XC322520MOB4SA-18 产品概述

一、产品简介

XC322520MOB4SA-18 是扬兴科技(YXC)推出的一款高稳定性贴片无源晶振,标称工作频率为 20.000MHz。器件采用 SMD3225-4P 封装(3.2 × 2.5 mm),适用于体积受限且对频率精度有较高要求的电子设备。该晶振在常温(25℃)下的初始频差为 ±10ppm,额定负载电容为 12pF,整体频率稳定度(含温度漂移等)为 ±80ppm,工作温度范围宽至 −40℃ 至 +125℃,可满足工业级环境应用需求。

(注:未在此列出的如等效串联电阻(ESR)、并联电容等详参原厂完整数据手册。)

三、产品特性

  • 小型化封装,适合集成密集型 PCB 设计;
  • 优良的温度和频率稳定性,支持工业级温度范围;
  • 低功耗系统中可与各种无源振荡器电路或 MCU 内置振荡电路配合使用;
  • 标准化封装与引脚布局,便于自动贴装与回流焊接生产;
  • 品质可靠,适合量产和长期供货。

四、典型应用场景

  • 工业控制与自动化设备;
  • 通信设备中的时钟源(如射频模块、基带处理);
  • 微控制器与数字系统(作为外部时钟源);
  • 测试与测量仪器;
  • 汽车电子(需验证符合汽车级可靠性要求);
  • 物联网终端、智能终端及消费电子中要求高精度时钟的场合。

五、封装与机械说明

SMD3225-4P 为表面贴装封装,外形尺寸 3.2 × 2.5 mm,适配常见 3225 焊盘布局。焊盘建议按厂商推荐尺寸设计,以保证良好焊接强度与热传导。器件厚度与引脚位置请以原厂机械图纸为准,以免因尺寸误差影响贴装与焊接质量。

六、PCB 布局与焊接建议

  • 无源晶振需配合两只串联到地的负载电容;若两电容相等,建议按公式 C ≈ 2×(CL − Cstray) 选择,通常 Cstray 取 2–5 pF;
  • 晶振应靠近 MCU/振荡器输入管脚布局,信号走线尽量短且避免穿过分割地或噪声源;
  • 加强地平面、减少附近高速信号干扰,避免机械应力传递到晶振引脚;
  • 推荐采用标准回流焊工艺,遵循厂商给出的温度曲线;回流峰值温度和保温时间应与封装承受能力匹配。

七、可靠性与测试

产品通过常规出厂电气测试与频率筛选,建议在设计初期与样品阶段进行下列验证:温度循环测试、振动与冲击测试、湿热与回流耐受测试。对关键应用(如汽车、医疗),应与厂商确认是否满足相应认证与更严格的可靠性要求。

八、订购与使用注意事项

  • 下单时请注明完整型号(XC322520MOB4SA-18)与批次要求;
  • 在设计使用前,请参阅扬兴科技官方数据手册获取完整电气参数、等效电路、封装图与回流曲线;
  • 因为为无源晶振,必须配合适当的振荡器电路或微控制器振荡器输入使用;关注驱动电平与负载电容匹配以确保稳定振荡与频率精度;
  • 存储与搬运注意防潮与防静电,避免器件受潮或机械损伤。

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
