NCD3220S1是国星光电(国内LED及光电元件领域龙头企业)推出的小型化表面贴装(SMD)光电接收器件,聚焦“宽光谱响应+低噪声+紧凑封装”核心特性,适配消费电子、工业控制、智能家居等领域对“小体积、高灵敏度、宽温适应性”的光电检测需求。作为国星光电光电元件产品线的基础款之一,该器件依托企业在封装工艺、材料研发上的积累,具备稳定的性能表现与可靠的工业级品质。
NCD3220S1的频谱范围为400nm~1100nm,完整覆盖可见光(400-760nm)与近红外(760-1100nm)波段,可兼容多种光源(如白光、红外LED、自然光等)的检测,无需额外滤波即可实现多场景下的光电信号采集,降低系统设计复杂度。
器件暗电流典型值为20nA,属于同类SMD光电接收器件中的低噪声水平。暗电流是无光照时的本征电流,低暗电流意味着在弱光环境下,信号电流与噪声电流的比值(信噪比)更高,可有效避免“误判”或“信号丢失”,提升检测精度。
接收角度为60°,兼顾空间覆盖范围与灵敏度平衡:既能够检测一定角度范围内的入射光(避免仅针对正前方的“窄视角”限制),又不会因角度过宽导致灵敏度衰减,适合需要“区域检测”而非“点检测”的场景(如环境光感应、小型物体识别)。
NCD3220S1采用SMD(表面贴装)封装,尺寸3.2mm×2mm,属于超小型封装规格:
结合性能特性,NCD3220S1可广泛应用于以下场景:
为确保器件性能稳定,使用时需注意以下要点:
Request for quote
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.
