EPSON Q24FA20H00687 无源贴片晶振产品概述

Q24FA20H00687是日本爱普生(EPSON)推出的一款通用型无源石英贴片晶振,针对中低端电子设备的频率基准需求设计,平衡了精度、体积与成本,适合工业控制、消费电子、物联网等领域的批量应用。

一、产品基本定位

该晶振属于无源晶振范畴,无内置驱动电路,依赖外部MCU或ASIC的振荡电路实现谐振。核心定位是小体积、工业级温度范围、通用精度的频率源,可替代同规格进口/国产晶振,满足大部分电子设备对12MHz基准频率的刚性需求,尤其适合对成本敏感但要求稳定性能的批量项目。

二、核心参数深度解析

1. 频率与精度指标

  • 标称频率12MHz:是MCU、无线模块的主流基准频率(如STM32F1/F4系列、CC2530蓝牙模块均常用此频率),适配性强;
  • 常温频差±10ppm:换算为频率偏移量120Hz(12MHz×10×10⁻⁶),可满足串口通信(波特率精度要求±1%以内)、定时器计时等基本功能,无需额外校准;
  • 全温频率稳定度±30ppm:在-40℃~+85℃范围内,最大频率偏移360Hz,覆盖工业级设备的温度波动场景,无需温度补偿即可稳定工作。

2. 谐振与匹配参数

  • 负载电容10pF:是晶振与外围电路的关键匹配参数,实际应用需在引脚与地间并联两个电容(如15pF+15pF并联,或单电容调整),总容量接近10pF,否则会导致频率偏移或无法起振;
  • 等效串联电阻(ESR)150Ω:属于无源晶振常规水平,主流MCU(如STM32)的晶振驱动能力可轻松覆盖,保证稳定起振。

3. 环境适应性

  • 工作温度-40℃~+85℃:符合工业级标准,适配户外终端、车载辅助设备等温差较大场景;
  • 存储温度-55℃~+125℃:满足电子设备常规存储要求,不易因温度变化导致性能下降。

三、封装与物理特性

采用SMD2520-4P封装,具体参数:

  • 尺寸:2.5mm×2.0mm×0.7mm(长×宽×高),小型化设计节省PCB空间,适合高密度布局;
  • 引脚:4引脚无突出,支持SMT自动化焊接,焊接兼容性好;
  • 重量:约0.02g,轻量化适配便携设备(智能手环、蓝牙耳机);
  • 环保认证:符合RoHS、REACH标准,无铅焊接,满足欧盟市场准入要求。

四、典型应用场景

结合参数特性,主要应用于:

  1. 工业控制模块:PLC输入输出模块、电机控制器、传感器节点(工业级温度范围适配现场环境);
  2. 消费电子:智能穿戴(手环、手表)、小家电(智能电饭煲、加湿器)、蓝牙音箱(小体积需求);
  3. 物联网终端:低功耗蓝牙(BLE)模块、WiFi模块、智能门锁(12MHz基准适配主流无线芯片);
  4. 车载辅助设备:车载充电器、行车记录仪(工业级温度范围适配车载温差)。

五、应用注意事项

为保证稳定工作,需注意:

  1. 负载电容匹配:严格按10pF设计外围电路,避免频率偏移;
  2. 布局优化:晶振靠近MCU引脚,走线≤10mm,远离高频信号线(SPI、I2C)减少干扰;
  3. 焊接温度控制:回流焊温度≤260℃,焊接时间≤10秒,避免过热损坏石英晶体;
  4. ESR匹配:若MCU驱动弱,可加10kΩ~100kΩ电阻提升驱动能力。

该晶振凭借爱普生工艺稳定性,批量应用一致性高,是通用频率基准的可靠选择,适合对成本敏感但要求基本精度与工业级温度范围的电子设备。

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.

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
