K1210L050YR 产品概述
一、产品简介
K1210L050YR 是 KUU 推出的表面贴装自恢复保险元件（PPTC），采用标准 1210 封装，尺寸紧凑（3.43mm × 2.8mm × 1mm），专为手机、电源管理和电脑主板等空间受限但要求可靠过流保护的场景设计。器件支持自动化贴装与回流焊工艺，兼容含铅与无铅工艺，适用于量产 SMT 组装。
二、主要电气与热性能
- 最高工作耐压(Vmax)：13.2 V
- 最大短时电流(Imax)：40 A
- 保持电流(Ihold)：0.5 A（500 mA）——在此电流下器件保持低阻态
- 跳闸电流(Itrip)：1 A——超过此电流后器件进入限流状态
- 动作时间：约 100 ms（视过流幅度与环境温度而异）
- 功耗（Pd）：600 mW（额定条件下）
- 初始态阻值(Rmin)：≈180 mΩ；跳断后最大阻值(R1max)：900 mΩ
- 工作温度范围：-40 ℃ 至 +85 ℃
三、可靠性与合规
K1210L050YR 已获得 UL（E352136）、C-UL（E352136）与 TUV（R50306076）认证，符合 RoHS、REACH 与 HF（无卤）标准，满足消费电子与工业级安全与环保要求。
四、典型应用与选型建议
适用于手机电源保护、主板电源轨、外设保护及其它需要重复自恢复保护的低压电路。选型要点：
- 常用工作电流应低于 Ihold，避免长期处于热降额区；若电路存在较大启动浪涌，注意浪涌电流是否短时超过 Itrip 导致频繁动作。
- 考虑环境温度影响，温度越高器件越容易触发，关键线路需留有安全余量。
- 若需承受极短时间高幅度脉冲，可评估器件的 Imax 与热冲击能力是否满足要求。
五、封装与工艺建议
标准 1210 封装，适配常规 SMT 贴片工艺。推荐：
- 在 PCB 上靠近电源输入/电池正极处布局以实现快速保护响应。
- 遵循制造商推荐的回流温度曲线（器件兼容含铅和无铅回流工艺），并确保合理的焊盘设计与热通量以利于可靠焊接。
- 避免长期超额电流和频繁触发，以延长器件寿命并保持稳定阻值特性。
总结：K1210L050YR 在小尺寸下提供可靠的自恢复过流保护，认证齐全，适合手机与主板等对体积和自动化组装有较高要求的消费电子应用。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
