1812L200/16GR 自恢复保险丝产品概述

一、产品基本定位与品牌背景

1812L200/16GR是国内过流保护器件厂商陆特(LUTE) 推出的一款聚合物正温度系数(PPTC)自恢复保险丝,核心作用是为低压电路提供过流/过温保护——故障排除后无需手动更换,可自动复位,适配小型化电子设备的高密度电路设计需求。陆特作为专注过流保护领域的品牌,其产品以高可靠性、低损耗为特点,这款器件正是针对低压场景优化的典型代表。

二、核心电性能参数解析

这款器件的电性能参数经过精准匹配,适配5V/12V等低压系统的保护需求,关键参数解读如下:

  • 耐压(Vmax=16V):可稳定承受16V以内的电路电压,过流保护时避免器件击穿,防止二次故障;
  • 保持电流(Ihold=2A):电路正常工作时允许的最大持续电流(如设备工作电流≤1.5A时,器件可长期稳定运行);
  • 跳闸电流(Itrip=4A):触发保护的最小电流(当电路因短路、过载升至4A及以上时,器件启动保护);
  • 动作时间(2s):从电流达到跳闸值到跳断的响应时间,既避免开机浪涌、短暂脉冲等误触发,又能快速切断故障电流;
  • 初始态阻值(Rmin=20mΩ):正常状态下电阻极低,可减少电路功率损耗(P=I²R),降低设备发热与功耗;
  • 跳断后阻值(R1max=100mΩ):跳断后电阻大幅提升,有效限制故障电流,保护后端敏感元件(如芯片、电池);
  • 最大电流(Imax=100A):可承受瞬时浪涌(如静电放电、瞬间短路),避免器件本身损坏;
  • 消耗功率(Pd=1W):正常工作时的最大允许功耗,确保器件在发热环境下稳定工作。

三、封装与物理特性

1812L200/16GR采用1812贴片封装(英制尺寸,公制对应4.73mm×3.41mm×1.3mm),具备以下优势:

  • 适配自动化贴装设备,提高生产效率,降低人工成本;
  • 体积小巧,节省PCB空间,适合智能手机、智能穿戴等高密度电路;
  • 重量轻,对便携设备的整体重量影响极小,符合轻量化设计趋势。

四、典型应用场景

结合参数特点,这款器件主要应用于低压小型设备:

  1. 智能穿戴:智能手环、电子手表的电池充电/放电回路,保护电池免受过流损坏;
  2. 便携式电子:充电宝、蓝牙耳机的电源管理模块,应对充电过载或短路风险;
  3. 消费电子配件:手机充电器、数据线的过流保护,提升配件可靠性与使用寿命;
  4. 小型工业节点:低功耗传感器、物联网终端的电源保护,适应宽温环境(-40℃~+85℃)。

五、产品优势与价值

相比传统一次性保险丝,1812L200/16GR具备明显竞争力:

  1. 自恢复特性:故障排除后(如短路点修复),器件自动恢复低阻态,无需更换,降低维护成本;
  2. 低损耗设计:20mΩ初始电阻减少电路发热,提升设备能效与续航时间;
  3. 宽温适应性:工作温度覆盖-40℃~+85℃,可满足户外便携设备的温度需求;
  4. 快速响应平衡:2s动作时间既避免误触发,又能在故障时快速保护,适配大多数低压电路场景。

六、使用注意事项

  1. 电路工作电压需≤16V,避免高压击穿;
  2. 正常工作电流需≤2A,超过可能导致器件误跳断;
  3. 贴装时遵循1812封装的焊接工艺(如回流焊温度),避免虚焊影响性能;
  4. 故障后需确认电路无短路再恢复,避免重复跳断损坏器件。

这款器件凭借紧凑封装、低损耗与自恢复特性,成为低压小型电子设备过流保护的高性价比选择,适配陆特品牌的可靠性要求,可满足多数民用电子的设计需求。

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
