2920L300/36GR 产品概述
一、产品简介
2920L300/36GR 是陆特（LUTE）推出的一款表面贴装型自恢复保险元件（PTC resettable fuse），采用2920封装，体积小巧但具备高电压和大电流承受能力。相比传统插件式自恢复保险丝，该系列在占用空间、热耦合和可靠性方面更适合车规与工控端口的过流、过温保护设计。
二、关键性能参数
- 耐压（Vmax）：36 V
- 最大电流（Imax）：40 A（短时允许通过电流，具体请参考应用环境与浪涌曲线）
- 保持电流（Ihold）：3 A（在规定环境温度下持续通过而不动作的最大电流）
- 跳闸电流（Itrip）：5 A（典型动作电流，超过此值将进入高阻态）
- 消耗功率（Pd）：2 W（最大稳态功耗）
- 初始态电阻（Rmin）：12 mΩ（冷态低阻，系统压降小）
- 跳断后电阻（R1max）：48 mΩ（动作后限流电阻）
- 动作时间：20 s（在指定过流条件下的典型动作时间）
- 工作温度：-40 ℃ ~ +85 ℃
- 外形尺寸：长 7.98 mm × 宽 5.44 mm × 高 1.6 mm
- 封装：2920（SMD）
- 品牌：LUTE（陆特）
三、主要特性与优势
- 小体积、高密度：2920 封装相比传统插件件显著减小PCB占用面积，利于产品小型化与自动化贴装制造。
- 低初始电阻：12 mΩ 的低导通电阻可减少正常工作状态下的功耗与发热，适合电源总线与高电流分支。
- 快速自恢复：过流时进入高阻态限制电流，故障解除后可自动复位，无需更换元件，降低维护成本。
- 宽温范围与车规适配：支持-40~85 ℃ 工作环境，适合车载与工业控制等复杂工况。
- 高电压与大电流能力：36 V 耐压与短时 40 A 承受能力满足多种高能场景需求。
四、典型应用场景
- 汽车电子：车载通信模块、车门控制单元、传感器供电保护等端口过流防护。
- 工业控制：PLC I/O 接口、电源分配总线与驱动模块的回路保护。
- 消费与嵌入式设备：电源管理、充电接口及输出保护等场景。
五、设计与使用建议
- 布局与散热：贴片时尽量留有周边铜箔以利散热，避免将元件完全包围在高热源附近。
- 选型余量：长期工作电流建议低于 Ihold，留有裕量以应对温升与环境变化。
- 浪涌管理：针对大电流浪涌场合，应配合限流器件或软启动电路，避免频繁动作影响寿命。
- 焊接与可靠性：使用符合组件规格的回流工艺，避免过高焊接温度或长时间热冲击。
六、可靠性与维护
2920L300/36GR 具有较高的循环动作寿命，但频繁在临界电流附近动作会加速老化。建议在设计阶段进行热仿真与寿命评估，并在必要时通过增加裕量或使用并联方案降低单元负担。

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.
