CO32H4-20.000-33KDTSN 产品概述

一、产品核心定位

CO32H4-20.000-33KDTSN是杭晶(HCI)推出的工业级高稳定HCMOS输出晶振,以20MHz为标称频率,兼顾精度、稳定性与小型化设计,适配对频率一致性要求较高的数字系统。产品依托杭晶成熟的晶振制造工艺,在宽温范围内保持可靠的频率输出,可满足工业控制、通信等领域的多样化需求,是替代传统晶振的高性价比方案。

二、关键性能参数解析

1. 频率精度与稳定度

  • 标称频率:20MHz(主流通用频率,适配多数数字芯片时钟输入);
  • 常温频差:±10ppm(20℃环境下,频率偏差≤200Hz),保证上电后初始频率的一致性,避免系统启动阶段的时钟误差;
  • 全温稳定度:±25ppm(-40℃~+85℃范围),可有效抑制温度变化对频率的影响,即使在极端温度下,频率漂移仍控制在系统可接受范围内,避免通信中断、计时偏差等问题。

2. 输出与电气特性

  • 输出模式:HCMOS输出,兼容主流数字电路(MCU、FPGA、DSP等),无需额外电平转换电路,简化系统设计;输出驱动能力强,抗干扰性能良好,可直接驱动多通道时钟输入;
  • 供电参数:工作电压3.3V(低压主流规格,适配低功耗系统),工作电流10mA(兼顾性能与功耗,适合对电流敏感的便携式设备);

3. 封装规格

采用SMD3225-4P(3.2mm×2.5mm贴片封装,4引脚),体积小巧,比传统DIP封装缩小约60%,适配高密度PCB设计,支持回流焊工艺,焊接兼容性强。

三、封装与工艺特点

1. 小型化设计

SMD3225-4P封装尺寸仅3.2×2.5mm,可有效降低系统体积,适合便携式设备、小型化模块(如智能传感器、微型控制器)等场景,满足设备轻薄化趋势。

2. 工艺可靠性

  • 采用杭晶自研高精度石英晶体谐振器,谐振频率一致性好,长期老化漂移低(符合工业级产品要求);
  • 引脚对称布局设计,减少电磁干扰(EMI),提升系统抗干扰能力,避免时钟信号受外部噪声影响;
  • 封装材料耐高温(符合无铅回流焊温度曲线要求),可通过自动化焊接流程,降低生产难度与成本。

3. 稳定性保障

产品经过杭晶严格的可靠性测试(高低温循环、振动、冲击等),确保在复杂环境下长期稳定工作,避免因晶振失效导致系统故障。

四、环境适应性设计

产品支持**-40℃~+85℃**的工业级工作温度范围,可在户外、工业现场等恶劣环境下稳定运行:

  • 低温场景(如北方户外设备、冷库控制系统):频率漂移仍控制在±25ppm以内,不影响系统功能;
  • 高温场景(如车间控制柜、车载电子):避免因温度过高导致晶振频率失稳,保证通信与控制精度;
  • 抗振动/冲击:适配振动环境(如工业机械、车载行驶),避免晶振因振动出现频率跳变。

五、典型应用场景

1. 工业控制领域

PLC(可编程逻辑控制器)、工业传感器、伺服驱动器等,需稳定时钟信号保证控制精度与通信可靠性;

2. 通信设备

路由器、交换机、无线AP、户外基站等,20MHz频率适配多种通信芯片时钟需求,宽温设计满足户外场景;

3. 消费电子

智能家居设备(智能网关、摄像头)、便携式医疗仪器(血糖监测仪、小型心电图机),小型化封装适配设备轻薄化趋势;

4. 车载电子

车载信息娱乐系统、ADAS辅助驾驶模块(非安全关键场景),宽温设计适配车内温度变化(-20℃~+85℃常见)。

CO32H4-20.000-33KDTSN凭借高稳定、小型化、宽温适应性等特点,成为多领域数字系统时钟源的优选方案,可有效提升系统可靠性与设计效率。

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
