TX322516M4FBDE2T是雅晶鑫(YJX) 推出的一款通用型石英晶体谐振器,采用SMD3225-4P贴片封装,以16MHz为核心标称频率,兼顾性能、体积与成本平衡,适配多数中低端电子设备的时钟同步需求。
该晶振属于4引脚贴片式石英晶体,无需额外外壳,直接通过表面贴装技术(SMT)焊接到PCB板上,具备体积小、贴装效率高的特点。核心定位为“中精度通用时钟源”,既满足消费电子、物联网等领域的常规频率精度要求,又能覆盖-30℃~+85℃的工业级基础温度范围,适合批量生产场景下的成本控制需求。
标称频率为16MHz,是微控制器(MCU)、蓝牙模块等设备的常用时钟频率(如STM32系列MCU默认支持16MHz外部晶振)。
负载电容为12pF,需搭配PCB板上的12pF匹配电容(通常为陶瓷电容),保证晶振起振稳定。若负载电容偏差过大,可能导致起振困难或频率偏移,设计时建议选用精度±5%以内的电容。
全温区频率稳定度为**±30ppm**,覆盖工作温度范围-30℃~+85℃。极端温度下(如-30℃或+85℃),频率偏差最大不超过480Hz,可满足户外设备(如智能门锁)、轻度工业环境(如小型传感器节点)的频率稳定性要求。
ESR为40Ω,属于中等水平。较低的ESR有助于晶振快速起振,减少功耗(ESR越小,起振电流越低),同时降低因电阻发热导致的频率漂移风险,适合自动化生产线的批量贴装(无需频繁调试起振)。
支持**-30℃+85℃**,超过消费级(0℃70℃)的温度范围,可用于部分户外设备(如车载胎压监测模块)或低温环境下的工业辅助设备,无需额外增加温度补偿电路,降低系统成本。
采用SMD3225-4P封装,尺寸约为3.2mm×2.5mm×0.8mm(长×宽×高),体积小巧,可节省PCB板空间,适合小型化产品(如智能手环、无线耳机模块)。4引脚设计符合SMT自动化贴装标准,贴装速度快(约每小时数千片),适合大规模批量生产,有效降低人工成本。
雅晶鑫(YJX)是国内专注石英晶体器件研发与生产的厂商,产品通过ISO9001质量管理体系认证,且符合RoHS环保标准(无铅、无镉等有害物质),可用于出口产品。TX322516M4FBDE2T经过常规可靠性测试:
该晶振的性能与成本平衡特性,使其广泛应用于以下场景:
TX322516M4FBDE2T是一款“高性价比通用贴片晶振”,16MHz核心频率适配多数MCU与通信模块,±10ppm常温频差、±30ppm全温稳定度满足常规精度需求,SMD3225封装适合小型化设计,-30℃~+85℃温度范围覆盖工业级基础场景,雅晶鑫的可靠性保证使其成为批量生产的优选时钟源。
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.
