EPSON X1A000161000116 无源晶振产品概述

一、产品核心定位与基本属性

EPSON X1A000161000116是一款针对实时时钟(RTC)、低功耗MCU系统设计的高精度低频无源晶振,核心频率为行业标准的32.768kHz。依托爱普生(EPSON)在晶振领域的成熟工艺,该产品具备高稳定性、宽温适应性等特点,广泛适配消费电子、工业控制、物联网终端等场景。

作为无源晶振,它无需内置驱动电路,仅需外接匹配电容即可工作,抗干扰能力优于有源晶振;同时采用SMD3215小体积封装,适合对空间敏感的便携设备。

二、关键电气参数及性能特点

该晶振的核心参数直接决定了应用场景的适配性,具体表现为:

(1)频率精度与稳定性

  • 常温频差±20ppm:常温(25℃左右)下,每天时间误差约±1.728秒(计算逻辑:24小时×3600秒/小时×1e6×20e-6=1.728秒),满足大多数消费电子(智能穿戴)、工业传感器节点的RTC精度需求;
  • 32.768kHz标准频率:该频率是RTC系统的“黄金频率”——通过15次2分频即可得到1Hz(秒信号),无需复杂分频电路,大幅降低系统设计成本。

(2)电气匹配与振荡可靠性

  • 负载电容12.5pF:无源晶振需外接两个匹配电容(串联在振荡电路两端),12.5pF是行业常见标准值,匹配电路简单(可参考datasheet选15pF左右外接电容,兼顾PCB寄生电容影响);
  • ESR(等效串联电阻)60kΩ:ESR是影响振荡可靠性的核心参数,60kΩ在同类型晶振中属于较低水平,可有效降低振荡电路的驱动门槛,避免因ESR过高导致停振。

(3)宽温工作范围

  • 工作温度-40℃至+105℃:覆盖工业级环境(户外传感器、车载辅助时钟)和高温消费场景(厨房智能设备),低温下仍能稳定振荡,无需额外温度补偿。

三、封装与典型应用场景

(1)封装规格

采用SMD3215贴片封装,尺寸仅3.2mm×1.5mm×0.8mm(长×宽×高),体积小巧,适合高密度PCB设计,尤其适配便携设备(智能手表、手环)、小型物联网模块。

(2)典型应用

  • 消费电子:智能穿戴(手表、手环)RTC、蓝牙耳机系统基准;
  • 工业控制:工业传感器节点(温湿度、压力传感器)时间戳、PLC辅助时钟;
  • 物联网终端:智能家居网关、智能门锁RTC模块;
  • 汽车电子:车载仪表盘辅助时钟(需确认具体车规认证,部分场景可适配)。

四、环境适应性与可靠性

爱普生X1A000161000116继承了品牌高可靠性特点:

  • 无铅环保:符合RoHS、REACH等国际标准,满足欧盟、北美市场准入要求;
  • 抗冲击振动:SMD封装结构紧凑,可承受常规运输、使用中的振动冲击(具体参数参考datasheet);
  • 长期稳定性:无源晶振老化率低(爱普生典型≤±5ppm/年),长期使用仍能保持精度。

五、选型与匹配注意事项

为确保正常工作,需注意:

  1. 负载电容匹配:根据12.5pF负载电容,选15pF/22pF外接电容(结合PCB寄生电容调整),避免频偏或停振;
  2. 焊接工艺:无铅封装回流焊温度需控制在260℃以内(峰值),避免过热损坏;
  3. 驱动能力确认:外接振荡电路(如MCU RTC模块)需满足驱动电流≥1μA,适配60kΩ ESR。

该晶振凭借高性价比与稳定性能,成为32.768kHz RTC场景的主流选型之一,适合对精度、体积、成本有综合要求的产品设计。

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
