FV42X102K402EFQ 产品概述

一、产品基本信息

FV42X102K402EFQ 为 PSA(信昌电陶)系列高压多层陶瓷贴片电容(MLCC),标称容值 1nF,公差 ±10%,额定直流电压 4kV,介质材料为 X7R,封装形式为 1808。该产品针对需要高工作电压与体积受限场合的滤波、耦合与阻尼等应用而设计。

二、主要电气与材料特性

  • 容值:1nF(标称)
  • 容值公差:±10%
  • 额定电压:4kV DC
  • 介质:X7R(耐温范围广,温度特性相对稳定,典型温区内容值变化有限)
  • 封装:1808 贴片(适配自动贴装与回流焊工艺)

X7R 介质在 -55°C 至 +125°C 范围内表现出良好的温度稳定性,适合多数工业和电力类场合。需注意 MLCC 在高直流偏置下会出现容值下降现象,设计时应考虑有效电容随电压变化的影响。

三、产品优势与适用场景

  • 高耐压:4kV 额定电压适用于高压隔离、直流阻断、HV 电源滤波与脉冲电路。
  • 稳定性好:X7R 介质兼顾体积与温度特性,适合宽温区工作环境。
  • 表面贴装:1808 封装兼容 SMT 生产线,量产装配成本低。

典型应用包括高压开关电源、摄影闪光/点火电路、医疗/工业高压模块、通讯和雷达前端高压偏置电路等。

四、设计与装配建议

  • 回流焊:兼容常规回流焊工艺,装配时请遵循厂方推荐的回流温度曲线以保证可靠性。
  • 电压与偏置:在高压应用中应考虑电压降额与直流偏置导致的容值损失,必要时选择更大容值或并联配置以保证实际电路需求。
  • 机械应力:贴片电容对焊接应力与 PCB 弯曲敏感,布板时避免在元件下方留有槽或在装配后进行弯折,使用适当的焊盘设计和粘着剂可降低裂片风险。
  • 环境与老化:存放与使用环境应避免潮湿、高温和化学腐蚀性气体,长期工作建议进行可靠性评估。

五、选型与采购注意

型号 FV42X102K402EFQ 的命名与封装、耐压、容值和公差紧密相关,批量采购前建议索取并核对厂家详细数据手册(包含温度系数曲线、直流偏置特性、尺寸图与焊接建议)以及实物样品做电气与可靠性验证。

如需进一步的性能曲线(例如容值随温度、电压的变化)或封装尺寸图,我可以协助整理并对比同类替代件,便于在具体应用中做出最优选型。

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
