LQW15DN100M00D 产品概述 — muRata 0402 封装 10µH 功率电感

一、产品简介

LQW15DN100M00D 是村田(muRata)推出的一款超小型功率电感,采用 0402(约 1.0 × 0.5 mm)贴片封装,名义电感值 10 µH,公差 ±20%。该器件面向对体积和空间高度受限的移动终端、可穿戴设备、微型电源模块以及高密度 PCB 电源滤波场合,侧重于在极小封装内实现滤波与能量存储功能。

二、主要参数

  • 电感值:10 µH(±20%)
  • 额定电流:120 mA
  • 饱和电流(Isat):120 mA
  • 直流电阻(DCR):5.405 Ω
  • 封装:0402(约 1.0 × 0.5 mm)
  • 品牌:muRata(村田)

三、性能与特性

  • 小体积:0402 封装适合高密度贴装与空间受限设计。
  • 能量存储能力:10 µH 电感值适合低频滤波和能量传输,但在仅 120 mA 的电流评级下,适用电流较小。
  • 饱和特性:Isat 与额定电流相同,意味着在接近额定电流时电感容易出现饱和,需谨慎留有裕量。
  • 损耗与效率:DCR 为 5.405 Ω,相对于大多数功率电感而言偏高,会带来显著的 I²R 损耗和热量产生,因此在需要高效率的 DC-DC 转换或较大纹波电流场合需评估功耗影响。

四、典型应用

  • 超小型电源滤波:输入/输出去耦与低频滤波。
  • 低功耗便携设备:用于对极小电流需求的传感器、时钟电路或低功耗子系统的磁性元件。
  • EMI 抑制与共模/差模滤波(在合适电流条件下)。
  • 不建议用于高电流或高功率转换器的主电感,除非电流需求远低于 120 mA。

五、PCB 布局与焊接建议

  • 布局:尽量靠近需要滤波的 IC 或电源引脚,缩短引线长度以降低寄生电感与噪声耦合。
  • 热管理:由于较高的 DCR,会产生明显热量;为避免温升,应保证周围有足够散热路径或采用热铜铺设。
  • 焊接:遵循村田推荐的无铅回流焊曲线,避免过高的温度或过长的保温时间造成机械应力或性能退化。
  • 机械应力:0402 封装脆弱,贴片与回流过程中避免强机械冲击与过度弯曲。

六、选型与注意事项

  • 电流裕量:实际应用中建议保留充分裕量(例如额定电流的 50%~100% 以上)以避免进入饱和区并减小损耗。
  • 损耗评估:在有显著纹波电流或连续负载电流时,必须计算 I²R 损耗与温升,确认不会超出可靠工作范围。
  • 频率响应:本概述未给出自谐频率(SRF)和频率相关的阻抗曲线;对高频滤波或谐波抑制的设计,应参考原厂数据手册并做实际测量校验。
  • 替代与兼容:若实际电流或效率要求更高,建议选用更大封装或更低 DCR、较高 Isat 的功率电感型号。

七、存储与可靠性

  • 存放环境应干燥、无腐蚀性气体,避免长时间在高温高湿下存放。
  • 贴片元件易受机械和热应力影响,建议遵循村田包装与储存指南,贴片后尽快焊接,避免长期暴露。

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
