HCI CO32H4-50.000-33KDTSN 晶体振荡器产品概述

杭晶电子(HCI)推出的CO32H4-50.000-33KDTSN是一款小型化宽温HCMOS输出晶体振荡器(XO),针对工业控制、通信设备、物联网终端等场景设计,兼顾高精度、低功耗与可靠性,适配3.3V系统供电。

一、产品定位与核心特性

该产品以50MHz标准频率为核心,针对中高精度时钟同步需求优化,核心特性包括:

  • 常温频差±10ppm,满足常规工业/消费类系统的时钟精度要求;
  • 工作温度范围覆盖-40℃~+85℃,适应户外、车载(非汽车级)等宽温环境;
  • 3.3V单电源供电,典型工作电流10mA,低功耗设计适配电池供电设备;
  • SMD3225-4P超小封装(3.2mm×2.5mm),节省PCB空间,适合高密度布局;
  • HCMOS输出兼容TTL/CMOS逻辑电平,输出波形稳定,抗干扰能力强。

二、关键参数详解

2.1 频率特性

  • 标称频率:50.000MHz(±10ppm常温频差,即25℃下频率偏差≤500Hz);
  • 工作温度稳定度:-40℃~+85℃范围内,频率偏差≤±25ppm(即1.25kHz以内),满足宽温环境下的时钟稳定性;
  • 长期老化率:≤±5ppm/年,确保长期使用中频率漂移可控,适配需要稳定时钟的设备。

2.2 输出特性

  • 输出模式:HCMOS(高电平≥2.4V,低电平≤0.4V,完全兼容3.3V TTL/CMOS逻辑);
  • 输出负载:默认匹配15pF容性负载(典型值),输出上升/下降时间≤10ns,方波占空比50%±5%;
  • 输出启动:无外部使能引脚,上电后10ms内输出稳定时钟,无需额外配置。

2.3 电源特性

  • 工作电压:3.3V±5%(实际可用范围2.97V~3.63V),适配主流3.3V系统设计;
  • 工作电流:典型值10mA,最大值12mA,轻负载下功耗低至33mW,适合电池供电的物联网设备;
  • 电源抗扰:电源纹波≤100mV时,频率偏差≤±1ppm,对电源噪声不敏感,减少滤波成本。

2.4 封装与引脚配置

  • 封装类型:SMD3225-4P(表面贴装,尺寸3.2×2.5×0.8mm),符合IPC-J-STD-020焊接标准;
  • 引脚定义(常规4引脚配置): 1脚:VCC(电源输入); 2脚:GND(地); 3脚:NC(空脚,无功能); 4脚:OUT(时钟输出);
  • 焊接要求:回流焊温度≤260℃(峰值),焊接时间≤10s,避免烙铁直接接触封装。

三、典型应用场景

该产品因宽温、小封装、低功耗特性,广泛适用于:

  1. 工业控制设备:PLC、变频器、传感器模块(-40~85℃环境下稳定工作);
  2. 通信终端:路由器、交换机、无线AP(50MHz用于射频前端时钟同步);
  3. 物联网设备:智能网关、传感器节点(低功耗适配电池供电);
  4. 消费电子:平板、智能电视、机顶盒(小封装节省PCB空间)。

四、可靠性与环境适应性

HCI对该产品进行了严格可靠性测试,满足:

  • 环境测试:存储温度-55℃+125℃,振动测试10g(202000Hz),冲击测试1000g(1ms);
  • 环保要求:符合RoHS 2.0标准,无铅焊接,适配绿色制造需求;
  • 寿命:平均无故障时间(MTBF)≥10^6小时,长期使用可靠性高。

五、选型与使用注意事项

  1. 负载匹配:根据实际电路负载调整输出端匹配电容(建议15pF±10%);
  2. 电源滤波:在VCC引脚串联10Ω电阻+0.1μF陶瓷电容滤波,抑制电源噪声;
  3. 焊接防护:采用回流焊工艺,避免烙铁直接接触封装,防止热损坏;
  4. 静电防护:操作时佩戴防静电手环,使用离子风扇,避免静电击穿。

该产品平衡了精度、尺寸与成本,是中低端时钟同步场景的高性价比选择,可直接替换同类3225封装50MHz XO产品。

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
