TAXD32768K2BGACZT2T 32.768kHz直插晶振产品概述

一、产品基本定位与核心属性

TAXD32768K2BGACZT2T是雅晶鑫(YJX)推出的直插式石英晶体振荡器,核心频率为32.768kHz——这一频率因与2¹⁵(32768)的整数关系,天然适配数字电路的分频需求(如快速得到1Hz计时基准),是实时时钟(RTC)、单片机低速时钟等场景的经典选型。产品采用DT-26标准直插封装,无需复杂贴片设备即可安装,兼顾性能与生产便利性,覆盖消费电子、工业控制、通信等多领域应用。

二、关键性能指标深度解析

(一)频率精度与环境稳定性

  • 常温频差±5ppm:常温(25℃左右)下,晶振输出频率与标称值的偏差不超过±5×10⁻⁶。以32.768kHz为例,单秒频率偏差约0.16384Hz,换算成年误差约5.2分钟,可满足电子钟、智能手表等日常计时的精度需求;
  • 全温区频率稳定度±10ppm:覆盖-40℃~+85℃宽温范围时,频率漂移控制在±10ppm内。即使在极端环境(如北方冬季户外、工业高温车间),仍能保持稳定输出,避免温度变化导致的计时偏差或电路失步。

(二)负载电容与起振可靠性

  • 负载电容12.5pF:晶振工作需外接匹配电容形成谐振回路,该型号的负载电容为12.5pF。实际电路中通常采用两个6pF或12pF电容串联(总电容接近12.5pF)并联到晶振两端,若匹配电容偏差过大(如超过±1pF),可能导致频率精度下降或无法起振,需注意电路设计中的电容选型;
  • 等效串联电阻(ESR)40kΩ:ESR是晶振谐振时的内阻,直接影响起振难易程度。该型号ESR为40kΩ,属于32.768kHz晶振的常规合理范围,配合单片机/RTC芯片的内部振荡电路(如反相器)即可稳定起振,无需额外增加驱动电路。

(三)工作温度与环境适应性

  • -40℃~+85℃宽温范围:远超普通消费级晶振(0℃~70℃)的温区覆盖,适合户外设备(如智能路灯、环境监测节点)、工业PLC、车载辅助系统等对温度要求严格的场景,无需额外温控措施即可稳定工作。

三、封装形式与典型应用场景

(一)DT-26直插封装特点

TAXD32768K2BGACZT2T采用DT-26标准直插封装,引脚间距符合行业规范,可通过手工焊接、波峰焊等方式安装,无需专用贴片设备,降低了中小批量生产的成本与门槛。封装尺寸紧凑,适配各类小型化电路设计。

(二)核心应用场景

  1. 实时时钟(RTC)模块:作为DS1302、PCF8563、DS3231等RTC芯片的时钟源,提供精准秒级计时基准,支持设备断电后的时间保持;
  2. 单片机低速时钟:适配8051、STM8等8位单片机的外部低速晶振输入,经分频后得到1MHz以下工作频率,降低系统功耗;
  3. 工业控制设备:PLC、传感器节点、工业仪表等需要稳定计时与同步的场景,宽温特性适配现场复杂环境;
  4. 消费电子:电子钟、智能手表、智能家居设备(如智能门锁)的计时功能;
  5. 通信模块:低速率无线通信(如LoRa、ZigBee)的同步时钟,保证数据收发的时序一致性。

四、品牌与可靠性保障

雅晶鑫(YJX)作为国内专注于石英晶振研发的企业,TAXD32768K2BGACZT2T经过高低温循环、振动冲击、湿度老化等可靠性测试,确保批量产品的参数一致性与长期稳定性。产品符合RoHS环保标准,可满足出口与绿色制造需求,适合量产项目的稳定供货。

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
