MHT192NUGCT 产品概述

一、产品简介

MHT192NUGCT 为 MEIHUA(美华)出品的 0603 封装翠绿色发光二极管,属于无极性 SMT 指示灯类产品。体积小巧、发光均匀,适合高密度电路板指示与小型背光场合,工作温度范围宽,可靠性高,便于自动贴片与回流焊接。

二、主要参数

  • 尺寸/封装:0603(约 1.6 × 0.8 mm SMT)
  • 发光颜色:翠绿色(透镜无色透明)
  • 峰值波长:约 518 nm(出厂规格标注波长范围 520–535 nm,实际光谱以出厂光谱表为准)
  • 发光角度:120°(对称光束)
  • 正向电流(IF):5 mA(额定/典型工作电流)
  • 正向压降(Vf):2.5–3.1 V
  • 发光强度:360 mcd(在规定测试条件下)
  • 功率:75 mW(器件允许的最大功率耗散,请勿长期接近极限)
  • 工作温度:-40 ℃ 至 +85 ℃
  • 极性:无极性(标称无区分正负脚,便于贴装识别与使用)

三、性能与特点

  • 高亮度、色彩纯正:翠绿色发光、峰值接近视觉敏感区,指示效果明显且视觉舒适。
  • 宽视角设计:120° 发光角度,方便面光或侧光的均匀照明。
  • 小封装高密度:0603 规格适合现代便携及消费电子高密度 PCB 设计。
  • 宽工作温度范围,适用环境广:-40 ℃ 至 +85 ℃,可满足一般工业与民用场合需求。
  • 无色透明透镜利于配色和光学设计,不影响波长特性。

四、封装与焊接说明

  • 适用 SMT 自动贴片与回流焊工艺。
  • 建议采用常规无铅回流焊曲线,峰值温度不超过 260 ℃,尽量缩短高温暴露时间以保护发光效率与可靠性;具体曲线请参考锡膏供应商与生产线能力。
  • 存储与搬运时注意防潮、防静电,避免长时间暴露在高湿或强光环境下影响包装与性能。

五、典型应用场景

  • 消费电子指示灯(遥控器、仪表、面板指示)
  • 可穿戴与便携设备的状态指示或背光
  • 智能家居、物联网终端指示
  • 医疗仪器与工业控制小型指示灯(在符合温度与可靠性要求的前提下)

六、设计建议与注意事项

  • 驱动与限流:推荐按额定 IF=5 mA 驱动,限流电阻按公式 R = (VDD − Vf) / IF 计算;例如 5 V 电源、取 Vf≈2.8 V 时,R ≈ 440 Ω(常用 470 Ω)。
  • 功率与热管理:器件功率上限为 75 mW,长时间工作时应留有余量并进行合理散热设计以延长寿命。
  • ESD 与浪涌保护:LED 对静电与瞬态过压敏感,PCB 上应考虑 TVS 或限流保护以及良好接地与静电防护措施。
  • 光学设计:透明透镜在封装层会有出光分布,可根据视角需求配合遮光结构或半透镜设计实现所需指示效果。

七、品质与采购建议

  • 选型时建议索取出厂光谱曲线、典型 IV 曲线与光强测试条件(测试电流、积分光度器角度等),以便在产品设计中精确匹配显示效果。
  • 批量采购前建议进行样品可靠性测试(加速老化、回流焊兼容性、温湿循环)以验证在目标应用环境下的稳定性。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
