FV31X471K102ECG 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

FV31X471K102ECG是信昌电陶(PSA) 推出的工业级高压贴片多层陶瓷电容(MLCC),专为高压电路设计,兼顾容值稳定性、封装紧凑性与电压耐受能力,是电源、医疗、通信等领域的高性价比基础元件。作为PSA成熟产品线中的常规高压型号,其以X7R介质工艺为核心,平衡了容值密度与温度适应性,适配多数高压应用场景的需求。

二、关键电气性能参数

该产品的核心电气参数明确,支撑高压电路稳定运行:

  1. 容值与精度:标称容值470pF(标识代码“471”,即47×10¹pF),精度等级为±10%(行业“K”档),满足滤波、耦合场景的容值误差要求;
  2. 额定电压:直流额定电压1kV(1000V),具备充足电压裕量,避免高压环境下的击穿风险;
  3. 温度系数:采用X7R介质,工作温度范围-55℃~+125℃,容值随温度变化控制在±15%以内,相比Y5V等介质更稳定。

三、封装与物理特性

产品采用1206封装(英制标识,对应公制尺寸约3.0mm×1.5mm),适配常规SMT生产线:

  • 尺寸参考:长3.0±0.2mm,宽1.5±0.2mm,厚度约0.8±0.1mm(以PSA官方 datasheet 为准);
  • 工艺兼容性:符合IPC标准焊盘设计,兼容无铅回流焊,焊接可靠性高,减少虚焊缺陷;
  • 体积优势:1206小封装内实现470pF/1kV容值,兼顾电路小型化需求。

四、材料与温度稳定性

核心介质为X7R铁电陶瓷,特性决定应用范围:

  • 温度稳定性:覆盖工业级环境(-55℃至+125℃),容值漂移小,避免极端温度下电路波动;
  • 容值密度:铁电陶瓷容值密度高于NP0介质,可在1206封装内实现高压容值,无需增大体积;
  • 损耗控制:1kHz下损耗角正切(tanδ)≤0.015,满足常规高压电路的发热控制要求。

五、典型应用场景

结合高压、稳定特性与紧凑封装,适用于以下场景:

  1. 工业电源:开关电源、DC-DC转换器的高压滤波(PFC后级、母线滤波)、EMI抑制;
  2. 医疗设备:高压发生器、监护仪的高压耦合/旁路电容,满足医疗可靠性要求;
  3. 通信基站:射频功放高压匹配、基站电源滤波;
  4. 测试仪器:高压测试台、示波器探头的高压电容元件;
  5. 照明领域:LED高压驱动电源滤波,适配户外/工业照明高温环境。

六、品牌与可靠性保障

作为PSA成熟产品,具备可靠品质:

  • 品牌背景:PSA专注MLCC研发生产,产品覆盖通用、高压等系列,工业领域应用广泛;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅无镉;
  • 可靠性测试:通过125℃/1000h高温老化、85℃/85%RH湿度循环、10-2000Hz振动测试,满足工业级寿命要求;
  • 安全裕量:1kV额定电压远高于低压MLCC,应对高压脉冲更安全。

该产品以平衡的性能与性价比,成为高压电路设计中的实用选择,适配多种工业及通用场景的电容需求。

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
