1206L100/24NR 自恢复过流保护器件产品概述

一、产品核心定位

1206L100/24NR是陆特(LUTE)品牌推出的1206贴片封装自恢复过流保护器件(PPTC),专为低电压、中小电流电路的过流防护设计。核心作用是在电路出现过流故障时快速切断电流,保护后端元器件不受损坏;故障排除后可自动恢复导通,无需人工更换,有效提升电路可靠性与维护效率。

二、关键电气参数深度解析

该器件的参数针对低电压场景优化,核心参数可支撑多数小型电子系统的防护需求:

1. 电压与电流能力

  • 额定耐压(Vmax):24V:适配USB供电、电池系统(如12V/24V电池)等低电压电路,避免过压击穿。
  • 最大耐受电流(Imax):40A:支持短时间峰值电流冲击(如开机瞬间、负载突变),防止器件因瞬间大电流损坏。
  • 保持电流(Ihold):1A:电路正常工作电流需≤1A时,器件保持低阻导通,不影响电路效率。
  • 跳闸电流(Itrip):1.8A:当电流超过1.8A时,器件进入过流响应阶段,300ms内完成跳断动作,精准切断过流。

2. 阻值与功耗

  • 初始态最小阻值(Rmin):50mΩ:低阻设计大幅降低正常工作时的功率损耗,避免额外发热影响电路稳定性。
  • 跳断后最大阻值(R1max):300mΩ:跳断状态下保持高阻,有效阻断过流,保护负载与电源端。
  • 最大消耗功率(Pd):1.2W:满足正常工作与过流状态下的功率承载,长期使用无过热风险。

3. 动作与温度特性

  • 动作时间:300ms(典型值):平衡响应速度与抗干扰性,避免瞬间脉冲(如静电、负载切换)导致误跳断。
  • 工作温度:-40℃~+85℃:覆盖低温(如车载、户外设备)与高温(如小型模块内部散热环境)场景,宽温适应性强。

三、封装与物理特性

该器件采用1206标准贴片封装,实际物理尺寸为:

  • 长度:3.6mm
  • 宽度:1.9mm
  • 高度:1.4mm

尺寸紧凑,符合自动化贴装要求,适合高密度PCB布局(如便携设备、小型模块),有效节省电路空间。

四、核心性能优势

  1. 低损耗高可靠性:初始低阻减少电路功耗,跳断后高阻确保过流阻断效果,长期使用稳定性强。
  2. 自恢复无需维护:过流故障排除后自动恢复导通,无需手动更换保险丝,降低维护成本与停机时间。
  3. 宽温场景适配:-40℃至+85℃的温度范围,覆盖消费电子、工业控制、车载等多领域场景。
  4. 快速响应抗干扰:300ms动作时间兼顾及时性与抗脉冲能力,避免误触发导致电路中断。

五、典型应用场景

  1. 消费电子:手机、平板、蓝牙耳机的电池保护电路,USB充电接口过流防护(防止过充、短路)。
  2. 工业控制:小型传感器模块、PLC输入输出端口的过流保护(避免传感器烧毁)。
  3. 车载电子:车载USB充电口、仪表盘背光电路、小型车载传感器的过流防护(适应-40℃低温启动)。
  4. 通信设备:路由器、交换机电源输入端口,小型基站模块的过流防护(提升设备可靠性)。

六、选型与使用注意事项

  1. 电流匹配:正常工作电流≤1A,峰值电流≤40A,避免超出阈值导致误触发或损坏。
  2. 电压匹配:电路工作电压≤24V,确保器件在额定耐压范围内安全工作。
  3. 焊盘设计:采用标准1206贴片焊盘,避免虚焊导致阻值异常或动作失效。
  4. 温度控制:工作环境温度需在-40℃~+85℃内,超出范围可能影响动作性能。

该器件以紧凑封装、宽温适配与自恢复特性,成为低电压中小电流电路过流防护的高性价比选择。

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
