TFOM32768K4RHKCNT2T 32.768kHz时钟晶振产品概述

TFOM32768K4RHKCNT2T是雅晶鑫(YJX)推出的一款工业级32.768kHz高精度时钟晶振,采用SMD3225-4P贴片封装,具备宽电压兼容、稳定温度适应性等核心优势,可广泛应用于实时时钟(RTC)、低功耗物联网终端等场景,满足不同电子设备对精准时钟基准的需求。

一、核心参数与产品定位

该产品聚焦低功耗精准时钟基准需求,核心参数明确且适配主流应用:

  • 基准频率:32.768kHz(2^15分频可直接得到1Hz,是RTC、低速时钟的标准频率);
  • 频率精度:常温频差±50ppm(换算为±1.6384Hz,满足大多数嵌入式系统的时间校准要求);
  • 电压范围:1.8V~5V宽电压兼容,适配单片机、MCU、蓝牙模块等不同供电需求;
  • 工作电流:5mA(典型值,平衡驱动能力与功耗);
  • 温度适应性:-40℃~+85℃工业级工作温度,频率稳定度±50ppm(极端温度下仍保持可靠输出);
  • 封装形式:SMD3225-4P(3.2×2.5mm贴片4脚,体积小巧,兼容自动化贴装)。

二、关键性能特点

1. 精准稳定的时钟输出

32.768kHz是全球公认的RTC基准频率,该产品常温频差±50ppm,结合±50ppm的温度稳定度,可确保在-40℃~+85℃范围内,频率漂移控制在可接受区间,避免时间校准频繁或误差累积。

2. 宽电压适配性

1.8V~5V的电压范围覆盖了从低功耗MCU(如STM32L系列)到传统5V单片机的供电需求,无需额外电平转换电路,简化系统设计,降低BOM成本。

3. 工业级环境可靠性

-40℃~+85℃的工作温度范围,支持户外、车载、工业控制等极端场景;同时通过雅晶鑫的高低温存储、温度循环等可靠性测试,确保长期使用中参数一致性。

4. 便捷封装与应用

SMD3225-4P贴片封装体积仅3.2×2.5mm,符合现代电子设备小型化趋势(如智能手表、穿戴设备);CMOS输出模式与主流数字电路电平匹配,无需缓冲电路,直接对接MCU时钟输入引脚。

三、典型应用场景

1. 实时时钟(RTC)模块

智能手表、智能家居控制器、工业传感器节点等设备的时间基准,可实现断电后时间保持(配合备用电池),避免重启后时间重置。

2. 低功耗物联网(IoT)终端

蓝牙低功耗(BLE)模块、温湿度传感器、智能门锁等IoT设备的低速时钟源,平衡功耗与频率精度,延长电池续航。

3. 汽车电子与医疗设备

车载信息娱乐系统、便携式监护仪等设备的辅助时钟,适应汽车舱内高温/低温环境,满足医疗设备对时间同步的要求。

4. 消费电子与工业控制

机顶盒、路由器的时间同步;PLC、远程IO模块的时钟基准,适配工业级温度与振动环境。

四、设计与使用注意事项

  1. 布局优化:晶振应靠近MCU时钟输入引脚,减少走线长度,避免靠近高速信号线(如SPI、USB),防止电磁干扰;
  2. 电源滤波:在晶振电源引脚(VCC)与地之间并联0.1μF陶瓷电容,过滤电源噪声,提升频率稳定性;
  3. 负载电容匹配:根据晶振负载电容要求(通常12pF或6pF),在输出引脚(OUT)与地之间并联对应电容,确保频率精准;
  4. 焊接工艺:采用回流焊工艺,温度曲线需符合SMD3225封装的焊接要求(避免峰值温度过高导致晶振参数漂移)。

五、品牌与品质保障

雅晶鑫(YJX)作为国内专业晶振制造商,具备成熟的晶体生产工艺与测试体系:

  • 产品经过高低温存储(+85℃×1000h、-40℃×1000h)、温度循环(500次)、振动测试(IEC 60068-2-6)等可靠性验证;
  • 批量供货时参数一致性好,降低客户样品与量产的兼容性风险。

TFOM32768K4RHKCNT2T凭借精准频率、宽电压、工业级可靠性等特点,成为各类电子设备时钟基准的高性价比选择,适配从消费电子到工业控制的多元应用场景。

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
