10D681K(RUILON 瑞隆源)产品概述

一、产品概况

10D681K 为 RUILON(瑞隆源)品牌的插件型压敏电阻(MOV),封装为插件形式,端距 P=7.5mm,属于中功率浪涌保护器件。该器件专为高压直流与高压交流系统的过电压吸收与抑制设计,具有较高的浪涌能量吸收能力与良好的响应速度,可用于直流母线、逆变器前端与工业电源防护。

二、主要电气参数

  • 压敏电压(V1mA):612V ~ 748V(典型型号 681 对应约 680V 等级,K 表示公差 ±10%)
  • 钳位电压(Ipp=2.5kA):约 1.12kV(1120V)
  • 工作电压 DC:560V
  • 工作电压 AC(有效值):420V
  • 峰值浪涌电流 Ipp:2.5kA
  • 能量吸收(单次,IEC 测试工况):42.3J
  • 静态电容:140pF @ 1kHz
  • 最大直流泄漏功率(功耗):400mW

三、性能特点

  • 高能量吸收:单次吸能 42.3J,适合中等能量浪涌抑制。
  • 有效钳位:在大电流冲击下钳位电压约 1.12kV,保护下游元件免受瞬态过压。
  • 低静态电容(140pF):对高速信号路径或敏感模拟电路干扰较小。
  • 插件封装、安装方便,适合维修与更换。

四、典型应用场景

  • 直流母线保护(例如光伏逆变器、储能变换器)
  • 工业电源与驱动系统的输入端防护
  • 高压充电设备、EV 充电桩前端浪涌抑制
  • 需要中等能量抑制且便于更换的设备场合

五、安装与使用注意事项

  • 保持器件工作电压低于标称工作电压(直流 560V,交流 420V)并保留裕量,以避免长期加速老化。
  • 插件焊接时避免过热、缩短加热时间并保证良好导热路径;焊后应检查引脚间距与绝缘间隙。
  • 在高频或高精度模拟回路中注意其 140pF 电容带来的影响,必要时增加隔离或滤波设计。

六、选型与配合建议

  • 如需更低钳位或更高能量,应考虑并联多只或选用更大规格 MOV 与气体放电管、TVS 二极管配合形成多级保护。
  • 在可能发生持续高电压的应用,应评估热功耗与老化速率,必要时在电路中加入限流元件或熔断器以保证安全失效模式。

七、可靠性与测试

  • 推荐在设计验证阶段进行实际浪涌试验(符合 IEC 标准)以验证钳位行为与吸能能力。
  • 长期工作在靠近最大允许功耗下会加速参数漂移,应在可靠性试验中关注漏电流与压敏电压变化。

八、存储与维护

  • 干燥、常温环境存放,避免潮湿与强光照射。
  • 定期检查设备运行环境与外观,发现明显裂纹或碳化应立即更换。

10D681K 以其较高的吸能能力、明确的工作电压范围和插件封装,在工业与高压直流保护中是可靠且易维护的选择。根据具体系统的电压等级和浪涌特性进行合理配套与安全冗余设计,可显著提升系统的抗干扰与寿命表现。

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
