NLCV32T-6R8M-EFR 产品概述
一、产品简介
TDK NLCV32T-6R8M-EFR 是一款面向开关电源与电源滤波的表面贴装功率电感，标称电感值 6.8 μH，公差 ±20%，额定直流电流 700 mA，直流电阻 (DCR) 约 290 mΩ，封装为 1210（常见尺寸约 3.2 × 2.5 mm）。该器件以体积小、工艺兼容性好、适用于紧凑型电源模块为特点，适合各类便携与嵌入式电源设计。
二、关键参数说明
- 电感值：6.8 μH（±20%），实际工作电感可能在约 5.44–8.16 μH 范围内；
- 额定电流：700 mA，为制造商给出的参考持续电流值，超过此值时需关注磁饱和与温升；
- DCR：290 mΩ，导致直流损耗约 Pcu = I^2·R ≈ 0.7^2×0.29 ≈ 0.14 W（在额定电流下）；
- 封装：1210 型 SMD，便于高速贴装与回流焊工艺。
三、主要特点与优势
- 小型化封装，利于高密度 PCB 布局与空间受限产品；
- 适合中低功率 DC-DC 降压/升压转换器和电源滤波器；
- 中等 DCR 与适中的电流容量，在效率与尺寸之间取得折衷；
- 标准 SMD 封装便于自动化贴装、回流焊一体化生产。
四、典型应用场景
- 移动设备、便携式仪器、物联网终端的电源模块；
- 小功率 LED 驱动与背光电源；
- 板级电源滤波（输入或输出端）与降压转换器（buck）电感；
- 各类需要 EMI 滤波与能量储存的嵌入式系统。
五、选型与设计建议
- 考虑电流余量：额定 700 mA 为制造商标称值，建议在设计时保留 20–50% 余量以避免磁饱和与过热，若工作电流接近额定值应选择更高电流规格的电感；
- 注意温升与损耗：DCR 290 mΩ 在高占空比或持续大电流下会产生显著热量，应评估散热路径和周边元件温度；
- 关注磁饱和与交流性能：在高纹波电流或短路瞬态下，需参考厂家资料中的饱和电流（Isat）与自谐频率（SRF）等详细参数；
- 布局建议：电感与开关器件距离尽量短、走线宽短并增加过孔以降低寄生阻抗，确保输入与输出旁路电容靠近开关节点。
六、可靠性与工艺注意
- 支持常规回流焊工艺，但请参考 TDK 的焊接曲线与推荐温度限制以避免性能退化；
- 存储与工作环境可能影响电感值与 DCR，长期高温或高湿环境下应做可靠性验证；
- 在关键应用中，建议获取并核对 TDK 正式 datasheet，确认饱和电流、温度系数、储能等完整规格。
总结：NLCV32T-6R8M-EFR 是一款适合中低功率开关电源与滤波用途的小型功率电感，兼顾尺寸与性能。在实际设计中应结合电流裕量、热管理与饱和特性进行综合评估，必要时参照原厂 datasheet 获取完整电气与热学参数。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
