XC53M4-12.288-F18LJDT是杭晶电子(HCI)推出的工业级小型贴片晶振,采用SMD5032-4P封装(5.0×3.2mm规格),标称频率12.288MHz——这是串口通信(UART)、音频采样等场景的常用基准频率。产品针对宽温环境下的稳定时钟输出需求设计,覆盖-40℃至+85℃的工业级温度范围,可适配工业控制、消费电子、车载等多领域的中高端应用,兼具小型化与高可靠性特点。
标称频率为12.288MHz,常温频差±20ppm(百万分之一),换算后实际频率误差≤±245.76Hz,满足大多数数字电路对时钟精度的基本要求;温度频率稳定度±30ppm,即使在极端工作温度(-40℃~+85℃)下,频率偏差也控制在≤±368.64Hz,确保设备在不同环境下的时钟同步一致性,避免因频率漂移导致的通信异常或功能失效。
配置18pF负载电容,适配主流MCU(如STM32系列)、ASIC等芯片的内置振荡电路匹配需求,无需额外复杂的外部电容设计,简化PCB布局;等效串联电阻(ESR)60Ω,平衡了振荡启动速度与功耗:低ESR可降低电路功耗,同时保证晶振在通电后快速进入稳定振荡状态,避免启动延迟问题。
支持**-40℃~+85℃**的工业级温度范围,覆盖户外设备、车载控制器、工业PLC等场景的环境温度变化,无需额外的温度补偿电路即可实现稳定输出,降低系统设计成本与复杂度。
采用SMD5032-4P贴片封装,尺寸仅5.0×3.2×1.3mm(典型厚度),适合高密度PCB设计(如小型化路由器、智能传感器模块),4引脚布局便于焊接与电路匹配;杭晶电子采用气密性陶瓷封装工艺,有效隔离外界湿度、灰尘对晶振的影响,提升长期可靠性;同时符合RoHS环保标准,适配全球市场的环保要求,焊接兼容性良好(支持回流焊、波峰焊),生产效率高。
适配PLC可编程逻辑控制器、工业传感器模块、伺服驱动器等设备,宽温范围可应对工厂车间的温度波动,12.288MHz频率满足工业总线(如Modbus)的通信时钟需求,保证数据传输的准确性。
应用于机顶盒、智能路由器、网络摄像头等设备,12.288MHz是UART串口通信的常用基准频率,可实现设备间的稳定数据交互;小型封装适合消费电子的紧凑设计,提升产品集成度。
可作为车载控制器(如车身控制模块BCM)的辅助时钟源,宽温范围适配车载环境的高温(夏季车内)与低温(冬季户外)变化,满足车载电子的可靠性要求。
用于小型无线基站、蓝牙模块、Wi-Fi模块等,12.288MHz频率可作为射频电路的参考时钟,保证信号的频率稳定性,提升通信质量。
该产品通过平衡精度、温度适应性与小型化,成为多领域时钟同步场景的高性价比选择,可直接替换同规格竞品,降低研发与采购成本。

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.
