TX322516M4FBDE2T贴片晶振产品概述

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。

一、产品核心定位与基本属性

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。

二、关键性能参数详解

(一)频率与频差

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)。

  • 常温频差±10ppm:在25℃环境下,实际输出频率与16MHz的偏差不超过160Hz(16MHz×10ppm=160Hz),可满足多数消费电子的时钟同步精度(如蓝牙低功耗设备的频率偏差要求通常≤20ppm)。

(二)负载电容与起振条件

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。

(三)频率稳定度

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。

(四)等效串联电阻(ESR)

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)。

(五)工作温度范围

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。

三、封装与贴装特性

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。

四、品牌与可靠性说明

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:

  • 高低温循环测试(-40℃~+85℃,循环50次):频率偏差变化≤5ppm;
  • 振动测试(10~2000Hz,加速度1g):无起振异常;
  • 冲击测试(加速度1000g,持续0.5ms):无机械损坏或频率偏移。

五、典型应用领域

该晶振的性能与成本平衡特性,使其广泛应用于以下场景:

  1. 物联网终端设备:低功耗蓝牙(BLE)模块、WiFi模块、ZigBee节点(如智能门锁、环境传感器);
  2. 智能穿戴产品:智能手环、智能手表的时钟模块、心率传感器辅助电路;
  3. 小型家电控制:智能插座、加湿器、扫地机器人的MCU时钟源;
  4. 车载辅助电子:行车记录仪、胎压监测(TPMS)模块、车载蓝牙适配器;
  5. 工业小型模块:小型PLC辅助电路、传感器节点(如温度传感器、压力传感器)。

六、总结

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。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
