KPTR-3216SYCK 为 Kingbright 出品的反向贴装黄色发光二极管(Reverse Mount LED),采用 1206(3216)封装设计。发光颜色为黄色,峰值波长 590nm,透镜为无色透明,发光角度宽达 140°,适用于需要广角指示或背照式导光应用的电子设备。工作温度范围 -40℃ 至 +85℃,可满足工业级温度要求。
KPTR-3216SYCK 属于 1206(3216)SMD 规格,采用反向贴装结构(Reverse Mount),即发光面朝向 PCB 板面或特定导光结构的一侧设计,便于采用背光、键盘指示或通过光导槽传输光线的低矮结构。SMD 封装利于自动贴装与回流焊流程,需按制造商推荐的焊盘尺寸与回流工艺参数进行焊接以保证可靠性。
在产品开发与量产前,建议进行温度漂移、光强随时间衰减、焊接耐受性及振动/冲击测试,验证在目标应用环境下的稳定性。对长期使用场景,应考虑在高温或高湿环境下的降额策略与防护措施。
如需进一步的封装图、焊盘推荐尺寸或完整电光特性曲线(I-V、光强-电流、光强-角度等),可联系供应商或参考 Kingbright 数据手册以获得原厂详细资料。

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.
