FM43X104K631EFG 产品概述

一、产品简介

FM43X104K631EFG 为 PSA(信昌电陶)出品的一款贴片多层陶瓷电容(MLCC),额定电容 100nF,公差 ±10%(K),额定直流电压 630V,介质为 X7R,常用 1812 封装。该系列针对高电压场合设计,结合良好的温度稳定性与体积优势,适合中高压电源滤波、耦合和缓冲等应用。

二、主要参数与特性

  • 容值:100nF(0.1µF)
  • 精度:±10%(K)
  • 额定电压:630V DC
  • 介质:X7R(工作温度范围 -55°C 至 +125°C,温度下容量变化一般可控在 ±15% 范围内)
  • 封装:1812(常见物理尺寸约 4.5mm × 3.2mm,实际尺寸以厂方数据为准)
  • 优点:高耐压、小体积、良好頻率特性、适用于无铅回流焊工艺、抗振动与长期可靠性较高

三、典型应用场景

  • 中高压开关电源滤波与旁路:在高压侧进行去耦、抑制尖峰与噪声
  • 高频脉冲与储能回路:用于脉冲整流、能量释放或吸收场合
  • LED 驱动与电子镇流器:高电压环境下的耦合与滤波
  • 工业电源、仪器仪表及通信设备的高压电路中作为阻尼、旁路元件

四、封装与装配建议

  • 封装:1812 适配常见贴片工艺,建议按 SMT 自动化贴装流程处理
  • 焊接工艺:兼容无铅回流焊,建议遵循 IPC/JEDEC 推荐回流曲线,峰值温度不超过 260°C,峰值时间尽量控制在短时内(如 ≤10s),以避免热应力导致性能退化
  • 储存与处理:避免受潮、避免强机械冲击和弯曲贴片端电极;若为湿敏元件,请按 MSL 要求进行烘烤或及时使用
  • 可靠性注意:高压应用时应考虑电压边际、击穿裕度及焊盘应力,必要时配合阻尼或限流元件使用以提升系统可靠性

五、选型注意事项与替代建议

  • 温度与频率影响:X7R 在高温或低频情况下容量会有一定变化,若电路对容量稳定性要求极高(如精密计时或高精度滤波),建议评估是否需选用 NP0/C0G 等温度系数介质或更大余量的容值
  • 漏电与寿命:高压下注意长期漏电和老化效应,关键场合可要求出具更严格的可靠性测试报告
  • 替代与兼容:市场上有多家厂商提供相同容值/电压/封装的 X7R MLCC,可依据库存与认证选择互换型号;选型时核对尺寸、电压等级、封装及制造商技术规范以保证互换性

产品型号:FM43X104K631EFG(品牌:PSA / 信昌电陶)。如需进一步技术资料(电气等效电路、温度/电压系数曲线、机械图纸或可靠性数据),建议向厂商获取最新数据手册以便做出更精确的设计判定。

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
