FV31X331K102ECG 产品概述

一、产品简介

FV31X331K102ECG 为 PSA(信昌电陶)生产的一款高压贴片多层陶瓷电容(MLCC),额定电压 1 kV,标称电容 330 pF,公差 ±10%,介质系统为 X7R,封装 1206(公制约 3.2 × 1.6 mm)。该型号针对需要高耐压、小型化封装且对温度特性有一定要求的电路应用而设计,兼顾体积、可靠性与成本。

二、主要特性

  • 标称电容:330 pF
  • 精度:±10%
  • 额定电压:1000 V DC
  • 介质:X7R(-55 ℃ 至 +125 ℃,典型温度漂移容差范围)
  • 封装:1206(约 3.2 × 1.6 mm 表面积)
  • 封装形式:贴片(SMD/SMT)
  • 适用工艺:表面贴装回流焊接

三、电气与性能要点

  • 温度特性:X7R 介质在工作温度范围内保证较好的容量稳定性,但相对于 NP0/C0G 仍存在较大的温度/偏压依赖性;典型 X7R 在 -55 ℃ 到 +125 ℃ 范围内容值变化可达 ±15%(请以厂方数据为准)。
  • 直流偏压效应:在高电场(接近或等于 1 kV)下,MLCC 的有效电容会明显下降,尤其是小容量与较高介电常数的材料更为明显。实际设计中应通过测量或参照厂方偏压曲线来评估有效容量。
  • 介质损耗与 ESR:MLCC 通常具有较低等效串联电阻(ESR),适用于频率较高的滤波、旁路场合,但在高压脉冲或大纹波电流环境下需评估发热与介质应力。

四、典型应用场景

  • 高压直流电源滤波与旁路(HV DC link decoupling)
  • 高压耦合/隔离电容(如耦合电路、测试/测量设备)
  • 脉冲电路与高压开关电源中的滤波/补偿元件
  • 高频高压场合的阻尼、谐振电路及分压网络(需考虑偏压效应)

五、封装与装配建议

  • 1206 尺寸适合空间受限的中等功率应用,焊盘设计应参考厂家推荐的过孔/焊盘尺寸以降低应力集中。
  • 回流焊接:按组件制造商的回流曲线进行,建议遵循无铅回流工艺规范(厂方典型回流峰值约 245 ℃ 左右,具体以供应商资料为准),避免过长高温暴露以降低裂纹风险。
  • 板上应避免机械压力(如夹具、弯曲等)直接作用于电容体,以防开裂或损伤。

六、存储与可靠性注意

  • 建议以原厂防潮包装保存,拆封后若有湿敏等级要求应按 IPC/JEDEC 标准处理(回流前必要时进行烘烤除湿)。
  • 避免搬运、运输中跌落或弯曲基板引起的应力集中;施加过大的焊接应力或冷却速率过快均可能导致裂纹。
  • 高压应用请进行老化与耐压测试,确认漏电流与击穿裕度满足设计要求。

七、选型与替代

  • 在高电压且需更好稳定性的场合,可考虑选择更大间隙的封装或介质特性更适合的产品;在要求极低温漂时,考虑 NP0/C0G 系列(但通常耐压与容量受限)。
  • 采购时请关注制造批次、可靠性测试报告以及是否含有 RoHS/REACH 合规信息;如需替代件,请根据额定电压、容量、介质和封装同时匹配,并注意 DC 偏压下的实际容量差异。

如需该型号的详细电气特性曲线(温度响应、偏压特性、漏电流/耐压测试数据)或推荐的焊盘尺寸与回流曲线,可提供具体用途与应用环境,我可进一步为您查找并给出针对性的使用与布局建议。

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
