KA-3528SGC 是 Kingbright 推出的超高亮绿光单色表面贴装(SMD)LED,峰值波长为 565 nm,适用于需要醒目绿色指示或背光的电子产品。器件采用小尺寸 SMD-4P 封装(3.5 × 2.8 mm),2 引脚独立二极管结构,透明无色透镜,发光角度宽达 120°,便于面光或散射式照明设计。
该元件在可见光谱中呈现饱和绿光,565 nm 的峰值波长在人眼感知中属于高显色、辨识度高的绿色区域。发光强度范围 12.5~40 mcd 适合指示灯与面光源应用。正向压降约 2.2 V,为常见逻辑/单电池供电系统设计提供便利。请根据应用场景和亮度要求选择合适的驱动电流;常见做法是在限流电阻或恒流驱动下工作,以保证亮度一致并保护 LED 寿命。示例:若使用 5 V 直流电源并以 10 mA 驱动,限流电阻约为 (5 V − 2.2 V) / 10 mA ≈ 280 Ω(仅为示例,实际应按目标电流与热管理要求确定)。
KA-3528SGC 为小型 SMD 封装(3.5 × 2.8 mm),透明透镜使光分布更均匀,适用于贴片生产线的高速贴装与回流焊工艺。器件为卷带(T/R)包装,便于 SMT 自动化装配。由于为独立二极管配置,焊盘与布线时应注意极性标识与焊盘尺寸匹配,避免热应力导致粘接或机械损伤。
总体而言,KA-3528SGC 在体积小、视角宽、绿色显色良好的前提下,适合多种指示与照明场合,是常见的工业与消费类电子产品中的可靠选择。若需更详细的电气表格、光谱曲线或回流焊建议,请参照 Kingbright 数据手册或提供具体应用条件以便进一步评估。

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.
