0805L100/24AR 产品概述
一、产品简介
0805L100/24AR 是陆特（LUTE）推出的一款微小封装自恢复式过流保护器件（PPTC），采用0805封装（尺寸约2.3mm × 1.5mm × 1.2mm）。该器件专为USB端口及便携设备提供过流与过温保护，体积小、响应稳定、经过多次动作后阻值变化率低，适合空间受限、对可靠性有较高要求的消费电子产品。
二、主要特性
- 额定耐压：Vmax = 24V，适用于5V/12V及低压直流系统防护。
- 峰值承受电流：Imax = 40A（短时浪涌承受能力），适应插拔和启动冲击电流。
- 保持电流：Ihold = 1A，在低于此值时保持低阻态；跳闸电流：Itrip = 2A。
- 动作时间：300ms（近似热触发时间，依环境与电流波形会有差异）。
- 功耗/允许耗散：Pd = 800mW。
- 阻值特性：初始态内阻Rmin ≈ 40mΩ；跳断后最大阻值R1max ≤ 270mΩ，恢复后阻值变化率低。
- 工作温度范围：-40℃ ~ +85℃，适应广泛环境。
三、典型应用场景
- USB-A/USB-C/OTG 端口过流与过温保护。
- 移动电源、充电器与车载充电接口（需注意系统电压不超24V）。
- 平板、智能手机、物联网终端、智能穿戴等便携式设备。
- 主板外设接口与消费电子小功率电源保护。
四、设计与布板建议
- 器件应串联在电源或接口供电线上，尽量靠近受保护的端口或连接点布置，以减少受保护区域内的裸露线路。
- 考虑环境温度对保持电流的影响，高温会降低保持电流，必要时选用留有余量的型号。
- 注意Pd 800mW为稳态耗散能力，若长时间处于限流状态应评估温升并留足散热空间。
- 推荐按照0805贴片焊接工艺进行回流焊，避免超过器件温度承受极限。
五、可靠性与注意事项
- 该型号支持多次动作恢复，且动作后阻值回升稳定，适合需要经常短路保护的场合。
- 对于频繁的大电流冲击或高于Imax的情况，器件可能损坏或失效，应通过电路设计限制冲击能量。
- 选择时务必根据实际最大工作电流和可能的冲击电流留足裕量，结合环境温度和散热条件校核可靠性。
六、封装与采购信息
- 封装：0805（2.3mm × 1.5mm × 1.2mm），品牌：LUTE（陆特）。
- 建议按照应用电流选择相应型号，并向供应商确认包装形式（卷带/Reel）和样品可用性。

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.
