TC77-3.3MCTTR 是美国微芯(Microchip)推出的一款高精度、低功耗的数字温度传感器,封装为 SOT-23-5,适合空间受限和便携式应用。器件通过 SPI 串行接口直接输出数字温度数据,无需外部 ADC 或复杂校准,便于与单片机或嵌入式系统对接。器件工作电压范围宽(2.7V–5.5V),待机电流极低(1 μA),在工业级温度范围(-55℃~+125℃)内可实现 ±1℃ 精度,适合对成本、功耗与精度有综合要求的系统。
TC77-3.3MCTTR 采用 SOT-23-5 小型表贴封装,适合密集 PCB 布局与自动化贴装。该封装在空间受限的工业与消费类产品中具有良好兼容性。实际布局时注意器件的热路径和周边器件发热对测温精度的影响,必要时可做热隔离或采用导热孔/散热策略以获得更准确的环境温度测量。
如需进一步的电气特性曲线、引脚功能、典型时序或参考电路图,我可以基于数据手册为您整理关键信息与布局建议。

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.
