2920L200DR 产品概述
产品概述
2920L200DR是由美国力特（Littelfuse）公司生产的一款聚合物正温度系数（PTC）自恢复保险丝，设计用于提供过流保护，其封装类型为2920（7351公制），其外形为凹陷型，适用于表面贴装。该产品具备一定的热保护特性，能够在过载条件下自动断开电路，并在过载解除后自动恢复，确保设备的安全性及运行的连续性。
基础参数
2920L200DR的工作温度范围为-40°C至85°C，适用于各种工作环境。其最大电压为15V，最大电流可达到40A，保持电流为2A。当电流超出跳断电流（4A）后，该保险丝将在最大动作时间（5秒）内断开电路，避免设备因过载而损坏。同时，其初始电阻值为50mΩ，跳断电阻值最大可达125mΩ，确保在正常工作情况下的低功耗和高效率。
材料与设计
2920L200DR采用聚合物作为主要材料，这一设计使其具有较好的温度稳定性和响应速度。聚合物材料的使用，使得在发生过载时，能够快速地提升其电阻值，切断电流通道，从而保护负载设备。此外，其表面贴装型设计（SMD）使得安装过程更加方便，适合自动化生产线上的批量组装。
应用场景
2920L200DR适用于多种电子设备，例如：
- 消费类电子产品，例如智能手机、平板电脑和家用电器。
- 工业设备中对电流进行保护的应用。
- 汽车电子系统中，保护敏感元件免受过电流损害。
- LED照明系统的过流保护，延长设备的使用寿命。
- 计算机硬件、网络设备等对电流控制 stricter 的应用场景。
性能特点
该产品具有自恢复特性，意味着在过载情况解除后，保险丝能够快速恢复至正常状态，这一特性相较于传统的不可恢复保险丝更具优势，通常意义上减少了设备的维护成本和停机时间。此外，由于其低初始电阻和适当的热管理能力，2920L200DR在设计具有高效率电源管理的应用程序中表现突出。
结语
综上所述，2920L200DR是一款兼具高性能和可靠性的聚合物PTC自恢复保险丝，凭借其宽广的工作温度范围、出色的电流保护特性及方便的表面贴装设计，广泛应用于消费电子、工业设备及汽车电子等领域。用户在选择合适的元器件来保护其设备时，2920L200DR无疑是一个值得推荐的选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
