TPXD32768K2CGCAZT2S 32.768kHz直插晶振产品概述

TPXD32768K2CGCAZT2S是雅晶鑫(YJX)推出的一款32.768kHz低频石英晶体谐振器,采用直插DT-38封装,主打高时间精度、低功耗特性,适配对计时基准要求稳定的各类电子设备,是消费电子、MCU系统、小型工业控制等领域的常规时间基准器件。

一、产品核心定位

该晶振聚焦低功耗计时场景,以32.768kHz(2¹⁵Hz)标准频率为核心,天然适配分频得到1Hz(秒信号),无需复杂电路即可实现精准计时。不同于高频晶振(如12MHz、24MHz),其功耗更低、抗干扰性更强,尤其适合对电池续航敏感的便携设备或长期运行的嵌入式系统。

二、关键性能参数解析

1. 频率与精度特性

  • 标准频率32.768kHz:行业通用计时基准,广泛应用于实时时钟(RTC)、MCU低速外部晶振(LSE)等场景,分频电路简单(仅需15级二分频即可得到1Hz)。
  • 常温频差±15ppm:在25℃(常温)下,频率偏差为32.768kHz×15e⁻⁶=±0.49152Hz,即每日时间偏差约为±42.5秒,满足大多数民用计时需求(如电子钟表、闹钟)。
  • 频率稳定度±30ppm:覆盖工作温度范围(-10℃~+60℃)内的频率变化,即温度波动时最大偏差为±0.98304Hz,适配日常室内外轻量温度变化场景(如空调环境、小型家电)。

2. 电气与匹配参数

  • 负载电容12.5pF:晶振工作需外接两个匹配电容(一般为12pF~15pF,并联后总负载接近12.5pF),直接影响起振稳定性和频率精度,需与电路设计严格匹配。
  • 等效串联电阻(ESR)30kΩ:低频晶振的合理ESR范围,确保电路起振容易,同时低功耗特性明显(ESR越低,功耗越低,适配低功耗MCU)。

三、封装与环境适应性

  • DT-38直插封装:引脚间距符合标准,支持手工焊接或波峰焊,安装便捷;封装尺寸紧凑(约3.8×1.5mm),适配小型PCB板(如智能手环、闹钟主板)。
  • 工作温度范围-10℃~+60℃:覆盖日常使用的温度区间(如室内常温、小型家电工作温度),不支持极端高温/低温,但满足大多数民用/轻量工业场景。
  • 防护性:DT-38封装多为塑料/金属材质,可有效防护机械损伤、轻微电磁干扰,确保晶振长期稳定运行(MTBF可达10万小时以上)。

四、品牌与品质保障

雅晶鑫(YJX)是国内专注于石英晶体谐振器的专业厂家,TPXD32768K2CGCAZT2S经过老化测试、温度循环测试、振动测试等可靠性验证,符合IEC 60368等行业标准。其ESR、频差等关键参数在生产过程中严格管控,批量产品一致性好,适合量产应用。

五、典型应用场景

  1. 消费电子:电子钟表、闹钟、智能手环/手表的RTC计时模块(低功耗特性适配电池续航);
  2. MCU/单片机系统:STM32、ATmega等MCU的LSE晶振(替代内部RC,提升计时精度10倍以上);
  3. 小型工业设备:工业控制器的定时功能、传感器节点的时间同步(如温湿度传感器数据时间戳);
  4. 低功耗通讯:蓝牙低功耗(BLE)设备的时间基准(BLE对时间精度要求较高,该晶振可满足)。

总结:TPXD32768K2CGCAZT2S是一款性价比高、稳定性强的32.768kHz直插晶振,适配多场景计时需求,是电子设计中常规时间基准的可靠选择。

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
