TAXM25M4RFBCCT2T 贴片晶振产品概述

一、产品核心身份与定位

TAXM25M4RFBCCT2T是雅晶鑫(YJX)推出的工业级通用型贴片石英晶振,主打“小型化、宽温稳定、高性价比”三大核心优势,是替代传统插件晶振的主流选型之一。该型号针对中精度时钟需求场景优化,兼顾贴装效率与环境适应性,适用于多数消费电子、工业控制及通信设备的时钟基准设计。

二、关键性能参数详解

1. 频率与精度指标

  • 标称频率:25MHz(主流通用频率,适配多数微控制器、通信接口);
  • 常温频差:±10ppm(换算为频率偏差±250Hz,满足中精度时钟需求,如蓝牙/WiFi同步);
  • 全温频率稳定度:±50ppm(覆盖-40℃~+85℃工作温度,极端环境下频率偏移可控,适配工业/车载场景)。

2. 负载与阻抗特性

  • 负载电容:12pF(需与振荡电路等效负载匹配,避免频率偏移;实际设计需计入PCB/引脚寄生电容);
  • 等效串联电阻(ESR):80Ω(常规石英晶振阻抗范围,与多数微控制器内置振荡器兼容,保证振荡裕量)。

3. 电气兼容性

适配3.3V/5V常规系统电压,输出波形为正弦波(可通过振荡电路转换为方波),相位噪声满足通用电子设备要求。

三、封装与贴装适配性

采用SMD3225-4P封装:

  • 尺寸:3.2mm×2.5mm×0.8mm(小型化设计,节省PCB空间,适配智能穿戴、便携设备);
  • 引脚:4引脚贴片式,符合IPC标准焊盘要求,支持自动化SMT贴装与回流焊工艺(贴装效率≥99%,适合批量生产);
  • 焊盘要求:需遵循雅晶鑫推荐的焊盘尺寸(典型:焊盘长1.6mm,宽0.8mm,间距2.0mm),避免虚焊或短路。

四、环境与可靠性表现

1. 宽温适应性

  • 工作温度:-40℃~+85℃(覆盖工业级与商业级场景,可用于户外设备、车载周边);
  • 存储温度:-55℃~+125℃(满足运输与长期存储的温度要求)。

2. 可靠性指标

  • 通过振动(10~2000Hz,1.5g)、冲击(1000g/0.5ms)测试,抗机械应力能力强;
  • 符合RoHS无铅无卤标准,适配绿色电子设计;
  • 额定使用寿命:≥10年(在额定工作条件下,频率老化率≤±5ppm/年)。

五、典型应用场景

  1. 通信设备:路由器、蓝牙/WiFi模块、4G/5G小基站的时钟同步;
  2. 消费电子:机顶盒、智能电视、智能音箱的微控制器时钟源;
  3. 工业控制:PLC、传感器节点、电机控制器的基准时钟(适配工业现场振动/宽温);
  4. 智能穿戴:智能手表、手环的低功耗时钟(兼顾小型化与稳定性);
  5. 车载电子:车载导航、行车记录仪的辅助时钟(满足-40℃~+85℃车载环境)。

六、选型与使用注意事项

  1. 负载电容匹配:电路设计需计算“振荡电路等效负载电容+PCB寄生电容+引脚寄生电容”,确保总负载为12pF(偏差≤±1pF),避免频率偏移;
  2. 振荡裕量验证:需确认振荡电路驱动能力(如微控制器内置振荡器的驱动电流),建议振荡裕量(驱动能力/ESR)≥3,保证稳定振荡;
  3. 贴装工艺:遵循回流焊温度曲线(预热150180℃/60120s,回流峰值230245℃/1020s),避免高温损坏晶振;
  4. 静电防护:晶振为静电敏感元件(ESD等级≥2kV),贴装/焊接需佩戴防静电手环,工作台接地;
  5. 温度范围确认:若应用场景温度超出-40℃~+85℃(如低温环境),需选择宽温型晶振,不可使用本型号。

该型号凭借稳定的性能、小型化封装及宽温适应性,已成为雅晶鑫旗下的成熟通用晶振产品,广泛应用于中低端电子设备的时钟设计中。

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
