NTD3528U4 是国星光电推出的一款高功率紫外(UV-A)3528 封装发光二极管,峰值波长集中在 365–370nm 范围,专为紫外照明、固化与检测类应用设计。该型号在窄谱带、较高辐射功率和紧凑封装之间取得平衡,适合需要稳定紫外辐照的工业与实验室场景。
NTD3528U4 的峰值波长集中在 365–370nm,属于紫外-A 波段,半波宽仅 10.5nm,意味着输出光谱相对集中,利于针对性激发或固化光敏材料(例如荧光染料、光敏树脂、荧光检测试剂等)。130° 的较大发光角度适合对面积较大或近场照明需求,不适合需要高度聚光的小角度远距照明场景。
总结:NTD3528U4 在 3528 SMD 封装下提供了高辐射功率、窄谱峰值和宽出光角的紫外输出,适合多种固化、检测与激发类应用。合理的恒流驱动与有效的热管理是确保器件稳定可靠运行的关键;在系统设计中同时要重视紫外安全与 ESD 防护。若需进一步的电光-热特性曲线、可靠性测试数据或封装尺寸图,请参考国星光电的详细产品资料或联系厂家技术支持。

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.
