1812L150/36GR 自恢复保险丝产品概述

1812L150/36GR是LUTE(陆特)品牌推出的表面贴装式自恢复保险丝(PPTC),专为低压电路过流保护设计,兼具小封装、大电流能力与宽温适应性,可覆盖消费电子、工业控制等多场景需求。

一、产品基本信息

该型号命名遵循行业逻辑:1812对应英制封装尺寸(公制4.73mm×3.41mm×1.5mm);L150关联核心保持电流(1.5A);36GR明确最大耐压(36V)。产品属于聚合物正温度系数(PPTC)器件,通过自身温度变化实现过流保护与自恢复,无需外部控制电路。

二、核心电性能参数

关键电性能经严格测试,指标清晰可靠:

  • 耐压与电流能力:最大耐压(Vmax)36V,适配12V/24V等低压系统;峰值电流(Imax)40A,支持短时间大电流冲击;保持电流(Ihold)1.5A(25℃),为电路正常工作可稳定承载的最大电流;跳闸电流(Itrip)3A(25℃),是触发保护动作的最小电流(符合PPTC“跳闸电流≈2×保持电流”的设计逻辑)。
  • 阻值特性:初始态最小阻值(Rmin)40mΩ,导通损耗极低,不影响电路信号/功率传输;跳断后最大阻值(R1max)160mΩ,故障排除后阻值恢复稳定,不干扰电路后续功能。
  • 动作与功耗:典型动作时间500ms(25℃、Itrip电流下测试),过流时快速切断电路;最大消耗功率(Pd)1.2W,确保器件工作热稳定性。

三、机械封装与尺寸

产品采用1812表面贴装封装,具体尺寸为:长度4.73mm、宽度3.41mm、高度1.5mm,兼容SMT自动贴装工艺,可集成于高密度PCB板,有效节省电路空间。封装结构坚固,抗机械振动性能良好,适合批量生产与复杂工况。

四、环境适应性

工作温度范围为**-40℃~+85℃**,覆盖大多数民用与工业场景:低温环境(如北方户外设备)下仍保持稳定保护性能;高温环境(如密闭电子设备内部)下不会因过热失效,可靠性突出。

五、典型应用场景

结合参数特性,适用于以下场景:

  1. 消费电子:移动电源、手机充电器、蓝牙耳机的过流保护,防止短路/过载损坏电池与电路;
  2. 工业控制:小型电机驱动、传感器模块、PLC I/O端口防护,避免过流导致设备故障;
  3. 通信设备:路由器、交换机、光模块电源端口保护,保障数据传输稳定;
  4. 车载电子:12V/24V低压车载电路(如车载充电器、行车记录仪)防护,适配汽车温振环境。

六、关键优势

  1. 低阻高效:初始阻值仅40mΩ,导通损耗远低于传统保险丝,不影响电路正常功率传输;
  2. 自恢复免维护:过流触发后,故障排除(如短路移除)自动恢复导通,无需手动更换,降低维护成本;
  3. 小封装大电流:1812小封装实现40A峰值电流承载,平衡空间需求与防护能力;
  4. 宽温稳定:-40℃~+85℃工作范围,适应不同地域与工况温度变化;
  5. 快速响应:500ms动作时间,过流初期快速切断电路,有效保护后端敏感器件。

综上,1812L150/36GR凭借精准参数、小封装特性与宽温适应性,成为低压电路过流保护的高性价比选择,可满足多领域防护需求。

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
