RL250-080 产品概述
RL250-080 是 RUILON（瑞隆源）推出的一款插件式自恢复过流保护器件，适用于对电路进行可复位、重复保护的场合。该器件经校验通过，可在异常过流时迅速限制电流并在故障消除后恢复初始状态，具有安装便捷、维护成本低的优点，适配多类消费电子、通信设备和工业控制系统。
一、主要参数
- 耐压（Vmax）：250 V
- 最大电流（Imax）：3 A
- 保持电流（Ihold）：80 mA
- 跳闸电流（Itrip）：160 mA
- 消耗功率（Pd）：1 W
- 初始态阻值（Rmin）：12 Ω
- 跳断后阻值（R1max）：33 Ω
- 动作时间：500 ms
- 封装形式：插件（through-hole）
- 品牌：RUILON（瑞隆源）
- 质量状态：校验通过
二、产品特点
- 精确的过流门限：Ihold = 80 mA 与 Itrip = 160 mA 设计，使器件能在微小过流与短路之间实现可靠区分，保护灵敏且稳定。
- 快速响应：最大动作时间 500 ms，可在短时间内抑制异常电流，保障下游元件安全。
- 可复位性：跳闸后阻值上升至不超过 33 Ω，故障解除并冷却后恢复初始阻值（12 Ω 以上），无需更换，降低维护频次与成本。
- 宽电压适配：耐压达 250 V，适合多数直流与交流低压系统应用。
- 插件封装：便于人工焊接与设备维修，适配通用 PCB 布局与更换流程。
三、工作原理简述
RL250-080 通过内部材料在过流时发生电阻迅速增加来限制电流，达到降流保护的目的。正常工作时器件保持低阻状态（约 12 Ω）；当电流超过设定跳闸值（约 160 mA）并持续一定时间时，器件发热使阻值上升（跳断后阻值 ≤33 Ω），从而限制电流。故障排除并冷却后阻值恢复，器件再次进入工作状态。
四、典型应用场景
- 消费类电子：充电器、适配器、机顶盒等的输入保护。
- 通信设备：路由器、交换机、基站外围模块的过流防护。
- 工业控制：传感器供电、控制信号线路的短路保护。
- 仪器仪表：测试设备电源与信号线的安全保护。
五、安装与使用注意事项
- 请在额定电压和环境温度条件下使用，尽量远离高热源以保证可靠触发与恢复性能。
- 安装时注意留出散热空间，避免多只器件紧密并列导致热叠加影响动作特性。
- 允许多次复位循环，但若器件频繁跳闸，应排查系统根本原因而非长期依赖器件保护。
- 禁止用短路或导线替代器件，以免失去过流保护功能并引发安全隐患。
六、质量与供应
RL250-080 为 RUILON（瑞隆源）标准产品，经过出厂校验通过，适合批量采购与替换性维护。封装为插件式，便于后期维修与现场更换。关于认证、最低起订量与交期等具体商务信息，请与供应商或经销商联系获取最新资料。

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.
