KPT-1608SYCK 产品概述

一、产品简介

KPT-1608SYCK 是 Kingbright 推出的一款黄光贴片芯片型 LED(SMD,1608/0603 尺寸规格)。该器件采用透明无色透镜,发射明显的黄色光(峰值波长 590nm),在指示、状态显示与小功率照明等场合具有良好的可视性与互换性。器件小巧、亮度稳定、视角较大,适合集成于高密度电路板与便携电子设备中。

二、主要参数(概要)

  • 发光颜色:黄色
  • 峰值波长:590 nm
  • 正向压降(Vf,典型):2.6 V
  • 额定正向电流:20 mA(最大/标称)
  • 最大功率耗散:75 mW
  • 光强(Iv,典型):150 mcd(If = 20 mA)
  • 发光角度:120°
  • 透镜颜色:无色透明
  • 工作温度范围:-40 ℃~ +85 ℃
  • 封装形式:SMD(1608 / 0603)
  • 品牌:Kingbright

三、电学与光学性能分析

  • 正向压降:典型 Vf = 2.6 V,在实际电路中应以此为参考并根据温度系数对 Vf 做小幅调整(温度升高时 Vf 会略降)。
  • 驱动电流:20 mA 为常见测试与最大额定值,若追求更长寿命与更低功耗,可在 10–15 mA 或更低电流下使用;在脉冲驱动时需遵循制造商关于峰值电流与占空比的限制。
  • 光强与观感:150 mcd(If = 20 mA)在 120° 的宽视角下提供均匀可视的黄色指示光,透明透镜有助于获得纯净的色温与较少的光学衰减。
  • 功率与散热:器件最大功率耗散为 75 mW,在高环境温度或密集贴装情况下需注意散热与额定电流的降额。

四、封装与贴装建议

  • 封装:1608(公制 1.6 mm × 0.8 mm,常称 0603),适合自动贴片与回流焊工艺。
  • 焊接:建议按 Kingbright 官方数据表或行业标准(例如 J-STD-020)执行回流焊曲线;避免在超出推荐峰值温度和时间的情况下回流以免影响光学性能和可靠性。
  • PCB 布局:参考厂商推荐的焊盘尺寸以保证良好焊接强度与光轴位置;在高密度区域可考虑增加铜面积或通过散热结构改善热管理。
  • 静电防护:LED 可能对静电和瞬态过压敏感,贴装与测试环节建议采取 ESD 管理(穿戴防静电手环、使用防静电工作台等)。

五、典型应用场景

  • 面板与设备状态指示(电源、充电、工作状态等)
  • 消费电子与便携设备指示灯
  • 仪器仪表与工控面板的可视指示
  • 小面积背光或装饰照明(低功率场合)

六、实用建议与注意事项

  • 驱动方式:建议采用恒流驱动或在串联限流电阻的恒压电源中精确计算限流电阻。
  • 寿命与可靠性:长期工作建议对正向电流适当降额并注意环境温度,避免持续在最高额定功率下工作以延长使用寿命。
  • 颜色一致性:批次间存在色容差,若系统对色差敏感,应与供应商确认 binning 信息并按需下单同一色级批次。
  • 环境与法规:若用于消费类产品,关注相关 RoHS 等合规要求并向供应商确认材料合规性。

七、典型驱动与计算示例

  • 以 3.3 V 电源驱动(If = 20 mA):限流电阻 R = (3.3 V − 2.6 V) / 0.02 A ≈ 35 Ω;电阻功耗 P_R ≈ 0.02 A × 0.7 V ≈ 14 mW。
  • 以 5 V 电源驱动(If = 20 mA):限流电阻 R = (5 V − 2.6 V) / 0.02 A ≈ 120 Ω;电阻功耗 P_R ≈ 0.02 A × 2.4 V = 48 mW。
    上述计算以典型 Vf = 2.6 V 为基准,实际设计应留有裕量并考虑 Vf 的分布与温度影响。

总结:KPT-1608SYCK 是一款小尺寸、高可视性且易于批量贴装的黄色 SMD 指示芯片 LED,适合多种指示与小功率显示应用。为确保最佳性能与寿命,应参考 Kingbright 官方数据表进行最终设计、焊接工艺与环境适配。

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
