Q24FA20H00209是爱普生(EPSON)推出的无源贴片石英晶振,属于SMD2520封装系列的高性价比产品。该晶振以40MHz为核心频率基准,兼顾精度、稳定性与环境适应性,主要面向需要小尺寸、工业级温度范围的电子设备设计,是主流MCU、FPGA、传感器等模块的理想时钟源组件。
频率精度与稳定性
常温频差为±10ppm,换算为实际频率误差仅400Hz(40MHz×10×10⁻⁶),满足大多数工业控制、物联网设备对频率基准的精度要求。其频率稳定性在-40℃~+85℃范围内保持一致,避免极端温度下的时钟漂移,确保系统时序准确性。
负载电容与电路适配
标称负载电容为9pF,与主流微控制器(如STM32、ESP32)的时钟输入引脚负载匹配度高,无需额外复杂的电容调整,简化电路设计流程,降低研发成本。
等效串联电阻(ESR)
ESR为40Ω,处于该封装尺寸下的优良水平。低ESR可降低谐振损耗,提升振荡信号的幅值与纯度,减少杂波干扰,保证系统时钟的可靠性,避免因信号衰减导致的功能异常。
工作温度与环境适应性
覆盖-40℃至+85℃的工业级温度范围,可稳定工作于严寒、高温等恶劣环境,适用于户外监测设备、工业自动化模块、车载辅助系统等场景,无需额外温度补偿即可满足性能要求。
Q24FA20H00209采用SMD2520-4P封装,具备以下优势:

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
