TAXM8M4RFDCET2T 无源贴片晶振产品概述

TAXM8M4RFDCET2T是雅晶鑫(YJX)推出的一款无源石英贴片晶振,采用SMD3225-4P封装,以8MHz核心频率为核心,适配工业级温度范围,广泛应用于各类需要稳定时钟基准的电子设备中,是小型化、低成本设计的优选方案。

一、产品基本属性

该晶振属于无源晶振(需外部振荡电路驱动,无内置放大电路),核心属性如下:

  • 品牌:雅晶鑫(YJX),国内专业晶振制造商,产品覆盖工业、消费电子等领域,可靠性经批量验证;
  • 封装:SMD3225-4P,尺寸为3.2mm×2.5mm(行业标准贴片尺寸),厚度约1.0mm,适配高密度PCB贴装;
  • 引脚:4引脚配置,引脚间距符合SMT自动化贴片机要求,无需额外焊接辅助即可集成到电路板。

二、核心电气参数解析

TAXM8M4RFDCET2T的电气性能平衡了精度、稳定性与成本,关键参数如下:

  1. 核心频率:8MHz,属于中低频石英晶振的常用规格,适配多数MCU/MPU的系统时钟倍频需求(如STM32F1系列可通过8MHz倍频至72MHz);
  2. 常温频差:±20ppm,换算为频率偏移量为**±160Hz**(8MHz×20×10⁻⁶),可满足工业控制、消费电子对时钟精度的基本要求,无需温补即可稳定计时;
  3. 负载电容:12pF,无源晶振需外接匹配的负载电容(通常为两个12pF电容并联于晶振两端与地之间),若负载电容偏差过大,会导致振荡频率偏移或无法起振;
  4. 等效串联电阻(ESR):250Ω,处于无源晶振的常规范围,需配合振荡电路的驱动能力(如MCU内部OSC模块),确保可靠起振;
  5. 频率稳定度:±20ppm,涵盖温度、电压波动等环境变化的影响,在工作温度范围内,频率偏移不超过该值,保证设备计时/通信稳定性。

三、环境适应性表现

该晶振适配工业级应用场景,环境性能如下:

  • 工作温度范围:-40℃~+85℃,可覆盖户外设备(如智能路灯、农业传感器)、工业控制板(PLC、变频器)的温变需求,无需额外散热/保温设计;
  • 抗干扰性:无源晶振固有特性使其对电磁干扰(EMI)敏感度低于有源晶振,适合复杂电磁环境(如工业车间);
  • 存储温度:兼容-55℃~+125℃(雅晶鑫同类产品常规参数),可应对短期极端温变。

四、典型应用场景

TAXM8M4RFDCET2T的规格适配以下场景:

  1. MCU/MPU时钟源:STM32、ATmega系列单片机的外部晶振,为系统提供基准时钟;
  2. 通信模块辅助时钟:蓝牙低功耗(BLE)、WiFi模块的校准计时(部分模块需外部8MHz晶振);
  3. 工业控制设备:PLC、传感器节点、变频器的控制电路时钟,满足宽温稳定运行;
  4. 消费电子:智能家电(洗衣机、空调控制板)、穿戴设备(智能手环低功耗计时);
  5. 车载电子(非极端场景):车载中控、行车记录仪的辅助时钟(适配-40℃~+85℃车内温变)。

五、选型与应用注意事项

  1. 负载电容匹配:必须外接12pF NP0材质电容(温度系数低),避免X7R材质(温度系数大,易偏移);
  2. ESR与驱动能力:若MCU内部OSC驱动弱(如低功耗MCU),需确认ESR匹配性,必要时加外部反相器驱动;
  3. 温度范围确认:若场景温度超85℃(如高温烤箱),需更换宽温(-40℃~+125℃)规格;
  4. 贴装兼容性:SMD3225-4P焊盘需符合IPC标准,贴装后可通过X-ray检测引脚虚焊。

综上,TAXM8M4RFDCET2T是一款性价比高、适配性强的无源贴片晶振,可满足多数工业与消费电子领域的时钟基准需求。

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
