MHT193CGCT 是美华(MEIHUA)推出的一款高性价比表面贴装发光二极管(SMD LED),采用0603(1608公制)封装,发光颜色为黄绿色(波长569 nm),透镜为无色透明,可实现宽视角、高对比的指示显示。该器件面向消费电子、仪表、通信设备等需要小尺寸、低功耗指示光源的应用场景,兼具稳定的光学输出与良好的可装配性。
MHT193CGCT 的中心波长 569 nm 属于黄绿色区域,视觉敏感度较高,在相同电流下可获得良好的视觉亮度。透镜为透明无色设计,结合 130° 的宽视角,适合面板指示和侧面可见的状态显示。标称发光强度 11.2 mcd 为典型值,通常以 If=5 mA 测试,实际光强会随驱动电流、温度及生产批次略有变化。
电气方面,器件在推荐工作电流 5 mA 下运行,正向压降约 2.2 V。器件标明的功率耗散 60 mW 可用来估算理论上允许的峰值电流(If_max ≈ 60 mW / 2.2 V ≈ 27 mA),但该值为基于功率限值的理论计算,长期工作或频繁脉冲在此电流水平会影响寿命和一致性,因此不建议将其作为常规驱动电流。
LED 驱动方法简单,通常采用限流电阻串联方式:R = (Vcc - Vf) / If。举例:
若需更精确的恒流驱动和亮度一致性控制,可采用小型恒流源或 LED 驱动 IC,特别是在多灯串并联或要求脉冲调光的场合。
总结:MHT193CGCT 以其小型 0603 封装、黄绿色 569 nm 发光与宽视角设计,适合空间受限且要求低功耗指示的各类电子设备。合理的限流与焊接工艺控制可以确保其稳定的光学输出与长期可靠性。若需器件详细电气光学曲线、封装尺寸图或分级信息,建议联系 MEIHUA(美华)或授权代理获取完整规格书与测试数据。

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.
