FM43X104K501EFG 贴片陶瓷电容(MLCC)产品概述

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。

一、产品基本属性及核心参数

该型号的关键参数可通过命名与规格清晰对应:

  • 类型:多层陶瓷贴片电容(MLCC),采用多层叠层工艺提升容值密度;
  • 容值:100nF(命名中“104”代表10×10⁴ pF,即100nF);
  • 精度:±10%(命名中“K”为精度代码,对应±10%误差范围);
  • 额定电压:500V DC(直流额定电压,是长期工作的安全电压上限);
  • 温度系数:X7R(陶瓷介质类型,温度特性为-55℃~+125℃范围内,容值变化≤±15%);
  • 封装:1812(英制尺寸,公制约4.5mm×3.0mm×1.5mm,适配表面贴装工艺);
  • 品牌:PSA信昌电陶(国内MLCC主流制造商,专注中高压产品研发)。

二、关键特性解析

  1. 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。

  2. 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)。

  3. 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。

  4. 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。

三、典型应用场景

该型号因高压、稳定特性,广泛应用于以下场景:

  1. 电源电路:开关电源/线性电源的高压滤波(如输出端纹波抑制)、升压电路的耦合;
  2. 工业控制:PLC、变频器、伺服驱动器的信号滤波与耦合,适配工业环境宽温需求;
  3. 车载电子:车载充电器、车载信息系统的高压部分(如12V/24V升压电路),符合车载级可靠性要求;
  4. 通信设备:基站电源、光纤收发器的滤波电路,适配高密度PCB设计;
  5. 高端家电:变频空调、洗衣机控制板的高压滤波,提升电路稳定性。

四、选型与使用注意事项

  1. 电压匹配:电路最大直流电压需低于500V,交流应用需降额(如250V AC峰值以内);
  2. 温度范围:确认工作环境温度在-55℃~+125℃内,超出需考虑X8R等高温介质;
  3. 精度需求:±10%精度满足大部分滤波场景,若需更高精度(±5%)需换“J”精度代码产品;
  4. 封装兼容性:确认PCB焊盘尺寸与1812封装匹配,避免焊接虚焊、假焊。

五、品牌质量保障

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。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
