KPTD-3216MGC 产品概述

KPTD-3216MGC 是 Kingbright 旗下 1206(公制 3.2 × 1.6 mm)封装的黄绿色(黄绿)贴片 LED,面向要求中高亮度与窄视角指示/照明应用。器件在典型 20 mA 驱动条件下提供良好的光效与稳定的电气性能,适合消费电子、仪表指示、背光与信号显示等场景。

一、主要技术参数

  • 发光颜色:黄绿色
  • 波长(标称/峰值):570 nm / 574 nm
  • 正向电压 Vf(典型):2.5 V
  • 额定正向电流 If:20 mA
  • 最大耗散功率:75 mW
  • 发光强度(Iop):450 mcd(@ 20 mA)
  • 发光角度:50°
  • 透镜类型:无色透明透镜
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装形式:1206(Kingbright 型号 KPTD-3216MGC)

二、产品特性

  • 紧凑封装适合高密度 PCB 布局,尺寸稳定性好。
  • 黄绿色波段视觉显著,对人眼敏感度高,指示识别性强。
  • 50° 较窄视角便于定向照明和精确指示,减少旁泄光干扰。
  • 无色透明透镜保证光色纯净,便于后续光学配件配合使用。

三、典型应用

  • 面板指示灯、状态指示、按键背光
  • 仪器仪表、医疗设备指示灯
  • 工业控制面板与交通/信号显示
  • 小型指示照明与装饰光源

四、驱动与使用建议

  • 标称驱动:20 mA、Vf≈2.5 V;为延长寿命和降低热应力,可采用 10~15 mA 的降额驱动。
  • 限流电阻计算:R = (Vsup − Vf) / If。示例:5 V 供电,If=20 mA,R ≈ (5−2.5)/0.02 = 125 Ω(常用取 150 Ω);3.3 V 供电,R ≈ (3.3−2.5)/0.02 = 40 Ω(常用取 47 Ω)。
  • 避免长期在最大功率点工作,注意散热与 PCB 铜箔面积以降低结温。

五、封装与焊接建议

  • 1206(3216)体积小,焊接时建议采用回流焊工艺,严格控制温度曲线以防止光学性能退化。
  • 推荐在 PCB 设计中预留适当热沉和通孔/加大焊盘面积以改善散热;焊膏量和焊盘形状应依据厂家推荐进行打样验证。

六、可靠性与储存

  • 工作与存储环境避免高温、高湿、强酸强碱环境;长期储存建议防潮包装(真空或干燥剂)。
  • 建议遵循 ESD 防护规范,避免静电损伤。出厂前请参考 Kingbright 的详细数据手册和焊接曲线进行可靠性验证。

总结:KPTD-3216MGC 在小型化、高识别度指示与点光源应用中表现优秀,结合合理的电流降额与热管理,可在多种产品中实现稳定且长寿命的使用效果。若需更详细的电气/光学曲线或封装图纸,请参考 Kingbright 官方数据手册。

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
