XC322525MOB4SA-18 产品概述

一、产品简介

XC322525MOB4SA-18 是 YXC(扬兴科技)推出的一款贴片无源晶体谐振器,封装为 SMD3225-4P(尺寸 3.2 × 2.5 mm)。工作频率为 25.000 MHz,常温初始频差 ±10 ppm,额定负载电容为 12 pF,整体频率稳定度 ±80 ppm(在工作温度范围内的典型表现)。器件工作温度范围广,从 -40℃ 到 +125℃,适合各种工业级与消费级应用场景。

二、主要特性

  • 无源晶振,需配合振荡器电路(如 CMOS/TTL 晶体振荡器芯片)使用
  • 频率:25.000 MHz
  • 常温初始频差:±10 ppm(25℃)
  • 负载电容:12 pF(标称)
  • 频率稳定度:±80 ppm(在 -40℃ 至 +125℃ 范围内的常用规格描述,具体请参考数据手册)
  • 工作温度范围:-40℃ ~ +125℃
  • 封装:SMD3225-4P(3.2 × 2.5 mm)
  • 品牌:YXC 扬兴科技

三、典型应用

  • 微控制器/微处理器晶振时钟源
  • 通信设备(射频前端/数字基带时钟)
  • 嵌入式系统和工业控制器
  • 网络设备(参考时钟)
  • 测试与测量仪器以及其他需要 25 MHz 精确时钟的场合

四、使用与电路注意事项

  • 配合无源晶振使用时,通常需在两端接入两只接地电容(C1、C2),形成典型 Pierce 振荡电路。负载电容 CL 与两侧电容的关系为: CL = (C1 × C2) / (C1 + C2) + Cstray 其中 Cstray 为PCB走线与封装等寄生电容(典型 2–5 pF)。
    例如:若 CL = 12 pF,假设 Cstray ≈ 3 pF,则可选择 C1 ≈ C2 ≈ 22 pF(具体取值应在实际板上测量寄生后调整)。
  • 为获得最佳频率稳定性与起振性,建议遵循振荡器芯片厂商推荐的外围元件与电路拓扑。
  • 供电与地的布线要尽量短、粗并做良好去耦,避免电源噪声耦合到振荡回路。
  • 对于较高精度要求,注意晶振的装配应远离高频功率电路、切换噪声源和大电流回流路径。

五、封装与安装建议

  • SMD3225-4P 小尺寸贴片封装,适合自动贴装与回流焊工艺。请按行业标准的回流焊曲线及器件供应商建议进行焊接。
  • 装配时注意防静电防潮处理,出厂通常会有干燥剂与密封包装,开封后按建议时间回流焊并尽快使用。
  • PCB 布局建议:晶振两端引脚对应的地平面应完整、短路迹接地;避免在晶体周围走高频信号线和大电流回流线;为减少寄生电容,信号垂直跳线和过孔尽量减少。

六、可靠性与质量控制

  • 选用工业级工作温度(-40℃ ~ +125℃),适合严苛环境下长期工作。
  • 频率稳定度(±80 ppm)涵盖温度漂移与典型老化影响,但最终性能与实际使用环境、焊接工艺及电路匹配有关。建议在产品设计验证阶段进行实测,以确认系统级频率误差与温漂满足要求。
  • 生产与出货前建议参考 YXC 数据手册中的测试条件与质量保证条款,按需索取加速老化与可靠性测试报告。

七、选型与采购建议

  • 若系统对初始频差、温漂或长期老化有更高要求,请在选型阶段联系供应商确认可提供的更高等级(如更低初始频差或更窄稳定度范围)的型号或校准服务。
  • 采购时请确认完整的型号:XC322525MOB4SA-18,并注明包装形式(卷盘、托盘等)、存储条件与交付批次,以便追溯与批次一致性控制。

八、小结

XC322525MOB4SA-18 是一款尺寸小、适应温度范围宽、适用于工业级应用的 25 MHz 无源贴片晶振。其 ±10 ppm 的常温初始频差和 12 pF 的负载电容规格,使其在需要稳定时钟源的小型化系统中具有良好的适配性。为确保系统性能,请重视 PCB 布局、电容匹配和焊接工艺,并在设计验证阶段进行频率与稳定性测试。若需更详细的电气参数、机械尺寸及测试条件,请参阅 YXC 扬兴科技提供的产品数据手册或联系技术支持。

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
