PCA82C250M/TR(华冠 HGSEMI)是一款面向汽车与工业现场总线的高性能CAN收发器,支持1 Mbps 数据速率,工作电压范围为4.5V至5.5V。器件工作温度范围宽广(-40℃至+125℃),适合苛刻环境下的可靠通信需求。该型号采用SOP-8封装,便于表面贴装与批量生产。
PCA82C250M/TR提供差分发送与接收功能,将逻辑层的TXD信号转换为差分CANH/CANL总线电平,并将总线信号恢复为RXD输出。器件具备总线驱动能力,可在长链路与多节点环境下保证信号完整性与抗干扰性。内部通常集成短路保护与温度保护机制,提高系统稳健性。
在产品验证阶段,建议进行:高/低温循环测试、ESD与瞬态抑制测试、总线短路/过压测试以及长时间稳定性运行测试。注意在高工作电流(典型78 mA)条件下评估PCB热散与周边器件发热,防止临近器件受热影响。
总结:PCA82C250M/TR具备汽车级温度范围、1 Mbps高速数据率与低静态电流等优势,适用于对可靠性与抗干扰性有较高要求的CAN总线节点。在设计时遵循供电去耦、总线终端与良好布局等通用准则,可充分发挥其性能,提升系统稳定性。

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.
