XC32M4-50.000-F12NJDTL产品概述

一、产品简介

XC32M4-50.000-F12NJDTL为杭晶(HCI)全国产化贴片金属晶振,封装为SMD 3225-4P,基频50.000MHz。该器件为高可靠性、小体积的表面贴装振荡元件,针对工业级电子设备与高精度时钟源设计,常温标称频差±10ppm,典型等效串联电阻(ESR)40Ω,负载电容12pF,工作温度范围-40℃至+85℃,频率长期稳定性(含温度影响)控制在±20ppm范围内,适配多类晶体振荡器电路与高频时钟需求。

二、主要参数一览

  • 型号:XC32M4-50.000-F12NJDTL
  • 品牌:HCI(杭晶)
  • 频率:50.000 MHz
  • 封装:SMD 3225-4P(3.2×2.5mm,4Pads)
  • 负载电容:12 pF
  • 常温频差(初始容差):±10 ppm
  • 频率稳定度:±20 ppm
  • 等效串联电阻(ESR):40 Ω
  • 工作温度:-40 ℃ ~ +85 ℃
  • 工艺:贴片金属封装,全国产化

三、技术特点

  • 全国产化设计与制造,供应链可控,适合国产化替代场景。
  • 3225小尺寸金属封装,具有良好机械强度和热稳定性,利于SMT贴装与自动化生产。
  • 50MHz高频输出,适配高速数字系统与高速串行接口的时钟基准。
  • 12pF负载电容为常见值,方便与多数晶体振荡器或外部晶体管振荡电路配合使用。
  • ESR控制在40Ω,有利于匹配多数振荡器驱动级;设计时应考虑驱动器增益与负载匹配以确保启动裕度。
  • 宽工作温度范围满足工业级应用需求,频率稳定度±20ppm适用于对时钟精度有中高要求的系统。

四、典型应用场景

  • 工业控制与自动化设备的主时钟或子时钟源。
  • 网络通信设备、高速串行接口(如PCIe、USB、SATA等)参考时钟(视系统抖动要求而定)。
  • 测试与测量设备、示波器与信号分析仪时钟。
  • 微控制器(MCU)、FPGA、DSP等外部时钟输入应用。
  • 卫星通信、无线基站等需高稳定性本地振荡源的场景(结合系统抖动/相噪要求评估)。

五、封装与焊接建议

  • 推荐按厂商提供的3225封装PCB焊盘尺寸与过孔布局设计,保证焊盘与焊膏覆盖率一致以避免翘曲。
  • 贴装时采用回流焊工艺,严格控制温度曲线以保护封装与内部晶体结构(遵循厂商最高回流温度与时间)。
  • 焊接后建议进行XTAL焊点的清洗与干燥处理,避免残留助焊剂影响长期可靠性。
  • 布线要求:晶体与驱动器间走线尽量短,避免并行长线及靠近大电流回路。将接地面铺铜并在晶体附近做好局部接地过孔布局,以降低噪声耦合。

六、设计与选型注意事项

  • 负载电容匹配:器件标称12pF负载电容,实际电路中两侧并联电容应考虑PCB寄生电容与输入电容,计算并调整至等效12pF。
  • 驱动能力:ESR为40Ω时,需确保振荡器驱动级具有足够增益与启动能力;必要时可加入小阻抗串联或调整反馈网络以稳定振荡。
  • 温漂与频差:常温频差±10ppm为出厂校准值,若系统对温度影响敏感,应根据±20ppm频率稳定度评估系统补偿或温控需求。
  • 老化与可靠性:长时间使用中频率可能出现微量漂移,关键时钟应用建议做定期校准或使用外部校时手段(GPS、PTP等)。

七、结论与采购建议

XC32M4-50.000-F12NJDTL以其50MHz高频、3225小尺寸金属封装和工业级温度范围,适合对时钟精度与可靠性有中高要求的电子产品。采购时建议向杭晶(HCI)索取样品与数据手册,确认回流焊曲线与封装推荐尺寸,并在样机上完成启动裕度、相噪/抖动和温度稳定性验证后再批量应用。若有更高精度或更低相位噪声需求,可与供应商沟通定制或选型更高等级产品。

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
