SIT1050TK 产品概述
一、产品简介
SIT1050TK（品牌：SIT 芯力特）是一款面向工业与车规级网络的高速 CAN 收发器，支持最高 1 Mbps 数据速率，工作电压范围为 4.5V 至 5.5V，工作温度覆盖 -40℃ 至 +125℃。器件采用 TDFN-8-EP（3×3 mm）小型裸露散热焊盘封装，适合空间受限且需良好散热的应用场景。
二、主要参数
- 类型：CAN 收发器
- 工作电压：4.5V ～ 5.5V
- 数据速率：最高 1 Mbps
- 工作电流（典型）：70 mA
- 静态电流（待机/空闲态）：10 mA
- 工作温度：-40℃ ～ +125℃
- 封装：TDFN-8-EP（3×3 mm，带裸露焊盘）
三、主要特性与优势
- 兼容 1 Mbps 的高速 CAN 网络，满足常见 CAN/CAN FD（单速）通信需求；
- 宽温域设计，适合严苛工业及车载环境；
- 紧凑封装同时带裸露散热焊盘，有利于热管理与高密度 PCB 布局；
- 低静态电流特性可降低待机功耗，70 mA 的工作电流在驱动总线时保持稳定通信；
- 标准接口，便于与主控 MCU、网关或收发模块无缝集成。
四、典型应用场景
- 车载通信模块、车身控制单元（BCM）与网关；
- 工业现场总线、PLC 与运动控制系统；
- 楼宇自动化、安防系统、数据采集节点；
- 电机驱动与传感器网络中需要可靠差分通信的场合。
五、封装与 PCB 设计建议
- 推荐在 VCC 端并联 0.1 µF 陶瓷去耦电容，靠近器件引脚布局；
- 将差分 CAN_H/CAN_L 走线成对且长度匹配，保持差分阻抗（通常 120 Ω）；
- 在总线两端各放置 120 Ω 终端电阻，靠近收发器端布局；
- 使用裸露焊盘（EP）与多层接地平面良好焊接以提升散热性能；
- 在总线入口处建议配置瞬态抑制二极管（TVS）以增强抗浪涌/ESD 能力。
六、可靠性与采购建议
SIT1050TK 针对宽温、工业与车载使用场景进行了设计，建议在批量采购前进行样片评估，包括热性能、EMC 兼容性及长期老化测试。封装小型化有利于系统集成，但对 PCB 焊接和回流曲线有一定要求，请与生产线热工艺调整匹配。购买时确认供货批次与技术支持以确保稳定供应与后续替代件规划。
如需样套电路、封装尺寸图或评估板参考，请告知，我可提供更详细的硬件接入与调试建议。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
