KPT-1608SGC(Kingbright)产品概述

一、产品简介

KPT-1608SGC 是 Kingbright 系列 0603 封装的黄绿色(Yellow-Green)贴片发光二极管,采用透明无色透镜设计,发光均匀、视角宽广。器件适合对体积、功耗与可见亮度有严格要求的便携与消费类电子设备,用于状态指示、面板指示、背光点阵与装饰照明等场景。

二、主要电学与光学参数

  • 发光颜色:黄绿色(主波长 565nm,典型波长 568nm)
  • 正向电压(Vf):典型 2.5 V(If = 20 mA)
  • 额定正向电流(If):20 mA
  • 标称功率:62.5 mW(资料标称)
  • 发光强度:12 mcd(If = 20 mA)
  • 发光角度:120°(半值角)
  • 工作温度范围:-40 ℃ 至 +85 ℃

需注意,按 Vf × If 计算的瞬时电功率约为 50 mW(2.5 V × 0.02 A),资料中标称功率 62.5 mW 时建议在热设计上采用更保守的处理,避免长期在极限条件工作。

三、封装与机械特性

  • 封装型号:0603(等同 1608 公制,典型尺寸约 1.6 mm × 0.8 mm)
  • 透镜:无色透明,便于宽角扩散与良好的色彩还原。
    该封装体积小、适合集成在高密度 PCB 上。建议按 Kingbright 官方资料采用推荐焊盘和过孔布局以保证焊接可靠性与光学对位。

四、散热与可靠性建议

  • 小型 0603 封装散热能力有限,长期满流(20 mA)运行时会产生自热,温升影响亮度与寿命。设计时应考虑热沉或降低平均电流。
  • 在高温环境下建议进行电流降额,例如将工作电流控制在 10–15 mA 以延长寿命与减小热漂移。
  • 建议遵循常规 SMT 回流温度曲线(参考制造商建议),避免超过最大峰值温度和长期高温暴露。
  • 该类 LED 对静电敏感,PCB 装配与测试过程应做好 ESD 防护。

五、典型应用场景

  • 面板与指示灯(电源、状态、告警指示)
  • 可穿戴与便携终端的微型指示与装饰照明
  • 点阵/字符显示背光与信号提示
  • 传感器/模块状态反馈等低功耗照明场景

黄绿色 565–568 nm 接近人眼峰感度波段,单位光强下的主观亮度感知较高,适用于需在弱光环境下提高可见性的指示用途。

六、选型与使用要点

  • 电阻计算示例(以恒流限流电阻为例):
    • 5 V 电源:R = (5.0 − 2.5) / 0.02 = 125 Ω(常用 120 Ω 或 130 Ω)
      限流电阻功耗 Pd = 2.5 V × 0.02 A = 0.05 W,推荐使用 ≥0.125 W 的电阻。
    • 3.3 V 电源:R = (3.3 − 2.5) / 0.02 = 40 Ω(常用 39 Ω)
      Pd = 0.8 V × 0.02 A = 0.016 W,推荐使用 ≥0.063 W 的电阻。
  • 若对寿命与稳定性有更高要求,建议将工作电流降至 10–15 mA,并在实际应用中测量亮度与温升后微调。
  • PCB 设计请参照 Kingbright 官方数据手册的焊盘与回流规范,确保铺铜与焊盘形状兼顾散热与焊接质量。
  • 采购与验收时关注色品坐标、亮度批次一致性与 ESD 包装状态,避免因批次差异影响整机视觉一致性。

总结:KPT-1608SGC 以小体积、黄绿色高视觉效率与宽视角为主要优势,适合密集布局和低功耗指示类产品。合理的电流控制与热管理是确保其长期稳定工作的关键。若需具体焊盘尺寸、回流曲线或色品坐标,请参考 Kingbright 官方数据手册或向供应商索取详细技术支持。

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
