10D820K 产品概述

一、产品简介

10D820K(品牌:RUILON/瑞隆源)是一款插件式压敏电阻(MOV),专为中低电压浪涌抑制设计。其关键电气参数包括压敏电压(Varistor Voltage)74V~90V、钳位电压135V、直流工作电压65V(DC)、交流工作电压50V(AC)、峰值浪涌电流2.5kA、最大吸收能量7.4J、静态电容2.1nF(1kHz)以及静态功率耗散400mW。该器件通过了校验,适合用于直流或低频电源的浪涌保护和过电压抑制场合。

二、主要特性

  • 有效浪涌抑制:峰值浪涌电流达到2.5kA,单次冲击能量7.4J,能瞬时吸收较大的过电压脉冲。
  • 低钳位电压:典型钳位135V,能在过电压事件中将电压限制在较为安全的水平,保护后级器件。
  • 适配中低压系统:直流工作电压65V、交流工作电压50V,适合48V通信、电源总线及类似应用。
  • 插件封装:便于手工或波峰焊装配,适合维修与替换。
  • 中等静态电容:2.1nF@1kHz,需在对高频信号敏感的场合评估其对信号完整性的影响。
  • 稳定耗散能力:静态功率400mW,可承受一定持续过压工况但仍需遵循使用规范。

三、典型应用场景

  • 通信设备与48V供电系统的端口浪涌保护
  • 工业控制、电源模块与逆变器的输入端浪涌抑制
  • 电池管理与组合电源保护(需注意电池工作电压范围)
  • 电源适配器、直流配电与整流输出端防护

四、选型与布局建议

  • 工作电压裕度:工作电压(DC 65V)应低于压敏电压范围下限,建议预留裕度以避免长期偏置导致寿命降低。
  • 与熔断器配合:在高能量场合建议与熔断器或过流保护器件串联,防止压敏器件在严重过压时持续发热或失效。
  • 板上布局:远离敏感模拟/高频走线,考虑其2.1nF静态电容对信号线的影响;插件安装便于散热和替换,但需保证良好通风散热。
  • 温度与老化:高温、长期反复浪涌会降低器件性能,应遵循厂商热循环与冲击寿命数据。

五、测试与可靠性注意

  • 常规测试:测量漏电流、压敏曲线(V-I)、钳位电压以及在标准冲击(如8/20μs)下的浪涌响应。
  • 寿命评估:关注在经常冲击条件下的能量衰减、压敏电压漂移及破裂风险。
  • 安全使用:避免在持续过压状态下长期工作,必要时增加热熔断保护或冗余设计。

六、总结

10D820K(RUILON)是一款面向中低压保护的插件式压敏电阻,具有2.5kA峰值浪涌能力和135V的钳位水平,适合48V级电源与通信设备的浪涌防护。选型时需兼顾工作电压裕度、静态电容对信号的影响及热管理,配合过流保护能获得更可靠的系统性能。如需在特殊环境或高频信号线中使用,建议与供应商确认更多试验数据与寿命曲线。

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
