LQW15CN1R0M10D 为村田(muRata)出品的小型功率电感,标称电感量 1.0 μH,公差 ±20%,额定电流 270 mA,直流电阻(DCR)约 940 mΩ,封装为 0402(1.0 × 0.5 mm)无屏蔽表面贴装型。该器件以体积小、便于贴装及适用于高密度 PCB 布局为特点,主要面向低功率电源滤波、去耦与 EMI 抑制等应用场景。
0402 封装优势在于占板面积小、适合自动化贴装,但相对机械强度与热容量较低。器件在反复热循环、机械冲击与高湿环境下的可靠性依赖于封装质量与焊接工艺。对于关键设备,建议做温度循环与湿热测试验证实际寿命。
当系统对功率损耗和压降敏感时,优先考虑 DCR 更低、额定电流更高的同系列或替代型号;当电磁兼容(EMC)或磁场耦合是关键问题时,优先选用屏蔽型电感或增加磁屏蔽措施。若需更精准的电感值或较小的电感变化,应选择更高精度(例如 ±10% 或 ±5%)的型号。
总结:LQW15CN1R0M10D 以其超小封装与中等电感值适合空间受限、功率较低的滤波与去耦应用,但需注意其较高的 DCR 与无屏蔽特性,在设计时应对电流承载、热管理与电磁耦合进行评估,确保可靠性与性能满足系统需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
