2920L150/60GR 产品概述

一、产品简介

2920L150/60GR 是 LUTE(陆特)推出的一款小型表面贴装自恢复保险器(PTC),采用 2920 封装,专为高电压、大电流场合的过流及过温保护而设计。与传统插件式自恢复保险丝相比,该产品占用空间小、响应可靠,适合汽车电子及工业控制等对体积和可靠性有较高要求的应用场景。

二、主要电气参数

  • 最大耐压 (Vmax):60 V
  • 最大电流 (Imax):15 A
  • 保持电流 (Ihold):1.5 A
  • 跳闸电流 (Itrip):3 A
  • 消耗功率 (Pd):2.5 W
  • 初始态阻值 (Rmin):35 mΩ
  • 跳断后阻值 (R1max):230 mΩ
  • 动作时间:约 2 s(在规定过流条件下)
  • 工作温度:-40 ℃ ~ +85 ℃

三、机械与封装信息

  • 封装:2920(SMD)
  • 外形尺寸:长度 7.98 mm,宽度 5.44 mm,高度 2.1 mm
    该封装便于自动贴装与回流焊接,适合集成到紧凑型 PCB 设计中,节省占板面积同时保持良好散热和可靠性。

四、产品特性与优势

  • 小体积高密度:相比传统插件式器件,2920 封装显著节省 PCB 占用面积。
  • 高压大电流能力:60 V 耐压与 15 A 峰值能力,可满足汽车电源及工业电源接口的要求。
  • 可自恢复保护:在过流条件消除后器件能自动恢复导通,减少维护与成本。
  • 可预测的保护行为:明确的保持电流、跳闸电流与动作时间,便于设计时的保护阈值设定。
  • 宽温度范围:-40 ℃ 至 +85 ℃,适用于严苛环境下长期工作。

五、典型应用场景

  • 汽车电子:车载控制模块、传感器供电保护、车载充电/点烟器接口防护。
  • 工业控制:PLC I/O 端口、电源模块、工业通信接口保护。
  • 电源与充电:电池管理系统(BMS)外部保护、适配器与充电口防短路。
  • 消费与嵌入式设备:USB/电源接口、外接模块的过流保护。

六、设计与选型建议

  • 保持电流选择:Ihold 应大于正常工作最大电流,避免误动作;本器件 Ihold=1.5 A,适用于标称工作电流不超过此值的回路。
  • 跳闸灵敏度:Itrip=3 A,适合用于需要在较低过流门限下实现保护的场景。
  • 热环境影响:工作温度与 PCB 布局会影响动作特性,高温环境下器件更易触发,设计时应留有裕量并考虑散热。
  • 与其他保护元件配合:对于高能短路或一次性故障,可与慢熔断或直接熔断保险丝配合使用,以提高整体系统保护能力。
  • 布局建议:靠近被保护端口或连接器放置,缩短电流环路,提高响应速度并降低对系统的影响。

七、可靠性与使用注意

  • 在额定条件下器件具有长期稳定性;跳闸后内部阻值上升(R1max=230 mΩ),应在故障消除后确认电路能恢复到期望工作状态。
  • 适用于标准 SMD 贴片与回流工艺,但在焊接与回流过程中应遵循厂商推荐的工艺规范以保证性能(建议参照 LUTE 官方资料进行具体工艺控制)。
  • 存储与搬运需防潮防震,避免超温或长期暴露于有腐蚀性气体环境。

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
