RL250-200 产品概述
一、产品简介
RL250-200 为 RUILON（瑞隆源）推出的一款插件式自恢复熔断器（Resettable Fuse）。该器件在过流发生时通过自身电阻升高实现限流和保护，故障消除后可自动冷却恢复导通。适合用于需要重复过流保护和维护方便的电子设备与电源系统。
二、主要技术参数
- 额定耐压（Vmax）：250V
- 最大承受电流（Imax）：5A
- 保持电流（Ihold）：200mA
- 跳闸电流（Itrip）：400mA
- 功耗（Pd）：1.5W
- 初始态阻值（Rmin）：1.5Ω
- 跳断后最大阻值（R1max）：9Ω
- 动作时间：5s（标称值，基于标准试验条件）
- 长度：12mm
- 封装：插件式（具体封装形式资料未注明）
三、特性与优点
- 自恢复设计：过流后自动断开并在冷却后恢复，免替换、维护成本低。
- 响应稳定：标称动作时间和阻值范围明确，利于系统设计与仿真。
- 插件安装：方便更换与维修，适合快速原型和小批量维护。
- 宽耐压：额定耐压250V，覆盖较多交流/直流供电场景。
四、典型应用场景
- 开关电源、适配器及模块输入保护
- 家用电器和消费电子的局部过流保护
- 通信设备、测试仪器的线路保护
- 电池组和充电系统的过流防护（需与系统电压和短路特性匹配）
五、选型与使用建议
- 保证正常工作电流低于 Ihold，并留有裕量（通常建议 20%~50%）。
- 若系统短路电流远高于 Itrip，应同时配合快速断开的保护元件以防瞬态损坏。
- 关注环境温度对 Ihold 的影响，高温会降低保持电流。
- 插件安装时确认机械固定可靠且良好散热路径，以免长期高温加速老化。
六、安全与储存
- 该器件不应作为唯一的故障隔离手段，在高能量短路场景需并用保险丝或断路器。
- 存放于干燥、通风、避免阳光直射的环境，温度与湿度按一般电子元器件要求控制。
- 运输和安装过程中避免强力挤压和过度弯折引脚。
七、订购信息
型号：RL250-200；品牌：RUILON（瑞隆源）。封装形式与包装数量请在采购前与供应商确认，以确保与实际装配工艺匹配。
如需进一步的试验曲线（I–T、I–V）、环境温度特性或封装图纸，可提供具体需求，我可协助整理与比对类似型号的详细数据以便选型。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
