RL250-800 产品概述
一、产品简介
RL250-800 为 RUILON（瑞隆源）系列插件式自恢复保险器，额定耐压 250V，额定保持电流 Ihold = 800mA，适用于对过流保护、短路保护要求的交流/直流供电线路。器件为插件封装，针距 P=5.1mm，整体长度 20mm，适配通用插座或波峰/手工焊接安装。
二、主要电气参数
- 额定耐压：Vmax = 250V
- 保持电流：Ihold = 800mA
- 跳闸电流：Itrip = 1.6A（在规定测试条件下触发）
- 最大瞬时电流：Imax = 5A（短时耐受，不宜作为长期工作电流）
- 动作时间：约 18s（在指定过流条件下）
- 功耗额定：Pd = 3.5W
- 初始态阻值：Rmin = 400mΩ
- 跳闸后最大阻值：R1max = 3Ω
三、产品特点
- 自恢复设计：过流时自动限流并在故障清除后恢复导通，减少更换频次和维护成本。
- 插件封装：P=5.1mm，安装方便、可重复插拔，便于维修与替换。
- 低初始阻抗：Rmin≈0.4Ω，有利于正常工作时的压降最小化。
- 明确的保护动作特性：Ihold 与 Itrip 定义清楚，便于设计冗余与选型。
四、典型应用场景
适用于电源模块、适配器、家用电器、照明驱动、通信设备及电子仪器中对中低电流过载保护的场合，尤其是需要可恢复保护以避免一次性熔断器频繁更换的系统。
五、选型与使用建议
- 常态工作电流应保持低于 Ihold（800mA），并考虑环境温度对 Ihold 的影响与安全裕度。
- Itrip 与动作时间受温度和装配散热影响，建议在目标应用环境下做实测验证。
- Imax = 5A 为短时通过能力，发生短路时仍可能造成器件发热或损坏，不宜作为常态冲击参考。
- 安装时保证良好接触与适当散热空间，避免邻近高热源影响器件动作特性。
如需电气曲线、热阻或样件试用，请提供具体应用工况，便于给出更精确的选型建议。

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.
