TJ-L257SSGHKMCGSFLC7K-A5 是 TOGIALED(统佳)推出的一款 5mm 插件式方形发光二极管(LED),提供雾状绿色透镜的普绿光与黄绿色两种发光版本(描述:257雾状绿发普绿光 / 257雾状绿发黄绿光)。外观为方形 5mm 灯头,透镜为雾状绿色,可实现柔和、均匀的出光效果,适合指示、面板显示及装饰等多种应用场景。
产品采用常见的 5mm 插件封装,方形灯头设计便于在面板、指示灯孔或 PCB 上固定和定位。雾状绿色透镜经过漫散处理,光线柔和,降低眩光并提高可视均匀性,适用于近距离观察与长时间指示用途。
该系列在额定 If=20 mA 下工作时,正向压降在 1.8–2.6 V 范围,最大功耗 72 mW,发光强度约 60 mcd,110° 的发光角度带来较宽的视域覆盖。波长集中在 565–575 nm,峰值 575 nm,使人眼对亮度感受更好,黄绿到普绿色调在指示识别上具有良好的辨识度。
适合用于:面板指示灯、仪器仪表、通信设备指示、家用电器面板、交通与标识设备、玩具与装饰照明等需要柔和、均匀黄绿色/绿光指示的领域。
在选型时请确认所需色调(普绿或黄绿)、光强与视角要求,并核对工作环境温度与驱动电流条件。若需更高亮度或封装形式不同的规格,可联系 TOGIALED 获取完整产品系列与快速样品支持。采购时注明完整型号 TJ-L257SSGHKMCGSFLC7K-A5 及所需色调版本,以便准确交付。
本产品设计用于通用工业与消费级应用,工作温度范围 -20 ℃ 至 +80 ℃。如需特定的可靠性测试报告(如寿命、冲击振动、环境应力筛选)或合规认证(如 RoHS、REACH 等),建议向 TOGIALED 或授权代理商索取详细数据手册与检测证明,以满足量产与产品认证需求。

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.
