GRM1557U1A472JA01D 为 muRata(村田)生产的一款0402(工业标准 0402 / 公制 1005)贴片多层陶瓷电容(MLCC)。该型号标称容量为 4.7nF,精度 ±5%,额定直流电压 10V,温度系数由厂商编码 U2J 表示。凭借超小封装与稳定的电气特性,适用于空间受限的便携式与高密度电路板设计。
这些参数决定了该器件在低压、对体积敏感的电子系统中有良好的滤波、去耦、旁路与交流耦合能力。
如需,我可以帮助查询该型号的村田数据表关键曲线(温漂、直流偏置、等效串联电阻/电感)并对比常见替代件。

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.
