MHT155GRCT 为美华(MEIHUA)推出的一款小型贴片双色发光二极管,封装为 SMD-4P,尺寸 3.2×2.7mm,透明无色透镜设计。器件集成红色与黄绿色发光芯片,可用于状态指示、面板指示、背光点亮等需要双色或混色显示的场合。工作温度范围宽 (-40℃ 至 +85℃),适应一般工业与消费类电子环境。
MHT155GRCT 提供明显的双色视觉效果:黄绿色用于高亮度、易辨识的指示,红色用于警示或状态标识。典型发光强度 45 mcd 为 20 mA 驱动下的测量值;若需更长寿命或更低功耗,可采用降流工作(如 5–10 mA),亮度按电流近似线性下降。限流电阻计算公式:R = (Vs − Vf) / If。举例:若 Vs=5 V,取 Vf≈2.0 V,If=20 mA,则 R≈150 Ω,电阻耗散功率 P=(Vs−Vf)×If≈60 mW,应选用额定功率合适的电阻并留有安全裕度。
如需更详细的引脚图、回流焊温度曲线或完整电气参数(最大额定值、波长公差、光强分布曲线等),建议索取 MHT155GRCT 的完整数据手册或联系 MEIHUA 技术支持,以确保在目标应用中获得最佳性能与可靠性。

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.
