14D561K 产品概述

一、产品简介

14D561K 是瑞隆源(RUILON)推出的一款插件压敏电阻(MOV),用于对电源和设备进行瞬态过电压浪涌抑制。该器件为插件封装,间距 P=7.5mm,安装方便、可靠,适用于工业电源、逆变器、配电装置及其它需要过压保护的直流/交流系统。

二、关键技术参数

  • 钳位电压:920V(浪涌时典型钳位)
  • 能量吸收:84.6J(单位冲击能量)
  • 额定工作电压(DC):460V
  • 额定工作电压(AC):350V
  • 峰值浪涌电流:4.5kA(器件瞬态浪涌能力)
  • 压敏电压范围:504V ~ 616V(标称电压区间)
  • 静态电容:360pF @ 1kHz(对信号线影响需评估)
  • 最大静态功率/耗散:600mW(额定直流/交流下的稳态功耗限制)

三、主要特性与优势

  • 强力能量吸收:84.6J 的瞬态能量能力可有效钳位高能浪涌,保护下游器件。
  • 高钳位与宽压差:920V 钳位保证在高压冲击下仍可保持保护状态,同时压敏电压504–616V的范围提供较好的制造公差。
  • 通用安装:插件式 P=7.5mm 便于插板或穿孔安装,适合维修和替换。
  • 适配高电压系统:460V DC / 350V AC 的工作电压等级适用于中高压直流和工业交流场景。
  • 电容适中:360pF 的静态电容对电源线影响有限,但在高速信号/数据总线上需注意可能造成的信号衰减或失真。

四、典型应用场景

  • 太阳能逆变器与光伏并网侧浪涌保护(DC侧防护)
  • 工业直流母线、储能系统的过压保护
  • 配电柜、电源模块及变频器的输入/输出防浪涌保护
  • 中高压电源设备、开关电源与整流模块的旁路保护

五、选型与使用建议

  • 工作电压裕量:在选用时,保证实际工作电压低于器件额定工作电压并留有裕量,避免长期偏载导致老化。
  • 能量与浪涌次数:若系统可能承受多次高能冲击,应评估器件的累积损耗及是否需要并联/串联多只或使用更大能量等级产品。
  • 温升与散热:在高温或持续脉冲条件下需考虑热管理,避免超过器件的功耗和温度极限。
  • 对信号线影响:如用于信号或通讯线路,需评估360pF 电容对带宽的影响,必要时选择低电容等级的压敏电阻或其它保护方案。
  • 安装与焊接:遵循厂商推荐的安装孔距与固定方式,避免机械应力导致器件裂纹。

六、结论

14D561K(RUILON)为一款适用于中高压直流与交流系统的插件式压敏电阻,具备较高的能量吸收能力和可靠的钳位性能,适合用于工业级浪涌保护场合。在选型和布局时,应结合实际工作电压、可能的浪涌能量及系统对电容敏感性的要求进行综合评估,以保证长期稳定可靠的保护效果。

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
