0805L100/16AR 可恢复过流保护器件产品概述

一、产品基本信息

本产品为LUTE(陆特)品牌推出的高分子正温度系数热敏电阻(PPTC),属于可恢复过流保护器件,核心型号为0805L100/16AR。其型号含义解析如下:

  • 0805:英制贴片封装尺寸(对应公制实测尺寸约2.3mm×1.5mm);
  • L100:代表保持电流(Ihold)=1A(“100”可理解为1000mA,即1A);
  • 16:最大工作耐压(Vmax)=16V;
  • AR:系列后缀,通常表示封装优化或适配低压电路的特定版本。

二、核心电气参数与技术指标

本产品的参数经过严格测试,满足低压电路过流保护的核心需求,关键指标如下:

1. 耐压与电流能力

  • 最大工作电压(Vmax):16V
    持续工作时的电压上限,过流跳断后器件不击穿,适配12V/16V等低压系统;
  • 最大峰值电流(Imax):40A
    短时间内可承受的脉冲电流(如启动浪涌、静电放电),避免突发大电流损坏;
  • 保持电流(Ihold):1A
    正常工作状态下允许的最大持续电流,电路无异常时器件不动作;
  • 跳闸电流(Itrip):2A
    触发过流保护的最小电流(约为保持电流的2倍),符合PPTC典型特性,避免误触发。

2. 阻值与功耗

  • 初始态最小阻值(Rmin):40mΩ
    常温下的低阻值,1A电流下仅产生40mV压降,大幅减少正常工作时的功耗;
  • 跳断后最大阻值(R1max):270mΩ
    过流动作后阻值急剧上升,限制电流至安全范围(通常<100mA),保护后级器件;
  • 最大允许功耗(Pd):800mW
    正常工作时的功率耗散上限,避免器件过热失效。

3. 动作与环境特性

  • 典型动作时间:300ms
    过流触发后至阻值上升至高阻态的时间,及时响应保护需求;
  • 工作温度范围:-40℃~+85℃
    宽温范围适配工业、汽车等复杂环境(如北方冬季户外设备、南方夏季车载电路)。

三、封装与物理特性

本产品采用0805贴片封装,符合表面贴装工艺要求,物理尺寸为:

  • 长度:2.3mm;
  • 宽度:1.5mm;
  • 高度:1.2mm。

封装优势:

  • 小型化设计:节省PCB布局空间,适配智能手机、小型通信模块等高密度电路;
  • 贴片式结构:兼容自动贴装设备,提升生产效率,降低人工成本;
  • 无引线设计:减少寄生电感/电容,优化电路高频特性。

四、典型应用场景

结合参数特性,本产品主要应用于低压、中等功率的过流保护场景:

  1. 消费电子:智能手机/平板的电池充电电路、USB接口保护;蓝牙耳机、智能手表的电源模块防护;
  2. 工业控制:小型传感器(温度/压力)的供电电路;低功耗PLC的输入输出接口;
  3. 通信设备:路由器/交换机的以太网接口、电源模块;小型基站的射频模块供电;
  4. 汽车电子(辅助电路):车载USB充电口、胎压监测模块的供电保护。

五、关键性能优势

  1. 低功耗高效能:初始阻值仅40mΩ,正常工作压降极小,不影响电路功能;
  2. 快速响应保护:300ms动作时间,及时切断过流,避免IC、电容等器件损坏;
  3. 可恢复性:过流消失后自动恢复低阻态,无需更换,降低维护成本;
  4. 宽温适应性:-40℃~+85℃满足极端环境需求;
  5. 高可靠性:经过温度循环、湿热测试,长期工作稳定;
  6. 大峰值电流承受:40A能力应对启动浪涌、静电放电等突发场景。

六、工作原理简述

本产品基于PPTC材料特性实现可恢复保护:

  • 正常状态:常温下,导电填料形成连续网络,阻值低(40mΩ),允许正常电流通过;
  • 过流触发:电流超过2A时,焦耳热使聚合物升温膨胀,破坏导电网络,阻值升至270mΩ以上,限制电流;
  • 恢复状态:过流消失后,器件降温,聚合物收缩,导电网络重建,阻值恢复初始低阻态。

总结:0805L100/16AR作为小型化、高性能的可恢复过流保护器件,凭借低阻、快速响应、宽温适配等优势,成为低压电路过流保护的理想选择,广泛覆盖消费电子、工业控制、通信等领域。

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.
