MHL3214UBDWT 是美华(MEIHUA)推出的一款高性价比蓝色发光二极管,3mm 圆形插件封装,雾状白色透镜设计,发光波长约 470nm,呈现纯净蓝色光效。适用于状态指示、面板背光、消费电子和各类指示灯等场合,兼具良好的视觉效果与可靠性。
雾状白色透镜能有效扩散点光源,使亮度更加均匀,减少眩光感,适合做指示灯或需要柔和视觉效果的应用。60°的发光角度在保持指向性的同时,也能覆盖较宽视角,配合 3mm 小型灯头适用于面板密集布局。
在常规设计中建议工作电流不超过标称 20mA,以保证器件寿命与稳定性。器件最大耗散能力为 110mW,实际应用时需考虑功耗与散热条件;例如在 20mA、Vf≈3.5V 时,器件功耗约为 70mW,留有余量可提高可靠性。高温环境下应适当降额使用,避免长期满载工作导致光衰或失效。
适用场合包括但不限于:
若需更详细的电光特性曲线、封装尺寸图或可靠性测试报告,可联系供应商或索取完整数据手册以便设计与验证。

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.
