1206L075/36NR 产品概述

一、产品简介

1206L075/36NR 是陆特(LUTE)推出的一款小体积复位型过流/过温保护器件,采用1206表面贴装封装,专为汽车电子及工业控制端口等狭小空间的过流保护设计。产品在正常工作时阻值低、耐冲击电流能力强,发生过流或过温时能够快速跳断并在故障消除后自动恢复,便于维护与重复使用。

二、主要性能参数

  • 最大耐压 Vmax:36 V
  • 最大电流 Imax:40 A(瞬态承受能力)
  • 保持电流 Ihold:0.75 A(750 mA)
  • 跳闸电流 Itrip:1.5 A
  • 功耗 Pd:1 W
  • 初始态阻值 Rmin:90 mΩ
  • 跳断后阻值 R1max:500 mΩ
  • 动作时间:200 ms
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 尺寸(L×W×H):3.6 mm × 1.9 mm × 1.6 mm
  • 封装:1206 表面贴装(SMT)

三、产品特点

  • 体积小、占用PCB空间少,适合空间受限设计。
  • 初始电阻低(≈90 mΩ),在正常工作时电压降和功耗低。
  • 能承受高达40 A的短时冲击电流,具备良好的抗浪涌能力。
  • 跳闸后阻值上升(≤500 mΩ),有效限制故障电流,动作迅速(约200 ms)。
  • 宽温工作范围,适应车规及工业环境的温度变化。
  • 自恢复特性,故障清除后自动恢复导通,降低维护成本。
  • 1206 常见贴片封装,支持标准回流焊工艺,便于自动化生产。

四、典型应用场景

  • 汽车电子系统:车载信息娱乐、摄像头、电源接口、控制模块等端口过流保护。
  • 工业控制:接线端子、通讯接口、电源输入保护、现场模块防护。
  • 消费及便携设备:USB/充电端口、显示模块、传感器供电保护。
  • 其他低压直流系统中需要可复位保护的场合(最高工作电压36 V)。

五、使用建议与注意事项

  • 选型时确认系统的最大持续电流应低于 Ihold(750 mA),并考虑启动冲击电流是否超过 Itrip(1.5 A)。
  • 对于存在较大浪涌或长时间短路情形的系统,应评估是否需并联或改用更高速熔断器;本件适合限流与重复保护,但非瞬断型熔断器替代。
  • 布局建议将器件靠近被保护的输入端并保证良好散热路径,以免环境升温导致误跳。
  • 注意回流焊温度曲线与器件允许峰值温度,避免超温导致性能退化。
  • 跳闸后阻值上升会造成一定的功耗与发热,需在设计中预留热裕量。
  • 建议获取并参考陆特提供的完整数据手册与 I-T、I-V 特性曲线以准确评估实际行为。

六、封装与订购信息

  • 封装形式:1206 SMT(尺寸:3.6 × 1.9 × 1.6 mm)。
  • 品牌:LUTE(陆特)。型号:1206L075/36NR。
  • 常见供货形式为卷带(Tape & Reel)以便贴片机直接上料,具体包装与最小订购量请向供应商或陆特销售咨询并索取数据手册与样片。

总结:1206L075/36NR 以其微小外形、低初始阻值和良好的浪涌承受能力,适合汽车与工业控制等要求体积与可靠性并重的场合。建议在设计初期核查实际工作电流、热环境与浪涌条件,并参考厂商曲线进行验证试验。若需完整数据手册或样品,请联系陆特或其授权分销商。

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
