K0805L010AR 产品概述
一、产品简介
K0805L010AR 是 KUU 品牌的一款表面贴装自恢复熔断器（PTC/Polyfuse）/过流保护器件，采用标准 0805（毫米）封装，体积小、外形低矮，专为移动设备与计算机主板等空间受限的电子产品设计。器件兼容含铅与无铅回流焊工艺，适合自动化贴装和批量生产。
二、主要电气参数
- 额定耐压（Vmax）：15 V
- 最大可耐受电流（Imax）：100 A（峰值短路能力）
- 保持电流（Ihold）：100 mA
- 跳闸电流（Itrip）：300 mA
- 跳闸动作时间：1.5 s（在规定过流条件下）
- 功率耗散（Pd）：500 mW
- 初始态电阻（Rmin）：1 Ω（典型初始低阻）
- 跳断后最大电阻（R1max）：7.5 Ω
- 工作温度范围：-40 ℃ ~ +85 ℃
三、外形与封装
- 尺寸：长 2.3 mm × 宽 1.5 mm × 高 0.95 mm（符合 0805 毫米封装规范）
- 封装形式：表面贴装（SMD），适用于自动贴片机与回流焊流程。
四、特性与优势
- 小尺寸、低剖面，适合高密度布局与便携式终端。
- 可逆自恢复：在过流解除后可自动恢复导通，避免频繁更换器件。
- 通过 UL（E352136）、C-UL（E352136）、TUV（R50306074）认证，并符合 RoHS、REACH 与 HF（无卤）环境标准。
- 与常见贴片工艺兼容，便于批量 SMT 生产。
五、典型应用与设计要点
- 适用：手机（分支电源、充电线路保护）、电脑主板（外设接口、低压子电源）、便携式设备的电源输入与信号保护等。
- 设计建议：器件应靠近需保护的输入/输出端放置，以减少导线/走线上的能量积累；在设计时注意器件的 Pd 与工作温度，避免长期高载流导致误动作或老化。
- 注意事项：避免在超过额定电压或长期超过 Ihold 的条件下使用；若系统存在持续高能短路，仍需搭配熔断器或其他过流保护措施。
六、焊接与可靠性建议
- 推荐采用标准回流焊曲线，器件已通过含铅和无铅回流工艺兼容性测试。
- 储存与回流前避免潮湿环境，必要时按贴片元件干燥包装要求预烘。
- 裸板布局应考虑散热与温升，避免与高发热元件紧邻。
七、认证与合规
K0805L010AR 已通过 UL、C-UL、TUV 认证，并满足 RoHS、REACH、HF 等环保和安全规范，适合商用消费电子产品的可靠性与合规性要求。
总结：K0805L010AR 为高密度、低剖面、认证齐全的表贴自恢复过流保护器件，适合移动终端与主板类产品中对空间、工艺与可靠性有较高要求的电源保护应用。购买与替换时请核对具体工作电流、功率和布板条件，确保整体保护方案可靠。

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.
