TAXM10M2GLFBET2T 无源贴片晶振产品概述

一、产品基本定位

TAXM10M2GLFBET2T是雅晶鑫(YJX)推出的通用型无源贴片晶振,属于HC-49S封装系列的表面贴装版本。作为无源晶振,它无内置振荡电路,需外接MCU、ASIC等芯片的振荡引脚配合电容实现稳定振荡,核心定位是中低端电子设备的基础时序基准——兼顾成本控制与生产适配性,适合批量应用于消费电子、小型工业控制等场景,无需高精度但需稳定时钟的设备。

二、核心参数详解

该晶振的参数围绕“实用稳定”设计,关键指标及实际意义如下:

  1. 频率与频差:基准频率10MHz(电子设备最常用的时钟基准之一);常温(25℃)频差±30ppm,即常温下频率偏差不超过±300Hz(10MHz×30×10⁻⁶),满足多数非高精度时序需求(如控制板的指令同步、传感器的采样时钟)。
  2. 负载电容与ESR:负载电容20pF(无源晶振振荡的核心匹配参数),实际电路需在晶振两端各串联/并联10pF左右电容(需结合PCB寄生电容微调),确保总负载电容达标;等效串联电阻(ESR)80Ω,属于无源晶振常规水平,可保障振荡启动速度(无延迟)与稳定性(无频繁停振)。
  3. 温度特性:工作温度-20℃+70℃,频率稳定度±30ppm(温度变化范围内频率偏差≤±300Hz),能应对室内环境、常规工业现场的温度波动(如车间25℃50℃、家庭10℃~35℃)。

三、封装与结构特点

采用HC-49S-SMD贴片封装,是无源晶振的经典小型化封装,优势明显:

  1. 体积紧凑:典型尺寸3.8mm×1.5mm×1.2mm,适配小型化设备(如智能手环、微型传感器)的PCB布局,不占用过多空间;
  2. 贴装适配:2脚贴片设计,支持SMT自动化贴装,生产效率比插件HC-49S提升50%以上,减少人工操作误差;
  3. 防护可靠:石英晶体片封装于金属/塑料外壳内,隔离灰尘、湿度对晶体的影响,使用寿命可达5年以上(常规使用环境下)。

四、典型应用场景

基于参数与封装特点,TAXM10M2GLFBET2T适配以下场景:

  1. 消费电子:小型家电(微波炉控制板、加湿器显示屏)、低端智能穿戴(基础款手环的时钟基准)、蓝牙音频模块(旧款蓝牙耳机的低速率时钟);
  2. 小型工业控制:PLC扩展模块、温度传感器节点、小型电机驱动板的时序控制;
  3. 通信辅助设备:433MHz无线遥控器、RS485模块的时钟源;
    注意:因工作温度未覆盖汽车级(-40℃~+85℃),不建议用于车载核心系统,但可用于车载辅助设备(如车载充电器的状态显示)。

五、性能优势总结

  1. 成本可控:无源晶振无内置振荡电路,相比有源晶振成本降低30%以上,适合批量采购;
  2. 通用适配:10MHz频率兼容绝大多数MCU(STM32、51系列等)的OSC引脚,无需额外频率转换;
  3. 生产友好:贴片封装支持自动化贴装,提升产品一致性,降低生产损耗;
  4. 稳定可靠:±30ppm的频差与温稳,满足90%以上常规电子设备的时序需求,无高频漂移问题。

该晶振是中低端电子设备的“性价比之选”,在保证基础时钟稳定的前提下,兼顾了成本与生产效率,适合对精度要求不苛刻但需批量应用的场景。

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
