MHK43204CGBTD 为 MEIHUA(美华)出品的高显色黄绿色发光二极管,封装为通孔式 DIP-8(针距 2.54mm),透镜为雾状绿色。适合指示、面板显示及通用背光场合,色心接近 568nm(黄绿色),视觉辨识度高,外观柔和不刺眼。
在额定 If=20mA 时 Vf≈2V,为保证稳定工作通常配合限流电阻或恒流驱动。举例:在 5V 驱动下,限流电阻 R=(5V-2V)/20mA≈150Ω。若追求更长寿命与更低发热,建议将工作电流降至 10–15mA 或采用PWM调光。50° 的发散角适用于定向可视指示,若需广角照明需并联多只或改用扩散组件。
DIP-8 通孔结构,便于手工焊接与插装式安装。透镜为雾面,能有效抑制炫光并改善角度均匀性。焊接时注意控温和时间,避免长时间高温直烙,以减少封装与内部键合线应力。安装间距与板孔按 2.54mm 标准处理,便于与标准插座或插件件配合。
综上,MHK43204CGBTD 属于性能稳定、视觉效果良好的黄绿色指示LED,适合多种通用指示与面板照明场合。选型时注意工作电流、热管理与封装安装方式以保证长期可靠性。

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.
