FM21N101J501PXG 片式陶瓷电容产品概述

一、核心参数与规格定义

FM21N101J501PXG为PSA(信昌电陶)推出的C0G类多层片式陶瓷电容(MLCC),核心参数基于工业级设计,具体规格如下:

  • 容值与精度:容值100pF(三位数字标识“101”:前两位有效数10,第三位倍率10¹),精度±5%(标识“J”),满足常规电路对容值稳定性的需求;
  • 额定电压:直流额定工作电压(WVdc)500V,支持中高压电路场景;
  • 温度特性:C0G温度系数(属NP0类),-55℃~+125℃范围内容值变化率≤±30ppm/℃,温度稳定性优异;
  • 封装尺寸:0805(EIA标准),对应公制尺寸2.0mm×1.25mm,适配常规SMT产线贴装;
  • 介质类型:C0G陶瓷介质,低损耗、高频特性好。

二、关键特性解析

该产品针对中高压、宽温、高频场景优化,核心特性包括:

  1. 宽温下的容值稳定性
    C0G温度系数使产品在极端温度环境(如工业高温区、户外设备)中容值漂移极小,避免因温度变化导致电路性能波动(如滤波截止频率偏移、信号耦合效率下降)。

  2. 低损耗与高频适配性
    介质损耗角正切值(tanδ)≤0.15%(1kHz,25℃),在射频、微波电路中信号衰减小,适合信号耦合、阻抗匹配等高频应用。

  3. 中高压耐受能力
    500V WVdc额定电压无需串联多个低耐压电容,简化电路设计,同时通过PSA的高温寿命测试(125℃/500V 1000h),确保长期高压下的可靠性。

  4. 小型化与焊接兼容性
    0805封装体积小,适配高密度PCB设计(如便携式设备、通信基站模块);端电极采用“银-镍-锡”三层结构,增强焊接附着力,兼容回流焊(峰值温度≤245℃)、手工焊工艺。

三、典型应用场景

该产品广泛应用于需要中高压、稳定容值、宽温可靠的领域:

  • 工业控制:PLC电源模块高压滤波、电机驱动EMI抑制、工业传感器信号处理电路;
  • 通信设备:基站射频前端信号耦合、光纤收发器电源滤波、5G小基站阻抗匹配;
  • 消费电子:中高压快充适配器EMI滤波、智能家居高压传感器信号传输;
  • 汽车电子(若符合车规延伸):车载电源辅助滤波、车身控制模块(BCM)信号滤波(耐受-40℃~+85℃宽温)。

四、可靠性与质量标准

PSA针对该产品执行严苛的可靠性测试,符合国际/国内标准:

  • 测试项目:温度循环(-55℃~+125℃ 500次)、湿度加载(85℃/85%RH/500V 1000h)、高温存储(150℃ 1000h);
  • 测试结果:容值变化率≤±5%,绝缘电阻≥10⁹Ω,无击穿/开路失效;
  • 标准 compliance:IEC 60384-20、GB/T 2693、RoHS 2.0(无铅环保)。

五、选型与应用注意事项

  1. 电压降额:实际工作电压不超过额定电压的80%(≤400V),脉冲峰值电压≤额定电压1.5倍(≤750V),避免过压击穿;
  2. 焊接防护:回流焊峰值温度≤245℃,手工焊温度≤350℃(焊接时间≤3s),防止陶瓷开裂;
  3. 静电防护:C0G电容对ESD敏感,操作时佩戴防静电手环,存储于防静电包装(湿度≤60%RH,温度25℃±5℃);
  4. 电路布局:高频应用时电容靠近负载端,减少引线长度以降低寄生电感;避免与大功率器件近距离放置,防止热干扰。

FM21N101J501PXG凭借稳定的温度特性、中高压耐受能力及小型化设计,成为工业、通信等领域中高压滤波、信号耦合场景的高性价比选择。

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
