SCTF SXTF321532768G10F 32.768kHz贴片晶振产品概述

一、产品定位与核心特点

SXTF321532768G10F是星通时频(SCTF)针对低功耗高精度时间基准需求推出的32.768kHz贴片晶振,核心定位为消费电子、物联网、工业控制等场景的通用时钟源。其核心特点聚焦于:

  1. 标准RTC频率:32.768kHz是MCU/SoC实时时钟(RTC)的黄金频率,适配90%以上主流芯片的RTC模块;
  2. 小型化封装:SMD3215贴片尺寸(3.2×1.5mm),满足智能手机、智能手表等轻薄设备的高密度PCB设计;
  3. 宽温可靠性:-40℃~+85℃工业级温度范围,覆盖户外、车间等 harsh环境;
  4. 低功耗适配:70kΩ等效串联电阻(ESR),降低电池供电设备的静态功耗,延长续航。

二、关键参数解析

该晶振的核心参数直接决定应用适配性,具体解析如下:

  • 频率与频差:标称频率32.768kHz,常温(25℃)频差±10ppm——即频率偏差控制在百万分之十以内,换算为时间误差:24小时内偏差约0.86秒,满足大多数消费电子、工业设备的RTC精度要求;
  • 负载电容:9pF——需匹配电路中9pF的负载电容,确保晶振工作在谐振状态,避免频率偏移;
  • 频率稳定度:±30ppm——指温度、电压变化时的最大频偏,覆盖宽温范围,极端环境下仍能维持时间稳定性;
  • ESR:70kΩ——等效串联电阻,直接影响晶振起振稳定性与功耗,70kΩ属于低功耗级,适合电池供电设备;
  • 工作温度:-40℃~+85℃——工业级标准,可应用于户外传感器、车载辅助时钟等场景。

三、封装与可靠性设计

SXTF321532768G10F采用SMD3215贴片封装,具备以下可靠性优势:

  • 抗振动性能:无引脚外露设计,焊接后与PCB贴合紧密,能承受10g(10-2000Hz)振动测试,适配移动设备(如手持终端、车载电子);
  • 宽温稳定性:经过-40℃~+85℃高低温循环测试,无频率漂移、起振异常,满足工业级环境要求;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅焊接兼容,可进入全球主流市场。

四、典型应用场景

结合参数与封装特性,该晶振广泛适配以下场景:

  1. 消费电子:智能手机、平板、智能手表的RTC模块(关机后维持时间);
  2. 物联网设备:传感器节点、智能门锁、智能家居控制器(低功耗延长电池寿命);
  3. 工业控制:PLC、工业传感器、数据采集器(宽温适应车间/户外环境);
  4. 通信设备:路由器、机顶盒、基站辅助时钟(稳定频率保障数据同步);
  5. 车载电子:车载中控、行车记录仪的辅助时钟(抗振动、宽温适配车载环境)。

五、品牌与品质保障

SCTF(星通时频)是国内专业频率控制厂商,具备10+年晶振研发生产经验,SXTF321532768G10F的品质保障体现在:

  • 一致性管控:批量生产中频差、ESR一致性达±5%以内,适合大规模量产;
  • 可靠性测试:通过振动、冲击、高低温循环等10余项测试,MTBF(平均无故障时间)超100万小时;
  • 技术支持:提供电路匹配方案、焊接工艺指导,帮助客户快速集成应用。

该产品凭借“高精度、小体积、宽温可靠”的特性,成为中小批量电子设备的高性价比时钟源选择。

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
