RL30-900 产品概述

RL30-900 是 RUILON(瑞隆源)推出的一款插件式自恢复熔断器(PPTC 类似器件),面向需要短路保护、过流保护和可复位保护的低压直流供电场景。该器件经过校验通过,适用于汽车电子、储能电源、工业控制与消费电子等对高电流保护且需复位功能的应用场景。

一、主要电气参数

  • 额定耐压(Vmax):30 V
  • 最大瞬时电流(Imax):40 A
  • 保持电流(Ihold):9 A(在额定环境下不发生动作)
  • 跳闸电流(Itrip):18 A(典型动作点)
  • 动作时间:20 s(达到跳闸电流时的典型动作时间)
  • 消耗功率(Pd):4.2 W(在动作点附近的功耗参考)
  • 初始态电阻(Rmin):5 mΩ(器件冷态低电阻,压降小)
  • 跳断后电阻(R1max):25 mΩ(动作后复位前的高态电阻上限)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 机械尺寸:长度 25.5 mm
  • 封装形式:插件(through‑hole)
  • 品牌:RUILON(瑞隆源)
  • 描述状态:校验通过

二、关键性能与优势

  • 低初始电阻:Rmin 仅 5 mΩ,器件在正常工作时对电路压降影响小,适合对效率和发热敏感的高电流路径。
  • 明确保护阈值:Ihold=9 A、Itrip=18 A 的配置给出良好的误动作裕量,能在短时突发过流下保护电路同时避免常态负载误断。
  • 可复位设计:在过载消除后器件可自行冷却恢复导通,适合需频繁保护与维护方便的场合,降低维修成本。
  • 宽工作温度:-40 ℃ 到 +85 ℃,适用于车载及室外/工业环境。
  • 插件封装:便于在线维修、替换与手工焊接,适合样机验证、小批量生产或要求换件方便的电路板设计。

三、典型应用场景

  • 汽车电子(12V/24V 总线保护、保险丝替代或补充保护)
  • 电池包与储能系统(电池端过流保护、模块间保护)
  • 电动工具与马达驱动(控制器输入侧、短路保护)
  • LED 驱动与照明系统(电源短路与过流保护)
  • 工业电源与通信设备(分支保护、端口保护)
  • 充电器与适配器(输出保护,防止电缆短路造成损坏)

四、安装与使用注意事项

  • 布局位置:将 RL30-900 放置在被保护回路的靠近电源一侧,保证在故障时能切断故障电流并保护下游元件。
  • 散热与环境:动作时器件会发热,请保证适当通风或远离高热源,避免邻近敏感元器件。长期靠近最高环境温度工作时需考虑动作电流的温度漂移并进行裕量设计。
  • 电流选择与配合:Ihold 与 Itrip 的选择应基于电路最大持续工作电流和可能的短时峰值。RL30-900 适合作为慢速过流保护,不替代需要快速断开的熔断器或断路器(例如直短路保护)。
  • 反复动作:虽然为可复位器件,但频繁或长期在过载状态下工作会影响寿命与特性,建议避免长期重复触发。
  • 焊接建议:插件封装便于手工焊接;具体焊接温度/时间仍建议参考厂家完整数据手册以防器件或绝缘材料受损。
  • 验证测试:在批量使用前,建议在目标温度、负载及真实工况下做实际测量验证动作点与恢复行为。

五、可靠性与采购建议

  • 该器件的工作温度范围与低内阻特性使其在车规级和工业级应用中具有竞争力,但对认证(如 UL、AEC‑Q 等)与批量一致性请向供应商索取最新认证与检测报告。
  • 采购时建议索取样品并在目标系统中完成过流/高温/老化测试,确认动作时间(20 s 为典型值)与跳闸行为满足实际需求。
  • 插件形式便于库存与现场更换,注意选型时确认孔距与固定方式与电路板匹配。

总结:RL30-900 为一款面向中高电流应用的插件式可复位过流保护器件,具有低初始电阻、明确的保持/跳闸电流值与宽温度适应性,适合汽车、储能、工业与消费电子等多种场景。在设计中应结合散热、环境温度及短路保护速度要求进行合理配合与验证。如需更详细的电气曲线、机械图或认证资料,请联系 RUILON(瑞隆源)或其授权分销商获取完整数据手册。

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
