TNXM32768K2NQDCZT2T 贴片晶振产品概述

一、产品核心身份与定位

TNXM32768K2NQDCZT2T是雅晶鑫(YJX) 推出的一款SMD3215-2P封装贴片晶振,核心频率为32.768kHz——这一频率是电子领域的“计时黄金频率”:通过15级2分频可直接得到1Hz(秒脉冲),天然适配各类实时时钟(RTC)、计时单元需求,属于中低端计时场景的高性价比主力型号。

二、关键性能参数的实际价值

1. 频率精度与稳定度

  • 常温频差±20ppm:32.768kHz下,1ppm对应约0.032768Hz,因此±20ppm的偏差仅为±0.655Hz——这个精度足够满足普通消费电子、工业计时的日常需求(比如手表秒误差每天约0.05秒,远低于人眼可感知范围);
  • 频率稳定度±30ppm:覆盖-40℃~+85℃宽温范围时,频率偏差仍控制在±30ppm内(约±0.983Hz),避免了极端温度下计时漂移过大的问题,适合户外设备、工业控制柜等环境。

2. 负载电容与ESR

  • 负载电容7pF:这是32.768kHz贴片晶振的常见匹配规格,与主流MCU(如STM32、ESP32)的内部振荡电路兼容性强,无需额外复杂匹配;
  • 等效串联电阻(ESR)70kΩ:虽不是行业最低,但在32.768kHz频段属于“实用级”——足够维持振荡稳定,且成本更具优势,适合对成本敏感的批量应用。

3. 工作温度与封装适配

  • -40℃~+85℃宽温:覆盖了绝大多数电子设备的工作环境(从北方冬季户外到南方夏季室内,再到工业高温场景);
  • SMD3215-2P封装:尺寸仅3.2mm×1.5mm,厚度约0.8mm,贴片式设计支持自动化贴装,可直接集成到小型化产品(如智能手环、蓝牙耳机、物联网传感器)中,不占用额外空间。

三、典型应用场景

TNXM32768K2NQDCZT2T的参数设计精准匹配以下场景:

  1. 实时时钟(RTC)模块:手机、平板、智能手表的辅助计时(主时钟关机后仍能维持时间);
  2. 智能穿戴设备:手环、手表的计时、闹钟功能(低功耗+小封装适配穿戴的空间限制);
  3. 物联网(IoT)传感器:温湿度传感器、智能门锁的定时上报(宽温稳定+32.768kHz低功耗);
  4. 工业控制单元:PLC、变频器的辅助计时(宽温范围适配工业环境);
  5. 消费电子配件:蓝牙音箱、智能台灯的定时开关(成本优势+稳定性能)。

四、产品优势总结

  1. 精准适配计时需求:32.768kHz频率+合理精度,刚好满足“秒级计时”的核心需求,无需为更高精度(如±1ppm)支付额外成本;
  2. 环境兼容性强:宽温范围+稳定度设计,避免了极端温度下的计时误差;
  3. 小封装高集成:SMD3215封装适合小型化产品,自动化贴装提升生产效率;
  4. 品牌可靠供货稳:雅晶鑫作为国内晶振厂商,产品质量经过市场验证,批量供货周期可控。

该产品是针对“需要精准计时但无需超高端精度”场景的最优解,在消费电子、物联网、工业控制等领域均有广泛落地空间。

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
