CO32H4-25.000-33KDTSN 产品概述

一、产品简介

CO32H4-25.000-33KDTSN 为 HCI(杭晶)系列高精度晶振器,标准频率 25.000 MHz,采用 SMD 3225 封装(3.2 × 2.5 mm)、4 引脚 HCMOS 输出结构。该器件在常温时具有 ±10 ppm 的初始频差,整体频率稳定度可达到 ±15 ppm,适用于对时钟精度和长期稳定性有较高要求的电子系统。工作电压范围 2.5 V 至 3.3 V,工作电流典型值 10 mA,工作温度范围 -40 ℃ 至 +85 ℃,强调高精度与高可靠性的平衡设计。

二、主要参数(要点)

  • 频率:25.000 MHz
  • 常温频差:±10 ppm
  • 频率稳定度(含温度等效差):±15 ppm
  • 输出模式:HCMOS(4P)
  • 工作电压:2.5 V ~ 3.3 V
  • 工作电流:10 mA(典型)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SMD 3225-4P
  • 品牌:HCI(杭晶)
  • 型号升级:升级型号为 1532H-25.000K33DTSL(请在采购前确认兼容性与最终型号)

三、产品特点

  • 小尺寸封装:3225 尺寸利于高密度 PCB 布局,适合便携与空间受限设备。
  • 高精度与稳定性:常温频差 ±10 ppm、整体稳定度 ±15 ppm,满足通信、时钟同步及精密测量等场景的频率要求。
  • 宽电源范围:2.5 V 至 3.3 V 兼容多种低压数字平台。
  • 工业级温度范围:-40 ℃ 至 +85 ℃,适用工业与汽车电子附近环境(请按具体应用验证温度下频率漂移)。
  • HCMOS 输出:直接驱动数字逻辑输入,便于与 MCU、FPGA、通信芯片等连接。

四、典型应用

  • 通信设备时钟源(PHY、SERDES 附件时钟等)
  • 微控制器与 FPGA 系统时钟
  • 网络设备与交换机时钟同步
  • 精密计时与测量仪器
  • 消费类电子及工业控制设备

五、注意事项与建议

  • 电源去耦:建议在 VCC 与 GND 之间靠近器件放置 0.1 μF 陶瓷去耦电容以保证电源稳定,避免噪声影响输出洁净性。
  • PCB 布局:将时钟线尽量短且阻抗可控,远离大电流开关节点和高速差分对,减少串扰与抖动。
  • 引脚兼容性:已声明型号升级为 1532H-25.000K33DTSL。尽管升级型号在性能与封装上保持一致,建议在设计更换或批量采购前确认引脚定义与功能完全兼容。
  • 焊接与可靠性:遵循器件厂家的回流焊温度曲线与储存湿度控制建议,避免超过规定焊接温度造成性能退化。
  • ESD 与浪涌:HCMOS 输出对静电敏感,搬运与装配过程中应采取防静电措施。

六、结论

CO32H4-25.000-33KDTSN 面向需要稳定、高精度时钟源的中高端电子应用,兼顾小型化封装及工业级温度适应能力。若需批量替换或采用升级型号 1532H-25.000K33DTSL,建议与供应商确认技术文档与引脚图,以确保硬件设计的一致性与系统长期可靠性。若需要完整数据手册(电气特性曲线、时序图、封装尺寸与焊接规范),可联系 HCI(杭晶)或其授权分销商获取。

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
