KP-3216SURCK 产品概述

一、产品简介

KP-3216SURCK 是 Kingbright 出品的一款 1206 封装红色 Chip LED,采用无色透明透镜设计。该器件在典型驱动条件下提供稳定的红色光输出,峰值波长 645nm,视觉感知以 630nm 为主,适合各种 SMT 指示与背光应用。工作温度范围宽(-40℃ 至 +85℃),便于工业与消费类环境使用。

二、主要性能特点

  • 发光颜色:红色(Dominant wavelength 630nm,Peak 645nm)
  • 正向压降(Vf):2.5V(典型,If=20mA)
  • 正向电流(If):20mA(建议连续工作电流)
  • 最大功率耗散:75mW(器件最大额定功率)
  • 发光强度:230mcd(典型,测试条件 If=20mA)
  • 发光角度:140°(宽视角,适合大视野指示)
  • 透镜:无色透明
  • 工作温度:-40℃ ~ +85℃
  • 封装:1206(3216公制尺寸,适用于标准 SMT 贴装)

三、光电参数与测试条件

上述光学和电气参数均为典型值或额定值,应以厂方完整版规格书为准。常见测试条件为 If=20mA;在该电流下器件耗电约 Vf×If ≈ 2.5V×20mA = 50mW,低于器件最大额定功耗 75mW。发光强度 230mcd 为典型测量结果,实际值会受封装公差、测试设备与驱动条件影响。

四、封装与机械特性

1206(公制 3216)封装体积小巧,适合高密度 PCB 布局与自动贴片加工。建议在设计 PCB 着陆图和焊盘时,参照 Kingbright 官方推荐尺寸以保证焊点可靠性与良好的散热路径。采用无色透明透镜,有利于颜色一致性与光学分布。

五、典型应用场景

  • 面板与设备状态指示灯
  • 键盘/按键背光与符号背光
  • 消费电子指示与指示条
  • 小型信号与装置指示(工控、仪表)
  • 一般照明点亮特征或装饰性照明

六、驱动与设计建议

建议采用恒流驱动或串联限流电阻方式。限流电阻计算示例(以5V电源为例):
R = (Vsource − Vf) / If = (5.0 − 2.5) / 0.02 = 125Ω,选用 120Ω~150Ω 标准阻值;电阻功率 P = I^2×R ≈ 0.05W,常用 1/4W 电阻即可。注意避免长期超过 20mA 连续驱动,若需脉冲加亮应参考厂方脉冲规范并控制占空比与平均功率。

七、制造与可靠性建议

  • SMT 回流焊:遵循 Kingbright 推荐的回流温度曲线与工艺参数,避免过高峰值温度和重复热循环。
  • 防静电与搬运:LED 对 ESD 敏感,建议在 ESD 保护环境下搬运与装配。
  • 储存与湿度管理:如器件有防潮等级要求,应按包装说明进行干燥箱管理或回流前烘烤处理。
  • 环境与寿命:在额定温度与电流条件下使用可获得长期稳定性能,极端高温或过流会加速衰减。

八、总结

KP-3216SURCK 以其小型 1206 封装、宽视角(140°)与良好的红色发光特性(230mcd@20mA)适合多种指示与背光应用。设计时应关注恒流驱动、热管理与 SMT 工艺,参照 Kingbright 官方规格书以获得最佳可靠性与一致性。需要更详细的机械尺寸、焊盘图与完整电学光学特性时,建议下载或索取厂方数据手册。

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
