TJA1448BT/0Z 是恩智浦(NXP)推出的一款高速 CAN 收发器,用于车用或工业环境下的差分总线通信。该器件支持高达 5 Mbps 的数据速率,工作电压范围为 4.5V 至 5.5V,工作温度覆盖 -40℃ 到 +150℃,适合在严苛环境中实现可靠的 CAN 数据链路。
14-SOIC 封装(0.154",3.90 mm 宽),引脚排列适合常见的微控制器与收发器布局。封装尺寸利于散热与机械强度,便于量产贴片和焊接工艺控制。
在使用时应关注电源去耦、共模干扰抑制以及总线防护措施(瞬态电压抑制器、隔离/滤波等)。针对高温应用,需考虑 PCB 散热设计与长期热应力影响,保证焊点及封装可靠性。建议参考器件数据手册进行典型应用电路与外部保护元件的选型。
作为 NXP 系列高速 CAN 收发器的一员,TJA1448BT/0Z 在车规与工业应用中具有良好兼容性。如需替代或比较,可在同类车规级 CAN 收发器中对比数据速率、工作温度、保护特性和封装尺寸,从而选择更契合系统需求的型号。
如需更详细的电气参数、引脚定义或参考电路,请提供是否需要数据手册或具体应用场景,以便进一步补充。

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.
