FV31X103K102ECG 为 PSA(信昌电陶)系列贴片多层陶瓷电容(MLCC),标称容量 10nF(103),容差 ±10%(K),额定电压 1kV DC,温度特性 X7R,封装尺寸 1206(3.2 × 1.6 mm)。该器件为通用型高压陶瓷片式电容,面向高压直流滤波、耦合、退耦与能量缓冲等应用场景。
封装为 1206(英制),外形尺寸约 3.2 × 1.6 mm,厚度随型号略有差异。为贴片式端接结构,适用于自动贴装与回流焊工艺。高压器件对焊点完整性和基板应力敏感,避免焊接后基板弯曲导致介质裂纹。
PSA 产品通常满足 RoHS/无铅工艺要求,常规出货前会进行外观检查、容量与容差测试、绝缘电阻/漏电流、耐压测试及焊接可靠性评估。用户可按需要求提供相关检验报告与可靠性试验记录。
总结:FV31X103K102ECG 是一款面向高压场景的通用型 10nF X7R MLCC,适用于空间紧凑且需高压承受的滤波与退耦场合。选型时重点关注 DC 偏压导致的容量衰减、焊接与机械应力防护以及是否需要安规认证。

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.
