FV42N221J302EFG是信昌电陶(PSA) 推出的一款高压多层陶瓷贴片电容(MLCC),专为高耐压、高稳定性场景设计。核心参数覆盖220pF容值、±5%精度、3kV额定电压及C0G(NP0)温度系数,封装采用1808英寸制,适用于工业、医疗、电源等领域的高压电路需求。
型号“FV42N221J302EFG”各部分含义:
C0G是温度稳定型陶瓷介质,具有三大核心优势:
FV42N221J302EFG主要适用于高压、高稳定性场景:
高压电容需严格降额使用,建议实际工作电压≤2.1kV(70%额定电压),避免长期高压导致介质老化;
贴装后避免PCB剧烈弯曲,振动环境下需增加固定措施(如点胶)。
FV42N221J302EFG凭借高耐压、高稳定性、小体积等核心优势,成为工业、医疗、电源等领域高压电路的理想选择。结合PSA的专业制造能力,产品可满足严苛的可靠性与环境要求,是替代进口高压MLCC的高性价比方案。

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.
