产品概述：1206L035/16YR 聚合物 PTC 自恢复保险丝
一、产品简介
1206L035/16YR 是 Littelfuse（美国力特）公司推出的一款聚合物 PTC（正温度系数）自恢复保险丝，专为提供过流保护而设计。该保险丝采用表面贴装封装型号，符合 1206（3216 公制）尺寸标准，具有良好的电气性能和耐环境性，适合在多种应用场合下使用。其工作温度范围为 -40°C 到 85°C，使其能够在极端环境中正常工作。
二、主要规格
- 工作温度: -40°C 至 85°C
- 最大工作电压: 16V
- 最大电流: 100A
- 保持电流 (Ih): 350mA（最大值）
- 跳断电流 (It): 750mA
- 跳断电阻值: 1.2Ω（最大值）
- 初始电阻值: 300mΩ（最小值）
- 最大动作时间: 100ms
- 封装类型: 1206（3216 公制），凹陷
- 尺寸: 3.20mm x 1.65mm x 0.75mm（长 x 宽 x 厚）
三、功能和工作原理
聚合物 PTC 自恢复保险丝利用聚合物材料的特点，能够在过流情况下提供有效的保护。当电流超过设定的跳断电流（750mA）时，保险丝内的电阻会显著增加，快速限制通过的电流，从而保护下游电路。当故障消除后，设备会逐渐恢复到正常工作状态，此时保险丝内的电阻会降低，电流可以再次流动。
与传统的玻璃保险丝相比，1206L035/16YR 具备自恢复的优点，意味着在设备没有进行更换的情况下，用户可以快速恢复设备的正常运行，降低维护成本和停机时间。
四、应用场景
1206L035/16YR 聚合物 PTC 自恢复保险丝广泛应用于电子设备的过流保护，尤其是以下几种场景：
- 消费电子: 如智能手机、平板电脑、笔记本电脑等个人电子产品。
- 家电: 冰箱、洗衣机、微波炉等家用电器的过流保护。
- 汽车电子: 汽车音响、导航系统等汽车用电子设备。
- 网络设备: 路由器、交换机等网络配件的保护。
- 医疗器械: 医疗设备中的电源保护。
五、安装与使用
该产品采用表面贴装技术（SMD），易于在自动化生产线上进行安装，减少了人工操作时间，适合大规模生产。安装时应遵循相关焊接规范，以确保良好的电连接与散热性能。同时，设计电路时应考虑到电流参数与保险丝的额定值，以便提供最佳的保护效果。
六、总结
1206L035/16YR 聚合物 PTC 自恢复保险丝是一个高效、可靠的过流保护解决方案，结合了优异的电学特性与适应各种工作环境的功能，能够为多种电子产品提供关键的安全保障。随着消费电子和智能化设备的日益普及，自恢复保险丝在现代电子设计中的重要性愈加凸显，是电子设计工程师的理想选择。

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.
