GM32768KGBCZ2X 产品概述

一、产品简介

GM32768KGBCZ2X 是雅晶鑫(YJX)推出的一款国产贴片晶振,工作频率为 32.768 kHz,封装规格为 SMD3215。该器件专为低频实时时钟(RTC)与低功耗定时应用设计,具有低功耗、高稳定性和良好的温度特性,适合批量生产和消费类、工业类终端使用。

二、主要规格

  • 型号:GM32768KGBCZ2X
  • 品牌:YJX(雅晶鑫)
  • 频率:32.768 kHz(KHz 级贴片晶振)
  • 常温频差:±10 ppm(室温参考)
  • 频率稳定度(环境温度范围内):±30 ppm
  • 负载电容:12.5 pF
  • 等效串联电阻(ESR):60 kΩ
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SMD3215(3215 尺寸贴片)

三、主要特性与优势

  • 高频率精度高:常温下±10 ppm 的初始频差,满足对时间基准精度要求较高的应用。
  • 温度稳定性好:在-40~+85 ℃ 范围内频率稳定度可达±30 ppm,适配大多数工业和消费级环境。
  • 低等效串联电阻:60 kΩ 的 ESR 有利于低驱动电流和低功耗运行,适合电池供电设备。
  • 小型贴片封装:SMD3215 封装便于表面贴装生产,良好的一致性和可焊性,适合自动化贴装线。

四、典型应用场景

  • 实时时钟(RTC)模块与日历时钟
  • 便携式手表、计时器、电子辞典等穿戴与消费类产品
  • 低功耗 MCU 的唤醒时钟与睡眠定时器
  • 物联网终端、远程数据采集、传感器节点
  • 医疗监护与测量仪器中的时间基准

五、使用与选型建议

  • 负载电容匹配:晶振标称负载电容为 12.5 pF。若使用外接对称电容 C1=C2,可按 C ≈ 2×(C_L − C_stray) 估算(C_stray 包括引脚与 PCB 寄生电容,通常为 25 pF),常见取值在 1522 pF 范围,最终以电路板实际测量调整为准。
  • 布局与走线:晶振应尽量靠近 MCU 的振荡引脚放置,走线最短且对称,避免穿过高频或大电流回路,晶振两端走线应远离数字信号干扰源。
  • 接地与去耦:为降低噪声干扰,晶振附近应有稳定的地平面与合适的旁路元件;若 MCU 支持内部匹配,按 MCU 厂商建议布板与配置。
  • 驱动能力:注意 MCU 振荡电路的驱动能力与该晶振的 ESR 匹配,确保振荡器能稳定启动。

六、可靠性与品质控制

GM32768KGBCZ2X 在-40~+85 ℃ 工作温度范围内提供稳定性能,适合工业级到消费级应用。雅晶鑫在生产过程中对频率精度、ESR 与封装一致性进行控制,满足表贴生产需求。具体可靠性测试与放行标准建议参考厂商完整数据手册与检验报告。

七、总结

GM32768KGBCZ2X 是一款面向低频定时与实时时钟应用的高精度贴片晶振,凭借 32.768 kHz 标准频率、±10 ppm 常温精度、12.5 pF 负载以及低 ESR 和宽温范围,适用于对功耗、体积及时间精度有要求的各类电子设备。选型时应关注负载电容匹配与 PCB 布局细节,以保证振荡稳定与长期可靠性。

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
