SX3B12.288F1010F30是星通时频(SCTF) 推出的工业级无源贴片晶振,针对中低端通信、工业控制等场景设计,核心定位为「高性价比、宽温稳定的时钟参考源」。其核心特征可总结为:
频率为12.288MHz,是串口通信(9600bps、115200bps)、SPI总线、UART等协议的常用整数倍频率,可避免通信时的时钟偏移问题;常温频差±10ppm(即±122.88Hz),满足单片机、传感器模块的时钟精度要求(一般MCU要求频差≤±20ppm即可稳定通信)。
负载电容为10pF,与SMD3225-4P封装的内部寄生电容(约2~3pF)匹配,无需额外复杂电路设计;封装采用4引脚贴片结构,体积小巧,兼容主流贴片机生产,适合批量应用。
全温范围频率稳定度为**±30ppm**,覆盖-40℃~+85℃温区,可有效抑制极端温度下的频率漂移(如工业现场的低温启动、高温持续运行),避免因频率偏移导致的通信错误或系统卡顿。
ESR为100Ω,低于多数MCU振荡电路的起振阈值(一般≤150Ω即可稳定起振),确保晶振在通电后快速进入稳定振荡状态,减少系统启动延迟。
工作温度为**-40℃~+85℃**,符合工业级温度标准,可用于户外设备、车载辅助系统(非车规级但满足宽温)、智能电表等场景。
SX3B12.288F1010F30因成本与性能平衡,广泛应用于以下领域:
综上,SX3B12.288F1010F30是一款「高性价比、宽温稳定」的无源贴片晶振,适合对成本敏感且需满足工业级温度要求的通信、控制类场景。

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.
