TAXM32M4ZDBCCT2T 无源贴片晶振产品概述

一、产品基本属性

TAXM32M4ZDBCCT2T是雅晶鑫(YJX)推出的无源贴片石英晶体谐振器,采用SMD2016-4P封装(尺寸2.0mm×1.6mm,4引脚),属于小型化晶振品类。该型号为无源类型,需配合外部振荡电路(如MCU内置振荡模块)及匹配电容实现稳定振荡,无需额外电源驱动,成本优势明显,适配对体积敏感的电子设备设计。

二、核心性能参数

该晶振的关键参数明确,可满足多数中精度时序需求:

  • 标称频率:32MHz,是微控制器(MCU)、无线模块等领域的常用时钟基准频率;
  • 常温频差:±20ppm,即常温(25℃左右)下频率偏差不超过32MHz×20×10⁻⁶=640Hz,符合消费电子、工业控制的常规精度要求;
  • 负载电容:10pF,为电路匹配的核心参考值(需外接约10pF陶瓷电容至晶振引脚,确保振荡稳定);
  • 频率稳定度:±10ppm,指工作温度范围内频率随温度变化的最大波动,抗温漂能力优于普通晶振,避免极端温度下的时钟偏差;
  • 等效串联电阻(ESR):80Ω,属于无源晶振的常规ESR范围,与多数MCU振荡电路兼容性良好(多数MCU要求ESR≤100Ω),起振可靠性高。

三、工作环境与可靠性

TAXM32M4ZDBCCT2T的工作温度范围为**-40℃~+85℃**,覆盖工业级温度区间,可适应户外、车载等复杂环境下的长期稳定运行;结合±10ppm的频率稳定度,即使在低温(-40℃)或高温(+85℃)下,频率波动仍控制在较小范围,避免因时钟偏差导致的系统异常(如通信丢包、数据同步错误)。

四、典型应用场景

32MHz频率及宽温特性使其适用于多个领域:

  1. 消费电子:智能手环、蓝牙耳机、便携式音箱的MCU时钟源,满足低功耗、小体积需求;
  2. 工业控制:PLC模块、传感器节点、电机控制器的时序基准,抗温漂能力适配车间/户外环境;
  3. 无线通信:蓝牙4.0/5.0模块、低速率Wi-Fi模块的载波参考,确保数据传输稳定性;
  4. 车载电子:车载显示屏、倒车雷达、行车记录仪的时钟源,符合车载级温度要求(-40℃~+85℃)。

五、选型与使用注意事项

为确保晶振性能充分发挥,需注意以下要点:

  1. 负载电容匹配:必须外接两个10pF左右的陶瓷电容(并联于晶振引脚与地之间),电容误差建议≤±5%,否则会导致频率偏差或无法起振;
  2. 焊接工艺:SMD2016封装体积小,焊接时需控制温度(无铅焊接峰值温度≤260℃,焊接时间≤10s),避免热应力导致晶振参数漂移;
  3. 电路布局:晶振引脚应尽量靠近MCU的振荡引脚,减少走线长度,避免电磁干扰(EMI)影响频率稳定性;
  4. 无源vs有源选择:若需简化电路(无需外接电容),可选择有源晶振,但成本更高;TAXM32M4ZDBCCT2T作为无源晶振,成本优势明显,适合已有振荡电路的方案。

该晶振凭借小型化、宽温稳定、成本可控等特点,成为消费电子、工业控制、车载电子等领域的实用选型。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
