YJYCOIN YSPI0730-100M 功率电感产品概述

一、产品基本定位

YSPI0730-100M是益嘉源(YJYCOIN) 推出的一款一体成型贴片功率电感,专为中等功率电子电路设计,兼顾小尺寸、低损耗与高可靠性,适用于消费电子、车载、工业控制等领域的电源转换及滤波场景。

二、核心性能参数解析

该电感的关键参数围绕“功率适配性”与“效率优化”设计,具体如下:

1. 电感值与精度

标称电感值为10μH,精度±20%(即实际电感值范围8μH~12μH),满足大多数DC-DC转换器、滤波电路的电感量需求——既避免过高精度带来的成本冗余,又能稳定匹配电路拓扑结构。

2. 额定电流与发热控制

额定电流为4A(持续工作电流),是指在环境温度≤125℃时,电感本体温度上升不超过35℃的最大电流。若实际工作电流低于4A,电感发热可控;若短时间过载(如脉冲电流),需结合散热设计评估,但长期超额定电流会导致电感值漂移、DCR增大,甚至损坏。

3. 直流电阻(DCR)

直流电阻为60mΩ(典型值),属于同类小尺寸电感中的低损耗水平。DCR直接影响导通损耗(P=I²·R),60mΩ的阻值可将4A电流下的导通损耗控制在0.96W以内,显著提升电源转换效率,减少系统发热。

三、封装与机械规格

YSPI0730-100M采用SMD贴片封装,具体尺寸为7.3mm(长)×6.6mm(宽)×3mm(高),属于紧凑型封装:

  • 一体成型结构:绕组完全包裹在磁芯材料中,屏蔽电磁干扰(EMI)效果优于开放式绕线电感,减少对周边敏感电路的干扰;
  • 机械强度高:耐振动(振动频率20Hz~2000Hz,加速度10g)、耐冲击(冲击加速度50g),适合车载、工业设备等恶劣环境;
  • 贴片兼容性:引脚间距适配常规SMT贴片机,支持回流焊工艺,可直接集成于PCB板,提高生产效率。

四、主要应用领域

结合参数特性,该电感广泛应用于以下场景:

  1. 消费电子电源:手机快充模块、平板电脑、笔记本电脑的DC-DC降压电路(如5V→3.3V/4A转换);
  2. 车载电子:LED车灯驱动、车载传感器电源、中控系统的辅助电源模块(耐振动需求);
  3. 工业控制:小型PLC、伺服驱动器的滤波电路、低功率电机驱动电源;
  4. 通信设备:路由器、交换机的电源模块滤波,减少信号干扰。

五、产品核心优势

  1. 低损耗与高效率:60mΩ低DCR+4A额定电流,适合中等功率转换,降低系统功耗;
  2. EMI屏蔽性好:一体成型结构减少电磁辐射,简化电路EMI设计;
  3. 小尺寸省空间:7.3×6.6×3mm封装,适配便携式设备的小型化需求;
  4. 高可靠性:磁芯与绕组一体化,避免振动导致的绕组松动,延长使用寿命;
  5. 成本可控:±20%精度与常规封装,平衡性能与成本,适合批量应用。

六、选型与使用注意事项

  1. 电流匹配:实际工作电流需≤4A(持续),脉冲电流需结合厂家给出的“饱和电流”参数评估(通常饱和电流略高于额定电流);
  2. 温度环境:工作环境温度建议≤105℃(长期),避免高温导致磁芯性能下降;
  3. 焊接工艺:回流焊温度需遵循厂家规范(如峰值温度≤245℃,时间≤30s),避免过热损坏;
  4. PCB设计:建议在电感下方预留散热焊盘,或在周边布局散热铜箔,降低本体温度。

综上,YSPI0730-100M是一款兼顾性能、尺寸与成本的实用型功率电感,可满足多数中等功率电子设备的电源设计需求。

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
