SX3B40.000F1010F30 无源贴片晶振产品概述

一、产品基本身份

SX3B40.000F1010F30是星通时频(SCTF) 推出的一款无源石英贴片晶振,采用行业标准SMD3225-4P封装,核心频率为40MHz,定位于中高精度、宽温适应的通用型时钟基准器件,可满足消费电子、工业控制等多领域的时钟需求。

二、关键性能参数解析

该晶振的参数直接决定了其应用适配性,具体拆解如下:

(1)频率与精度指标

  • 标称频率:40MHz,属于中高频段,是通信、工业设备中常见的时钟基准频率,适配多数射频芯片、微控制器的时钟输入要求;
  • 常温频差:±10ppm,即25℃常温下频率偏差不超过40MHz×10×10⁻⁶=400Hz,满足普通消费电子到中等精度工业设备的精度需求;
  • 频率稳定度:±30ppm,包含温度变化(-40℃~+85℃)、电源波动等环境因素带来的总偏差,整体稳定性符合工业级设备的可靠性要求。

(2)电气与环境参数

  • 负载电容:10pF,是晶振与振荡电路匹配的核心参数——电路中并联/串联电容的总容量需与10pF一致,否则会导致频率偏移超出规格;
  • 等效串联电阻(ESR):30Ω,串联等效电阻越小,晶振起振越容易、功耗越低,30Ω属于低ESR水平,适配低功耗电路设计;
  • 工作温度范围:-40℃~+85℃,覆盖工业环境的高低温波动(如车间、户外网关),也可适应车载周边设备的温度变化。

三、封装与物理特性

  • 封装类型:SMD3225-4P(4引脚贴片封装),尺寸为3.2mm×2.5mm×0.8mm(典型厚度),体积小巧,适合小型化设备的高密度贴装;
  • 引脚配置:4引脚为标准石英晶振设计,无极性要求,焊接时无需区分方向,降低生产难度;
  • 贴装兼容性:支持回流焊、波峰焊等自动化SMT工艺,符合工业生产线的标准化要求,可直接集成于PCB板。

四、典型应用场景

结合参数特性,该晶振主要适配以下场景:

  1. 工业控制设备:PLC、传感器模块、工业物联网网关等,宽温范围满足车间、户外工业环境的温度波动;
  2. 消费电子终端:智能穿戴(手表、手环)、机顶盒、路由器等,小型化封装适配设备轻薄化需求;
  3. 通信辅助模块:蓝牙、WiFi、LoRa等低功耗通信模块的时钟基准,40MHz频率与多数射频芯片的时钟要求匹配;
  4. 车载周边设备:车载充电器、行车记录仪等非核心车载部件,宽温范围适应车内-40℃~+85℃的温度变化。

五、应用注意事项

为保证晶振稳定工作,需注意以下要点:

  1. 负载电容匹配:振荡电路中需配置总负载电容为10pF(通常采用两个22pF电容并联,或根据电路拓扑调整),避免频率偏差;
  2. ESR适配:振荡电路的驱动电流需≥1mA(适配30Ω ESR),防止起振困难或停振;
  3. 环境防护:避免工作温度超出-40℃~+85℃,远离强电磁干扰源(如高频变压器),防止频率偏移;
  4. 焊接工艺:回流焊峰值温度≤260℃,焊接时间≤10秒,避免高温损坏内部石英晶体。

六、产品核心优势

SX3B40.000F1010F30的竞争优势可概括为:

  • 精度与稳定:常温±10ppm频差+宽温±30ppm稳定度,覆盖多场景精度需求;
  • 宽温适应:-40℃~+85℃工作范围,适配工业、车载等极端环境;
  • 低耗小型化:30Ω低ESR+SMD3225封装,兼顾低功耗与设备轻薄化;
  • 高可靠性:星通时频的工业级设计,符合RoHS无铅环保要求,适合长期稳定工作。

该产品凭借均衡的性能与成本控制,成为中低端电子设备时钟基准的高性价比选择。

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
