10D471K 产品概述

一、产品简介

RUILON(瑞隆源)10D471K 为插件式压敏电阻(MOV),用于抑制过电压瞬变与浪涌冲击。该型号设计用于交流/直流供电系统的输入端浪涌保护,具有高能量吸收能力与较低夹位电压,适用于工业电源、开关电源、配电箱及浪涌防护模块等场合。封装为插件,针距P=7.5mm,便于通孔安装与更换维护。

二、主要电气参数

  • 压敏电压(Varistor Voltage):423V ~ 517V
  • 钳位电压(Clamping Voltage,工作时典型夹位):775V
  • 工作电压(DC):385V
  • 工作电压(AC):300V
  • 峰值浪涌电流(Ipeak):2.5kA
  • 能量吸收(Energy):42.3J
  • 静态电容(Capacitance):190pF @1kHz
  • 静态功率(Maximum Continuous Power Dissipation):400mW

三、主要特性与优势

  • 高能量吸收:42.3J 能量能力,能承受较大幅度的浪涌事件,提高设备抗冲击能力。
  • 高浪涌电流承载:单次峰值可达2.5kA,适合遭受强烈瞬态过电压的场合。
  • 有效钳位:775V 的钳位电压在保护线路时能有效限制过电压幅度,减少被保护设备的应力。
  • 通孔插件:P=7.5mm 的插件形式便于手工焊接、维修更换及高可靠性机械固定。
  • 低至中等电容:190pF 对高速信号链影响有限,但在非常敏感的信号线应用需注意寄生影响。
  • 稳定的持续功率承受:400mW 允许器件在正常工作下承受一定直流/交流偏置功率。

四、典型应用场景

  • 工业与民用电源输入端浪涌保护(如配电箱、工业控制柜)。
  • 开关电源(SMPS)初级侧防护。
  • 家用大型电器与商用设备的过压保护。
  • 浪涌保护器(SPD)模块中的主保护元件。

五、安装与使用注意事项

  • 布局:压敏电阻应尽量靠近被保护的输入端或接口,缩短引线及回流路径以提高保护效果。
  • 并联/串联:若需更高能量或更低钳位,可考虑并联或串联多只器件,但要注意均流与电压分配问题。
  • 温度与散热:长期工作时注意器件发热,尽量留有通风空间,避免高温环境导致老化。
  • 与熔断器配合:建议与适当额定的熔断器或限流元件配合使用,防止在极端短路或持续过压情况下器件损毁引发更大故障。
  • 电容影响:在对信号完整性敏感的电路(如高速通信线)应评估190pF 电容带来的影响,必要时采用更低电容方案或隔离措施。

六、选型建议

  • 若系统直流工作电压接近或超过385V,应选用工作电压高于实际电压余量的型号,确保长期可靠性。
  • 对需要更低钳位的场合,可选择钳位更低规格或增加并联器件,但需评估均流。
  • 如需更高能量或更大浪涌电流承载,请选择更大尺寸或更高等级的器件,并确认封装与安装空间匹配。

七、储存与安全

  • 储存环境避免潮湿、高温及腐蚀性气体,建议相对湿度低于60%、温度在-10℃~40℃范围内。
  • 在装配与检修时避免静电放电直接冲击器件,尽量采用防静电操作规程。
  • 发生大幅度浪涌后建议替换器件;若器件出现裂纹、烧灼或电性能显著下降,应立即更换。

以上为10D471K(RUILON)插件压敏电阻的产品概述与使用建议,供选型与工程应用参考。如需更详细的电气曲线、冲击波形条件或可靠性试验数据,可联系厂商获取完整数据手册。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
