B72210S0500K101 产品概述

一、产品简介

B72210S0500K101 为 TDK 出品的径向插件金属氧化物压敏电阻(MOV),设计用于中低压直流/交流电路的浪涌抑制。标称压敏电压82V(典型测量点),钳位电压约135V,适配50VAC / 65VDC 的工作电压环境,能够在瞬态过电压时以最快速度导通并吸收能量,保护后端元器件免受冲击。

二、主要性能参数

  • 压敏电压(Vn):82V(典型)
  • 钳位电压(Vclamp):约135V
  • 允许工作电压:DC 65V;AC 50V
  • 峰值浪涌电流(8/20μs):2.5kA
  • 能量吸收能力:8.4J(单次条件下)
  • 静态电容:950pF @1kHz
  • 最大耗散功率:400mW
  • 引脚间距:7.5mm(径向插件)
  • 封装形式:Thru‑Hole Radial,插件安装

三、典型应用场景

  • 直流供电系统的输入端防护(如电源适配器、蓄电池管理)
  • 交流/直流混合的工控电源、防雷模块
  • 消费电子与白色家电的接口过压保护
  • 电机驱动与逆变器的局部浪涌吸收
  • 与保险/限流器配合构成级联保护电路

四、选型与设计建议

  • 压敏电压对比工作电压:82V 的标称压敏电压适合最大65VDC工况,但应避免MOV在常态下长期承受接近触发点的电压,以免加速老化。
  • 能量与浪涌次数:8.4J/2.5kA 适用于单次或间歇性较大浪涌,若预期多次高能冲击,建议并联多个器件或选择更高能量等级产品。
  • 电容考虑:950pF 的静态电容对高频信号或精密测量电路可能产生影响,敏感电路应评估并必要时隔离或选用低电容保护元件。
  • PCB 布局:将器件靠近入口端或易受冲击的节点,焊点短且牢固;保持良好散热路径以利于能量散失。
  • 配套保护:在严重过压场景下,建议与熔断器、放电管、TVS 等配合使用,实现分级保护。

五、使用与可靠性注意事项

  • 避免长期在额定工作电压附近工作;长期承受高应力会导致压敏电阻特性漂移与寿命缩短。
  • 多次大电流冲击后器件性能会衰减,应在设计中留有检查和更换维护策略。
  • 安装时遵循制造商的焊接温度与时间规范,防止热应力损伤内芯结构。
  • 详细环境温度、浪涌曲线及老化特性请参阅 TDK 官方数据手册,以获得正确定义的使用边界与测试条件。

总结:B72210S0500K101 以其82V 压敏特性、2.5kA 峰值浪涌能力与插件封装,适合用于中低压输入端的可靠浪涌抑制。在选型时需综合评估工作电压裕量、能量需求与电容影响,并遵循正确的安装与维护规范以保证长期可靠性。

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
