YSPIA1770-100M 功率电感产品概述

YSPIA1770-100M是益嘉源(YJYCOIN)推出的一款一体成型贴片功率电感,专为中大功率电子设备的电流滤波、能量存储场景设计,兼顾高电流承载能力与紧凑空间布局,适配工业电源、汽车电子等多领域应用需求。

一、产品基本定位

该电感属于SMD(表面贴装)系列,型号中“1770”对应封装尺寸(长18.25mm×宽17mm×高7mm),“100M”表示电感值为10μH(M代表±20%精度)。作为一体成型电感,其结构采用磁粉芯压制工艺,相比传统绕线电感具有磁漏低、抗振动、机械强度高的特点,适合严苛环境下的长期稳定工作。

二、核心性能参数详解

1. 电感值与精度

电感值为10μH ±20%,覆盖中功率电源设计的常规储能范围(如3.3V/5V转12V、12V转24V等DC-DC电路)。±20%的精度满足工业级设备的滤波需求,无需额外精密校准,降低系统设计复杂度。

2. 电流承载能力

  • 额定电流(Irms):10A:指电感持续工作时,电感值下降≤10%、表面温度不超过允许值(常规一体成型电感为100℃左右)的最大电流,可稳定支撑大电流输出场景;
  • 饱和电流(Isat):19A:指电感值下降≤30%的最大峰值电流,应对电路突发过载(如启动瞬间、负载波动)时仍能保持基本性能,避免电感失效导致电路故障。

3. 直流电阻(DCR)

DCR为9.3mΩ,属于同规格电感中的低损耗水平。低DCR可显著降低铜损(P=I²R),10A持续工作时铜损仅为0.93W,减少热量生成,提升电源转换效率(约提升1%~2%)。

4. 封装与尺寸

封装为标准SMD,尺寸18.25×17×7mm(长×宽×高),适配常规自动贴片机的贴装流程,且紧凑的体积可优化电路板布局,适合高密度集成设计。

三、主要应用场景

YSPIA1770-100M的性能特点使其适配多类高电流应用:

  1. 工业开关电源:DC-DC转换模块的储能电感,支撑10A以上持续输出,满足PLC、变频器等设备的电源需求;
  2. 汽车电子:车载充电器(OBC)、电机驱动电路(如电动座椅、车窗电机)的滤波组件,耐受汽车环境的温度波动与振动;
  3. 通讯设备:基站电源、服务器电源的滤波环节,稳定大电流输出,减少电磁干扰;
  4. 消费电子:大功率快充充电器(65W以上)、移动电源(高功率版本)的电感,提升充电效率与稳定性。

四、产品优势总结

  1. 低EMI与高可靠性:一体成型结构减少磁漏,电磁干扰(EMI)比绕线电感低30%以上,且磁芯与线圈一体化,抗振动、抗冲击能力强,适合工业/汽车等严苛环境;
  2. 高电流效率:低DCR(9.3mΩ)+ 高饱和电流(19A),兼顾持续工作效率与过载保护,降低系统散热成本;
  3. 紧凑空间设计:18.25×17×7mm的小尺寸,比同电流等级的传统电感体积缩小约20%,适配小型化设备需求;
  4. 贴片兼容性:标准SMD封装,可通过回流焊工艺批量生产,提高生产效率,降低人工成本。

五、选型与应用注意事项

  1. 电流匹配:实际工作电流需控制在10A以内(持续),峰值电流不超过19A,避免电感值大幅下降影响电路性能;
  2. 温度控制:工作环境温度建议在-40℃~125℃范围内(一体成型电感常规工作温度),若环境温度较高,需预留散热空间;
  3. 布局建议:避免靠近发热元件(如功率MOS管),贴装时确保引脚焊接牢固,防止虚焊导致电阻增大;
  4. 精度需求:若需更高精度(如±10%),需确认益嘉源是否有对应衍生型号,本产品±20%适配常规场景无需升级。

该电感凭借高电流承载、低损耗、紧凑体积等特点,成为中大功率电子设备的优选功率电感之一,可有效提升系统稳定性与效率。

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
