TXM6.7458M0002491LFBEO00T 无源贴片晶振产品概述
一、产品基本属性
TXM6.7458M0002491LFBEO00T是雅晶鑫（YJX）推出的无源贴片晶振，采用HC-49S-SMD封装（贴片式结构，兼容传统HC-49S插件封装的贴装工艺需求）。作为无源晶体谐振器，它无需外部电源驱动，依赖振荡电路提供能量维持谐振，是电子电路中稳定时钟信号的核心元件之一。
二、核心性能参数
该晶振的关键性能参数贴合常规消费电子与工业设备的时钟精度需求，具体如下：
- 标称频率：6.7458MHz，属于音频、通信中频附近的常用频率段，适配多种信号同步场景；
- 常温频差：±30ppm（百万分比），换算后常温频率波动不超过±202Hz，满足大多数设备的时序精度要求；
- 负载电容：推荐匹配20pF，需在振荡电路中按此参数配置电容，保证谐振频率准确；
- 全温频率稳定度：±30ppm，意味着在-20℃至+70℃区间内，频率偏差不超过标称值的±30ppm；
- 等效串联电阻（ESR）：最大80Ω，属于无源晶振的常规水平，需匹配电路驱动能力避免振荡不稳定；
- 工作温度范围：-20℃至+70℃，覆盖室内常温、部分户外温和环境及常规工业设备温区。
三、典型应用场景
因频率稳定、封装适配性强，该晶振可广泛用于以下场景：
- 通信设备：小型无线路由器、蓝牙/WiFi模块的时钟基准，为信号收发提供稳定频率参考；
- 消费电子：智能穿戴（如智能手表）计时电路、便携式音频（如蓝牙耳机）信号同步；
- 工业控制：小型PLC、传感器模块的时钟源，保障数据采集与处理的时序稳定；
- 车载配件：低功耗车载设备（如蓝牙适配器、行车记录仪辅助电路）的时钟信号发生，适配车载常规温区。
四、选型与使用注意事项
为确保性能稳定，需注意以下要点：
- 负载电容匹配：严格按20pF配置振荡电路，电容偏差过大会导致频率偏离标称值；
- 温区适配：仅适用于-20℃至+70℃，避免极端温区（如低温-20℃以下、高温70℃以上）使用；
- 驱动能力匹配：80Ω ESR需匹配电路驱动能力，驱动不足可能导致振荡幅度不够或无法起振；
- 焊接规范：HC-49S-SMD为贴片封装，需确认PCB焊盘尺寸一致，焊接时控制温度避免不良。
该晶振凭借实用的性能参数、便捷的贴片封装，成为多类电子设备时钟电路的可靠选型。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
