K1206L020YR 产品概述

一、产品简介

K1206L020YR 是一款面向便携式设备与电脑主板的表面贴装复位式过流保护器件(PPTC),采用标准 1206(3216 公制,约 3.2×1.6mm)封装,尺寸为长 3.4mm、宽 1.8mm、高 1.0mm,专为自动化贴片与回流焊流程设计。器件兼容含铅与无铅回流焊,并获得 UL(E352136)、C‑UL(E352136)与 TUV(R50306075)认证,满足 RoHS、REACH、HF 等环保与安全要求,品牌为 KUU。

二、主要电气与机械参数

  • 最大工作电压 (Vmax):24 V
  • 最大短时电流 (Imax):10 A
  • 保持电流 (Ihold):200 mA
  • 跳闸电流 (Itrip):460 mA
  • 跳断后最大阻值 (R1max):2.6 Ω
  • 初始态最小阻值 (Rmin):600 mΩ(0.6 Ω)
  • 最大耗散功率 (Pd):600 mW
  • 动作时间(在指定过流条件下):600 ms
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装尺寸:1206(标注尺寸略高于公制 3216)

三、主要特性与认证

  • 表面贴装(SMD)封装,适合高速贴装与回流焊工艺。
  • 复位型(自恢复)保护:过流移除后可恢复导通,无需更换。
  • 兼容含铅和无铅回流工艺,便于与现有生产线整合。
  • 通过 UL、C‑UL、TUV 等安全认证,满足消费电子与工业应用的可靠性要求。
  • 符合 RoHS / REACH / HF 环保规范,适合全球市场。

四、典型应用场合

  • 手机及便携终端:电池正极及充电端口的短路/过流保护。
  • 数据与充电端口保护:USB、Type‑C、耳机接口等的过流保护与自恢复保护。
  • 电脑主板:即插即用设备(外设/扩展卡)电源防护、热插拔接口保护。
  • 其他低电压直流电源线路的系列过流保护和防短路解决方案。

五、封装与焊接建议

  • 推荐采用标准 1206(3216)贴片工艺,布局时留出稳定的焊盘与散热铜箔以降低接触电阻与热应力。
  • 请遵循芯片制造商提供的回流焊温度曲线(对无铅回流峰值温度通常 ≤ 260 ℃),避免超温或重复高温循环影响器件性能。
  • 贴装时避免强机械应力(例如顶压、弯曲),并注意良好的焊点湿润性以保证低接触电阻。

六、选型与使用注意事项

  • 设定工作电流应低于保持电流 Ihold(200 mA)以避免器件长时间自热;对持续电流更高的应用请选择更高规格的器件。
  • 跳闸电流 Itrip 为 460 mA,通常在正常最大工作电流之上留有裕量;选型时建议工作电流 < Itrip 且考虑启动冲击与脉冲电流对动作的影响。
  • 最大短时电流 Imax=10 A 表示器件能承受短时脉冲或故障性冲击,仍应参考厂商的冲击/脉冲能力曲线进行验证。
  • 注意 Pd=600 mW 表明在高环境温度或受限散热条件下,器件的稳态电阻与动作行为会变化,请参考热降额曲线。

七、可靠性建议与测试

  • 在产品开发验证阶段,建议完成温度循环、冲击、湿热和多次过流触发恢复测试,确认在目标应用环境下的重复动作一致性与阻值变化(初始 Rmin 与跳断后 R1max)。
  • 对于电路布局,优先将器件置于电源入口或端口附近,保证在短路时尽快限制电流并保护后端电路。

综上,K1206L020YR 以其小型化封装、认证齐全与自恢复特性,适合在电池、接口与主板等低压直流系统中担当第一道过流保护。实际应用时请结合完整数据手册与热行为曲线进行详尽验证。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
