1210L300/24WR 产品概述

一、产品简介

1210L300/24WR 是陆特(LUTE)推出的一款1210封装微型过流/过温保护元件,专为空间受限但需承受高电压、大电流的应用场景设计。器件占用面积小,厚度低,适配表面贴装工艺,常用于汽车电子及Type-C端口的过流、过温保护。

二、主要性能参数

  • 允许耐压(Vmax):24V
  • 最大可通过电流(Imax):100A
  • 保持电流(Ihold):3A
  • 跳闸电流(Itrip):6A
  • 跳闸时间(典型):4s
  • 功耗(Pd):1.1W
  • 初始态阻值(Rmin):10mΩ
  • 跳断后阻值(R1max):60mΩ
  • 工作温度范围:-40℃ ~ +85℃
  • 尺寸(长×宽×高):3.5mm × 2.8mm × 1.8mm
  • 封装:1210(SMD)

三、产品特点

  • 体积小、厚度低,便于在紧凑型板级设计中布局。
  • 高耐压与高通过电流能力,能承受瞬态冲击和大电流负载。
  • 明确的保持/跳闸电流(3A/6A),适合Type-C及车载子回路的过流设定。
  • 跳断后阻值上升至最大60mΩ,可限制故障电流并降低持续发热。
  • 宽工作温度范围,满足工业级和车规环境要求。
  • 与常见SMD工艺兼容,便于自动化贴装与回流焊接。

四、典型应用场景

  • 汽车电子子系统:车载充电、信息娱乐系统、电源分配保护等。
  • Type-C / PD 接口:端口过流、短路与发热异常保护。
  • 工业电源与通信设备:对空间与可靠性有较高要求的输出防护。
  • 电池管理辅助保护电路。

五、选型与使用建议

  • 设计时应根据最大连续工作电流与熔断特性留有适当裕量:Ihold 为 3A,连续工作电流建议不接近或超过此值。
  • 对瞬态冲击(例如插拔、短路)需校核器件的 Imax 与跳闸时间,必要时配合限流或缓启动电路。
  • 由于 Pd 为 1.1W,建议在PCB布局上提供良好散热路径,必要时增大铜箔面积或加装散热介质。
  • 在车规或高温环境中,应按最高工作温度与热升特性做热仿真,避免长期偏置导致特性漂移。

六、封装与可靠性

1210SMD 封装(3.5×2.8×1.8mm)利于自动化生产与高密度布板。器件通过宽温测试及高压、循环载流试验,适合长期车载与工业应用。推荐在量产前做样片验证(包括焊接工艺可靠性与热循环测试)以确保在目标系统中的稳定性。

总结:1210L300/24WR 以其小尺寸、高耐压高电流能力及明确的动作特性,适合用于Type-C端口和汽车电子的过流过温保护,是需要在有限空间内实现可靠保护的优选器件。

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
