10D561K 产品概述

一、基本参数概述

10D561K 为 RUILON(瑞隆源)品牌的插件型压敏电阻(MOV),面向中高能量浪涌抑制场合。主要电气参数如下:压敏电压(Varistor Voltage)504V ~ 616V;钳位电压(Clamping Voltage)920V(峰值浪涌电流2.5kA 下);峰值浪涌电流 2.5kA;能量吸收能力 42.3J;静态电容 180pF(1kHz);工作电压 DC 460V / AC 350V。封装为插件式,针距 P = 7.5mm,便于通孔焊接或波峰焊装配。

二、主要特性

  • 高能量吸收:42.3J 能量等级,可承受 kA 级短时浪涌脉冲,适合工业电网及电源侧抗浪涌保护。
  • 低钳位电压:在 2.5kA 冲击下钳位电压约 920V,有利于限制过电压对下游器件的应力。
  • 适中静态电容:180pF(1kHz)对高频信号影响有限,适合要求不高的电源和控制线路。
  • 插件封装:P=7.5mm 的通孔插件结构,安装可靠,适合维修与替换。

三、典型应用场景

  • 工业变频器、伺服驱动器及马达驱动的直流母线过压保护;
  • UPS、电源模块、开关电源的输入侧浪涌吸收;
  • 机柜供电与电力电子系统中对雷击/开关冲击的抑制;
  • 需要中等电容且能承受高能冲击的场合。

四、选型与使用注意事项

  • 工作电压匹配:DC 460V / AC 350V 为长期允许的连续电压,选型时应保证电路工作电压不超过该值。若系统有反复或持续过压,应选择额定更高的型号或并用保护电路。
  • 浪涌规范:钳位电压通常在规定浪涌波形(如 8/20µs)下测得,实际场合请按系统可能出现的浪涌电流评估是否足够。
  • 布局要求:尽量缩短引线与焊盘走线,避免长导线产生串联感抗,影响钳位效率。
  • 并联/并用:多只压敏电阻并联时需注意电流分配不均导致的早期失效,应配合限流元件或采用并联电阻器进行均流设计。

五、封装与机械信息

插件式(通孔)封装,针距 P = 7.5mm,厚实体积便于散热和机械固定。适合波峰焊或手工焊接,便于后期更换维护。安装时应保证通风和必要的绝缘间隙。

六、存储与安全提示

  • 存放在干燥、洁净环境,避免潮湿与腐蚀性气体;
  • 长期承受接近额定工作电压会降低寿命,推荐在允许范围内留有余量;
  • 在可能出现持续故障或重复大能量冲击的系统中,应配合热熔断器或监测电路,防止压敏电阻自发热失效。

总结:10D561K 提供了 2.5kA 峰值浪涌能力及 42.3J 的能量吸收水平,适用于中高能量防护场合,插件封装便于维护与替换。选用时请结合系统实际连续电压、浪涌波形和安装条件进行详细评估。

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
