FS55X476K250LRG 多层陶瓷电容器(MLCC)产品概述

FS55X476K250LRG是PSA信昌电陶推出的一款常规温度特性多层陶瓷电容器(MLCC),针对电子设备的电源滤波、信号耦合、储能等核心需求设计,以紧凑的2220封装实现高容值密度,适配多场景下的小型化与可靠性要求。

一、产品基本属性

该产品属于常规温度类MLCC,核心属性明确:

  • 生产厂商:PSA信昌电陶(国内专业陶瓷元器件制造商,产品覆盖消费、工业、汽车等领域)
  • 封装规格:2220(英制封装,对应公制尺寸约5.7mm×5.0mm,厚度依型号多为1.2mm,符合IPC标准)
  • 介质类型:X7R(常规温度陶瓷介质)
  • 应用定位:通用型MLCC,适配电源滤波、信号耦合、旁路、储能等场景

二、核心性能参数

FS55X476K250LRG的关键参数精准匹配通用电子设备需求:

  1. 容值与精度:标称容值47μF(标识“476”即47×10⁶pF),精度±10%(标识“K”),满足电源滤波、低频耦合等对精度要求适中的场景;
  2. 额定电压:25V(标识“250”,直流工作电压上限),支持3.3V/5V等常规低压电源电路;
  3. 温度特性:X7R介质,工作温度范围-55℃~+125℃,容值变化率≤±15%(行业标准),适配宽温环境;
  4. 封装尺寸:2220(长5.7mm±0.2mm,宽5.0mm±0.2mm),焊盘需匹配IPC-7351标准以保证焊接可靠性。

三、设计特点与优势

  1. 高容值密度:2220封装实现47μF容值,比同尺寸铝电解电容容值密度提升约30%,可减少PCB占用面积,助力智能手机、智能穿戴等小型化设备设计;
  2. 稳定温度表现:X7R介质的宽温范围与低容值漂移,避免电解电容因温度变化导致的容值衰减,适合车载信息娱乐系统等温度波动场景;
  3. 低损耗性能:MLCC固有的低ESR(等效串联电阻)与低ESL(等效串联电感),提升高频滤波效果,降低开关电源、射频前端的电路功耗;
  4. 长寿命可靠性:陶瓷介质无电解液干涸、极化失效问题,高温高湿(85℃/85%RH)环境下典型寿命超10000小时,远高于铝电解电容;
  5. 环保合规:符合RoHS 2.0、REACH标准,无铅无卤,适配全球市场环保要求。

四、典型应用场景

FS55X476K250LRG的参数特性使其覆盖多领域通用设备:

  1. 消费电子:智能手机、平板电脑的DC-DC输出滤波、音频信号耦合;
  2. 工业控制:小型PLC、传感器模块、变频器的旁路滤波、信号耦合;
  3. 通信设备:路由器、交换机的电源滤波、射频信号旁路;
  4. 物联网终端:智能门锁、智能家居控制器的储能与滤波(尺寸小适配小型化设计);
  5. 车载电子:车载信息娱乐系统、行车记录仪的电源电路(需确认车规适配性)。

五、可靠性与环境适应性

  1. 温度耐受:-55℃~+125℃工作范围,满足户外物联网终端低温、工业设备高温场景;
  2. 机械稳定性:符合IEC 60068-2-6(振动)、IEC 60068-2-27(冲击)标准,抗运输与使用中的机械应力;
  3. 湿度耐受性:陶瓷封装防潮性优异,符合IEC 60068-2-60(湿热)标准,可在湿度≤95%环境稳定工作;
  4. 焊接可靠性:无铅端电极设计,适配回流焊、波峰焊工艺,焊接合格率≥99%。

六、选型与替换注意事项

  1. 容值匹配:替换需保证47μF±10%,偏差过大可能导致滤波失效或信号失真;
  2. 电压升级:若存在电压尖峰(如开关电源),建议选35V或更高电压等级产品;
  3. 温度适配:超125℃需换X8R介质(-55℃~+150℃),精度要求±5%需选J级产品;
  4. 封装兼容:焊盘建议长6.0mm、宽5.3mm,避免焊盘过大短路或过小虚焊。

总结

FS55X476K250LRG作为PSA信昌电陶的通用型MLCC,以紧凑封装、稳定性能与高可靠性,成为消费电子、工业控制等领域的主流选择。其参数适配性强,可满足大多数低压电子设备的电源与信号处理需求,是小型化设计中替代铝电解电容的理想方案。

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
