产品概述：1210L050YR 聚合物-PTC-自恢复保险丝
一、概述
1210L050YR 是由美国力特（Littelfuse）生产的一款聚合物过热保护自恢复保险丝（PTC，Positive Temperature Coefficient），旨在针对多种电子应用提供过流保护。此款保险丝特别适用于需要耐高温、体积小巧的电子设备其在过载情况下能够有效地保护电路，确保设备的长期稳定运行。
二、产品特性
工作温度范围：1210L050YR 的工作温度范围为 -40°C 至 85°C，能够适应各种严苛的环境条件，保证在极端温度下也依然能够正常工作。
电压和电流特性：
- 最大电压：该保险丝的最大电压为 13.2V，适合多个低电压电路应用。
- 最大电流：最大允许通过电流为 100A，能够有效应对高功率需求的电路。
- 保持电流（Ih）：在常规工作条件下允许的最大持久电流为 500mA，保证正常工作状态下不会跳断。
- 跳断电流（It）：1A 的跳断电流，意味着在电流过高情况下，保险丝会快速切断电路，避免了设备因过流而损坏。
电阻特性：
- 初始电阻（Ri）：初始电阻值为 250mΩ，确保保险丝在正常情况下允许通过相应电流。
- 跳断后电阻（R1）：最大跳断后电阻值为 900mΩ，保证在过流情况下能够有效保护电路并且能够快速恢复。
反应时间：最大动作时间不超过 50ms。此迅速的反应时间使得该保险丝可以在电流异常瞬间迅速跳断，保护后续电路。
封装与安装：采用表面贴装型（SMD）封装，尺寸为 1210（3225 公制），其长宽为 0.127" x 0.102"（3.22mm x 2.58mm），厚度最大为 0.033"（0.85mm），这个小巧的设计使其能够在各种紧凑型电路板中轻松安装，节省空间，便于大规模生产。
材料类型：使用聚合物材料生产，具有良好的热稳定性和自恢复能力，适合在较长时间内运行在最大容许工作条件下。
三、应用场景
1210L050YR 聚合物 PTC 自恢复保险丝特别适用于以下领域：
- 消费电子设备：如智能手机、平板电脑和便携式音响等，防止由于过流导致的电路短路与损坏。
- 电池管理系统：提供电流保护，确保电池在充电和放电过程中的安全使用。
- 电源供应设备：保护电源电路，以防过流对电源变换器和整流器造成损害。
- 汽车电子：用于汽车电气系统中，防止因过流对车载电子设备造成影响。
四、总结
1210L050YR 聚合物-PTC-自恢复保险丝以其优良的电气特性和宽广的应用范围，在现代电子设备中扮演着关键角色。凭借高可靠性和方便的表面贴装设计，Littelfuse 制造的该款保险丝在不断变化的市场需求中，能够有效确保设备安全与稳定运作。选择 1210L050YR，不仅是对电路安全的确保，更是对高科技电子产品长期稳定性的信任。

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.
