561KD07 产品概述

一、概述与主要参数

561KD07 为 Brightking(台湾君耀)生产的插装型金属氧化物压敏电阻(MOV),外径约7 mm,脚距 P = 5 mm,适用于中高压直流/交流电路的浪涌与过压保护。主要电气参数如下:

  • 压敏电压(Vnom):560 V(标称)
  • 钳位电压(Vclamp):925 V(在指定冲击电流下的典型钳位值)
  • 工作电压(直流):460 V DC
  • 工作电压(交流):350 V AC
  • 峰值浪涌电流(Ipp):1.75 kA(脉冲冲击能力,典型8/20 μs 波形请参照数据手册)
  • 吸收能量:49 J(单次冲击能量能力,依冲击波形不同有所区别)
  • 静态电容:90 pF @ 1 kHz(对高频信号有影响)
  • 最大持续功率耗散:250 mW(Ta=25°C,持续功率限制)

二、性能特点

  1. 高压等级与大电流吸收能力:560 V 的标称压敏电压配合高达1.75 kA 的峰值冲击能力,可应对工业电源、交换装置及中高压直流系统的瞬态浪涌。
  2. 有效能量处理:49 J 的能量吸收能力使其在面对单次强冲击时具有较好的保护余量。
  3. 低电容特性:约90 pF 的静态电容在保护电源线同时,对高速信号和部分滤波电路影响较小,适合要求一定带宽的系统。
  4. 插装封装易于更换:P = 5 mm 的插件引脚便于维修更换与手工焊接,适合电源模组与维修友好设计。
  5. 稳定的钳位行为:在额定冲击下反应迅速,能将过压限制在设备可承受范围,降低下游器件损坏风险。

三、典型应用场景

  • 开关电源(SMPS)输入侧过压与浪涌保护
  • 电力电子设备直流母线防护(如中小型逆变器、变频器)
  • 太阳能逆变器与光伏电站直流侧防护
  • 工业控制与配电柜的浪涌缓解
  • 电源浪涌保护器(SPD)、电源滤波模组与电源适配器

四、使用建议与注意事项

  1. 工作电压限制:长期工作时不得超过标称工作电压(460 V DC / 350 V AC),否则会加速老化并降低寿命。
  2. 温度与功率耗散:250 mW 为室温下的持续功率耗散上限,安装时需考虑周围环境温度与散热条件,必要时留出足够的热阻余量及通风。
  3. 冲击波形与重复冲击:标注的能量与浪涌电流基于特定测试波形,实际应用中应参考厂商完整数据手册并根据冲击重复次数进行器件选型或并联/并置保护方案。
  4. 电容影响:90 pF 的静态电容在高频或带通信号线中可能引入寄生耦合,敏感信号通道应评估其影响并适当隔离或使用低电容替代方案。
  5. PCB 布局:压敏电阻应靠近被保护端口或电源入口放置,保持短且宽的铜箔连接,避免长导线引起额外电感和电压尖峰。焊接时注意温度曲线以防陶瓷或接点损伤。

五、封装与可靠性建议

561KD07 为插件式元件,机械稳定性适合频繁维修场景。为保证长期可靠性,推荐:

  • 在高脉冲场景下实施周期性检测或更换策略;
  • 与温度敏感器件隔离,避免长期高温加速失效;
  • 在并联使用时匹配同批次器件,确保等分冲击能量;
  • 设计保护回路(如熔断或限流器件),以减少压敏电阻在极端条件下的过热风险。

总结:561KD07 以其560 V 的压敏等级、强劲的冲击吸收能力与插件式封装,适合中高压电源与工业应用的浪涌保护需求。具体选型及安装细节建议参照 Brightking 官方数据手册并根据实际电源条件进行仿真验证。

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
