MHT170UBCT(0805)产品概述

一、产品简介

MHT170UBCT 是美华(MEIHUA)出品的一款高亮蓝色贴片发光二极管(LED),采用常见的 0805 小型封装,透明无色透镜,发光颜色为蓝色,峰值波长468 nm,光谱范围 460–475 nm。器件适用于各种指示灯、面板背光及微小光源场合,兼顾体积小、视角宽和工业级温度范围。

二、主要参数

  • 型号:MHT170UBCT(0805)
  • 封装:0805 SMD(2.0 × 1.25 mm 级别)
  • 峰值波长:468 nm(典型)
  • 波长范围:460–475 nm
  • 发光颜色:蓝色
  • 正向电流(If):20 mA(最大)
  • 正向压降(Vf):约 3.3 V(If = 20 mA)
  • 最大功率耗散:95 mW(器件额定)
  • 发光强度:225 mcd(典型标称值,测量条件见厂家资料)
  • 发光角度:140°(半角视场较宽)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 透镜:无色透明

注:光学与电气数值通常与测量电流、温度和测试条件相关,设计时请参考厂方完整数据手册。

三、性能特点

  1. 小尺寸、低剖面:0805 封装便于高密度 PCB 布局与自动贴装生产。
  2. 宽半角发光:140° 的发光角度适合指示和泛光需求,视场更均匀。
  3. 蓝光稳定:峰值 468 nm,色温与色点稳定,适合需要一致色彩的应用。
  4. 工业级温度:-40 ℃ 至 +85 ℃ 的工作范围,满足多数工业及消费类环境。
  5. 透明透镜:无色透镜对颜色纯度影响小,有利于光束控制与配色设计。

四、焊接与可靠性建议

  • 驱动与限流:器件最大正向电流为 20 mA,推荐设计工作电流视寿命要求通常取 5–15 mA。限流电阻按 R = (Vsup − Vf) / If 计算,并留有余量以抵抗电压波动。
  • 功率与热管理:典型电耗 Vf×If ≈ 3.3 V × 20 mA = 66 mW,器件最大额定功率 95 mW。在高密度布板或高环境温度下注意散热与退让。
  • 回流焊建议:遵循厂家回流曲线与 IPC 标准,避免过高峰值温度和长时间高温浸泡以防光效退化。一般建议预热阶段、恒温浸焊和短时间峰值加热(参考数据手册)。
  • ESD 与搬运:LED 对静电敏感,建议在无静电环境或采取接地、防静电手腕带与导电包装下操作。
  • 存储与湿敏级别:如为潮湿敏感器件(MSL),需按规定干燥处理和及时回流焊接,防止吸湿返修。

五、典型应用场景

  • 面板指示灯与信号指示(家电、仪表、通信设备)
  • 小型背光与按键指示(便携电子、遥控器)
  • 工业控制与状态显示(继电器指示、指示板)
  • 玩具与装饰照明(要求小型、高亮蓝色光源场合)

六、选型与工程注意事项

  • 若需更高亮度或更大功率,请考虑更大封装或多颗并联方案,并注意热设计。
  • 在严格色彩匹配的系统中,应基于供应商的波长/色坐标分 bin 选择与测试。
  • 对于汽车级或高可靠性应用,应验证是否通过相应认证或选择专用汽车级产品。
  • 设计前请索取并阅读完整版数据手册(IV 曲线、光强-电流曲线、热阻等),以便进行精准仿真与匹配。

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
