2512L200/33GR产品概述

一、产品基本信息

2512L200/33GR是LUTE(陆特)品牌推出的一款2512封装过流保护器件,属于自恢复型过流保护元件范畴。该产品针对低压高电流场景设计,兼具高电流承载能力与低损耗特性,适配自动化贴装工艺,广泛应用于电源、电机、汽车电子等领域。

二、核心电气参数详解

产品核心参数明确了其工作边界与性能指标,关键参数及意义如下:

  • 耐压(Vmax):33V
    器件可长期承受的最大工作电压,适用于12V、24V等低压直流电路(如车载、工业电源系统),避免电压击穿风险。
  • 最大电流(Imax):50A
    正常导通状态下的长期最大承载电流,支持大功率负载(如小型直流电机、高功率LED模组)的稳定工作。
  • 保持电流(Ihold):2A
    环境温度范围内维持导通的最大电流,即电路正常工作电流需≤2A(避免误触发保护)。
  • 跳闸电流(Itrip):4A
    触发断开动作的最小电流,当电路电流≥4A时,器件会在规定时间内跳断,阻断过流。
  • 动作时间:3s
    电流达到跳闸电流时的响应时间,兼顾瞬态浪涌耐受(如电机启动峰值电流)与故障快速保护(负载持续过流时3s内断开)。
  • 初始态阻值(Rmin):20mΩ
    导通状态下的最小电阻,低阻值可大幅降低电路损耗(如电源传输线损耗),提升系统效率。
  • 跳断后阻值(R1max):120mΩ
    故障断开后保持的最大电阻,确保故障状态下有效阻断电流,避免后端器件损坏。
  • 消耗功率(Pd):2W
    正常工作时的最大允许功耗,反映器件发热控制能力,长期工作无过热风险。

三、关键性能特性

  1. 高电流密度:Imax达50A,在2512小封装内实现大功率承载,适配高密度PCB布局;
  2. 低损耗设计:初始阻值仅20mΩ,比同封装普通过流器件低30%以上,减少电路功率消耗;
  3. 稳定动作特性:Ihold/Itrip比例为1:2,动作时间精准(3s),无“过灵敏”误动作或“保护滞后”问题;
  4. 宽温适应性:工作温度覆盖-40℃~+85℃,满足工业、汽车等极端温度场景(如北方冬季车载系统);
  5. 自恢复功能:故障排除后可自动恢复导通,无需手动更换,降低维护成本。

四、典型应用场景

该产品针对低压高电流过流保护需求,典型应用包括:

  1. 电源系统:12V/24V直流电源模块、LED驱动电源、安防监控电源的输出过流保护;
  2. 电池管理(BMS):电动车、储能电池组的单体电池过流保护,防止过充过放导致的电池损坏;
  3. 电机驱动:小型直流电机、步进电机的堵转保护(如打印机、智能家居电机);
  4. 汽车电子:车载音响、车灯、传感器电路的过流保护,适配汽车-40℃~+85℃工作环境;
  5. 消费电子:笔记本电脑、移动电源的输出端保护,提升产品可靠性(如短路时快速断开)。

五、封装与物理尺寸

采用2512标准贴片封装(行业通用尺寸),具体物理参数:

  • 长度:6.85mm
  • 宽度:3.3mm
  • 高度:1.2mm

封装符合IPC-J-STD-020标准,支持自动化贴装(回流焊、波峰焊),生产兼容性好,适合批量制造。

六、可靠性与环境要求

产品通过以下可靠性测试(常规工业级标准):

  • 温度循环测试(-40℃~+85℃,循环500次);
  • 湿热测试(85℃/85%RH,1000h);
  • 振动测试(10~2000Hz,加速度2g)。

存储环境建议:温度-55℃~+125℃,湿度≤60%RH,避免腐蚀性气体接触。

该产品以高性价比、稳定性能适配多场景低压过流保护需求,是提升电路可靠性的理想选择。

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
