RL30-500 产品概述

一、产品简介

RL30-500 是 RUILON(瑞隆源)推出的一款插件式自恢复熔断器(PPTC),额定耐压 30V,保持电流 5A。该器件采用自恢复聚合物热敏材料,当电路发生过流或短路时通过增大自身阻值限制电流,故障消除后可自动恢复到低阻态,适用于对重复保护和免维护要求较高的直流电源线路保护。

二、主要技术参数

  • 耐压(Vmax):30V
  • 最大电流(Imax):40A(短时冲击能力)
  • 保持电流(Ihold):5A(长期不致跳闸的最大工作电流)
  • 跳闸电流(Itrip):10A(在规定时间内触发保护)
  • 消耗功率(Pd):3W(触发或工作时的最大允许功率)
  • 初始态阻值(Rmin):10 mΩ(典型低阻态)
  • 跳断后阻值(R1max):80 mΩ(高阻态限制电流)
  • 动作时间:14.5 s(至触发的参考时间)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 外形长度:17.7 mm
  • 封装方式:插件,间距 P = 10.2 mm
  • 型号与品牌:RL30-500,RUILON(瑞隆源)

三、产品特性与优势

  • 自恢复功能:过流后自动限流并在故障排除后恢复至低阻态,减少更换频次、降低维护成本。
  • 低初始阻值:Rmin≈10 mΩ,常态下对电路压降与发热影响小,适合对效率敏感的电源线路。
  • 良好冲击承受能力:可承受短时高达 40A 的冲击电流,适应电机启动、充电器等场合的瞬态浪涌。
  • 宽工作温度:-40~+85 ℃,适用于工业、电力及户外环境的温度范围。
  • 插件封装:方便手工或波峰/选择性焊接安装,维修替换便捷;P=10.2mm 兼容常规插座布局。

四、典型应用场景

  • 电池管理与保护:便携电源、锂电池组短路/过流保护(适用于 12V/24V 系统)。
  • 电源模块与适配器:DC 输出线路过流防护与重复保护。
  • 通信与网络设备:板端保护、端口过流限制、模块化电源安全保障。
  • 工业控制与仪表:电机驱动前端、传感器供电、继电器线圈保护等需要可恢复保护的场合。

五、安装与使用建议

  • 安装位置:建议靠近电源输入端或被保护负载的靠近分支点处,以快速切断过流源。
  • 散热考虑:尽量避免将 RL30-500 与高热源紧密贴合;在高环境温度下需考虑功率和动作时间变化并适当留空隙。
  • 选择与匹配:工作电流应低于 Ihold(5A),如存在持续高浪涌或接近保护点的长期负载,应选用额定保持电流更高的型号或并联方案(并联需谨慎,参考厂方指导)。
  • 测试验证:在设计阶段对启动浪涌、工作温度与阻值上升进行实际测量,确认 Pd(3W)及动作时间(14.5s)在目标工况下满足要求。
  • 安全提示:PPTC 属于自恢复保护元件,不能替代传统一次熔丝在需要单次断开(不可恢复)或满足特定安规要求的场合。

六、封装与机械信息

  • 尺寸与安装:器件长度 17.7 mm,插件式引脚间距 10.2 mm,适配常见 PCB 插孔或立式插座。
  • 机械可靠性:插件形式便于反复拔插,但建议在震动较大的环境中采取固定或加固措施以避免接触不良。

七、选型注意事项

  • 确认工作电压不超过 30V;若系统电压更高,应选耐压更高的型号。
  • 对于频繁接近触发阈值的应用,建议留有裕量(工作电流低于 Ihold 的 70–80%)。
  • 若需要满足特定认证或安规要求,请向供应商索取相关测试与合格证书。

RL30-500 以自恢复、安全、易维护为主要卖点,适合需要重复过流保护的中低压直流系统。设计时结合具体工作电流、环境温度与浪涌特性进行验证,可获得稳定可靠的保护效果。若需更详细的电气特性曲线或封装图纸,可联系 RUILON 或授权代理获取型号 Datasheet。

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
