RL60-075 产品概述
一、概述与定位
RL60-075 是 RUILON（瑞隆源）推出的一款 0.75A 60V 自恢复型过流保护元件（多为聚合物正温度系数自恢复熔断器，PTC/Polyfuse）。器件采用插件封装，整体长度 10.7mm，适合通过孔安装的印制板或线束串联保护，主要用于中低压直流电源环节及需要可复位保护的电子设备。
二、主要电气参数
- 额定耐压（Vmax）：60V
- 最大持续电流（Imax）：40A（器件极限耐受或短时脉冲能力）
- 保持电流（Ihold）：0.75A（在规定温度与时间下可长期通过而不致动作）
- 跳闸电流（Itrip）：1.5A（在规定条件下开始显著升阻、进入保护态）
- 消耗功率（Pd）：950mW（额定功耗/发热限制）
- 初始态电阻（Rmin）：0.18Ω（180mΩ）
- 跳断后最大电阻（R1max）：0.62Ω（620mΩ）
- 动作时间：6.3s（在指定过流条件下的动作响应，适合慢速过流/持续过载检测）
- 工作温度范围：-40℃ ~ +85℃
三、特性与优势
- 自恢复设计：过流或过温后自动升阻限流，故障消除后自动恢复，减少维护和更换成本。
- 低初始电阻：180mΩ 的低阻值可降低正常工作时的压降和功耗。
- 宽温度适应性：-40℃ 至 +85℃，适用于室内与常温工业环境。
- 插件封装：便于装配、维修与替换，适配手工或波峰/选择性焊接工艺（请遵循厂家焊接规程）。
四、应用场景
- USB/外设、便携设备的输入电源保护
- 开关电源、适配器、充电器的输出及分支保护
- 电池组、备用电源和小功率直流模块的过流限制
- LED 驱动、继电器线圈、传感器模块等需自恢复保护的线路
五、使用与选型建议
- 选型原则：Ihold 应略高于设备正常工作电流，Itrip 应低于可接受的故障电流阈值以实现保护。
- 热余量考虑：Pd 为 950mW，实际线路中注意器件发热与周围散热条件，避免长时间接近功耗上限。
- 对于短路或瞬态极高电流场合（如直接短路），RL60-075 的动作时间较长，必要时请与快速熔断器或限流电路配合使用。
- 安装时避免强烈弯折或机械应力，焊接温度和时间请遵循供应商推荐，防止性能退化。
六、可靠性与注意事项
- 自恢复元件循环次数高，但长期频繁触发会逐步改变恢复后阻值，建议在设计中预留容差。
- 若用于关键安全或需严格电流限制的场合，建议做充分的热试验和寿命评估。
- 请参考 RUILON 提供的详细规格书和过流/温度曲线，以便在具体工况下准确评估性能。
RL60-075 以其自恢复、低阻、插件易装的特点，适合多数中低压直流场景的过流保护，是工程中常用的保险替代方案。若需进一步的曲线数据、封装图或样品测试建议，可联系供应商或索取详细数据手册。

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.
