FM43X104K501EFG是PSA信昌电陶推出的一款中高压多层陶瓷贴片电容(MLCC),针对工业级、车载及部分消费电子场景的高压滤波、耦合需求设计,核心参数与封装规格明确,可靠性适配主流应用环境。
该型号的关键参数可通过命名与规格清晰对应:
X7R介质的平衡优势
X7R属于铁电陶瓷介质,相比高精度NPO(COG)介质成本更低、容值密度更高;相比低成本Y5V介质,温度稳定性显著提升(Y5V温度范围-30℃~+85℃,容值变化±22%),适合对温度稳定性有基础要求但无需极端精度的场景。
500V中高压适配
该型号额定电压达500V DC,属于MLCC中高压范畴,可稳定承受电源电路中的高压纹波、耦合电路中的峰值电压,避免电压击穿风险(注意:交流应用需降额至1/2~1/3直流额定电压)。
1812封装的工艺兼容性
1812封装体积小巧,适配自动化SMT贴装,减少人工成本;焊盘尺寸符合行业标准,可兼容主流贴片机与PCB设计,适合高密度电路布局。
可靠的电性能一致性
每批产品经严格筛选,容值、损耗因子(DF)、绝缘电阻等参数一致性高,长期工作无明显容值衰减,符合RoHS环保要求。
该型号因高压、稳定特性,广泛应用于以下场景:
PSA信昌电陶是国内MLCC行业的成熟厂商,该型号通过ISO9001质量体系认证,部分批次符合AEC-Q200车载级标准;生产过程采用自动化叠层、烧结工艺,每批产品经电性能、机械强度、环境可靠性测试,确保交付一致性。
该型号以高性价比、稳定可靠的特性,成为中高压MLCC应用中的主流选型之一。

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.
