TXM3.6864M0002491LFBEO00T 无源贴片晶振产品概述

TXM3.6864M0002491LFBEO00T是雅晶鑫(YJX)推出的一款工业级无源贴片晶振,采用HC-49S-SMD封装,专为普通电子设备的时钟基准设计,兼具稳定性与性价比,适用于多种中小批量应用场景。

一、产品基本信息定位

该晶振属于无源石英晶体谐振器,无需外部驱动电路即可与振荡电路配合产生稳定时钟信号。型号中“3.6864M”明确核心频率,“LFBEO00T”为雅晶鑫内部规格编码,整体定位为通用型工业级无源晶振,覆盖-20℃~+70℃工作温度范围,满足大多数室内及轻度户外电子设备的时钟需求。

二、核心性能参数详解

1. 频率与精度指标

  • 标称频率:3.6864MHz,是串口通信(UART)常用基准频率之一(可分频得到11.0592MHz等兼容波特率的频率),兼容性强;
  • 常温频差:±30ppm,即常温(25℃左右)下频率偏差不超过±110.592Hz,满足一般数字电路时钟精度要求,无需额外温补;
  • 频率稳定度:±30ppm,指工作温度范围内频率变化不超过±30ppm,确保设备在温度波动下时钟信号稳定,避免通信误码或功能异常。

2. 电气与机械参数

  • 负载电容:20pF,需与振荡电路匹配电容(通常10~22pF)配合,设计时需注意PCB寄生电容影响;
  • 等效串联电阻(ESR):100Ω,数值适中,既保证易起振,又避免因ESR过高导致振荡幅度不足或功耗过大;
  • 封装:HC-49S-SMD,贴片式封装,尺寸紧凑(兼容传统HC-49S插件的SMT生产),节省PCB空间,支持自动化贴装。

三、典型应用场景

该晶振因频率兼容性好、成本适中,广泛应用于以下场景:

  1. 串口通信模块:单片机(STC、ATmega等)UART时钟源,配合11.0592MHz分频实现精准波特率(9600bps、19200bps等);
  2. 小型电子仪器:简易示波器、信号发生器的基准时钟,满足低速信号处理需求;
  3. 智能家居与消费电子:智能遥控器、小型家电(加湿器、智能插座)控制板时钟,适应室内温度变化;
  4. 工业控制单元:小型PLC、传感器节点的辅助时钟,覆盖-20℃~+70℃工作环境。

四、可靠性与选型注意事项

  1. 可靠性特点:无源晶振无内置驱动电路,寿命长(≥10万小时),抗干扰能力较强,电路匹配正确则振荡稳定性高;
  2. 选型要点:
    • 确认振荡电路负载电容匹配(20pF),避免起振困难或频率偏移;
    • 若温度范围超-20℃~+70℃,需考虑温补/恒温晶振;
    • 贴片封装需按HC-49S-SMD标准设计焊盘,避免焊接缺陷。

五、品牌与质量保障

雅晶鑫(YJX)是国内专注石英晶体谐振器的制造商,产品通过高低温循环、振动测试、老化测试等常规可靠性验证,符合电子元器件行业基本标准,适合中小批量设备选型,性价比优势明显。

该晶振以稳定性能、紧凑封装和合理成本,成为众多电子设备时钟基准的优选方案之一。

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
