TX32258M4DBDD2T 贴片晶振产品概述

TX32258M4DBDD2T是雅晶鑫(YJX)推出的一款通用型贴片石英晶振,采用SMD3225-4P封装,以8MHz基准频率为核心,兼顾稳定性与成本优势,广泛适配消费电子、工业控制等多领域的时钟源需求。

一、产品基本定位与品牌背景

该型号属于雅晶鑫通用工业级贴片晶振系列,主打“小体积、高稳定、易适配”三大特点,专为需要紧凑时钟源设计的电子设备开发。雅晶鑫(YJX)作为国内频率元件领域的成熟厂商,拥有10余年晶振研发与生产经验,产品通过RoHS、REACH等环保认证,覆盖从消费级到工业级的全场景频率元件供应,其晶振产品以“参数一致性好、抗干扰能力强”为核心竞争力,被众多中小微电子企业及OEM厂商选用。

二、核心性能参数详解

本型号的关键参数直接决定了其适配场景,具体如下:

  1. 基准频率与常温频差:8MHz(±10ppm)
    常温(25℃)下频率偏差不超过80Hz(8MHz×10×10⁻⁶),满足多数MCU、蓝牙芯片、传感器的时钟精度要求;若结合外部匹配电容优化,可进一步提升频率一致性。
  2. 负载电容:10pF
    工作时需匹配外部10pF电容(通常采用2个5pF电容并联),此参数设计平衡了振荡稳定性与电路复杂度,无需额外复杂匹配电路。
  3. 频率稳定度:±20ppm(-30℃+85℃)
    在全工作温度范围内,频率漂移不超过160Hz,覆盖常规室内(0℃40℃)、户外(-10℃50℃)及部分轻工业环境(-30℃85℃),满足多数设备的温度适应性需求。
  4. 等效串联电阻(ESR):250Ω
    串联等效电阻控制在250Ω以内,确保晶振易启动(无需额外驱动电路),且工作功耗低,适配低功耗MCU(如STM32L系列)等设备。
  5. 工作温度范围:-30℃+85℃
    超出消费级晶振的常规温度范围(0℃70℃),可满足户外设备、车载辅助系统(非严苛工况)等场景的温度要求。

三、封装与工艺特点

本型号采用SMD3225-4P封装(3.2mm×2.5mm×0.8mm),是目前主流的小型化贴片晶振封装之一,具备以下优势:

  • 自动化生产适配:四脚贴片设计兼容SMT(表面贴装技术)全流程,焊接良率高,适合大规模量产;
  • 抗干扰能力:封装内部采用真空封装+石英晶体谐振器设计,有效减少外界电磁干扰对频率的影响;
  • 机械可靠性:封装材料采用耐高温陶瓷,可承受回流焊高温(260℃/10s),焊接后无开裂风险。

四、典型应用领域

TX32258M4DBDD2T因参数均衡、成本可控,广泛应用于以下场景:

  1. 消费电子:智能手表、蓝牙耳机、智能家居控制器(如温控器、智能插座);
  2. 工业控制:小型PLC(可编程逻辑控制器)、传感器模块、电机驱动器;
  3. 通信模块:低功耗蓝牙(BLE)模块、Wi-Fi模块(辅助时钟)、LoRa网关;
  4. 车载辅助设备:行车记录仪、车载充电器(非安全关键部件)。

五、选型适配建议

  1. 匹配电路设计:需在晶振两脚各串联一个5pF电容(与负载电容10pF匹配),避免使用过高或过低电容导致频率偏移;
  2. 环境适配:若应用场景温度低于-30℃或高于85℃,建议选择雅晶鑫同系列工业级增强型型号(如TX32258M4DBDD3T,-40℃~+85℃);
  3. 精度需求:若需更高精度(如±5ppm),可选择同品牌8MHz高精度系列型号,需注意成本略有提升。

六、品质保障与合规性

雅晶鑫为该型号提供1年质保,所有产品均通过:

  • RoHS 2.0(无铅、无镉等有害物质);
  • REACH(SVHC高关注物质合规);
  • 符合IEC 60068-2系列环境试验标准(温度、湿度、振动测试)。

综上,TX32258M4DBDD2T是一款“性能够用、成本友好、适配性强”的通用贴片晶振,适合对频率精度和成本有平衡需求的电子设备设计。

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
