1812L010/100GR 自恢复保险丝产品概述

一、产品基本信息定位

该产品为LUTE(陆特) 品牌旗下的贴片式自恢复保险丝(PPTC),型号中“1812”对应英制贴片封装尺寸,“100GR”明确100V耐压等级,核心定位为低压小电流电路的过流保护器件,适配高密度贴片组装需求,可替代传统一次性保险丝,实现故障排除后的自动恢复。

二、核心电气参数深度解析

1. 电压与电流关键阈值

  • 最大耐压Vmax=100V:可覆盖低压直流/交流电路(如12V、24V、48V电源系统),避免过压击穿;
  • 保持电流Ihold=100mA:电路正常工作时可长期稳定导通的最大电流(核心阈值,电流≤100mA时不动作);
  • 跳闸电流Itrip=250mA:触发动作的最小电流(阈值为保持电流的2.5倍,避免小波动误动作);
  • 最大持续电流Imax=1A:正常工作时允许的峰值电流(短时间内不触发动作)。

2. 电阻与功率特性

  • 初始阻值Rmin=750mΩ:低阻设计减少电路压降与发热,不影响后端负载正常工作;
  • 跳断后阻值R1max=15Ω:动作后高阻可有效限制故障电流(≤100V时,故障电流≤6.67A),保护敏感器件;
  • 消耗功率Pd=1W:正常工作时的功率损耗极低,对系统能效影响可忽略。

3. 动作与环境适应性

  • 动作时间1.5s:在跳闸电流下的响应速度适中(既避免瞬态浪涌误动作,又能及时切断故障);
  • 工作温度-40℃~+85℃:宽温覆盖工业、车载及便携式设备的典型环境(如车载-40℃低温、车间+60℃高温)。

三、封装与物理特性

采用1812贴片封装,公制尺寸为:

  • 长度4.73mm、宽度3.41mm、高度1.1mm;
    体积小巧,适配0.8mm及以上 pitch 的贴片组装工艺,可满足高密度电路板(如智能手机主板、小型电源模块)的布局需求;高度仅1.1mm,适合薄型电子设备的内部集成。

四、典型应用场景

  1. 便携式电子设备:手机、平板、智能手环的电池保护回路(Ihold100mA匹配小容量电池输出),以及USB接口、充电端口的过流防护;
  2. 小型电源模块:100V以内的低压电源(如5V/12V开关电源)输出端,保护后端负载(如LED灯、传感器)免受过流冲击;
  3. 工业控制电路:传感器节点、PLC辅助控制回路的过流保护,宽温特性适应车间-20℃~+60℃的环境;
  4. 汽车电子辅助部件:车载小功率设备(如行车记录仪、氛围灯)的过流保护,符合-40℃~+85℃的车载温区要求;
  5. 通信接口防护:以太网接口、RS485总线的过流保护,避免设备因瞬态浪涌或短路损坏。

五、性能优势总结

该产品凭借以下特性,成为多场景过流保护的优选器件:

  • 宽温稳定:无需额外降额设计,适配极端温度环境;
  • 低阻高效:初始750mΩ阻值+1W低损耗,不影响电路能效;
  • 精准可靠:阈值明确、响应适中,误动作率低;
  • 自恢复特性:故障排除后自动导通,无需手动更换,降低维护成本;
  • 易组装性:1812贴片封装适配自动化贴装,适合批量生产。

综上,1812L010/100GR可满足低压小电流电路的过流保护需求,广泛应用于消费电子、工业控制、汽车电子等领域。

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
