T201648MFBDE2X 产品概述
一、产品简介
T201648MFBDE2X 是雅晶鑫（YJX）推出的一款国产超小型贴片晶振，面向对体积、厚度和频率精度有严格要求的电子产品。该器件采用 SMD2016-4P 封装，超薄设计，适合空间受限的移动终端、可穿戴设备、物联网节点及高密度 PCB 布局。
二、主要参数
- 晶振类型：贴片晶振（SMD）
- 标称频率：48 MHz
- 常温频差：±10 ppm
- 频率稳定度：±30 ppm
- 负载电容：12 pF
- 等效串联电阻（ESR）：40 Ω
- 工作温度范围：-30 ℃ ~ +85 ℃
- 封装：SMD2016-4P
- 品牌：YJX（雅晶鑫）
三、核心优势
- 超小超薄：SMD2016-4P 封装为高密度 PCB 设计节省空间并降低厚度堆叠。
- 高精度：常温 ±10 ppm 的初始误差与 ±30 ppm 的整体稳定度使其适用于对时钟精度有较高要求的系统。
- 兼容性好：48 MHz 常见于 MCU、通信模组和射频前端，便于替换与集成。
- 国产供货：供应链可控，有利于量产稳定性和交期管理。
四、典型应用场景
- 可穿戴设备与智能手表：对体积与功耗敏感、需高精度时钟的场合。
- 物联网终端与传感器节点：稳定的频率输出有利于通信与同步控制。
- 工业控制与嵌入式系统：在-30℃~+85℃环境下保持可靠工作。
- 无线通信模块与时钟参考：作为本振或时钟源使用。
五、封装与安装建议
- 建议将晶振尽量靠近目标芯片的时钟引脚布局，缩短信号走线以降低寄生电感与杂散电容。
- 负载电容设计时应考虑 PCB 杂散电容，常用计算经验为：C1 ≈ C2 ≈ 2×CL - Cstray（Cstray 包括器件引脚与走线的寄生电容），以获得接近标称的负载条件。
- 保持晶振周边地平面完整，避免高速信号线穿过晶振回流区，减小干扰。
- 焊接工艺按无铅回流曲线控制，避免过热或过长时间的回流温度暴露。
六、品质与可靠性
雅晶鑫作为国产品牌，对封装一致性与出厂筛选有较严格的管控。产品适用于商业和工业级温度范围，ESR 40 Ω 的设计兼顾启动性能与能耗。建议在关键应用中进行实际电路验证与老化测试，以确认长期稳定性。
七、选型建议与注意事项
- 若系统对频率精度要求更高（长期漂移或更宽温度范围），建议与供应商沟通是否有更严格稳定度或温度补偿方案。
- 在高速或精密时序应用中，评估晶振的相位噪声与启动时间（如需）以确保满足系统指标。
- 大批量采购可与厂商确认包装方式、出货周期与质量放行标准。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
