TAXM16M4RDBCCT2T无源贴片晶振产品概述

TAXM16M4RDBCCT2T是雅晶鑫(YJX)推出的一款工业级无源贴片晶振,采用SMD3225-4P小型化封装,核心频率16MHz,具备稳定的频率特性与宽温度适应性,可满足多数MCU、通信模块及工业控制设备的时钟源需求。

一、核心参数总览

该型号晶振的关键参数可分为四大类,具体如下:

  • 基础规格:无源贴片晶振,品牌YJX(雅晶鑫),型号TAXM16M4RDBCCT2T;
  • 频率特性:标称频率16MHz,常温(25℃)频差±10ppm,全温范围频率稳定度±50ppm,负载电容10pF;
  • 电气特性:等效串联电阻(ESR)≤80Ω;
  • 环境参数:工作温度范围-40℃+85℃(工业级),存储温度常规为-55℃+125℃(无源晶振通用范围)。

二、封装与引脚配置

TAXM16M4RDBCCT2T采用SMD3225-4P封装,尺寸为3.2mm×2.5mm×0.8mm(长×宽×高),适配常规SMT生产线,适合对体积敏感的产品设计。
4引脚布局设计为:引脚1/3为谐振端(连接电路的晶振输入/输出脚),引脚2/4为接地/空脚(部分设计中用于增强焊接稳定性,减少机械应力对晶振的影响)。需注意:无源晶振实际工作仅需2个谐振引脚,但4引脚封装可降低焊接后晶振的振动偏移,提升长期可靠性。

三、性能特性解析

  1. 频率精度满足通用需求:常温频差±10ppm对应16MHz下的频偏为160Hz,足以支撑MCU(如STM32、51系列)、蓝牙/WiFi模块的时钟精度要求;
  2. 全温频率稳定度可靠:±50ppm的全温频偏(16MHz下800Hz)覆盖-40℃~+85℃的温度变化,避免极端温度下时钟漂移导致的通信异常或数据错误;
  3. ESR控制在合理范围:80Ω的等效串联电阻处于无源晶振的常规区间,既保证振荡启动速度,又不会因ESR过高导致电路功耗增加;
  4. 负载电容明确易匹配:10pF的负载电容为外围电路匹配提供明确参考,通常需在谐振端外接两个10pF电容(并联到地),即可实现最佳振荡状态。

四、典型应用场景

该晶振因体积小、精度适中、宽温适应,广泛用于以下场景:

  1. 微控制器(MCU)时钟源:各类单片机、嵌入式系统的外部参考时钟(替代内部RC振荡器,提升精度);
  2. 短距离通信模块:蓝牙5.0、WiFi 2.4G、LoRa等低功耗通信模块的参考时钟;
  3. 工业控制设备:PLC、传感器节点、电机控制器等工业级设备的时钟;
  4. 消费电子:智能手表、智能家居网关、便携式医疗设备的时钟模块;
  5. 车载辅助设备:非关键车载单元(如车载蓝牙、胎压监测接收器)的时钟(注:核心车载系统需更高温度范围的晶振)。

五、选型与使用注意事项

  1. 外围匹配电容必须匹配:负载电容10pF,建议外接两个10pF陶瓷电容(0402封装)到地,若电路阻抗偏高可适当调整为15pF;
  2. 焊接工艺要求:无铅回流焊温度峰值不超过260℃,焊接时间≤10秒,避免高温损坏晶振内部石英晶体;
  3. 温度范围适配:若应用环境温度超出-40℃+85℃(如极地或高温车间),需选择宽温(-55℃+125℃)型号;
  4. ESR与驱动能力:确保MCU的晶振驱动端(如STM32的HSE_IN/HSE_OUT)能支持≤100Ω的ESR,该型号80Ω完全适配。

TAXM16M4RDBCCT2T以其稳定的性能、小型化封装及工业级温度范围,成为中低端电子设备时钟源的高性价比选择,尤其适合对体积、成本敏感的量产项目。

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.

Replenishment inquiry Typical RFQ workflow
