LQW15AN62NG00D 产品概述
一、概览
LQW15AN62NG00D 为村田（muRata）品牌的0402封装非屏蔽功率电感，标称电感值 62 nH，公差 ±2%，额定电流 145 mA，直流电阻（DCR）1.82 Ω。该器件体积小、适合高密度贴片电路，用于高频去耦、滤波和小功率电源回路。
二、主要电气特性
- 电感值：62 nH（±2%），适用于射频及高频去耦场合。
- 额定电流：145 mA，超过该电流时电感值会因磁饱和和温升而下降。
- DCR：1.82 Ω，较高的直流电阻意味着在直流或低频大电流应用时会产生明显压降和发热，应注意功耗预算。
- 类型：非屏蔽（unshielded），磁泄露比屏蔽型大，需注意邻近元件的磁干扰。
三、典型应用场景
- 高频开关电源的输出滤波与去耦（小功率模块、便携式设备）。
- EMI/EMC 抑制网络与共模/差模滤波前级。
- 射频匹配或高频滤波电路中用作小值电感元件。
- 空间受限、对电流要求不高的移动设备与传感器模块。
四、设计与布局建议
- 将电感尽量靠近被滤波的器件（例如稳压芯片、IC）以缩短寄生回路面积，降低噪声发射。
- 由于为非屏蔽型，避免并列放置在敏感模拟或高频接收通道附近，必要时改用屏蔽型或隔离。
- 考虑 DCR 带来的电压降与发热，若电流接近额定值，应选择更低 DCR 或更大封装型号以降低功耗。
- 注意 DC 偏置下电感值下降的特性，实测电路中的有效感量以确保滤波性能。
五、使用与可靠性注意事项
- 推荐按制造商提供的回流焊温度曲线进行贴片焊接，避免超过温度极限导致电感参数漂移。
- 焊接后建议做电感值和DCR抽样测试，校验参数是否在规格内。
- 储存时防潮防尘，遵循元器件保质期与包装规范。
- 对于需要更高电流承载或更低 DCR 的方案，可选用更大封装（如0805、1206）或屏蔽型功率电感替代。
六、采购与替代
订购时请使用完整料号 LQW15AN62NG00D 并确认包装（卷带）与批次。若电流或DCR要求更严格，可咨询村田或供应商推荐相近电感值但更高额定电流/更低DCR的替代型号。
总结：LQW15AN62NG00D 适合对体积有严格限制且工作电流较低的高频滤波与去耦场合。设计时重点关注其较高 DCR 与非屏蔽特性，合理布局与热管理可保障稳定性能。

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.
