CDRH74NP-101MC-B 产品概述

一、基本参数

  • 型号:CDRH74NP-101MC-B(Sumida / 胜美达)
  • 电感值:100 μH,公差 ±20%
  • 额定电流:600 mA
  • 直流电阻(DCR):610 mΩ(典型值,通常在20°C测量)
  • 类型:磁胶屏蔽电感(功率电感)
  • 封装:SMD,外形尺寸 7.3 × 7.3 mm

二、主要特性

  • 高电感值:100 μH 提供良好的低频滤波与能量储存能力,适合需要较大电感的功率滤波场合。
  • 磁胶屏蔽结构:降低对周围电路的磁干扰,便于在密集布板环境中并列放置或靠近敏感器件。
  • 适用于表面贴装工艺:SMD 封装有利于自动化贴装与回流焊接,提升生产效率。
  • 适中 DCR 与额定电流:610 mΩ 与 600 mA 的组合适合中小功率应用,需在设计中关注功耗与温升。

三、典型应用

  • 开关电源(DC-DC)输入/输出滤波与储能元件
  • 电源噪声抑制与共模/差模滤波网络
  • LED 驱动电路与驱动电源滤波
  • 消费类电子设备的电源模块、模块化电源与电池供电系统
  • 需要磁屏蔽且体积受限的工业与通信设备的电源滤波

四、设计使用要点

  • 电流余量与磁饱和:额定电流 600 mA 为允许通流水平,实际设计建议留有裕量(例如在 50–80% 额定电流区间工作)以避免磁芯饱和和过高温升。
  • 损耗与效率:DCR 610 mΩ 在高平均电流或大纹波电流下会产生明显I2R损耗,需评估热升与系统效率影响。
  • 纹波电流与温升:在开关电源中,请关注交流纹波分量对发热的贡献,必要时进行热仿真或样机测量。
  • 布局建议:靠近电源开关器件与输入/输出电容进行最短回流路径铺线,避免形成大环路以减少 EMI。屏蔽结构有助于降低对周边元件的干扰,但仍需合理间距与屏蔽措施配合。

五、封装与焊接注意

  • 表面贴装(SMD)封装便于回流焊接,焊接时请参考厂家的回流曲线与焊盘推荐尺寸,避免过热导致性能退化。
  • 焊盘设计与粘贴助焊膏量会影响焊点质量与热传导,应在样机阶段验证焊接可靠性。
  • 机械应力:避免在装配或测试过程中对器件施加过大机械力(尤其是侧向),以免引起基座或引脚损伤。

六、选型与采购建议

  • 在最终选型前,请仔细查阅 Sumida 官方规格书以确认所有电气、机械与环境参数(如自谐频率、饱和电流、耐温等级及RoHS/无铅合规性)。
  • 对于关键电源通道,建议采购样品并在目标系统进行实际测量(DCR、温升、频率响应、EMI)以验证满足设计要求。
  • 考虑库存与替代品:若后续产能或交期受限,可同时评估同类封装和相近参数的替代型号,注意比较饱和特性与损耗差异。

以上为 CDRH74NP-101MC-B 的简明概述与工程选用建议,如需详细电气特性曲线、焊盘尺寸图或温升试验数据,请提供是否需要我检索或直接查看厂商资料表(Datasheet)。

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
