TAXM32768KBGBAZN2T 产品概述

一、产品简介

TAXM32768KBGBAZN2T 是雅晶鑫(YJX)推出的一款贴片圆柱形晶体谐振器,标准频率为 32.768kHz,专为低功耗实时时钟(RTC)与计时应用设计。封装为 SMD D2×L6mm,蛙腿(gull‑leg)引脚形式,适配自动化贴装与焊接工艺。常温频差优异,为 ±10ppm,适合对时间精度有较高要求的系统。

二、主要参数(关键规格)

  • 频率:32.768 kHz
  • 常温频差:±10 ppm(室温)
  • 频率稳定度:±30 ppm(全温度范围)
  • 负载电容:12.5 pF
  • 等效串联电阻(ESR):50 kΩ
  • 工作温度范围:-20 ℃ ~ +70 ℃
  • 封装:SMD,圆柱 D2×L6mm,蛙腿引脚
  • 品牌:YJX(雅晶鑫)

三、产品特点

  • 高精度:常温 ±10ppm,适合精准计时与长期走时稳定性要求的设备。
  • 低频低功耗:32.768kHz 为 RTC 与计时器常用频点,配合 MCU 内部低功耗振荡输入可实现极低静态功耗。
  • 易于贴装:SMD 封装与蛙腿焊脚兼容现有 SMT 生产线,减少装配成本。
  • 宽温度适用:-20~+70℃ 满足消费类与多数工业类应用的工作环境需求。
  • 良好 ESR 性能:ESR 50kΩ,适配大多数微控制器/振荡器电路(请参考控制器数据手册中对 ESR 的兼容性要求)。

四、典型应用场景

  • 实时时钟(RTC)模块与主板时钟源
  • 可穿戴设备、智能手表与健康监测设备
  • 智能家居、计时器、闹钟与电子秤
  • 物联网节点、远程抄表与低功耗传感器端节点
  • 医疗设备与数据记录模块的时间基准

五、选型与电路建议

  • 负载电容匹配:器件标称 CL = 12.5 pF。若使用对称负载 C1=C2,则推荐两侧并联电容值约为 2×(CL - Cstray)。典型 PCB 寄生电容(Cstray)为 23 pF,因此可选 C1=C2 ≈ 1822 pF(按实际板级寄生校验并微调)。
  • 驱动与互联:由于 ESR 较高,建议采用具有较大增益或专用晶体振荡器输入的 MCU 引脚;参考 MCU 厂商提供的石英/晶体匹配表与启动条件。
  • 布局注意:晶体与其负载电容应靠近 MCU 振荡器引脚,避免通过数字信号线或噪声源,接地需良好且短回路。
  • 焊接工艺:兼容标准 SMT 工艺,焊接与清洗请遵循厂方推荐的温度曲线与工艺规范,避免超出器件允许的热应力。

六、可靠性与注意事项

  • 储存与装配时避免强烈机械冲击与弯折引脚;长时间存放建议防潮包装并避免高温高湿环境。
  • 使用前若板级经过大温差回流或湿度暴露,按厂方建议进行预烘烤以消除潜在吸湿风险(请向供应商确认是否必需)。
  • 若对更宽温区、超低频偏或更低 ESR 有需求,可咨询雅晶鑫提供替代型号或定制服务。

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
