FV43X333K202EGG 为 PSA(信昌电陶)系列高压贴片多层陶瓷电容(MLCC),主要参数如下:标称电容 33 nF,容差 ±10%,额定电压 2 kV DC,介质类型 X7R,封装尺寸 1812(约 4.6 mm × 3.2 mm)。该器件属于中高电压、较大电容量的表面贴装陶瓷电容,适用于对体积、耐压有较高要求的电路设计。
典型可靠性验证包括高温湿热偏压(THB)、温度循环、机械冲击/振动、焊接热稳定性和耐压、绝缘电阻等测试。X7R MLCC 在长期应力下可能出现容量衰减或开路风险,建议对关键电路进行加速寿命验证及批次抽样测试。
该型号常见为贴片卷带包装,便于 SMT 自动贴装;具体包装代码(如 EGG)请按厂家提供的物料表确认。采购时应注意:确认批次、出厂测试记录(耐压、容值、容差)、储存与运输条件(防潮、防震),并在关键应用场合进行来料电参数确认测试。
总结:FV43X333K202EGG 是一款面向中高压应用的 MLCC 解决方案,尺寸适合 SMT 生产,需在设计阶段充分考虑 X7R 的偏压/温度特性与 PCB 绝缘布线,以确保长期稳定可靠运行。若需更详细的电学、机械及可靠性数据,请联系供应商索取完整数据手册与偏压-温度表格。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
