XC53M4-8.000-F20NLDT 产品概述

XC53M4-8.000-F20NLDT 是杭晶(HCI)推出的国产化贴片金属谐振器,采用 SMD5032-4P 封装,标称频率 8.000 MHz。器件面向需要高可靠性、可追溯国产供应的嵌入式时钟源应用,兼顾体积、性能与产能优势。

一、主要特点

  • 国产化全流程生产,供应链可控,适合国产化替代方案。
  • 贴片金属外壳,SMD5032-4P(约 5.0 × 3.2 mm,4 引脚)小尺寸封装,便于自动贴片与回流焊装配。
  • 标称频率:8.000 MHz,适配 MCU、DSP、通信及时钟子系统。
  • 常温标称频差(25°C):±10 ppm,频率稳定度(全温域或指定条件下):±20 ppm。
  • 负载电容:20 pF(CL),设计用于并联谐振的标准负载条件。
  • 等效串联电阻(ESR):80 Ω(典型),利于稳态振幅与起振时间的评估。
  • 工作温度范围:-40°C ~ +85°C,满足工业级温度需求。

二、规格速览

  • 型号:XC53M4-8.000-F20NLDT
  • 品牌:HCI(杭晶)
  • 封装:SMD5032-4P(贴片金属外壳)
  • 频率:8.000 MHz
  • 负载电容(CL):20 pF
  • 常温频差(25°C):±10 ppm
  • 频率稳定度:±20 ppm
  • ESR:80 Ω
  • 工作温度:-40°C ~ +85°C

三、性能说明与电路建议

  • 负载电容匹配:为保证器件在电路中的实际频率接近标称值,应在晶体两端并联合适的负载电容。考虑到电路走线与封装的寄生电容(通常 2–5 pF),可按 CL = (C1·C2)/(C1+C2) + Cstray 的关系选择 C1、C2。若采用 C1 = C2 的配置,典型建议值在 18–22 pF 区间,需根据实际板上寄生电容微调。
  • 起振与 ESR:ESR 越低通常有利于快速起振,80 Ω 为该型号的等效阻抗指标,实际起振时间还受驱动电路增益与负载条件影响。
  • 驱动电平与谐波:遵循所用微控制器或振荡器 IC 的晶体驱动规范,避免过高驱动电平导致非线性或加速老化。
  • 装配工艺:SMD 封装适配常规回流焊流程;为保证可靠焊接,推荐遵循厂商提供的焊接曲线与贴装工艺要求(若需详细焊接参数,请向厂商索取工艺说明书)。

四、应用场景

  • 微控制器/微处理器系统的主时钟或外部晶体振荡器输入(8 MHz 常见于多种低功耗 MCU)。
  • 通信模块本振、串口时序基准、传感器采样控制与定时系统。
  • 工业控制、物联网终端、消费电子及需要国产化替代的电子产品。

五、封装与可靠性

  • SMD5032-4P 金属外壳结构,机械强度高,抗干扰性能优于开放式谐振元件。
  • 额定工作温度 -40°C 至 +85°C,适合多数工业与商业温度等级应用。
  • 国产化生产与质量控制,便于批量供应与长期一致性管理。

六、选型与注意事项

  • 确认目标电路的负载电容与驱动能力,按实际板级寄生电容调整外部并联电容以获得准确频率。
  • 若系统对频率稳定性或温漂有更高要求,可与供应商沟通是否提供更高等级的稳定度或温补方案。
  • 在进行环境应力测试(如温度循环、振动、回流)前,建议参考杭晶提供的详细规格书与可靠性测试报告。

XC53M4-8.000-F20NLDT 以其稳定的频率性能、小型封装与国产化供应链优势,适合在追求成本、可靠性与可追溯性的电子设计中作为 8 MHz 时钟源的优选元件。如需更详细的电气特性曲线、封装图纸或推荐焊接工艺,请联系杭晶(HCI)或其授权分销商获取完整版数据手册。

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
