YC8MKBCD2XT 产品概述

一、产品简介

YC8MKBCD2XT 为雅晶鑫(YJX)推出的贴片晶振,标准频率为 8.000 MHz,采用 SMD3225-4P(3.2 × 2.5 mm,四端子)封装,面向空间受限且对频率精度与稳定性有较高要求的电子系统。该器件具有较小体积、良好温度范围和低等效串联电阻,适用于各种微控制器(MCU)和时钟电路的振荡源。

二、主要性能参数

  • 品牌:YJX(雅晶鑫)
  • 型号:YC8MKBCD2XT
  • 晶振类型:贴片晶振(四端子 SMD)
  • 频率:8.000 MHz
  • 常温频差(Initial Tolerance @25℃):±10 ppm
  • 频率稳定度(在工作温度范围内典型):±20 ppm
  • 负载电容:18 pF
  • 等效串联电阻(ESR):200 Ω(典型/最大)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SMD3225-4P(3.2 × 2.5 mm,四端子)

三、产品特点

  • 紧凑封装:SMD3225-4P 小型化设计,适合高密度 PCB 布局与便携设备应用。
  • 精度与稳定:常温±10 ppm 的初始精度,配合 ±20 ppm 的温度稳定度,在多数嵌入式与通信场景下可满足时钟同步与计时需求。
  • 工业级温度范围:-40 ℃ 到 +85 ℃,覆盖一般工业与户外电子设备工作环境。
  • 可靠的电气特性:ESR 200 Ω,在与多数 MCU 或振荡器电路配合时能实现可靠起振(但建议按具体 MCU 要求确认可接受的 ESR 范围)。
  • 标准化封装,便于自动贴装与回流焊接,提高生产效率。

四、典型应用场景

  • MCU 时钟源(低功耗单片机、8/16/32 位微控制器)
  • 实时时钟(RTC)参考频率(需配合时钟电路设计)
  • 通信模块(无线模块、有线接口)
  • 工业控制、传感器节点与物联网终端
  • 仪器仪表与消费类电子产品的频率基准

五、使用建议与注意事项

  • 负载电容配置:晶振标称负载电容为 18 pF。若采用对称双电容(C1 = C2 = C),则实际单侧电容近似满足公式 C ≈ 2 × (C_L - C_stray)。考虑 PCB 板迹和引脚寄生电容 C_stray ≈ 2–5 pF,建议常用 C 值约 27 pF(可在 22–33 pF 范围内按实际电路调试)。
  • 起振与 ESR:ESR 为 200 Ω,某些驱动能力较弱的振荡器电路可能需要评估起振时间与起振可靠性。建议在原型阶段验证 MCU/振荡电路的起振性能。
  • 布局建议:将晶振放置于 MCU 或振荡器输入端的最短距离内,走线对称且尽量短,避免在晶振与驱动器之间放置过多过孔或其他元件;在两端电容与晶振之间保持良好接地,减少噪声耦合。
  • 焊接工艺:兼容常用 SMT 回流焊流程。回流温度与曲线应符合制造工艺规范,避免过度热循环导致件性能退化。
  • 机械应力:避免在芯片上方施加额外机械应力或在焊接后进行过度机械加工,以免影响频率稳定性和长期可靠性。

六、封装与选型提示

  • 封装类型:SMD3225-4P(四端子),建议参考厂方外形尺寸与 PCB 推荐焊盘图进行布局。
  • 选型要点:确认 MCU 或振荡器的允许 ESR 范围、所需负载电容与频率精度要求;对温度稳定性、老化与长期漂移有更高要求的场合,应与供应商确认更详细的测试数据或选择更高等级产品。

七、订购信息与支持

  • 订货型号:YC8MKBCD2XT(8MHz, 18pF, ±10ppm 初始, -40~+85℃)
  • 品牌:YJX(雅晶鑫)
  • 推荐在样机阶段先小批量验证起振及稳定性,再进行批量采购。需要更多技术支持、样品或封装图纸,可联系雅晶鑫销售或技术团队获取详尽的规格书与 PCB 布局建议图。

本产品面向对体积、成本与性能有平衡需求的设计,适配广泛的嵌入式与工业应用。在设计与调试阶段建议依据实际电路条件优化负载电容与布线,确保可靠起振与长期稳定运行。

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
