KP-2012SYCK — Kingbright 黄光 Chip LED 产品概述

一、产品简介

KP-2012SYCK 是 Kingbright 系列小外形黄色芯片发光二极管,芯片尺寸约为 2.0 × 1.25 mm。发光颜色为黄色,峰值波长与典型波长均为 590 nm,配以无色透明透镜,光束宽广均匀,适合多种指示与背光应用。封装型号具体信息以厂方数据表为准,本概述基于以下基础参数整理。

二、主要特性

  • 发光颜色:黄色(590 nm 峰值)
  • 正向电压(Vf):2.5 V(典型)
  • 额定正向电流:20 mA(典型工作)
  • 功率耗散:75 mW(器件许可最大功率)
  • 发光强度:150 mcd(典型,If=20 mA)
  • 发光角度:120°(宽视角)
  • 透镜颜色:透明(无色)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、电气与光学说明

  • 在典型驱动条件(If = 20 mA)下,KP-2012SYCK 可输出约 150 mcd 的亮度,适用于指示灯与近距背光场合。
  • 按器件允许功率 75 mW 计算,理论最大直流电流约为 75 mW / 2.5 V ≈ 30 mA,但为保证寿命与可靠性,常用驱动电流建议以 20 mA 或更低为主。
  • 发光角度 120° 提供较宽的视场,便于面板指示与大角度可见性需求。

四、驱动与阻值估算(示例)

  • 典型供电 5 V 时,限流电阻 R ≈ (5.0 − 2.5) / 0.02 ≈ 125 Ω,常选 120 Ω 或 150 Ω。
  • 典型供电 3.3 V 时,R ≈ (3.3 − 2.5) / 0.02 ≈ 40 Ω。
  • 实际设计应考虑驱动器容差、温升与并联/串联策略,必要时采用恒流源以稳定亮度与延长寿命。

五、热管理与可靠性要点

  • 器件最大功率 75 mW 为热耗散上限,长时间接近上限会加速光衰与热失配,应保持在安全裕度内。
  • 环境温度接近 +85 ℃ 时,应降低驱动电流以减缓热量积累并维持光输出稳定。
  • 焊接与回流工艺需参考 Kingbright 推荐曲线;若无法获取,建议采用通用无铅回流曲线并避免过长高温暴露。

六、应用场景

  • 仪表与面板指示灯、按钮指示、状态显示;
  • 工业控制面板、家用电器指示、消费电子中的近距背光;
  • 需宽视角、颜色一致性较高的照明指示场合。

七、封装与选型建议

  • 标注尺寸 2.0 × 1.25 mm,适合高密度 SMT 布局;具体 PCB 焊盘与过孔设计请参考官方封装图。
  • 采购时确认 Kingbright 的完整型号与批次数据,若对光强、色容差或潮湿等级(MSL)有特殊要求,应索取完整数据表与可靠性报告。

八、使用注意事项

  • 避免在无限流保护下直接接入电源;启用限流电阻或恒流驱动;
  • 存储与贴片前后防潮处理依赖器件等级(建议按制造商推荐执行);
  • 在高温环境下,应通过降流或增加散热措施保证长期稳定工作。

如需更详细的封装图、回流曲线或光谱分布(光谱曲线、光强随电流/温度的关系),建议向 Kingbright 获取 KP-2012SYCK 的完整数据手册以便精确设计与可靠性评估。

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
