2920L1000SL21GRG 聚合物正温度系数自恢复保险丝(PPTC)产品概述

一、产品基本信息

LUTE(陆特)品牌的2920L1000SL21GRG是一款专为低电压、中等功率电路设计的聚合物正温度系数自恢复保险丝(PPTC),核心优势在于过流保护后可自动恢复导通,无需手动更换故障器件。产品采用2920标准贴片封装,兼容自动化贴片生产工艺,适配高密度集成场景(如小型化消费电子、汽车电子)。

二、核心电气参数解读

参数是判断自恢复保险丝适配性的关键,2920L1000SL21GRG的核心参数可支撑多场景应用:

  1. 电压电流耐受:耐压21V,覆盖12V/24V等常见低电压系统;最大电流50A(Imax)可耐受瞬间浪涌(如电源启动峰值);保持电流10A(Ihold)为正常工作的最大稳定电流(未超阈值则不动作);跳闸电流14A(Itrip)是过流保护的临界值,确保故障时及时响应。
  2. 阻抗与功耗:初始态最小阻值1mΩ,导通损耗极低(10A工作时下压降仅10mV),不影响负载效率;跳断后最大阻值5mΩ,处于高阻保护态但非完全开路,避免电路突然断电引发二次故障;正常工作功耗1.5W,适配中等功率电路。
  3. 响应与环境:动作时间5s(跳闸电流下),可过滤瞬间浪涌(如开关瞬间电流),避免误触发;工作温度-40℃~+85℃,覆盖工业、汽车电子等严苛环境温区。

三、关键性能特点

  1. 低损耗导通:1mΩ初始阻值大幅降低电路压降,适合对功率效率敏感的应用(如快充适配器、车载电源),无需额外散热设计。
  2. 自恢复免维护:过流跳断后,待电路温度降至阈值以下自动恢复导通,减少设备停机时间与维护成本,尤其适合无人值守场景(如户外传感器)。
  3. 宽温稳定:-40℃+85℃的工作温区,满足汽车电子(-4085℃)、工业车间(0~70℃)等场景的温度要求,性能无明显衰减。
  4. 小体积高密度:2920封装尺寸(7.98mm×5.44mm×0.8mm),适配小型化产品(如移动电源、智能穿戴),提升电路集成密度。
  5. 浪涌耐受强:50A最大电流耐受能力,可有效应对电源启动浪涌、静电放电(ESD)等突发干扰,保护后端敏感器件。

四、典型应用场景

  1. 汽车电子:车载充电器、中控系统、LED车灯驱动电路(12V系统适配,宽温符合汽车级要求)。
  2. 消费电子:快充适配器(支持10A以上电流传输)、移动电源、智能音箱电源模块(小体积适配便携设计)。
  3. 工业控制:小型PLC、传感器节点、低压电机驱动电路(宽温适应车间环境)。
  4. 通讯设备:路由器、交换机、光模块电源保护(浪涌耐受保障设备稳定运行)。

五、机械尺寸与封装兼容性

产品采用2920贴片封装,具体尺寸为:

  • 长度:7.98mm
  • 宽度:5.44mm
  • 高度:0.8mm

符合国际贴片元件标准,支持回流焊、波峰焊等自动化生产工艺,可与贴片电阻、电容等器件无缝集成,降低电路设计复杂度。

综上,2920L1000SL21GRG凭借低损耗、自恢复、宽温适配等优势,成为低电压中等功率电路过流保护的高性价比选择,覆盖消费电子、汽车、工业等多领域应用。

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
