KPTD-3216SYCK 产品概述

一、产品简介

KPTD-3216SYCK 是 Kingbright 出品的一款黄色 Chip LED(封装尺寸 1206 / 3.2×1.6mm),顶部为圆顶(Dome)形透镜,透镜为无色透明,发光颜色为纯正黄色。该器件针对指示灯、背光及一般照明提示设计,具有体积小、响应快、色点稳定的特点,适用于对尺寸和亮度有严格要求的消费电子与工业产品。

二、主要规格

  • 发光颜色:黄色(Peak λ = 590 nm)
  • 峰值波长:590 nm
  • 正向电压(Vf):典型 2.5 V(在 If = 20 mA 条件下)
  • 正向电流(If):最大 20 mA(建议日常使用电流请参考下文)
  • 功率(Pd):75 mW
  • 发光强度:800 mcd(在标称测试条件下)
  • 发光角度:35°
  • 透镜颜色:无色透明
  • 工作温度范围:-40 ℃ 至 +85 ℃
  • 封装:1206(3.2 × 1.6 mm),圆顶形光学结构

三、关键特性与优势

  • 小型封装,便于高密度贴片布板,适合窄间距指示与多色阵列设计。
  • 35° 中等窄角发光,提供集中且可视距离良好的指示效果,适合面板指示与信号提示。
  • 透明圆顶透镜可改善出光均匀性并增强视觉亮度。
  • 宽工作温度范围,适应室内外及工业环境的使用要求。
  • Kingbright 品牌保证制造一致性与良好的可靠性支持。

四、典型应用场景

  • 面板指示灯、状态指示、报警指示
  • 键盘背光与功能指示
  • 仪器仪表和通信设备指示
  • 汽车内饰辅助指示(需按车规做额外验证)
  • 消费电子、家电与工业控制面板

五、安装与使用建议

  • 驱动与限流:建议在设计中使用限流电阻或恒流源来稳定正向电流,常见例:5 V 系统下 R ≈ (5.0 − 2.5) / 0.02 ≈ 125 Ω(取 120–150 Ω 标准值);12 V 系统下 R ≈ (12.0 − 2.5) / 0.02 ≈ 475 Ω(取 470–510 Ω 标准值)。
  • 驱动电流:若要求更长寿命或更低功耗,可适当降至 5–10 mA;若需更高亮度,可短时脉冲驱动,但应遵循最大脉冲条件并注意热量管理。
  • 焊接与回流:兼容常规 SMD 回流焊流程,建议按照厂商推荐的回流曲线及焊膏规范操作以避免过热导致光衰或封装损伤。
  • PCB 布局:建议参考 Kingbright 的封装与焊盘推荐布局,保证良好焊接和散热路径,避免热聚集影响寿命与光学性能。

六、热管理与可靠性

  • 器件最大功率为 75 mW,长期满功率运行会增加热应力,应通过降低工作电流或优化 PCB 散热(增加铜箔面积、热过孔等)来控制器件结温。
  • 在高温、高湿或振动环境中,应进行加速寿命试验以验证可靠性。出于长期可靠性考虑,建议在典型应用中不超过标称 If 的 70–80% 进行连续驱动。

七、注意事项与包装信息

  • 存储与防潮:拆带前建议保持干燥包装状态,按湿度敏感等级(MSL)处理并在推荐时间内回流焊接。
  • 静电防护:LED 对静电敏感,操作与包装过程中请采取 ESD 防护措施。
  • 获得最佳性能与兼容性,请在最终设计前查阅并遵循 Kingbright 官方规格书(数据手册)以获取完整的电学、光学曲线、封装图纸与推荐焊盘尺寸。

总结:KPTD-3216SYCK 以其紧凑的 1206 尺寸、稳定的黄色发光(590 nm)与 800 mcd 的亮度,适合各种需要集成小型指示光源的应用。合理的限流、良好的热管理与遵循厂商建议的焊接工艺,能确保在不同应用场景下获得稳定且持久的表现。

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
