RL30-250 产品概述
一、产品简介
RL30-250 是 RUILON（瑞隆源）推出的一款插件式自恢复聚合物PTC保护器件，额定耐压30V，适用于需要过流保护并能自动复位的电子线路。器件为插装封装，便于维修更换和样机调试。
二、主要性能参数
- 最大耐压（Vmax）：30V
- 最大承受脉冲/峰值电流（Imax）：40A
- 保持电流（Ihold）：2.5A（连续安全通过电流）
- 跳闸电流（Itrip）：5A（器件进入高阻态的门槛）
- 功率消耗（Pd）：1.2W（稳态功耗参考）
- 初始态阻值（Rmin）：20mΩ
- 跳断后阻值（R1max）：100mΩ（自恢复后高阻态参考）
- 动作时间：10.3s（典型，实际随过流幅度与环境变化）
- 工作温度范围：-40℃ ~ +85℃
三、产品特性与优势
- 插件设计，便于快速替换与电路调试；
- 自恢复功能，故障消除后自动恢复低阻态，降低维护成本；
- 宽温度范围与较高的峰值电流承受能力，适应工业及商用环境；
- 低初始内阻，正常工作时压降与发热小。
四、典型应用场景
- 消费电子与便携设备的电源输入保护；
- 通讯设备、网关与交换机的短路/过流保护；
- 汽车电子（非关键安全回路）、电池管理与充电接口（需确认30V耐压限制）；
- 工业控制模块与仪表的局部过流防护。
五、选型与安装建议
- 连续工作电流应小于 Ihold（2.5A），如存在启动浪涌需确认器件可承受的峰值（Imax=40A）；
- 选择时留有余量，实际工作电流建议≤ Ihold × 0.8，以避免误触发；
- 插件安装时预留散热空间，远离高温元件，保证通风；
- 注意线路板孔径及插装牢固性，避免振动或接触不良。
六、使用与维护注意事项
- 动作时间受过流倍数与环境温度影响，遇频繁触发时应查明故障原因；
- 不建议在超过30V的系统中使用；超过器件额定极限可能导致永久损伤；
- 器件自恢复后阻值上升，若恢复不完全需更换；
- 订购与验收时请确认批次与相关检测报告。
七、包装与品质保证
RUILON 提供商业级出货包装与质量检验，支持批量供货与技术咨询。具体认证（如 RoHS/UL 等）与检测数据可在采购时与供应方确认。
Request for quote
Send RFQ
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.
