FV31X103K102ECG 产品概述

一、产品概览

FV31X103K102ECG 为 PSA(信昌电陶)系列贴片多层陶瓷电容(MLCC),标称容量 10nF(103),容差 ±10%(K),额定电压 1kV DC,温度特性 X7R,封装尺寸 1206(3.2 × 1.6 mm)。该器件为通用型高压陶瓷片式电容,面向高压直流滤波、耦合、退耦与能量缓冲等应用场景。

二、电气特性与使用注意

  • 容值:10nF,公差 ±10%(K)。
  • 额定电压:1kV DC,适用于高压电路,但建议根据可靠性需求进行降额设计。
  • 温度特性:X7R(-55°C 至 +125°C,容值随温度变化在 ±15% 范围内)。
  • DC偏压效应:X7R在高电场下存在显著容值降低,工作于接近或接近额定电压时,实际有效容量可能下降,设计时需留有裕量。
  • ESR/ESL:固有等效串联电阻和电感很低,适合高频退耦,但在高能量吸收场合需评估峰值电流能力。

三、机械与封装信息

封装为 1206(英制),外形尺寸约 3.2 × 1.6 mm,厚度随型号略有差异。为贴片式端接结构,适用于自动贴装与回流焊工艺。高压器件对焊点完整性和基板应力敏感,避免焊接后基板弯曲导致介质裂纹。

四、典型应用场景

  • 高压电源与升压转换器中的滤波与旁路;
  • HV 测试设备、示波器、测量传感器的耦合/去耦;
  • 逆变器、光伏、储能系统的直流链路补偿(需评估能量承受能力);
  • 医疗及工业级高压电路(非安全类替代件,安全耦合需使用认证元件)。

五、装配与可靠性建议

  • 采用无铅回流焊工艺,遵循 JEDEC/IPC 建议的温度曲线(峰值约 250–260°C);
  • 对于高压应用,建议适度降额(例如 80% 或按系统可靠性需求),并在 PCB 设计中保持足够爬电距离与爬电路径处理;
  • 避免在装配过程中产生机械应力,必要时采用软垫支撑与合理锡膏量;
  • 关心湿热与偏压下的寿命特性,必要时依据应用做加速应力(THB、温循环、绝缘耐压)验证。

六、选型注意事项

  • 若需严格线性温度系数或低偏压漂移,考虑 NP0/C0G 系列;X7R 适合体积与容量比要求高但容值允许变化的场合;
  • 对于安全隔离或直接接触电网的应用,应使用经过安全认证的安规电容(Y/X 类),X7R MLCC 非安规替代;
  • 评估实际运行电压、纹波电流与瞬态电压,确保电容不会进入临界击穿或介质崩溃状态。

七、质量与测试

PSA 产品通常满足 RoHS/无铅工艺要求,常规出货前会进行外观检查、容量与容差测试、绝缘电阻/漏电流、耐压测试及焊接可靠性评估。用户可按需要求提供相关检验报告与可靠性试验记录。

总结:FV31X103K102ECG 是一款面向高压场景的通用型 10nF X7R MLCC,适用于空间紧凑且需高压承受的滤波与退耦场合。选型时重点关注 DC 偏压导致的容量衰减、焊接与机械应力防护以及是否需要安规认证。

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
