RL60-375 产品概述

RL60-375 是 RUILON(瑞隆源)品牌的一款径向自恢复保险丝(Polymeric PTC resettable fuse),面向需要过流保护且希望设备在故障消除后自动恢复工作的电源与负载保护场景。该器件在保护电路安全性与维护方便性之间提供了平衡,适合消费电子、通信、电源模块及电池管理等领域使用。

一、主要参数

  • 耐压 (Vmax):60 V
  • 最大电流 (Imax):40 A
  • 保持电流 (Ihold):3.75 A
  • 跳闸电流 (Itrip):7.5 A
  • 消耗功率 (Pd):3.2 W
  • 初始态阻值 (Rmin):30 mΩ
  • 跳断后阻值 (R1max):100 mΩ
  • 动作时间:24 s(典型或条件相关,详见厂方数据)
  • 长度:28.5 mm
  • 封装:径向(具体引脚间距及外形请参照原厂机械图)

二、产品特性

  • 自恢复能力:过流时电阻大幅上升限流,故障解除后冷却回弹恢复低阻态,免更换。
  • 低初始阻值:30 mΩ 起始阻抗,适用于对压降敏感的电源路径。
  • 高耐受短时大电流:标称 Imax 可达 40 A,适合承受启动冲击与浪涌电流。
  • 体积与安装:径向引出便于通孔安装,长度 28.5 mm,适合 PCB 上电源输入或模块保护位置。

三、典型应用

  • 电源输入保护(开关电源、适配器)
  • 电池组保护与充放电回路
  • DC 电机、继电器线圈、LED 驱动保护
  • 通信设备、路由器、存储设备电源防护

四、选型与注意事项

  • 以 Ihold 与 Itrip 为主:正常工作电流应小于 Ihold(3.75 A),避免长时间处于温升状态;短时浪涌应低于 Imax。
  • 考虑环境温度:PPTC 的保持/跳闸电流通常以 25 ℃ 测得,高温会降低保持电流,需按应用环境做降额。
  • Pd 与热耦合:最大功耗 3.2 W 表示器件在被迫限流时的热能力,实际热分布受 PCB、散热片与周围器件影响。
  • 验证动作时间:24 s 为特定过流条件下的动作时间,请在目标电压/电流下做实际测试以确认行为。

五、测试与可靠性验证

  • 建议做 I-V 曲线、保持/跳闸电流重复测试、温度循环、长期老化及浪涌脉冲试验(峰值与次数)以评估寿命。
  • 测试时记录冷态与热态阻值(Rmin 与 R1max),确认在重复跳闸后阻值变化仍在可接受范围内。

六、安装与储存建议

  • 采用通孔焊接:按厂方推荐的焊接温度与时间进行,避免过高回流温度或长时间高温引起性能退化。
  • 布局注意:远离高温元件并保证必要的散热空间;若用于电池箱体,注意绝缘与防短路。
  • 存储于干燥、常温环境,避免潮湿与强光直射,长期存放前建议参照供应商建议。

七、常见替代与采购建议

  • 若需要更小体积,可考虑 SMD 型自恢复保险丝或更高阻值型号以降低尺寸;若需一次性快速断路,可选用熔断式保险丝。
  • 采购时确认完整的机械图、热特性曲线及认证(如有)并向厂商索要实际测试数据。

注:本文基于提供的基础参数进行概述,器件的动作特性与测试条件(例如温度、测量方法)会影响标称值,最终设计中请以原厂完整数据手册与样品测试结果为准。

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
