RL60-250 产品概述

一、产品简介

RL60-250 为 RUILON(瑞隆源)系列插件自恢复熔断器(PPTC),额定耐压 60V,保持电流 2.5A,属于用于过流保护的自恢复式保护元件。器件在过流时通过正温度系数效应显著增加阻值,限制电流并保护下游电路;故障消除并冷却后阻值恢复至接近初始状态,无需更换,便于维护与长期可靠运行。封装为插件式(P = 10.2mm),适合插座或夹持安装,便于更换与检修。

二、主要规格(关键参数)

  • 额定耐压(Vmax):60 V
  • 最大短时耐受电流(Imax):40 A(短时允许值,非长期工作电流)
  • 保持电流(Ihold):2.5 A(常温下器件不动作的最大电流)
  • 跳闸电流(Itrip):5 A(器件进入高阻态的典型电流)
  • 最大功耗(Pd):2.5 W(器件在稳态下的最大允许耗散)
  • 初始态阻值(Rmin):50 mΩ(冷态、未动作时的典型最小电阻)
  • 跳断后阻值(R1max):150 mΩ(动作后的最大阻值)
  • 动作时间:15.6 s(受过流幅值与环境温度影响的典型响应时间)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:插件,针距 P = 10.2 mm
  • 品牌:RUILON(瑞隆源)

三、工作原理与性能特点

  • 自恢复:采用聚合物正温度系数材料(PPTC),在过流或过温情形下材料发热、阻值迅速上升,限制电流后保护电路;故障消除并冷却后阻值恢复到低阻态,设备自动复位。
  • 可重复使用:与一次性熔断器不同,多次过流事件后仍可恢复工作,降低维护成本。
  • 耐脉冲能力:短时可承受较大脉冲电流(Imax 可达 40A),适用于带有启动冲击或突发脉冲电流的设备。
  • 低额外损耗:初始态低阻值(≈50 mΩ)对正常工作时压降与发热影响小。
  • 宽温工作:在-40 ℃ 至 +85 ℃ 环境下仍能保持稳定特性,但高温会降低持流能力并缩短动作时间。

四、典型应用场景

  • 电源模块与DC-DC转换器输入保护(额定电压 ≤ 60V)
  • 电池管理与电池组短路保护(便携设备、UPS、小型电动车外围电路)
  • 通信设备、路由器、ONT、电源适配器的过流保护
  • 工业控制器、仪表、LED 驱动器的过流/短路防护
  • 保险替代方案中需要自动复位功能的场合

五、选型与使用建议

  • 额定选择:推荐将 RL60-250 的常规工作电流控制在 Ihold 以下,最佳留有 20%~30% 的裕量(例如长期工作电流 ≤ 2.0 A)。
  • 考虑环境:高环境温度会降低器件的有效保持电流,若长期在高温工况下使用,应选择更高规格或增设散热措施。
  • 启动浪涌:若电路存在大幅启动电流或反复脉冲,应评估 Imax 能否承受相应脉冲能量,并关注反复动作对寿命的影响。
  • 布局与安装:插件式封装便于更换,安装时确保良好接触与机械固定,避免振动或接触电阻增大。针脚间距 P = 10.2mm,适配标准插座/夹持件。

六、可靠性与注意事项

  • 重复动作可能导致器件性能缓慢退化,应定期检查关键保护点。
  • 自恢复熔断器并非快速熔断器,不能替代在要求极短时间动作的保护元件;对于需要瞬时切断高能短路的场合,应配合熔断丝或断路器使用。
  • 不建议在超过标称耐压(60V)或超过长期功耗限制(Pd)下使用,以免加速老化或损坏。
  • 长期超负荷或频繁触发会增加复位时间并可能升高动作后阻值(不超过 R1max 指定值)。

七、包装与订购信息

  • 型号:RL60-250(RUILON)
  • 封装形式:插件(P = 10.2mm)
  • 应在采购时确认工作电流与环境工况匹配,必要时索取样品或详尽的电气-热试验曲线以验证在目标应用下的动作特性。

如需针对具体电路(含启动浪涌、环境温度、并联配置等)的计算与选型建议,可提供电路参数与使用工况,我将给出更精确的匹配与布置方案。

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.
