RL30-300 产品概述

一、产品简介

RL30-300 为 RUILON(瑞隆源)推出的一款插件式自恢复过流保护器件(聚合物自恢复保险器/PPTC),额定电压 30V,典型保持电流 3A,跳闸电流 6A。器件采用插件封装,间距 P=5.1mm,长度 13.2mm,适合通过孔(插件)安装在电源输入或受保护回路中,用于短路与过流防护并在过载解除后自动恢复导通状态,便于维护与重复使用。

二、主要技术参数

  • 额定耐压(Vmax):30V
  • 初始态阻值(Rmin):20mΩ
  • 跳断后阻值(R1max):100mΩ
  • 保持电流(Ihold):3A
  • 跳闸电流(Itrip):6A
  • 最大电流(Imax):40A(一次性短时通过能力,受环境与脉冲宽度影响)
  • 动作时间:10.8s(在规定过流条件下触发时间)
  • 最大耗散功率(Pd):2W
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:插件,针距 P=5.1mm,长度 13.2mm
  • 品牌:RUILON(瑞隆源)

三、产品特性与优势

  • 自动复位:聚合物PTC材料在过流升温后阻值显著上升,保护电路;故障清除后冷却恢复低阻态,无需更换元件。
  • 体积小、安装方便:通过孔插件结构,适配常见电路板安装工艺,便于现场更换与检修。
  • 低初始阻抗:Rmin 仅 20mΩ,正常工作时压降和功耗低,适合低压供电系统。
  • 宽温度范围:-40~+85 ℃,适用于多数工业和民用环境。
  • 瞬时耐受能力:Imax 40A 表明对短路电流有一定承受能力,但应避免长期超额通过。

四、典型应用

  • 30V 以内的直流电源输入保护(如通信设备、电源模块、便携设备)。
  • 电池组及充电线路过流保护。
  • 汽车电子低压子系统(符合工作温度条件下)。
  • 工业控制板、消费电子与仪器仪表的保护元件。

五、推荐使用与注意事项

  • 连续工作电流应小于或等于 Ihold(3A),长期接近 Ihold 时建议留有裕量并注意散热。若实际最大工作电流常接近该值,应选用更高规格器件。
  • Itrip(6A)为触发跳闸的典型值,动作时间 10.8s 表示在该电流水平下器件将在数秒级动作,瞬时短路电流和持续时间会影响实际行为。
  • Pd(2W)为参考耗散能力,器件在高功耗工况下会升温,周围器件与封装环境会影响冷却性能,应避免密集聚集发热源。
  • 安装时保证插件焊点可靠、与电路板铜箔有良好热散路径;避免直接置于高温元件或封闭空间中影响散热。
  • 不建议用于超过额定耐压(30V)的场合;在强电磁干扰或需要快速断开(微秒级)的应用上,PPTC 并非理想选择,应配合熔断器或电子断路器使用。
  • 对重复触发的场合,需评估PTC材料的长期稳定性与循环寿命。

六、封装与订购信息

  • 封装形式:插件(P=5.1mm),长度 13.2mm,便于 DIP 样式装配。
  • 型号:RL30-300,品牌:RUILON(瑞隆源)。
  • 订购时请确认环境温度、最大持续电流及短路条件,必要时咨询供应商获取完整的 I–T 曲线、热阻与寿命数据以做最终选型。

总结:RL30-300 适用于 30V 以内、需自动复位保护且连续电流不超过 3A 的低压供电场景,具有低阻、插件安装与宽温特性,适合在电源输入与电池保护等应用中作为经济高效的过流保护方案。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
