1812L160/30GR 产品概述

一、产品简介

1812L160/30GR 是陆特(LUTE)推出的一款微型自恢复过流保护器件,采用1812封装设计,占用空间小、可在潮湿与振动环境下可靠工作。器件为过流/过温保护用途优化,适合汽车电子与工业控制接线端口等对体积与可靠性要求较高的场合,能在过流发生后自动跳闸并在故障解除后恢复导通,降低维护成本与意外停机风险。

二、主要参数

  • 最大工作电压(Vmax):30 V
  • 最大持续电流(Imax):40 A
  • 保持电流(Ihold):1.6 A
  • 跳闸电流(Itrip):3.2 A
  • 功耗(Pd):1.2 W
  • 初始态阻值(Rmin):30 mΩ
  • 跳断后最大阻值(R1max):130 mΩ
  • 跳闸动作时间:1 s
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 尺寸(L×W×H):4.73 mm × 3.41 mm × 1.5 mm
  • 封装:1812(表面贴装)

三、结构与封装

1812封装提供了紧凑而稳固的贴片形式,适配常见的SMT生产流程。器件内部采用聚合物热敏材料实现自恢复特性,常态下保持低阻抗以保证电路正常工作;当电流或温度超过设定值时,器件内部升温并迅速增阻,从而限制电流,保护下游电路元件免受损坏。

四、主要特性

  • 体积小、占板面积低:适合高密度PCB布局。
  • 快速响应:典型跳闸时间约1秒,可有效抑制短路与过流事件。
  • 可自恢复:故障消除后阻值恢复,减少更换频率。
  • 宽温度适应性:-40 ℃至+85 ℃,适用于汽车级与工业级工作环境。
  • 低初始电阻:30 mΩ的初始阻值有利于降低功耗与发热。
  • 大电流承载:最高可达40 A,适配高功率通路的保护需求。

五、典型应用场景

  • 汽车电子:车载控制模块、车灯总成、充电/辅助电源接口等端口过流保护。
  • 工业控制:PLC接线端、传感器供电回路、继电器驱动线路的过流与过温保护。
  • 通信与电源:小型电源模块、分配总线及接口保护。
  • 其他需要小体积、高可靠性过流保护的场合。

六、设计与安装注意事项

  • 额定电流匹配:选择器件时,应根据系统正常工作电流与启动/冲击电流特性,确保Ihold高于正常工作电流且Itrip低于可能损害负载的电流水平。
  • 散热与布局:尽管器件自恢复,长时间接近Pd限制会导致持续升温,建议在器件周围留有合理散热区域并避免紧邻高温器件。
  • 焊接工艺:遵循SMT回流温度曲线,避免超过制造商推荐的峰值温度与时间,以免影响器件性能。
  • 老化与预留裕度:对于汽车与工业应用,考虑温度漂移与长期老化,适当提高裕度以保证长期可靠性。

七、可靠性与环境指标

1812L160/30GR 设计符合车规与工控常见的环境要求,工作温度范围广、对湿热与振动环境具有良好适应性。器件在多次过流循环后仍能保持自恢复功能,但建议在设计阶段进行必要的寿命与耐久性评估(如多次跳闸测试、热循环测试)以满足具体项目的可靠性标准。

八、选型与订购建议

在选型时,优先核对系统峰值电流、持续电流以及允许的动作时间,若系统存在频繁短时突发电流,应选择具有更高Imax或更大热容的型号以避免误动作。陆特(LUTE)品牌提供一致的质量保证与技术支持,订购时请确认型号完整标识“1812L160/30GR”并与供应商确认包装规格与供货周期。

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
