YLED1206G(品牌:YONGYUTAI/永裕泰)是一款1206贴片封装的翠绿色发光二极管(LED)。其面向各种通用照明与显示指示应用,体积小、视角宽、光色稳定。主要基础参数如下:
该型号适合用于面板指示、背光、信号指示和消费电子等需要稳定绿色指示的场合。
YLED1206G在525nm附近有峰值发射,色调接近翠绿色,肉眼色彩鲜明。发光强度典型值为620 mcd,配合120°的发光角度,能在较大视角范围内提供均匀可见光。光电性能受工作电流与温度影响,增大电流会提高亮度但同时加速老化并升高结温,从而可能导致光输出随温度升高而下降(需做热管理与电流控制)。
限流电阻计算(基础公式):R = (Vsupply − Vf) / If 示例(以保证不超过20 mA,按最小 Vf = 2.4 V 计算):
限流电阻功率计算:P_R = I^2 × R。以 130 Ω、20 mA 为例,P_R ≈ 0.052 W(推荐使用 1/4 W 或更高功率等级电阻以提高可靠性与散热裕度)。
尽管单个1206 LED散热要求不高,但在高密度封装与长时间点亮场合下要注意结温 (Tj) 的上升。高结温会导致亮度下降、色坐标漂移与寿命缩短。建议:
如需进一步的电气曲线(正向特性、光强随电流/温度的曲线)、色度坐标或回流焊工艺规范,可向厂家索取完整数据手册以便精确设计验证。

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.
