NLCV32T-4R7M-PFR — TDK 4.7µH 绕线片式功率电感产品概述

一、产品简介

NLCV32T-4R7M-PFR 是 TDK 推出的绕线片式功率电感,封装为 1210(常见贴片尺寸),标称电感值 4.7µH,允许偏差 ±20%。该器件针对开关电源与电源滤波类应用优化,具备较高的额定直流电流与相对稳定的直流电阻特性,适用于对体积、效率与可靠性有平衡要求的场合。

二、主要电气参数

  • 标称电感:4.7 µH(±20%)
  • 额定电流:900 mA(额定工作电流,指在规定温升与电感衰减范围内能长期通过的直流电流)
  • 直流电阻(DCR):约 200 mΩ(影响功率损耗与转换效率)
  • 类型:绕线片式电感(功率用)
  • 封装:1210(适合标准贴片回流工艺)
  • 品牌:TDK

三、产品特性与优势

  • 功率特性:900 mA 级别的额定电流使其能胜任小功率到中等功率的降压、升压和滤波电路。
  • 损耗控制:200 mΩ 的 DCR 在同等级产品中处于合理区间,兼顾了温升与效率。
  • 稳定性:绕线结构在满足功率通流的同时,对电感值的温漂与电流偏置有较好表现(设计时仍需考虑直流偏置对电感的影响)。
  • 封装与可装配性:1210 贴片封装方便自动化贴装与回流焊,适合表面贴装生产线。

四、典型应用场景

  • DC–DC 降压/升压转换器中的能量储存与输出滤波
  • 电源输入滤波与去耦
  • LED 驱动与小型功率模块
  • 工业与消费电子中小功率电源管理

五、设计与使用建议

  • 电流余量:为保证长期可靠性,建议在额定电流下适当留有裕量(通常按 20–30% 余量设计),并验证在目标工作温度下的温升。
  • DCR 对效率影响:DCR 越大,铜耗越高,应在效率预算中考虑该项损耗;并在散热与布局上优化。
  • PCB 布局:将电感置于开关器件与输出电容之间,缩短高电流回路走线,减小回路面积以降低 EMI。
  • 直流偏置与饱和:绕线电感在高直流偏置下电感值会下降,关键设计应参考器件在实际偏置下的电感变化并做实验验证。
  • 焊接与可靠性:采用推荐回流曲线进行焊接,避免超温或长时高温对性能的影响。

六、可靠性与合规性

TDK 品牌供应链与品质保证体系成熟,器件通常满足 RoHS 等环保要求,并可提供相关可靠性与性能验证资料(如需更详细的机械尺寸、温升曲线或在偏置下的电感特性,建议从官方数据手册或代理商处获取完整规格书)。

如需针对具体电路(如某型号降压转换器)进行选型对比或热与效率评估,我可以基于您的应用条件(输入/输出电压、开关频率、纹波电流等)给出更具体的建议。

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
