RL30-400 产品概述
一、产品简介
RL30-400 是瑞隆源（RUILON）推出的一款插件式过流保护元件，适用于对 12V/24V 等低压电源系统进行重复自恢复保护。产品通过严格校验，性能稳定可靠，适合工业设备、电源模块、汽车电子、通信设备及消费类电子等场景的短路与过载保护需求。
二、主要参数
- 耐压（Vmax）：30V
- 最大电流（Imax）：40A
- 保持电流（Ihold）：4A
- 跳闸电流（Itrip）：8A
- 消耗功率（Pd）：2.5W
- 初始态阻值（Rmin）：10mΩ
- 跳断后阻值（R1max）：90mΩ
- 动作时间：12.7s（典型/测量条件下）
- 工作温度：-40℃ ~ +85℃
- 长度：14mm
- 封装：插件（Through-hole）
三、核心特性
RL30-400 以低初始阻值和明确的保持/跳闸电流闻名，能在正常工作电流下保持较小压降，同时在过载或短路时迅速升温并进入高阻态以限制电流，避免器件与线路受损。动作时间为 12.7s（测量条件下），适合针对持续性过流或慢速冲击的保护场景。工作温度范围宽，适应性强，插件封装便于维修替换与机加工固定。
四、典型应用
- 汽车电子：车载中控、座椅电机、照明与外设保护（符合 30V 以下系统）
- 电源与适配器：输入端或输出端浪涌/短路保护
- 工业控制：PLC、驱动模块、继电器控制回路的过流保护
- 通信与网络设备：交换机、基站电源防护
- 消费电子：电池管理、充电设备的安全保护
五、安装与使用注意事项
- 插件焊接时避免长时间高温，以防内部材料性能退化；建议按推荐焊接曲线操作并快速冷却。
- 保持周围良好通风与散热，长期在高功耗或高环境温度下工作时，应考虑降额使用或增加散热措施。
- 布局时尽量靠近被保护负载/电源入口安装，以缩短保护回路路径并降低寄生阻抗。
- 若用于频繁短路或高能量冲击场合，应评估器件的寿命与自恢复次数，必要时选用更高额定型号或并联方案。
- 工作环境避免化学腐蚀性气体与长期潮湿，以延长使用寿命。
六、质量与服务
RL30-400 经出厂校验通过，符合企业出货标准；瑞隆源提供一定的质量保证与技术支持，常备库存，便于小批量试产与量产供应。需要更多技术资料（电流-温度曲线、热阻数据、推荐焊接工艺）可联系供应商索取完整数据手册。
如需根据具体应用场景进行选型或并联、散热建议，欢迎提供电路工作电流、环境温度及安装条件，我方可协助评估并给出优化方案。

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.
