RL60-135 产品概述
一、产品简介
RL60-135 是瑞隆源（RUILON）推出的一款插件式自恢复熔断器（PTC 聚合物正温度系数器件），用于对过流和短路提供自动限流保护。器件在过载后会迅速升温增阻以限制电流，故障恢复后阻值逐步下降、恢复正常工作，无需更换，适合要求高可靠性与低维护的电子系统。
二、主要参数
- 额定耐压（Vmax）：60 V
- 最大瞬时承受电流（Imax）：40 A
- 保持电流（Ihold）：1.35 A
- 跳闸电流（Itrip）：2.7 A
- 功耗（Pd，触发时）：1.71 W
- 初始阻值（Rmin）：120 mΩ
- 跳断后最高阻值（R1max）：320 mΩ
- 动作时间：9.6 s（在标准测试条件下）
- 工作温度：-40 ℃ ~ +85 ℃
- 封装形式：插件，长度 14.5 mm
- 品牌：RUILON（瑞隆源）
三、性能特点
- 自动复位：过流后器件进入高阻状态限制电流，故障消除后自动冷却回复，避免频繁更换一次性熔丝。
- 响应稳定：在接近 Itrip 时能在约 9.6 秒内动作，能有效保护下游电路元件。
- 紧凑可靠：插件封装、14.5 mm 长度，便于 PCB 安装与维护。
- 宽温工作：-40°C 到 +85°C 的工作范围，适应较宽环境温度变化。
- 高浪涌承受能力：能承受短时高达 40 A 的冲击电流，适用于有启动浪涌的负载场景。
四、典型应用
- 通信与网络设备电源保护（不超过 60 V 的输入）
- 工业控制、传感器和仪表的过流保护
- 电池管理与便携设备电源线路保护
- LED 驱动、电机驱动的短路/过流保护（需按实际浪涌与热条件评估）
五、选型与使用注意事项
- 选型原则：将 Ihold 设定略高于最大持续工作电流，保证正常工作不触发；Itrip 要高于短时工况但低于允许的危险电流。
- 热管理：器件动作与恢复与周围散热条件密切相关，高环境温度会降低动作门限并延长恢复时间，应留有充分散热空间。
- 不作主断路器：自恢复熔断器为保护元件，不建议作为隔离开关或安全主断开装置。
- 测试验证：建议在目标系统中进行实际浪涌与热循环测试，确认动作时间与复位性能满足需求。
- PCB 安装：插件封装便于插装与更换，布局时注意周边热源与导热路径，避免误动作或迟滞。
六、常见问题
- Q：可否替代一次性熔丝？
A：在需自动恢复与低维护场景可替代，但在满足认证与安全规则要求（如需独立断开功能）时应谨慎；一次性熔丝仍适用于单次故障不可恢复场合。 - Q：长期高温会如何影响性能？
A：高温会降低 Ihold，使动作更容易发生，并可能延长恢复时间，需考虑热降额与实际工况。
RL60-135 以其自动复位、紧凑封装和较高浪涌承受能力，适合需要多次保护且维护不便的电路。选择和布局时结合系统电流、热环境与浪涌特性进行综合评估，可获得可靠的过流保护效果。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
