RL60-300 产品概述

一、产品简介

RL60-300 是 RUILON(瑞隆源)出品的一款插件式自恢复熔断器(复位式保险丝),额定耐压 60V、额定电流 3A(保持电流 Ihold = 3A),适用于低压直流电路的过流保护与短路限制。器件为插件封装,针距 P = 10.2mm,长度 24.9mm,便于 PCB 插装与维护。

二、主要技术参数

  • 型号:RL60-300(RUILON)
  • 耐压(Vmax):60 V
  • 保持电流(Ihold):3 A
  • 跳闸电流(Itrip):6 A
  • 最大承受电流(Imax):40 A(短时冲击能力)
  • 初始态阻值(Rmin):40 mΩ
  • 跳闸后阻值(R1max):120 mΩ
  • 最大消耗功率(Pd):2.8 W
  • 动作时间(典型):19.8 s(标准测试条件下)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:插件,针距 10.2 mm,长度 24.9 mm

三、性能说明

RL60-300 在正常工作电流低于 Ihold(3A)时保持低阻态(典型初始阻值 40 mΩ),电路电压损耗小,发热量低。当电流上升并超过 Itrip(6A)且持续一定时间,器件进入高阻态(跳闸),阻值可升至最大约 120 mΩ,从而限制通过电流并保护后级电路。动作时间 19.8 s 为典型值,实际跳闸时间会随超载幅度、环境温度和散热条件变化。Imax = 40A 表示器件具有较强的短时冲击承受能力,但不建议长期超过额定范围重复使用。

四、典型应用场景

  • 通信设备与网络设备的直流电源保护
  • 消费类电子(充电器、电源适配器、充电桩外围)
  • 电池组与电源管理模块的短路/过流保护
  • 工业控制与仪表的线路保护(低压直流)
  • 电脑周边与外设接口保护

五、选型与使用建议

  • 连续工作电流应低于 Ihold,为可靠运行建议留出余量(常见建议 20%~30% 余量),避免长期在临界值附近运行。
  • 环境温度升高会降低保持和动作电流能力,设计时应根据最高工作温度做温度修正或留裕量。
  • 对于存在频繁冲击或较大浪涌的场合,应评估 Imax 能否承受及其重复冲击的影响;必要时并联或选用更高规格型号。
  • 确保器件周围有足够散热空间,远离热源,以维持标称特性。
  • 推荐在原型阶段按实际工况进行热、寿命和重复跳闸试验,确认长期稳定性。

六、安装与焊接建议

  • 插件封装,针距 10.2 mm,建议使用合适的通孔插装工艺并提供机械固定,防止震动导致接触不良。
  • 焊接时避免长时间高温加热,遵循常规通孔焊接工艺规范,必要时在焊接后对器件进行功能检验。
  • 安装时注意极性通常无要求,但保持良好接触与电气连接是保证低阻特性的关键。

七、安全与可靠性注意事项

  • 自恢复熔断器可在故障清除后自动恢复导通,但多次跳闸后器件特性(阻值、动作电流)可能发生漂移,应在关键应用考虑定期检测或更换策略。
  • 不可用于替代瞬时熔丝以满足高能量断路的场合;对于需要明确一次性熔断保障的安全电路,应采用一次性熔丝或配套保护器件。
  • 在高湿、腐蚀性气氛或强振动环境下,请与供应商确认长期可靠性和封装适应性。

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
