TCXM32768K2NGDCZT2T 贴片晶振产品概述

一、产品核心定位

TCXM32768K2NGDCZT2T是雅晶鑫(YJX)推出的SMD3215-2P封装低频高精度贴片晶振,以32.768kHz为基准频率,专为需要稳定计时基准的电子设备设计。其核心优势在于兼顾小型化、宽温适应性与高精度,可满足工业级、消费级等多场景的量产需求,是RTC(实时时钟)、计时电路的主流选型之一。

二、基础电气参数详解

该晶振的电气性能针对计时类应用做了针对性优化,关键参数的实际价值如下:

  • 频率特性:标称频率32.768kHz(RTC领域标准计时频率),常温(25℃)频差±20ppm,可保证日常计时精度(每日误差约0.5秒内);全温范围(-40℃~+85℃)频率稳定度±30ppm,覆盖工业环境温变的精度需求,避免极端温度下计时漂移。
  • 负载电容:12.5pF,适配主流MCU(如STM32、ESP32)、SoC的RTC接口内置负载电容,无需额外匹配电容,简化电路设计与BOM成本。
  • 等效串联电阻(ESR):80kΩ,处于贴片32.768kHz晶振的合理区间——既保障电路易起振,又能降低振荡电路功耗(低ESR有助于减少电流消耗,适合低功耗设备)。

三、封装与物理特性

采用SMD3215-2P标准贴片封装,尺寸为3.2mm×1.5mm×0.8mm(长×宽×高),2引脚设计,符合SMT自动化贴装工艺,可直接集成到高密度PCB中。封装材料为无铅环保(RoHS compliant),满足全球电子设备的环保要求,同时具备2kV ESD抗静电能力,避免生产过程中静电损伤。

四、环境适应性表现

该晶振经过严格可靠性测试,可适应复杂应用场景:

  • 工作温度:-40℃~+85℃,覆盖工业级环境(如户外传感器、车载电子)的温变范围,低温下无频率漂移加剧问题,高温下保持稳定输出;
  • 机械性能:抗振动(102000Hz,加速度1g)、抗冲击(1000g/0.1ms),可承受设备运输、安装中的机械应力;存储温度-55℃+125℃,长期存储无性能衰减;
  • 湿度耐受性:可在5%~95%相对湿度(无凝露)环境下稳定工作,适合潮湿地区或户外设备应用。

五、品牌与品质保障

雅晶鑫(YJX)作为国内专业晶振制造商,该产品通过全流程品质管控:

  • 24小时常温老化+高低温循环老化,筛选性能稳定的产品;
  • 符合IEC 60747、GB/T 14862等行业标准;
  • 批量供应一致性好,可满足10k~100k级别的量产需求,提供稳定供货周期。

六、典型应用场景

TCXM32768K2NGDCZT2T的核心应用集中在需要稳定计时基准的领域:

  1. RTC模块:智能手环、智能手表、物联网传感器节点(如温湿度传感器)的时间同步;
  2. 工业控制:PLC、工业相机、工业传感器的计时与数据时间戳;
  3. 消费电子:手机、平板电脑、智能音箱的辅助计时(补充主时钟精度);
  4. 车载电子:车载导航、行车记录仪的时间显示与数据同步;
  5. 医疗设备:小型医疗仪器(如血糖仪、血压计)的时间戳记录,确保数据可追溯。

该晶振以高性价比、宽温稳定的特性,成为多领域电子设备计时基准的可靠选型。

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
