FM31X224K251EEG 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

FM31X224K251EEG是PSA信昌电陶推出的中高压贴片多层陶瓷电容(MLCC),型号编码直接传递核心参数:

  • 容值:224→22×10⁴ pF=220 nF
  • 精度:K→±10%
  • 额定电压:251→直流250 V
  • 封装:1206(英制12×6mil,对应公制3.2mm×1.6mm)
  • 温度系数:X7R(宽温特性)

产品采用贴片封装,适配自动化表面贴装工艺,主要用于需要中高压、稳定容值的电子电路。

二、核心技术参数详解

  1. 容值与精度:标称220 nF,误差±10%,满足工业级、消费电子电路的滤波/耦合需求,无需额外匹配高精度元件。
  2. 电压特性:直流250 V额定电压,可承受短时间过压(峰值≤300 V),适配开关电源、LED驱动等中高压场景。
  3. 温度稳定性:X7R系数,工作温度-55℃~+125℃,全温区容值变化≤±15%,远优于普通Y5V电容,适合户外/车载宽温环境。
  4. 封装与尺寸:1206封装(典型厚度1.0mm),体积紧凑,节省PCB空间,适配高密度集成设计。
  5. 可靠性指标:1kHz/25℃下损耗角正切值(tanδ)≤0.02(低损耗);125℃/250V负载下,寿命≥1000小时,满足长期稳定运行。

三、典型应用场景

该产品因中高压、宽温稳定特性,广泛覆盖以下领域:

  1. 电源电路:开关电源输出滤波、输入EMI滤波,LED驱动电源储能稳压,适配250V电压等级。
  2. 工业控制:PLC、变频器、伺服驱动器的控制电路滤波,适应-40℃~+85℃工业现场环境。
  3. 消费电子:家电(空调/洗衣机)电源模块滤波,机顶盒/路由器信号耦合,提升抗干扰能力。
  4. 汽车电子:车载充电器(OBC)、信息娱乐系统电源滤波,符合汽车级-40℃~+125℃宽温要求。
  5. 通信设备:基站电源、光纤收发器去耦电路,减少电源纹波对信号传输的干扰。

四、产品优势与特点

  1. 宽温稳定性:X7R系数确保全温区容值波动小,避免电路性能因温度漂移。
  2. 中高压适配:250V额定电压覆盖多数中功率电路,无需并联低电压电容,简化设计。
  3. 紧凑封装:1206封装体积小,降低PCB布局成本,适配高密度集成。
  4. 高可靠性:PSA成熟工艺实现低损耗、抗老化,适合工业/汽车长期运行场景。
  5. 自动化适配:贴片封装支持高速贴装,提升生产效率,降低人工成本。

五、使用与储存注意事项

  1. 焊接工艺:推荐回流焊(峰值≤260℃,时间≤10s)或波峰焊(温度≤240℃,时间≤5s),避免高温开裂。
  2. 储存条件:未开封产品存于0℃~40℃、湿度≤60%环境,开封后建议1个月内用完,防止受潮。
  3. 机械应力:贴装避免过大压力,焊接后不弯曲PCB,防止MLCC开裂。
  4. 极性:无极性设计,安装无需区分正负极,简化电路设计。

总结

FM31X224K251EEG作为PSA信昌电陶的中高压MLCC,凭借宽温稳定、高耐压、紧凑封装等优势,成为工业控制、电源电路、汽车电子等领域的可靠选择,适配自动化生产,满足多场景性能需求。

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
