FV31X223K102EEG 为 PSA(信昌电陶)系列的一款高压多层陶瓷贴片电容(MLCC),标称容量 22 nF(223),容差 ±10%(K),额定直流电压 1 kV,温度特性等级 X7R,常见封装 1206(公制约 3.2 mm × 1.6 mm)。该器件为面向中高压应用设计,在体积、耐压与成本之间取得平衡,适合需要耐压性与中等介电稳定性的多种电路场景。
结语:FV31X223K102EEG 在 1 kV 等级的 MLCC 里以较小封装提供较高电容,是高压滤波与耦合的常用选择。设计时需重点关注 X7R 的温漂与 DC 偏压特性、PCB 工艺与机械应力控制,并参考厂商提供的详细曲线与工艺规范以确保可靠性。

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.
