YC8MBBCD2XT 产品概述
一、产品简介
YC8MBBCD2XT 为雅晶鑫（YJX）全国产贴片晶振，基准频率 8.000MHz，封装为 SMD3225-4P（3.2×2.5mm，四引脚结构）。此型号针对微控制器和精密计时应用设计，提供稳定的频率基准，适合对尺寸、成本和可靠性有要求的消费电子、工业控制与通信终端等领域。
二、主要技术参数
- 晶振类型：贴片晶振（SMD）
- 频率：8.000 MHz
- 常温频差：±10 ppm（室温基准）
- 负载电容：8 pF
- 频率稳定度（含温漂指标）：±20 ppm
- 等效串联电阻（ESR）：200 Ω（典型）
- 工作温度范围：-40 ℃ 至 +85 ℃
- 品牌：YJX（雅晶鑫）
- 封装：SMD3225-4P（3.2×2.5 mm）
三、产品特点与优势
- 全国产制造，供应链可控，适合国内大批量生产与长期项目支持。
- 小尺寸封装 SMD3225，利于多层板和高密度布局。
- 8 pF 负载设计适配多数低电容晶体振荡器电路，能够在较低负载下保持良好振荡起振性能。
- 频率精度与稳定度适中（常温±10ppm，总体±20ppm），能满足大多数 MCU、RTC 及通信模块的时钟需求。
- 工作温度覆盖工业级范围，可靠性适合-40~+85°C 的应用环境。
四、使用建议（匹配与振荡电路）
- 负载电容匹配：常用公式 C1 ≈ C2 ≈ 2×(C_L − C_stray)。以 C_L=8pF、PCB 与引脚寄生电容 C_stray≈2–3 pF 估算，推荐外接电容约 10–12 pF。实际取值请依据振荡器芯片手册与上板后测量微调。
- ESR 注意事项：200 Ω 的 ESR 对起振增益有影响，在低增益振荡器或要求快速起振的场合，需确认 MCU/振荡器驱动能力足够。若起振困难，可考虑更低 ESR 的器件或调整回路参数。
- 布局建议：晶振附近尽量避免大电流回路与高频干扰源，走地平面并缩短与振荡器芯片的连线，屏蔽与旁路电容靠近电源引脚。
五、焊接与可靠性注意
- 建议按厂商推荐的回流焊工艺进行焊接，避免长时间高温暴露与机械冲击。
- 贴片后清洗应选用对晶体无腐蚀、低残留的清洗工艺，避免使用强溶剂直接作用于器件主体。
- 存储与搬运避免受潮与强振动，长时间贮存前建议按供应商说明进行封装保存。
六、典型应用
- 8-bit/32-bit MCU 时钟源（工业与消费类控制板）
- 串口通信设备、调制解调器、无线模块的频率基准
- 工业测控、传感器节点与计时参考电路
七、采购与技术支持
如需样品、批量价格、封装带卷信息或更详细的电气特性曲线（温漂曲线、老化特性、起振时间等），请联系雅晶鑫（YJX）或指定代理商获取数据手册与检验报告。选型时建议与振荡器/MCU 芯片厂商的推荐值核对，完成上板测试以确保系统性能满足设计要求。
如需，我可根据您的振荡器芯片型号和电路板布局，给出更具体的匹配电容与布线优化建议。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
