LUTE 0805L003/80XR 产品概述

一、产品概述

0805L003/80XR 是陆特(LUTE)推出的一款微型自恢复式过流保护元件(PTC 自恢复保险),采用标准 0805 封装,适用于对体积和响应速度有较高要求的便携式和板载电子设备。器件在过流时由低阻态迅速跳入高阻态限制电流,故障排除后可自行恢复,提供可靠的重复保护方案。

二、主要参数

  • 耐压(Vmax):80 V
  • 最大电流(Imax):10 A(短时冲击能力)
  • 保持电流(Ihold):30 mA
  • 跳闸电流(Itrip):90 mA
  • 功耗(Pd):500 mW
  • 初始态阻值(Rmin):6 Ω
  • 跳断后阻值(R1max):50 Ω
  • 动作时间:约 1 s(在规定过流条件下)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 尺寸(长×宽×高):2.2 mm × 1.5 mm × 0.9 mm
  • 品牌 / 封装:LUTE(陆特) / 0805

三、产品特点

  • 极小封装:0805 尺寸适合高密度 SMT 布局,占板空间小。
  • 低保持电流:30 mA 的保持电流适合对微电流供电路径的可靠保护,不易误触发。
  • 可复位保护:跳闸后阻值显著上升至 ≤50 Ω,有效限制故障电流;移除故障后自动恢复为初始阻值。
  • 宽工作温度范围,适应工业级应用环境。
  • 500 mW 功耗等级与 80 V 耐压使其可用于较高电压、低功率的保护场景。

四、典型应用

  • 移动设备与消费电子的小电流分支保护
  • IoT、传感器模块及通信终端的板级过流保护
  • 显示、接口(如 USB 辅助线路)及外围电路保护
  • 低功耗电源管理和系统复位保护

五、封装与可靠性

器件符合 0805 SMT 工艺,建议按厂商推荐的回流焊温度曲线进行贴装以保证可靠性。工作温度范围 -40~+85 ℃,并具备重复复位能力,适合长期板载使用。

六、使用建议与注意事项

  • 将元件尽量靠近被保护电路放置以减少寄生阻抗与响应延迟。
  • 确认实际工作电流低于保持电流,避免长期发热导致漂移或误动作。
  • 在高温或连续大电流场合,应考虑功率与温度的降额使用,避免超过 500 mW 的散热能力。
  • 对于需承受持续大电流或高能量浪涌的应用,应配合其它保护器件(如快断熔丝、TVS)共同设计。

七、总结

0805L003/80XR 为一款体积小、响应快、可复位的过流保护器件,适合对板面空间敏感且需稳定重复保护的电子产品。选型时请结合实际工作电流、环境温度和浪涌能量,参考厂商详细资料以获得最佳保护效果。

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
