EPSON X1A0001710001 无源晶振产品概述

一、产品核心定位

X1A0001710001是EPSON(爱普生)推出的32.768kHz无源音叉晶振,属于低频率计时基准类器件,采用无源设计(依赖外部振荡电路驱动),聚焦对时间精度、体积紧凑性有明确要求的电子设备,是消费电子、工业控制、物联网等领域的常用计时组件。

二、关键性能参数解析

1. 频率与精度

  • 基础频率:32.768kHz(2¹⁵次幂,天然适配1Hz分频,是实时时钟(RTC)、计时类应用的标准基准频率,无需复杂分频电路即可获得秒级信号);
  • 常温频差:±20ppm(即每百万份频率偏差不超过20份,换算为时间误差:每日约1.728秒,满足多数消费电子、工业计时的精度需求,无需额外温补即可覆盖常规场景)。

2. 负载电容与ESR

  • 标称负载电容:12.5pF(需与电路中两个串联电容匹配,总串联值接近12.5pF,避免频率偏移——实际设计中常用22pF×2电容(串联值≈11pF),或根据板级寄生电容微调);
  • 等效串联电阻(ESR):60kΩ(常规无源晶振水平,需匹配振荡电路的驱动能力,多数MCU内置RTC电路(如STM32、ESP32)可直接支持)。

3. 温度适应性

  • 工作温度范围:-40℃+105℃(覆盖工业级、部分车载级温度场景,优于消费级0℃70℃的常规范围,可稳定工作于户外设备、车载仪表盘等高低温环境)。

三、封装与贴装适配

  • 封装类型:SMD2012-2P(公制2.0×1.2mm,对应英制0805封装);
  • 引脚设计:2引脚贴片式,适合自动化SMT贴装,无额外引脚占用,体积紧凑适配小型化设备(如智能手环、蓝牙耳机);
  • 贴装工艺要求:回流焊峰值温度建议240~250℃,单次高温时间不超过10秒,避免热应力损坏晶振内部音叉结构。

四、典型应用场景

该晶振因低频率、宽温、小体积的特点,广泛应用于以下领域:

  1. 实时时钟(RTC)模块:MCU内置RTC的计时基准,确保设备断电后时间不丢失(如智能家居网关、工业PLC);
  2. 智能穿戴设备:智能手表、手环的计时功能,小封装适配穿戴产品的紧凑空间;
  3. 物联网(IoT)节点:低功耗传感器(温湿度、气体传感器)的定时唤醒,32.768kHz低功耗特性延长电池寿命(如户外环境监测节点);
  4. 车载电子:仪表盘时钟、胎压监测(TPMS)的定时数据发送,宽温满足车载-40℃~85℃的环境要求;
  5. 消费电子:计算器、遥控器、电子秤的计时功能,成本可控且性能稳定。

五、选型与使用注意事项

  1. 振荡电路匹配:需确认外部电路(或MCU内置振荡电路)的驱动能力满足60kΩ ESR,必要时串联1MΩ左右的反馈电阻增强起振;
  2. 负载电容匹配:晶振两端需各接一个电容到地,避免仅用单个电容导致频率偏移;
  3. 抗干扰设计:无源晶振抗干扰弱于有源晶振,需远离高频电路(WiFi、蓝牙模块),缩短晶振到MCU引脚的走线,必要时加屏蔽罩;
  4. 存储要求:建议存储在温度0℃~40℃、湿度≤60%的环境中,避免受潮影响性能。

六、产品优势总结

  • 品牌可靠性:EPSON晶振在计时领域的精度与稳定性有行业口碑,量产一致性高;
  • 宽温适配:-40℃~105℃覆盖多场景,无需额外温补即可满足工业/车载需求;
  • 小体积低成本:SMD2012封装适合小型化设备,无源设计比有源晶振成本低30%以上,适合量产;
  • 兼容性强:32.768kHz标准频率适配绝大多数MCU内置RTC电路,无需额外开发。

该产品是计时类应用的高性价比选择,可稳定满足从消费电子到工业场景的核心计时需求。

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
