℃~260℃),引脚设计符合IPC-J-STD-001标准,可与主流贴片机兼容。

四、典型应用场景

该电感的参数特性使其广泛覆盖以下中等功率电路:

  1. 便携设备电源:笔记本电脑、平板的DC-DC降压模块(如19V转5V、12V转3.3V);
  2. LED驱动电源:中功率LED照明(面板灯、台灯)的恒流/恒压驱动电路;
  3. 车载电子:车载导航、行车记录仪的12V转5V/3.3V电源模块;
  4. 小型工业电源:PLC辅助电源、传感器模块的DC-DC转换电路。

五、品牌与选型参考

YSPI0730-6R8M由益嘉源(YJYCOIN)生产,该品牌专注电感研发10余年,产品通过ISO9001、RoHS认证,供应链稳定;

选型参考:

  • 若需更高电流(5A~6A),可选择同系列YSPI0730-6R8H(额定电流5.5A);
  • 若需更小尺寸,可对比益嘉源YSPI0503系列(5×5×3mm);
  • 实际工作电流建议不超过额定电流的80%(降额设计),进一步提升可靠性。

该产品凭借“小尺寸、低损耗、高可靠”的特性,成为便携设备与小型电源设计的优选电感。

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
