RUILON RL60-160 高分子自恢复保险丝(PPTC)产品概述

一、产品核心定位

RL60-160是RUILON(瑞隆源)推出的高分子正温度系数(PPTC)自恢复保险丝,属于过流/过温双重保护器件,无需手动更换即可多次实现故障复位,适用于低压电路的可靠保护场景。型号命名中:

  • “RL”代表瑞隆源品牌;
  • “60”对应最大耐压60V;
  • “160”对应保持电流1.6A(取10倍整数);
    封装规格为φ3mm×L16.3mm圆柱型,是针对小型化、宽温环境设计的经济型保护方案。

二、关键电气参数解析

各参数需结合实际应用理解核心意义,避免盲目选型:

1. 耐压与电流承载能力

  • 最大耐压Vmax=60V:器件正常工作及故障状态下可耐受的最高电压,超过会导致绝缘击穿,适配5V~48V低压电路(如电池组、小家电电源)。
  • 最大电流Imax=40A:瞬间脉冲电流耐受极限(非持续),可应对短时间浪涌(如电机启动、电容充电)而不损坏。
  • 保持电流Ihold=1.6A:正常工作时不触发保护的最大持续电流,电路电流≤1.6A时,器件保持低阻导通。
  • 跳闸电流Itrip=3.2A:触发保护的最小电流(典型值),电流≥3.2A时,器件在动作时间内切换至高阻态,限制故障电流。

2. 阻值与功耗特性

  • 初始阻值Rmin=90mΩ:正常导通时的低阻值,压降极小(如1.6A工作电流下,压降≈144mV),对电路效率影响可忽略。
  • 跳断后阻值R1max=240mΩ:保护状态下的高阻态,可将故障电流限制在安全范围(如60V下,故障电流≈250mA)。
  • 最大功耗Pd=1.98W:器件允许的最大持续功耗,需结合工作电压核算(如12V下,最大允许电流≈165mA,远低于跳闸电流)。

3. 动作时间与温度范围

  • 动作时间=11.4s(典型值):在3.2A跳闸电流下的动作时间,属于慢断型,可避免瞬间浪涌(如0.5s内脉冲)误触发,提升电路稳定性。
  • 工作温度=-40℃~+85℃:宽温范围覆盖工业级环境(如户外传感器、车载小模块),满足极端温度下的可靠性要求。

三、物理特性与封装

RL60-160采用圆柱型封装,尺寸为φ3mm×L16.3mm,体积小巧,可适配紧凑空间(如充电头、电池组内部)。封装材质耐温、抗冲击,支持波峰焊或手工焊接,引脚设计便于安装固定,无需额外散热结构。

四、典型应用场景

结合参数特性,RL60-160适用于以下场景:

  1. 电池保护:18650/21700电池组(3~4串,≤16.8V)、移动电源、蓝牙耳机充电仓的过流防护;
  2. 小家电控制:豆浆机、加湿器、小型充电器的电源端保护,避免过流损坏控制板;
  3. 工业小模块:传感器节点、PLC辅助电路、小型电机驱动的过流防护,宽温适配户外/车间环境;
  4. 消费电子配件:USB充电器、车载充电器的输出端保护,应对短路或过载故障。

五、产品优势与价值

  1. 自恢复免维护:故障排除后(如短路解除),器件自动复位至低阻态,无需更换保险丝,降低售后成本;
  2. 低阻高效:初始阻值仅90mΩ,正常工作压降极小,不影响电路整体效率;
  3. 浪涌耐受:Imax=40A应对常见脉冲浪涌,慢断特性适配电机、电容等启动浪涌场景;
  4. 宽温可靠:-40℃~+85℃覆盖绝大多数应用环境,适合户外、车载等极端温度场景;
  5. 经济实用:体积小、成本低,适合批量应用于小型化设备,平衡保护性能与成本。

RL60-160通过精准的参数设计,兼顾了保护可靠性与应用灵活性,是低压电路过流保护的高性价比选择。

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
