2920L1200SL21GRG 过流保护器件产品概述

一、产品核心身份与应用定位

2920L1200SL21GRG是LUTE(陆特)品牌2920封装自恢复过流保护器件(PPTC),专为小体积、中等功率密度的电路设计,核心功能是在过流事件中自动切断电路,故障排除后无需手动干预即可恢复导通,兼具可靠性与经济性。其定位覆盖消费电子、汽车电子、工业控制等多领域,尤其适配对空间紧凑性、宽温适应性要求高的场景。

二、关键电性能参数深度解析

该器件参数经过严格校准,直接关联实际保护效果,核心参数意义如下:

  1. 耐压(Vmax=21V):器件正常工作/保护状态下可承受的最大直流/交流电压,超过可能导致绝缘失效,需匹配电路工作电压不超过此限值。
  2. 最大电流(Imax=50A):跳断前可承受的瞬间最大电流(非持续),反映抗浪涌能力,可应对电路突发短时间大电流冲击。
  3. 保持电流(Ihold=12A):常温(25℃)下持续导通不动作的最大电流,是电路匹配的核心依据(正常工作电流需≤12A)。
  4. 跳闸电流(Itrip=14A):常温下5秒内触发保护的最小电流,明确过流阈值——电流超14A时,器件快速进入高阻态切断过流路径。
  5. 消耗功率(Pd=1.5W):持续工作允许的最大耗散功率,需结合电路电压电流计算,避免过热损坏。
  6. 初始态阻值(Rmin=1mΩ):常温最小导通电阻,远低于常规过流器件(如熔断丝多为几十mΩ),显著降低导通损耗,提升设备能效。
  7. 跳断后阻值(R1max=3mΩ):保护后高阻态最大阻值,有效限制故障电流;故障排除后阻值恢复至初始低阻水平。

三、封装与物理特性

采用2920表面贴装封装,尺寸为2.9mm(长)×2.0mm(宽),符合国际标准,适配自动化贴装生产线,可节省电路板空间。封装材料耐温性、机械强度优异,支持回流焊工艺,且符合RoHS、REACH等环保指令,满足全球市场合规要求。

四、环境适应性能力

工作温度范围为**-40℃~+85℃**,覆盖多数场景温度波动:

  • 低温场景:北方户外设备、车载冬季工况下(-40℃),电性能稳定无失效;
  • 高温场景:设备内部散热空间小、夏季户外工况下(+85℃),仍能正常触发保护,阻值变化在允许范围内。
    此外,器件具备抗振动、抗冲击能力,可适应汽车行驶振动、工业设备机械冲击等场景。

五、典型应用场景示例

结合参数特性,典型应用包括:

  1. 消费电子:智能手机/平板电池保护、USB Type-C接口过流保护、智能穿戴设备电源模块保护;
  2. 汽车电子:车载小功率控制模块(车窗/座椅调节)、传感器电路(胎压监测)、车载USB充电口保护;
  3. 工业控制:小型PLC I/O口保护、低压直流驱动电路(小型电机/电磁阀)保护;
  4. 通信设备:小型基站PDU过流保护、路由器/交换机端口保护。

六、产品优势总结

2920L1200SL21GRG核心优势为:低导通损耗(1mΩ初始阻值)、宽温适应(-40℃~+85℃)、小体积封装(2920)、自恢复功能(无需更换),可提升电路可靠性、降低维护成本,是中等功率电路过流保护的高性价比选择。

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
