TAXM12M2GLFBET2T是雅晶鑫(YJX)推出的一款无源贴片石英晶振,针对中低端频率控制需求设计,兼顾性能稳定性与量产成本,广泛适配消费电子、工业控制及通信接口等场景。
该型号隶属于雅晶鑫(YJX)常规商业级晶振产品线,明确为无源贴片类型(无内置驱动电路,需外接振荡电路)。型号后缀“TAXM12M2GLFBET2T”中,“12M”直接对应核心振荡频率12MHz,“SMD”标识贴片封装,符合自动化贴装需求。雅晶鑫作为国内专注石英晶振研发生产的厂商,该系列产品以“高性价比+稳定供货”为核心优势,适合中小批量及量产项目。
基础频率与精度
核心振荡频率为12MHz,是单片机、串口通信等领域的经典频率(如51系列MCU、STM8系列常用12MHz时钟);常温(25℃)频差为**±30ppm**,换算为实际频率偏差为±360Hz(12MHz×30×10^-6),可满足大部分消费电子、工业控制的精度要求(如RS232通信要求频差<50ppm,蓝牙低功耗模块要求<100ppm)。
负载电容与振荡稳定性
负载电容为20pF,无源晶振需外接两个20pF陶瓷电容(分别接于晶振引脚与地之间),电容选型需与该参数匹配——若负载电容偏差过大,会导致振荡频率偏移、甚至停振;等效串联电阻(ESR)为50Ω,属于常规无源晶振的中等水平,可保证振荡裕量,避免温度变化时出现停振问题。
环境稳定性
频率稳定度为**±30ppm**(-20℃+70℃范围内),即温度从-20℃升至+70℃时,频率波动不超过±360Hz;工作温度范围为**-20℃+70℃**,覆盖常规商业级应用场景(如室内设备、一般户外传感器节点),不支持极端低温(如-40℃以下)或高温(+85℃以上)环境。
该型号采用HC-49S-SMD封装,是传统插件HC-49S的贴片化版本,尺寸紧凑(约5.0×3.2×2.0mm),引脚布局兼容部分插件设计,适合自动化贴装(SMT)生产线,可降低人工成本。
电路适配核心注意事项:
总结:TAXM12M2GLFBET2T是一款高性价比无源贴片晶振,以12MHz为核心频率,兼顾精度、成本与量产适配性,适合常规商业级应用场景的频率控制需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
