KP-3216SURCK 是 Kingbright 出品的一款 1206 封装红色 Chip LED,采用无色透明透镜设计。该器件在典型驱动条件下提供稳定的红色光输出,峰值波长 645nm,视觉感知以 630nm 为主,适合各种 SMT 指示与背光应用。工作温度范围宽(-40℃ 至 +85℃),便于工业与消费类环境使用。
上述光学和电气参数均为典型值或额定值,应以厂方完整版规格书为准。常见测试条件为 If=20mA;在该电流下器件耗电约 Vf×If ≈ 2.5V×20mA = 50mW,低于器件最大额定功耗 75mW。发光强度 230mcd 为典型测量结果,实际值会受封装公差、测试设备与驱动条件影响。
1206(公制 3216)封装体积小巧,适合高密度 PCB 布局与自动贴片加工。建议在设计 PCB 着陆图和焊盘时,参照 Kingbright 官方推荐尺寸以保证焊点可靠性与良好的散热路径。采用无色透明透镜,有利于颜色一致性与光学分布。
建议采用恒流驱动或串联限流电阻方式。限流电阻计算示例(以5V电源为例):
R = (Vsource − Vf) / If = (5.0 − 2.5) / 0.02 = 125Ω,选用 120Ω~150Ω 标准阻值;电阻功率 P = I^2×R ≈ 0.05W,常用 1/4W 电阻即可。注意避免长期超过 20mA 连续驱动,若需脉冲加亮应参考厂方脉冲规范并控制占空比与平均功率。
KP-3216SURCK 以其小型 1206 封装、宽视角(140°)与良好的红色发光特性(230mcd@20mA)适合多种指示与背光应用。设计时应关注恒流驱动、热管理与 SMT 工艺,参照 Kingbright 官方规格书以获得最佳可靠性与一致性。需要更详细的机械尺寸、焊盘图与完整电学光学特性时,建议下载或索取厂方数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
