国星光电NTD3528I5是一款SMD2835-2P封装的近红外LED,主打中小功率、宽视角、高集成性,核心面向感应、补光类场景的紧凑型设计需求。
其封装尺寸符合行业标准(约2.8mm×3.5mm×0.8mm),2引脚贴片式结构兼容自动化贴装生产线,安装便捷且占用PCB空间极小,适合迷你安防摄像头、小型感应模块等对体积敏感的产品。封装采用耐高温环氧树脂材料,兼顾光学透光性与机械强度,可适配常规回流焊、波峰焊工艺,无需特殊制程要求。
该产品的关键参数直接决定了适用场景,具体特性如下:
结合参数特性,NTD3528I5可适配以下主流场景:
夜间监控摄像头需隐蔽补光,该产品波长在近红外,不干扰画面且无视觉暴露;125°宽视角可覆盖摄像头视野,单颗灯珠即可满足10米内补光需求,降低多灯珠成本。
人体感应开关、自动门传感器、智能灯光控制等场景,12mW/sr辐射强度可穿透薄窗帘、塑料外壳,-40℃~+85℃工作温度适应室内外环境(如阳台感应灯)。
光电开关、物料计数、位置传感器等工业场景,宽视角与稳定辐射强度可实现精准检测,SMD封装适合集成到小型传感器模块(如流水线计数传感器)。
红外遥控器(部分型号)、智能穿戴设备的红外辅助传感(如心率监测),体积小、功耗低的特点符合便携性需求。
国星光电的品牌技术积累让该产品具备以下可靠性优势:
为确保性能稳定,使用时需注意:
NTD3528I5以高性价比、宽适配性成为感应与补光领域的主流选型,适合对体积、成本、可靠性有综合要求的产品设计。

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.
