FC-135 32.7680KA-AG3 32.768kHz SMD晶振产品概述

一、产品定位与核心设计目标

FC-135 32.7680KA-AG3是爱普生(EPSON)推出的工业级小型化SMD晶振,专为需要高精度、宽温适应性的实时时钟(RTC)及低频计时场景设计。其核心设计围绕「小封装、低功耗、稳定振荡」展开,兼顾消费电子与工业应用的兼容性,是替代传统插件晶振的主流选型之一。

二、基础电气参数详解

该晶振的关键参数直接决定了应用适配性,具体如下:

  1. 标准频率与精度:输出频率为32.768kHz(RTC领域全球通用标准频率),常温(25℃)下频差为±20ppm。换算为实际频率误差仅±0.655Hz,可满足大多数设备「秒级计时精度」需求,无需额外温补电路即可实现基础高精度计时。
  2. 负载电容匹配:额定负载电容为7pF,设计电路时需确保外接电容(通常2个3.5pF并联)与负载电容匹配,避免频率偏移。该参数简化了外围电路设计,降低系统成本。
  3. 等效串联电阻(ESR):典型ESR为70kΩ,在32.768kHz低频晶振中属于合理范围——ESR越低振荡越稳定,但过高会增加功耗;70kΩ平衡了稳定性与功耗,适合电池供电的低功耗设备。
  4. 工作电压范围:覆盖1.8~3.3V主流MCU电压区间,无需额外电压转换电路,适配大多数嵌入式系统。

三、封装与机械特性

FC-135采用2-SMD无引线封装(无引脚设计),尺寸约1.6mm×1.0mm×0.5mm(长×宽×高),属于超小型封装。无引线设计具有三大优势:

  • 贴装兼容性强:支持回流焊工艺,可与主流SMT生产线适配,量产效率高;
  • 空间利用率高:适合智能穿戴、物联网节点等小型化产品,不占用额外PCB面积;
  • 抗干扰性好:无引脚减少电磁干扰路径,提升振荡稳定性,降低误触发风险。

四、环境适应性与可靠性

该晶振的环境参数覆盖宽温与工业级要求:

  1. 工作温度范围:-40℃~+85℃,可满足车载电子(仪表盘、车载终端)、工业控制(PLC、传感器)等场景的极端温度需求;
  2. 存储温度:-55℃~+125℃,确保运输与存储过程中的可靠性;
  3. 环保与寿命:符合RoHS、REACH等环保标准,典型寿命≥10年,适合量产设备的长期稳定运行。

五、典型应用场景

FC-135的参数特性使其适配多种低频计时场景:

  1. 实时时钟(RTC)模块:如MCU内置RTC、独立RTC芯片(DS3231等)的时钟源,满足电子钟、智能家居网关的计时需求;
  2. 智能穿戴设备:智能手表、手环的时间同步与低功耗计时,小封装与宽温特性适配佩戴环境的温度变化;
  3. 物联网(IoT)节点:传感器节点、低功耗蓝牙设备的时间戳与休眠唤醒计时,低ESR确保户外/工业场景稳定;
  4. 车载电子:仪表盘时钟、车载信息娱乐系统的时间源,-40℃~+85℃宽温覆盖车载环境的温度波动;
  5. 工业控制设备:PLC、计时器、工业传感器的计时模块,满足工业级环境的可靠性要求。

六、品牌与选型优势

作为爱普生晶振系列的一员,FC-135具有明显的品牌优势:

  • 一致性好:爱普生生产工艺成熟,批量产品参数偏差极小,无需额外筛选;
  • 技术支持完善:提供详细datasheet与应用手册,帮助工程师快速完成电路设计;
  • 供应链稳定:作为全球知名晶振供应商,产能充足,适合大规模量产需求。

综上,FC-135 32.7680KA-AG3凭借「小封装、高精度、宽温适应性」的特点,成为消费电子、工业控制、物联网等领域的高性价比选型。

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
