NCD1803W1 是国星光电推出的一款高可靠性白光表面贴装发光二极管(LED),单颗独立二极管封装,尺寸为超薄 SMD 1.8 × 0.3 mm。该器件以较低的正向电压和适中的光强、宽视角为特点,适用于各种空间受限且需均匀可视指示的场合,如按键指示、仪表面板、可穿戴设备和移动终端等。
这些参数决定了 NCD1803W1 在常规微弱至中等亮度指示应用中的表现,正向压降和功率消耗使其在 3V 左右的供电系统中有良好匹配性。
超薄封装利于减小组件厚度、提升装配密度;145° 的发光角度有利于减少指示盲区,提升可视性。
适用场景包括但不限于:
选型时重点考虑:系统供电电压、可用PCB空间、工作温度范围、预期亮度与寿命要求。若需更高亮度或色温控制,请参考国星光电提供的分档(bin)数据,或选用同系列其他型号。
如需进一步的电气特性曲线、光强随电流/温度的曲线、典型光谱或封装尺寸图(PCB pad 推荐尺寸、回流曲线),可向国星光电或代理渠道索取完整的数据手册以做最终设计定稿。

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.
