RL60-050 产品概述

RL60-050 是 RUILON(瑞隆源)推出的一款 60V 500mA 插件自恢复过流保护元件(聚合物正温度系数自恢复保险丝,PPTC)。该器件针对需要重复过流保护且要求快速恢复的电路设计,兼顾小体积与可靠保护性能,适用于各类消费电子、通讯及工业控制场景的输入防护与短路保护。

一、主要电气参数

  • 耐压(Vmax):60 V
  • 最大电流(Imax):40 A(短时极限,通过能力)
  • 保持电流(Ihold):0.5 A(500 mA)
  • 跳闸电流(Itrip):1.0 A
  • 标称功耗(Pd):800 mW
  • 初始态电阻(Rmin):0.4 Ω(400 mΩ)
  • 跳断后最大电阻(R1max):1.2 Ω
  • 动作时间:在标称跳闸电流下约 4 s
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 外形尺寸:长度 7.9 mm
  • 封装形式:插件(引脚式)

二、产品特性与优势

  • 重置型保护:过流后自动恢复,无需更换,降低维护成本。
  • 体积小巧:7.9 mm 长度适合紧凑电路板布局,方便插件安装。
  • 宽电压耐受:最高可承受 60V,适配较高电压系统的输入保护需求。
  • 快速响应:在 1A 水平特性下典型动作时间约 4 秒,能有效限制短路能量。
  • 宽温度适应:-40~+85 ℃ 可在多种环境中可靠工作。

三、典型应用场景

  • 电源输入防护(适配器、开关电源前端)
  • USB、串口等接口过流保护
  • 通信设备与路由器的短路保护
  • 工业控制板和仪器的模块级保护
  • 小功率电池管理与充电电路(注意额定与热环境匹配)

四、选型与使用建议

  • 正常工作电流应低于 Ihold,通常建议在 Ihold 的 70%~90% 范围内运行以保证稳定性与寿命。
  • 设计时应确保短时浪涌电流不会长期超过 Imax,否则可能损坏器件。
  • 若电路存在频繁且持续的高电流脉冲,应评估热累积与重复动作对器件的影响,必要时选用更大规格。
  • 当需要更快动作时间或更低初始电阻时,可考虑同系列不同规格产品。

五、安装与注意事项

  • 插件封装建议垂直或水平固定,焊接时避免对本体施加过大机械应力。
  • 波峰/回流焊接注意焊接温度与时间控制,避免超过器件耐受的热循环(参考供应商焊接说明)。
  • 存储与使用环境避免长时间高温、高湿及强腐蚀性气氛,以免影响可靠性和泄漏电阻。
  • 在布局上建议将器件靠近被保护电源入口处放置,以缩短故障路径与减少寄生电阻影响。

六、可靠性与检测

  • 建议在设计验证阶段进行过流动作测试、热稳定性测试与环境循环(高低温、湿热)测试,确认在实际工况下的动作点与恢复特性。
  • 对于关键系统,推荐做多次重复动作寿命测试,观察 R1max 与恢复时间的变化趋势,确保长期一致性。

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
