TXM30M0004252LBCEO00T是雅晶鑫(YJX)推出的一款高频贴片石英晶振,针对工业控制、通信及小型化电子设备的时钟信号需求设计,具备宽温适应性、低ESR及稳定频率输出等特点,以下从多维度详细介绍。
该晶振属于SMD封装石英谐振器,核心功能是提供30MHz精准时钟信号,适用于需要稳定时序参考的电子系统。作为雅晶鑫的中端性能产品线成员,其设计兼顾了小型化、可靠性与成本控制,可替代同规格进口晶振,满足国内多数电子设备的量产需求。
基准频率为30MHz,常温(25℃±2℃)下频差控制在**±10ppm**,换算为实际频率偏差约±300Hz(30MHz×10×10⁻⁶)。该精度满足工业控制、消费电子等领域的常规时序要求,可避免因频率偏差导致的通信丢包、控制指令延迟等问题。
ESR为35Ω,属于该封装(SMD2520)下的低阻水平。低ESR意味着晶振起振速度更快、工作功耗更低,同时抗干扰能力更强,适合对功耗敏感的小型设备(如智能穿戴)及对起振稳定性要求高的场景(如工业传感器)。
采用SMD2520-4P封装,尺寸约为2.5mm×2.0mm×0.8mm(英制2520对应公制尺寸),4引脚贴片结构,支持自动化贴装(SMT),可显著节省PCB空间,适配小型化、高密度布局的电子设备。
该晶振的工作温度范围为-40℃~+85℃,属于工业级温度标准,可适应严寒(如北方户外设备)、高温(如车间控制柜)等恶劣环境。此外,贴片封装的抗振动性能优于直插封装,能承受一定程度的机械振动(如工业流水线设备的振动),无需额外的减振措施即可稳定工作。
雅晶鑫(YJX)作为国内石英晶振领域的专业厂商,具备完整的研发、生产与测试体系:
综上,TXM30M0004252LBCEO00T贴片晶振以其稳定的频率输出、宽温适应性及小型化封装,成为工业控制、通信及消费电子领域的高性价比选择,可满足多数中端电子设备的时钟信号需求。

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.
