10D680K 产品概述

一、产品简介

10D680K 是 RUILON(瑞隆源)推出的一款插件式压敏电阻(MOV),适用于中低压直流和交流系统的过压浪涌保护。器件采用盘形陶瓷压敏芯片插件封装,型号标识为 VAR_D12.5X5.6MM_TM,间距 P=7.5mm,便于通孔安装与快速替换。该器件响应迅速,可在瞬态过压事件中吸收能量并将电压钳位在安全范围内,保护后端电路免受冲击损害。

二、主要技术参数

  • 压敏电压 (Varistor Voltage): 61V ~ 75V(典型标称 75V)
  • 钳位电压 (Clamping Voltage VC): 135V(在规定浪涌条件下测得)
  • 工作电压(DC): 56V(连续工作推荐值)
  • 工作电压(AC): 40V(连续工作推荐值)
  • 峰值浪涌电流 (Ipk): 500A
  • 能量吸收: 6.1J(厂商测试条件下标称值)
  • 静态电容: 2.5nF @ 1kHz
  • 静态功耗/漏电相关指标: 50mW(典型静态条件下)

三、结构与封装

器件为通孔插件式压敏电阻,盘形直径/厚度规格约为 12.5mm × 5.6mm(VAR_D12.5X5.6MM),引脚间距 P=7.5mm,便于标准通孔波峰或手工焊接安装。插件封装使现场更换维护方便,适合电源模块、仪器仪表等需要可更换保护元件的场合。

四、典型应用场景

  • 开关电源输入端与直流母线的浪涌抑制
  • 电池管理、直流供电系统(额定 DC 56V 左右)的过压保护
  • 工业控制设备、继电器驱动电路及逆变器输入保护
  • 家电与通信设备的电源端防护(须根据信号对电容敏感度评估)

五、选型与使用建议

  • 选型时保证压敏电压高于正常工作电压的安全裕量:本器件适用于连续工作电压不超过 DC56V / AC40V 的系统。
  • 对于必须满足较严格钳位电压的场合,参考厂商给出的 VC 与具体浪涌波形、峰值电流对应曲线,确认在指定 Ipk 下的钳位表现。
  • 若用于高速信号或对电容敏感的线路,注意 2.5nF 的静态电容可能影响信号质量,应评估是否合适或采用更低电容方案。
  • 并联多个器件提高能量吸收能力或分散冲击,但需考虑布局与等效阻抗匹配。

六、典型电路与布局要点

  • 压敏电阻一般并联接入被保护线路(跨电源正负极或相线与中性线之间),靠近需要保护的器件放置以缩短回路引线,减少寄生电感。
  • 与熔断器、限流电阻、气体放电管等协同使用可获得更好的浪涌处理能力和可维护性。
  • 焊接时避免长引脚和大回路,采用短而粗的走线以降低感抗和热应力集中。

七、可靠性与注意事项

  • 压敏电阻在承受多次大幅浪涌后会出现特性漂移和能量衰减,应考虑可靠性冗余或定期更换策略。
  • 避免长期在接近最大连续工作电压下运行,以免加速老化。
  • 储存与使用环境应避免潮湿、腐蚀性气体及强机械振动,插件式器件在装配时注意焊接热影响与机械应力。

八、包装与订购信息

  • 品牌:RUILON(瑞隆源)
  • 封装形式:插件 / 通孔,P=7.5mm,VAR_D12.5X5.6MM 尺寸规格
  • 型号示例:10D680K(请以供应商出货单与检验数据为准)
  • 订购时建议索取完整 Datasheet 与浪涌测试曲线(VC vs I、能量吸收条件)以便在具体应用中评估性能并确认兼容性。

如需基于具体浪涌波形(如 8/20μs、10/1000μs 等)进行更详细的选型计算或获得器件的测试曲线与可靠性报告,可提供应用工况,我将协助完成评估与建议。

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
