1206L150/24NR 过流保护器件产品概述

1206L150/24NR是LUTE(陆特)品牌推出的1206封装自恢复过流保护器件(PPTC类),专为中低压电路设计,兼具小体积、低功耗、快响应等特点,可广泛应用于消费电子、汽车电子、工业控制等领域。

一、产品基本信息与定位

该器件为表面贴装式过流保护元件,封装规格为1206(英制尺寸,对应公制3216),尺寸为3.6mm(长)×1.9mm(宽)×1.6mm(高),适配常规SMT生产线,可直接集成于高密度PCB设计。核心定位是**≤24V中低压电路的低成本、高可靠性过流保护方案**,替代传统一次性保险丝,具备自恢复特性,无需人工更换即可重复使用。

二、核心电气参数解析

关键参数直接决定保护能力,具体解析如下:

  • 最大耐压(Vmax):24V:长期可承受的最大直流/交流电压,适配5V、12V、24V等常见中低压电源;
  • 最大电流(Imax):40A:故障状态下短时间承受的峰值电流,抗浪涌能力强;
  • 保持电流(Ihold):1.5A:常温(25℃)下持续导通的最大电流,电路正常工作电流需≤此值;
  • 跳闸电流(Itrip):3A:常温下触发跳断的最小电流,过流≥3A时300ms内切断回路;
  • 功耗(Pd):1.2W:正常工作最大允许功耗,需结合散热设计;
  • 初始阻值(Rmin):25mΩ:低导通电阻,减少电路损耗;
  • 跳断后阻值(R1max):130mΩ:高阻状态有效限制故障电流;
  • 动作时间:300ms:快速响应,阻止故障扩散;
  • 工作温度:-40℃~+85℃:宽温区适应车载、户外等恶劣环境。

三、关键性能特点

  1. 低损耗:25mΩ初始阻值远低于传统保险丝,提升电池供电系统效率;
  2. 快响应:300ms动作时间及时切断故障回路,保护敏感元件;
  3. 自恢复:故障排除后自动恢复导通,降低维护成本;
  4. 宽温适配:-40℃~+85℃满足车载、工业场景需求;
  5. 小体积高密度:1206封装适配紧凑PCB,适合智能穿戴、小型医疗仪器;
  6. 抗冲击:40A最大电流承受能力,抵御浪涌电流(如电源启动、负载突变)。

四、典型应用场景

  • 消费电子:智能手机、平板的电池保护、USB接口过流保护;
  • 汽车电子:车载USB充电口、仪表盘模块、传感器电路保护;
  • 工业控制:PLC输入/输出模块、小型电机驱动电路保护;
  • 通信设备:路由器、交换机电源接口、PoE模块保护;
  • 医疗设备:便携式血糖仪、血压计等小型仪器电路保护。

五、封装与可靠性说明

  1. 封装工艺:RoHS环保标准,适配回流焊/波峰焊(焊接温度≤260℃,3秒内);
  2. 可靠性测试:通过温度循环(-40℃~+85℃,500次)、湿度测试(85℃/85%RH,1000小时);
  3. 重复性能:多次跳断-恢复无明显衰减,长期稳定。

六、选型与使用注意事项

  1. 选型匹配:工作电压≤24V、正常电流≤1.5A、故障电流≥3A;
  2. 使用要点:焊接避免机械应力,与发热元件保持≥5mm距离,浪涌场景配合TVS管使用。

综上,1206L150/24NR是性价比高的中低压过流保护器件,为多种电子系统提供稳定保护方案。

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
