2920L700/24GR 产品概述

一、产品简介

2920L700/24GR 是 LUTE(陆特)推出的一款高可靠性表面贴装自恢复保险丝(PTC),封装标称为 2920,实际外形尺寸为长 7.98 mm × 宽 5.44 mm × 高 1.6 mm。该器件在保持小封装占位的同时,实现了高电压与大电流的保护能力,适用于汽车电子及工控端口的过流、过温保护场合。

二、主要技术参数

  • 额定耐压(Vmax):24 V
  • 最大电流(Imax):40 A
  • 保持电流(Ihold):7 A
  • 跳闸电流(Itrip):14 A
  • 消耗功率(Pd):2.5 W
  • 初始态电阻(Rmin):2.5 mΩ
  • 跳断后最大电阻(R1max):15 mΩ
  • 动作时间(典型):6 s
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装尺寸:7.98 × 5.44 × 1.6 mm(2920 封装)
  • 品牌:LUTE(陆特)

三、核心性能与优势

  1. 小尺寸高密度:2920 封装相比传统插件型自恢复保险丝占用更小的 PCB 面积,便于高密度设计与自动贴装流程。
  2. 高电流承载能力:最高可承受 40 A 瞬时冲击,保持电流 7 A,满足多种负载启动与短时过载场景。
  3. 可重复自恢复:在过流或过温后器件进入高阻态断开保护,恢复至安全条件后自动降低阻值恢复供电,减少维护与更换频率。
  4. 低导通阻抗:初始态仅 2.5 mΩ,降低功耗与发热,提高系统能效。
  5. 宽温度适应性:-40 ℃ 至 +85 ℃ 的工作温度覆盖车规级与工业级应用需求。
  6. 快速动作:典型动作时间约 6 秒,可在短时间内限制过流,保护下游电路。

四、典型应用场景

  • 汽车电子:车载控制模块、车灯、电动座椅、信息娱乐系统等车用电路的过流/过温保护。
  • 工业控制:PLC 接口、驱动模块、传感器供电保护、通信端口和继电器线圈保护。
  • 消费与便携设备:高电流分配点、充电线路、功率管理模块的安全保护。
  • 其他需高可靠可复位保护的电源路径。

五、安装与使用建议

  • 推荐采用回流焊工艺贴装,遵循厂商提供的回流温度曲线以避免材料应力或性能退化。
  • 在布局上应为器件留足散热通道,尤其在连续高电流工况下,周边铜箔和散热层将有助于降低工作温升。
  • 选型时应根据实际工作电流、峰值冲击及环境温度选择合适的保持电流与跳闸门限,确保既能保护电路又不误动作。
  • 对于关键安全路径建议做冗余设计或配合限流、电流检测电路共同使用。

六、包装与型号说明

2920L700/24GR 为 LUTE 系列标准型号,封装为 2920。请在下单时确认完整型号与参数,以便获取最新的器件数据手册、回流规范及可靠性测试报告。如需样品或量产供货,可联系供应商获取包装、出货周期及认证信息。

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
