- 频率稳定度（含温度影响）：±20ppm
- 负载电容（CL）：10pF
- 等效串联电阻（ESR）：40Ω
- 工作温度范围：-30℃ ~ +85℃
- 封装：SMD2520-4P（贴片四脚）
- 品牌：YJX（雅晶鑫）
- 产地：国产
三 关键特性与优势
- 高频稳定：40MHz 高频输出，适配高速 MCU、通信模块和射频前端参考时钟。
- 精度可控：常温±10ppm 初始精度，配合±20ppm 的频率稳定度，满足多数中高精度时钟需求。
- 小型化封装：SMD2520-4P 体积小、重量轻，兼容自动贴装与回流焊工艺。
- 可靠性良好：工作温度覆盖-30℃至+85℃，满足多数工业级及商业级应用环境。
四 典型应用
- 无线通信模块（Wi‑Fi、蓝牙、NB‑IoT等）参考时钟；
- 单片机/微处理器系统时钟源；
- 数字视频/音频设备、信号处理器时钟；
- 工业控制、仪表与测试设备中需要稳定参考频率的场合。
五 PCB 与焊接建议
- 负载电容：器件标称CL=10pF，设计时应考虑电路板寄生电容与器件引脚电容。通常在振荡器输入两侧添加耦合电容，每侧电容取值需在调试中校准（约8~12pF 为常见起点），以实现所需负载。
- 布局：晶振附近应留出地平面与良好接地回路，尽量缩短连线长度并避免与高速信号线交叉干扰。
- 焊接工艺：采用标准贴片回流工艺，遵循厂家回流曲线与清洗建议，避免机械应力与过热造成频率漂移或损坏。
- ESD 与储存：注意防静电保护与干燥储存，避免潮湿与污染影响长期可靠性。
六 选型与采购建议
在选型时，确认目标系统对频率初始偏差、温度稳定度及ESR的具体要求。如需更宽温度范围或更高稳定度，建议与供应商沟通定制或选择相应等级产品。采购时关注批次一致性与出厂校准报告，以保证大批量应用的一致性与可追溯性。
如需电路接入参考图、等效电路或样品测试数据，可联系供应商获取更详细技术资料。

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.
