MHT136CYCT 0402 黄色发光二极管 产品概述

一、主要特性

MHT136CYCT 是 MEIHUA(美华) 推出的超小型 0402 封装黄色发光二极管。该器件以体积小、视角宽、色调稳定为主要特点,适合微型化指示与背景照明场景。透镜为无色透明,发光均匀,适合与光学扩散件配合使用。

二、光电参数

  • 发光颜色:黄色
  • 峰值波长:591 nm(典型)
  • 光谱范围:582.5 nm ~ 594.5 nm
  • 正向压降 (Vf):1.9 V(在典型测试条件下)
  • 正向电流 (If):5 mA(推荐工作电流)
  • 功率(最大耗散):60 mW
  • 发光强度:45 mcd(典型)
  • 发光角度:120°
  • 工作温度范围:-35 ℃ ~ +85 ℃

注:在典型工作电流 5 mA 下,器件耗散功率约为 1.9 V × 5 mA ≈ 9.5 mW,远低于最大额定功率。

三、封装与机械尺寸

封装型号:0402(约 1.0 mm × 0.5 mm)。超小体积适合空间受限的 SMT 应用。由于尺寸极小,贴装与回流焊过程中需严格控制贴装精度与焊膏用量。

四、典型电路与阻值计算

为保证稳定驱动,建议串联限流电阻:

  • 以 3.3 V 电源驱动:R = (3.3 − 1.9) / 0.005 ≈ 280 Ω(可选 270 Ω 或 330 Ω)
  • 以 5 V 电源驱动:R = (5 − 1.9) / 0.005 ≈ 620 Ω(可选 620 Ω 或 680 Ω)
    电阻功率损耗通常很小(例如 5 V 情况下 P ≈ 15.5 mW),普通 1/10 W 或 1/8 W 电阻已足够。

五、装配与回流焊建议

  • 焊膏开窗面积建议遵循 SMT 0402 最佳实践,焊膏量为焊盘面积的约 60% 左右以避免溢胶或虚焊。
  • 回流焊:建议使用无铅回流曲线并遵循焊膏供货商与 IPC 标准,峰值温度一般不超过 260 ℃,加热速率控制在合适范围内,避免长时间高温暴露。
  • 贴装:采用高精度贴装机与合适的吸嘴,防止偏位或倒装。

六、可靠性与存储

  • 处理:为防静电损伤,应在 ESD 防护环境下操作(佩戴腕带、使用防静电台面)。
  • 存储:密封防潮包装,避免潮湿与高温;建议未开封条件下常温干燥保存,开盘后按焊膏厂建议在规定时间内使用,或回潮处理再流焊。
  • 环境耐受:在额定工作温度范围内长期可靠,若用于极端环境(高温、高湿或高冲击),需做额外验证。

七、典型应用场景

  • 移动设备与可穿戴产品的状态指示灯
  • 家用电器与工业设备的面板指示
  • 仪表背光与指示模块
  • 小型照明与光学指示条阵列

八、使用注意与建议

  • 注意极性,0402 封装本体难以直观识别正负极,应参照卷带或出货标识确认。
  • 若需更高亮度或更长寿命,可通过降低驱动电流并改进光学设计(透镜或扩散件)来优化。
  • 在产品开发阶段建议获取样品并进行温升、光衰与寿命试验以验证在目标应用下的表现。

如需器件详细的电光曲线、典型电路图或回流曲线建议,可提供具体需求以便给出更精确的工程建议与设计资料。

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
