MHT170JECT 是美华(MEIHUA)推出的一款高性价比红色贴片发光二极管(LED),采用0805 封装(公制 2012,约 2.0 × 1.25 mm),透镜为无色透明型。该器件在小尺寸下提供较宽的发光角与稳定的光输出,适合高密度贴片显示、指示与背光等应用场景。
在典型驱动条件(If = 20 mA、Vf ≈ 2.0 V)下,器件单颗耗散功率约 40 mW(2.0 V × 20 mA)。给出 75 mW 为器件最大耗散限制,长期工作应保证实际损耗低于该值并做好散热与布局。光学输出按出厂测试在 If=20 mA 时测量,存在器件间的公差,实际应用时建议按最小光强规格进行余量设计。
0805 封装适合自动贴装与回流焊工艺。推荐在 PCB 设计时:
为保证稳定工作并延长寿命,应采用恒流驱动或串联限流电阻。举例:
MHT170JECT 作为 0805 标准贴片,通常以带卷(tape & reel)方式供货,便于 SMT 生产线自动贴装。具体包装数量与交期建议直接与供应商/代理确认,以满足批量装配需求。
总结:MHT170JECT(MEIHUA)红色 0805 LED 在微型封装下提供较高的视角与稳定光强,适合要求体积小、指示效果良好的各类电子产品。合理的驱动与热设计可确保其在 -40 ℃ 至 +85 ℃ 工况下稳定长期工作。若需器件详细数据表(包含光电曲线、封装尺寸、回流曲线与可靠性测试数据),建议向美华或代理索取完整 datasheet。

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.
