20D101K 产品概述 — RUILON(瑞隆源)

一、产品简介

20D101K 为 RUILON(瑞隆源)系列氧化锌金属氧化物压敏电阻(MOV),专为电源口雷击与浪涌过压防护设计。器件在大电流浪涌时能迅速导通,将过电压钳位在安全范围内,保护下游电路免受瞬态能量冲击,适用于各类直流/交流电源输入端的保护。

二、主要参数

  • 压敏电压:90V ~ 110V
  • 钳位电压:165V
  • 工作电压(DC):85V
  • 工作电压(AC):60V
  • 峰值浪涌电流:6.5kA
  • 能量吸收能力:37.5J
  • 静态电容:4.8nF @ 1kHz
  • 静态功率:1W
  • 封装形式:插件(P=10mm)
  • 品牌:RUILON(瑞隆源)

三、性能特点

  • 快速响应:在雷击或开关瞬变期间迅速从高阻态转为低阻态,实现有效电压钳位。
  • 高浪涌承受力:6.5kA 峰值浪涌电流与 37.5J 能量吸收能力,能应对常见工业与民用电网的浪涌事件。
  • 稳定的钳位电压:典型钳位值 165V,可为下游器件提供可靠电压限制。
  • 低静态功耗与适中电容:静态功率 1W,有助于降低自发热;4.8nF 的电容值需在高速或敏感信号设计中予以考虑。

四、典型应用

  • 各类电源口过压保护(直流/交流电源输入)
  • 通信设备、电源适配器、蓄电池管理系统、逆变器的浪涌防护
  • 工业控制、楼宇自控及户外供电模块的雷击浪涌防护

五、安装与使用建议

  • 建议将 MOV 置于电源入口靠近端子处(线端对地或线对线),以缩短环路并最大化保护效果。
  • 对于直流系统,按电源两端并联布局;对于交流系统,根据线路结构选择相对接法(L-N、L-G 或 N-G)。
  • 配合熔断器或限流元件使用:在大电流事件中,熔断器可防止 MOV 持续过热延长寿命并提供次级故障隔离。
  • 在 PCB 布局上保持足够的爬电距离与绝缘,插件封装(P=10mm)便于更换维修。

六、设计和可靠性注意事项

  • MOV 在经历过大能量冲击后可能退化或失效,应在设计中考虑更换策略与故障指示方式。
  • 静态电容 4.8nF 会对高频信号或对称性要求高的电源系统产生影响,必要时评估对滤波与信号完整性的影响。
  • 长期工作在接近或高于额定工作电压下会加速老化,建议在实际工况下适度留有裕量。
  • 环境与温度对性能有影响,严苛环境下需按厂方规格进行温度与潮湿度限制。

七、典型电路与配合措施

  • 标准防护:MOV 并联在电源输入端,输入侧串联熔断器或自恢复保险丝(PTC)以限制持续故障电流。
  • 组合防护:与气体放电管(GDT)、瞬态抑制二极管(TVS)组合使用,可实现更宽频带和更高能量处理能力的分级防护方案。
  • 接地建议:确保良好接地以便浪涌能量通过低阻路径释放,减小对系统其它部分的影响。

八、封装与备件

20D101K 为插件式封装,针距 P = 10mm,便于手工焊接和维修更换。适用于需要现场更换及维护的电源模块与设备。

结语:20D101K(RUILON)凭借较高的浪涌承受能力与稳定钳位特性,是电源口过压防护的可靠选择。在具体应用中,应结合熔断器、接地与分级保护策略,以获得最佳的长期可靠性和安全性。

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
