Sumida CDRH127/LDNP-102MC 功率电感产品概述

一、产品核心定位与应用场景

CDRH127/LDNP-102MC是日本胜美达(Sumida)推出的小型化表面贴装(SMD)功率电感,属于CDRH127系列(12×12mm封装尺寸),专为低至中等功率的电源电路设计,兼顾体积紧凑性与性能稳定性。

其典型应用场景包括:

  1. 消费电子:笔记本电脑、平板电脑、智能穿戴设备的DC-DC降压/升压转换器;
  2. 小型工业设备:嵌入式控制器、传感器模块、小型PLC的电源滤波与储能;
  3. 通信终端:WiFi路由器、小型基站、IoT网关的电源供电电路;
  4. 汽车电子(辅助级):车载显示屏、USB充电口的低功率电源模块(需确认具体温湿度要求)。

二、关键电气性能参数解析

该电感的核心参数围绕“电源电路的储能、滤波与电流耐受”设计,具体解读如下:

1. 电感值与精度

  • 标称电感值:1mH(毫亨),属于中等电感范围,适合低频至中频(100kHz以下)电源电路的储能需求;
  • 精度:±20%,满足绝大多数常规电源设计的误差要求,无需高精度场景的额外成本,同时避免因精度过高导致的体积或成本增加。

2. 电流耐受能力

  • 额定电流(Irms):700mA:指连续工作时,电感线圈与磁芯的温升不超过胜美达规定的允许值(通常≤40℃),此时电感性能稳定,无明显性能衰减;
  • 饱和电流(Isat):860mA:磁芯饱和的临界电流——当电流超过此值,磁芯磁导率快速下降,电感值会降低约30%(具体以官方 datasheet 为准),直接影响电路稳压、滤波效果,设计时需确保峰值电流不超过此阈值。

3. 直流电阻(DCR)

  • 标称值:1.5Ω,是电感线圈的直流电阻,会产生铜损(I²R)。1.5Ω在1mH电感中属于合理范围,兼顾了电感储能能力与功率损耗,避免因DCR过高导致电源效率降低或发热严重。

三、物理特性与封装规格

1. 封装与尺寸

  • 封装类型:表面贴装(SMD),支持自动贴装,适合大规模生产;
  • 平面尺寸:12×12mm(长×宽),属于小型化设计,可适配高密度PCB布局;
  • 典型高度:约7mm(具体以官方 datasheet 为准,用户未明确给出高度时需标注“典型值”)。

2. 材料结构

  • 磁芯:采用胜美达定制的高饱和铁氧体磁芯,确保在额定电流下磁芯不饱和,同时降低磁损;
  • 线圈:漆包铜线绕制,绝缘性好,低损耗,耐温性符合工业级要求。

四、可靠性与适用环境

  1. 温度范围:支持**-40℃至+125℃**(胜美达同类产品常规范围),满足工业级设备的宽温需求,也适配消费电子的常规温湿度环境;
  2. 环保与认证:符合RoHS、REACH等环保标准,无铅无卤,适配全球市场要求;
  3. 可靠性测试:通过IEC 60068-2系列振动、冲击测试(如10G振动、100G冲击),适合 harsh 环境下的设备长期运行;
  4. 寿命:正常工作条件下(温度≤105℃),寿命可达5万小时以上,满足工业设备的长期稳定需求。

五、选型与使用注意事项

  1. 电流匹配:设计时需计算电路的峰值电流,确保不超过Isat(860mA),连续电流不超过额定电流(700mA),避免电感饱和或过热;
  2. 频率适配:1mH电感适合100kHz以下的电源电路,高频场景(如几百kHz以上)需选择更小电感值的型号;
  3. 空间确认:12×12mm封装虽紧凑,但需确认设备内部高度(典型7mm)是否符合布局要求;
  4. 精度需求:若需更高精度(如±10%),需选择胜美达同系列高精度型号,但成本会相应增加。

该产品是胜美达针对中等功率电源市场的高性价比方案,兼顾体积、性能与可靠性,广泛适用于消费电子、工业控制等多领域的电源设计。具体参数需以官方最新 datasheet 为准,选型时建议结合实际电路需求匹配。

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
