14D431K 产品概述

一、产品简介

14D431K 是 RUILON(瑞隆源)推出的一款插件型金属氧化物压敏电阻(MOV),专为电力系统与电子设备的过电压保护设计。器件经过校验通过,性能稳定,适用于对浪涌吸收和瞬态过电压抑制有较高要求的场合,为系统提供可靠的瞬态能量吸收能力与稳健的长期保护。

二、主要参数

  • 品牌:RUILON(瑞隆源)
  • 封装:插件(Disc / Through-hole)
  • 压敏电压:387 V ~ 473 V
  • 钳位电压:710 V(峰值钳位水平)
  • 工作电压(DC):350 V
  • 工作电压(AC):275 V
  • 峰值浪涌电流:4.5 kA
  • 能量吸收:77.4 J
  • 静态电容:440 pF @ 1 kHz
  • 最大持续功率(静态功耗):600 mW
  • 描述验证:校验通过

三、性能特点

  • 抗浪涌能力强:峰值浪涌电流达4.5 kA,能在短时强脉冲下吸收大量能量(额定能量77.4 J),有效保护下游器件免受瞬态过电压损害。
  • 钳位电压可控:在过电压事件中将电压钳制在约710 V,减少高压尖峰对电路的冲击。
  • 适应市电与直流系统:275 VAC / 350 VDC 的额定工作电压使其适合工业、民用电源以及部分直流供电场景。
  • 高频特性:静态电容约440 pF(1 kHz),需在对高频信号敏感的电路中考虑其影响(如滤波、电信高速链路等)。
  • 稳态损耗低:静态功率600 mW,适用于常态下的稳压/待机环境。

四、典型应用

  • 交流配电与主电源的浪涌保护(如交流输入模块、配电箱、防雷一级保护)
  • 开关电源、适配器、逆变器的输入端过压防护
  • LED 驱动、电机驱动器、家电与工业控制设备的瞬态保护
  • 通信设备与信号接口(在考虑容性影响的前提下)

五、安装与使用建议

  • 建议在设备设计中将 MOV 安装于靠近电源入端或需要保护的关键节点位置,以缩短保护回路路径。
  • 常态工作电压应低于器件标称工作电压,避免长期接近极限值运行以延长寿命。
  • 插件焊接时避免长时间高温暴露,遵循厂商推荐的焊接工艺与加热曲线,防止热应力或内部结构损伤。
  • 由于存在静态电容,若用于高频或精密模拟线路,应评估对信号完整性的影响并酌情隔离或滤波。

六、可靠性与测试

  • 器件通过出厂校验,常见浪涌测试和钳位测试可按行业标准波形(如 8/20 μs)进行验证以确认实测峰值电流与钳位电压表现。
  • 在实际应用中建议结合熔断器、PTC 或其他过流保护元件协同使用,提升系统整体可靠性。

七、采购与技术支持

RUILON(瑞隆源)提供批量供货与技术咨询服务,购买时请确认完整规格表与样品测试需求。对于特定应用场景(如特殊浪涌波形、高湿或高温环境)建议联系厂商获取更详细的环境适应性与寿命评估数据。

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
