1206L050/15YR 产品概述
产品简介
1206L050/15YR 是一款由美国力特（Littelfuse）公司推出的聚合物自恢复保险丝，属于表面贴装（SMD）元器件系列。这种高性能的保护器件专为在电压高达 15V、最大电流可达 100A 的应用场合中提供过电流保护而设计。其采用的聚合物材料，具有良好的热稳定性和机械强度，确保在恶劣环境下可靠运行。
关键参数
- 工作温度范围：-40°C ~ 85°C，使其适用于多种工业、通信和汽车电子应用，需考虑高温和低温环境的影响。
- 最大额定电压：15V，适合大多数低压电子设备。
- 最大电流：100A，提供强大的过流承载能力。
- 保持电流（Ih）：最大 500mA，确保在正常工作条件下，器件能够长时间稳定工作。
- 跳断电流（It）：1A，明确指示保险丝何时会切断电路，保护后续电路和设备的安全。
- 跳断时间：最大 100ms，迅速响应过电流，防止系统损坏。
- 初始电阻值（Ri）：最低 150mΩ，确保电流的优化传导以及热量的最小化。
- 跳断后电阻值（R1）：最高 750mΩ，显示出这款保险丝在过流后仍能保持的一定导电能力。
封装与尺寸
1206L050/15YR产品采用了常用的 1206（3216 公制）封装，具备凹陷结构。这种设计使其能够容易地安装在多种 PCB 板上，便利于自动化贴装。其实际尺寸为 0.126” 长 x 0.065” 宽（约 3.20mm x 1.65mm），厚度最大为 0.030”（0.75mm），适合各种紧凑型电子设备。
应用领域
由于其优越的性能和多样的工作环境适应性，1206L050/15YR 自恢复保险丝广泛应用于多种领域：
- 消费电子产品：如手机、平板、笔记本电脑等，保障电源部分及数据传输部分在过流情况下的安全。
- 汽车电子：在电动车、乘用车及商用车各类电气系统中，保护电池管理系统及其他电气组件。
- 工业设备：在各种控制器、传感器和驱动器中，保持系统的稳定性和可靠性。
- 通信设备：如基站和网络设备中，保护信号完整性和电源部分免受过流损害。
优点与特性
- 自恢复性：与传统的保险丝不同，PTC（正温度系数）器件在产生过电流后不会彻底断路，而是可在问题解决后自动恢复，省去了替换保险丝的麻烦，提升了系统的可靠性和可维护性。
- 快速响应：它能够在短时间内检测过流并快速反应，极大地提高了系统保护的即时性。
- 长寿命和可靠性：聚合物材料的特性虽然能承受多次过电流，但其耐用性也能延长设备整体使用寿命。
总结
Littelfuse 的 1206L050/15YR 聚合物自恢复保险丝是一款高效可靠的电流保护组件，适合多种现代电子应用的需求。无论是在日常消费电子产品、严苛的汽车环境，还是在复杂的工业系统中，它都展现出了卓越的性能和价值，是保护设备安全、延长其使用寿命的理想选择。

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.
