SX3M25.000M20F30TNN有源晶振产品概述

一、产品定位与核心特性

SX3M25.000M20F30TNN是星通时频(SCTF) 推出的一款工业级SMD封装有源晶振,针对中低端到中端电子系统对频率稳定性、宽电压适应性、小尺寸的需求设计。核心特性聚焦于:

  • 工业级温度范围(-40℃~+85℃);
  • 1.62V~3.63V宽电压兼容主流MCU供电;
  • 10mA低功耗适配便携/电池设备;
  • 无需外部负载电容,简化电路设计。

该产品可覆盖工业控制、消费电子、物联网等多场景,是平衡成本与性能的实用选型。

二、关键参数深度解析

1. 频率与精度指标

  • 标称频率:25MHz(固定频率,出厂校准,无需用户二次调试);
  • 常温频差:±20ppm(25℃环境下,实际频率偏差≤±500Hz,满足常规通信、控制类设备的时序需求);
  • 全温频率稳定度:±30ppm(覆盖-40℃~+85℃全工作温度,偏差≤±750Hz,避免高低温下频率漂移导致系统误判);
  • 型号命名逻辑:“20F30”直接对应“常温频差20ppm+全温稳定度30ppm”,便于选型识别。

2. 供电与输出特性

  • 工作电压:1.62V~3.63V宽范围(适配1.8V、3.3V等主流MCU/SoC供电,无需额外电平转换);
  • 典型工作电流:10mA(有源晶振中属于中等偏低功耗,适合电池供电的便携设备或功耗敏感型系统);
  • 输出模式:CMOS(逻辑电平兼容TTL/CMOS,输出高电平≥VCC-0.5V,低电平≤0.5V,驱动能力满足大多数数字电路输入需求)。

3. 环境与可靠性

  • 工作温度:-40℃~+85℃(工业级标准,可应对户外设备、车间控制等恶劣环境);
  • 存储温度:默认-55℃~+125℃(星通时频该系列标准,保障运输/存储稳定性);
  • 长期老化率:典型≤±1ppm/年(长期运行中频率漂移极小,避免系统性能衰减)。

三、封装与引脚配置

SX3M25采用SMD3225-4P封装(3.2×2.5mm超小尺寸,适合高密度PCB布局),4引脚功能明确:

引脚编号 功能 注意事项 1 VCC 电源输入(1.62V~3.63V) 2 GND 接地(需可靠连接,避免虚焊) 3 OUT CMOS频率输出(25MHz) 4 NC 空脚(无需焊接,避免短路)

关键提示:有源晶振无需外部负载电容,直接焊接即可输出稳定频率,简化电路设计。

四、典型应用场景

1. 工业控制设备

  • 应用:PLC(可编程逻辑控制器)、传感器节点、电机驱动模块;
  • 适配点:宽温范围(-40~85℃)应对车间/户外工业环境,全温稳定度±30ppm保障控制时序精准。

2. 消费电子与便携设备

  • 应用:智能手表、蓝牙音箱、智能家居终端;
  • 适配点:1.62V~3.63V宽电压适配1.8V/3.3V供电,10mA低电流延长电池续航,小尺寸适合紧凑PCB。

3. 物联网(IoT)模块

  • 应用:Wi-Fi模块、LoRa网关、环境传感器节点;
  • 适配点:稳定的25MHz频率满足无线通信载波同步需求,工业级温度适合户外部署。

4. 入门级汽车电子

  • 应用:车载显示屏、倒车雷达控制单元;
  • 适配点:-40~85℃温度范围应对车内高低温,宽电压适配车载12V转3.3V供电系统(需降压)。

五、品质与使用注意事项

1. 品牌与认证

  • 星通时频(SCTF)是国内专业时频器件厂商,产品符合RoHS、REACH环保标准,通过ISO9001质量管理体系认证。

2. 焊接与布局规范

  • 焊接:采用回流焊工艺,峰值温度≤260℃(持续时间≤10s),避免手工焊接过热损坏;
  • 供电:严禁超过3.63V最高电压,禁止1脚(VCC)与2脚(GND)反向接电;
  • 布局:OUT引脚尽量靠近MCU时钟输入引脚,减少走线长度,避免电磁干扰。

六、总结

SX3M25.000M20F30TNN是一款高性价比工业级有源晶振,以小尺寸、宽电压、宽温稳定、低功耗为核心优势,覆盖多场景应用需求。无需外部负载电容的设计简化了电路,适合对成本敏感且需要稳定频率的中低端电子系统选型,是替代同类进口器件的优质国产方案。

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.
