19-21SYGC/S530-E4/4T 是 EVERLIGHT(台湾亿光)出品的一款高可靠性贴片发光二极管(SMD),封装尺寸为 1.6 x 0.8 mm(常见 0603 类封装)。发光颜色为黄绿色(视觉接近 573 nm),峰值波长 575 nm,适用于空间受限且要求颜色稳定的小型指示与背光应用。
该器件为 SMD 贴片型,尺寸 1.6 x 0.8 mm,透明无色透镜利于颜色纯净与外观一致性。封装适合高速贴装与回流焊工艺,适配微型电子产品的指示灯、面板灯和微型背光。
在选型时建议参考 EVERLIGHT 官方数据手册以获取完整的光学曲线、机械尺寸图、分档(binning)信息及推荐焊接曲线。订购时确认色温/色坐标分档、发光强度等级及封装带卷规格,以便实现批次间一致性。
如需将该器件用于量产,建议先进行样片测试(含热老化、振动与焊接可靠性测试),并依据实际应用对驱动与散热进行优化设计。

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.
