FV42X102K402EFQ 为 PSA(信昌电陶)系列高压多层陶瓷贴片电容(MLCC),标称容值 1nF,公差 ±10%,额定直流电压 4kV,介质材料为 X7R,封装形式为 1808。该产品针对需要高工作电压与体积受限场合的滤波、耦合与阻尼等应用而设计。
X7R 介质在 -55°C 至 +125°C 范围内表现出良好的温度稳定性,适合多数工业和电力类场合。需注意 MLCC 在高直流偏置下会出现容值下降现象,设计时应考虑有效电容随电压变化的影响。
典型应用包括高压开关电源、摄影闪光/点火电路、医疗/工业高压模块、通讯和雷达前端高压偏置电路等。
型号 FV42X102K402EFQ 的命名与封装、耐压、容值和公差紧密相关,批量采购前建议索取并核对厂家详细数据手册(包含温度系数曲线、直流偏置特性、尺寸图与焊接建议)以及实物样品做电气与可靠性验证。
如需进一步的性能曲线(例如容值随温度、电压的变化)或封装尺寸图,我可以协助整理并对比同类替代件,便于在具体应用中做出最优选型。

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.
