FS46X105K251EFG 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心参数总览

FS46X105K251EFG是PSA(信昌电陶)推出的高压商用级贴片多层陶瓷电容(MLCC),针对中高压、宽温区电路场景优化设计,核心参数清晰明确:

  • 产品类型:贴片多层陶瓷电容(MLCC)
  • 品牌:PSA(信昌电陶)
  • 型号:FS46X105K251EFG
  • 容值:1μF(编码“105”=10×10⁵ pF)
  • 容值精度:±10%(字母标识“K”,商用级常规精度)
  • 额定电压:250V DC(编码“251”=25×10¹ V)
  • 温度系数:X7R(-55℃~+125℃内,容值变化率≤±15%)
  • 封装尺寸:1825英制(公制≈4.57mm×6.35mm,厚度≈1.2mm)
  • 辅助标识:“EFG”为生产批次、编带包装相关信息,不影响电气性能

二、关键性能与技术特性

该型号依托PSA成熟的MLCC生产工艺,具备以下核心优势:

  1. 宽温区稳定性
    X7R介质是平衡容值稳定性与成本的主流选择,FS46X105K251EFG在-55℃至125℃范围内,容值变化控制在±15%以内,可有效避免环境温度波动导致的电路性能漂移,适配工业、车载(若符合车规)等复杂场景。

  2. 中高压可靠性
    额定电压250V DC满足多数中高压电路需求,直流工作电压下无明显容值衰减;长期应用建议工作电压不超过200V DC(额定电压80%降额),进一步降低失效风险。

  3. 高频特性均衡
    MLCC本身的低等效串联电阻(ESR)、低等效串联电感(ESL)特性,使该型号适合高频滤波、耦合、去耦等应用;1825封装优化了电极设计,在10MHz~100MHz频段内损耗稳定。

  4. 批量一致性
    ±10%的容值精度属于商用级标准,PSA通过严格的生产管控确保批量产品的容值、电压特性一致性,减少电路调试难度。

三、封装与物理规格

  1. 封装尺寸
    1825英制封装(行业通用编码),公制参数为:
  • 长度:4.57mm±0.2mm
  • 宽度:6.35mm±0.2mm
  • 厚度:1.2mm±0.1mm(具体需参考PSA官方 datasheet)
  1. 端电极与焊接
    采用镍/锡(Ni/Sn)镀层端电极,兼容无铅回流焊工艺,焊接强度符合IPC标准;镀层抗硫化性能良好,降低存储/使用中的电极氧化风险。

  2. 包装方式
    常规采用12mm编带卷盘包装,每盘10000片,适合SMT自动化贴装,编带张力、抗静电性能符合电子元器件包装规范。

四、典型应用场景

FS46X105K251EFG的参数特性使其适配以下场景:

  1. 工业控制电路:PLC模块、变频器、伺服驱动器中的滤波电容,抑制电源纹波,稳定信号传输(应对-20℃~+85℃工业环境)。
  2. 电源模块:AC-DC/DC-DC电源中的高压滤波电容(输出电压100V~200V场景),提升电源效率与稳定性。
  3. 消费电子:变频空调、智能电视等中高端家电的电源部分,满足宽温运行需求(如空调室外机高温环境)。
  4. 通信设备:基站、路由器的辅助电源滤波,适应机房/户外温度变化。
  5. 车载电子(可选):若符合AEC-Q200车规标准(需核对PSA datasheet),可用于车载电源、传感器电路等场景。

五、品牌与可靠性保障

PSA(信昌电陶)是国内MLCC领域主流制造商,专注陶瓷电容研发10余年,FS46X105K251EFG的可靠性保障包括:

  1. 工艺优势:多层陶瓷叠层技术,电极与介质层结合紧密,无分层、开裂缺陷,提升长期使用寿命。
  2. 标准测试:通过IEC 60384-1国际标准测试(温度循环1000次、湿度试验1000h、焊接热冲击等),满足商用级要求。
  3. 质量管控:批量产品100%初测容值/电压,抽样检测温度特性与ESR,确保一致性符合行业标准。

六、选型与注意事项

  1. 电压降额:实际工作电压≤200V DC,避免过压导致容值衰减或击穿。
  2. 温度范围:工作环境温度不超过125℃,否则容值变化可能超出规格。
  3. 焊盘匹配:PCB焊盘建议尺寸为长5.05.5mm、宽6.87.2mm,确保焊接可靠性。
  4. 替代选型:
    • 更高精度(±5%):选同系列“J”标识型号(如FS46X105J251EFG);
    • 更高电压:考虑FS46系列310V(311)或400V(401)型号;
    • 更小封装:需核对PSA产品目录是否有同参数小封装(如1210)。

该型号凭借中高压、宽温区的性能优势,成为工业、消费电子等领域的实用型高压MLCC选择。

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.
