EPSON Q13FC1350049无源贴片晶振产品概述

一、产品核心定位与基本属性

Q13FC1350049是爱普生(EPSON) 推出的工业级无源贴片晶振,专为需要稳定32.768kHz时钟基准的电子设备设计。该产品采用SMD3215-2P封装(3.2×1.5mm超小型贴片),属于低功耗、高精度时钟器件,可覆盖-40℃~+85℃宽温范围,适配消费电子、工业控制、车载等多场景需求。

二、关键技术参数详解

1. 频率与频差

  • 标准频率:32.768kHz(实时时钟RTC、低功耗MCU的通用基准频率,1秒对应32768个周期,便于精准计时);
  • 常温频差:±20ppm(换算为时间误差约**±1.73秒/天**,满足多数设备的计时精度要求,无需额外温补即可实现稳定基准)。

2. 负载电容与ESR

  • 负载电容:6pF(无源晶振需外接匹配电容实现振荡,通常建议并联两个12pF电容(等效6pF),具体需结合电路振荡条件调整);
  • 等效串联电阻(ESR):70kΩ(属于无源晶振常规水平,ESR越低振荡越稳定,70kΩ可适配多数MCU的内置振荡电路,无需外部驱动)。

3. 工作温度范围

  • 温度范围:-40℃~+85℃(工业级宽温,可在户外低温、车载高温等恶劣环境下稳定工作,避免温度变化导致的频率漂移)。

三、封装与适用场景

1. 封装特点

SMD3215-2P为2引脚超小型贴片封装,尺寸仅3.2×1.5×0.8mm,支持自动化贴装(回流焊/波峰焊),可大幅节省PCB空间,适配智能手环、小型传感器等微型设备。

2. 场景适配性

  • 自动化贴装:适合批量生产,降低人工成本;
  • 小型化设计:满足穿戴设备、物联网节点等对尺寸敏感的应用;
  • 宽温环境:支持工业现场、车载电子等户外/高温场景。

四、性能优势与可靠性

  1. 品牌可靠性:爱普生作为晶振行业头部品牌,产品一致性高,批次间参数偏差极小;
  2. 低功耗特性:无源晶振无内置驱动,仅需外接振荡电路,配合MCU低功耗模式可实现微安级功耗;
  3. 长寿命设计:无源晶振无机械磨损部件,理论寿命可达10年以上,无需定期维护;
  4. 抗干扰能力:32.768kHz为低频信号,受高频电路干扰影响小,适合电磁环境复杂的工业场景。

五、典型应用领域

  1. 实时时钟(RTC)模块:MCU内置RTC、DS1307等时钟芯片的基准源;
  2. 消费电子:智能手表、手环、计算器、电子日历的计时核心;
  3. 工业控制:PLC、传感器节点、远程监测设备的时间同步;
  4. 车载电子:仪表盘时钟、车载音响、胎压监测系统的基准频率;
  5. 物联网设备:LoRa、蓝牙低功耗(BLE)模块的低功耗时钟基准。

六、选型与使用注意事项

  1. 负载电容匹配:必须外接与负载电容(6pF)匹配的电容,避免频率漂移(建议并联两个12pF陶瓷电容);
  2. 振荡电路选择:需配合MCU的XTAL引脚(而非EXTAL),选择串联振荡模式(无源晶振常规模式);
  3. 焊接规范:回流焊温度≤260℃(峰值),焊接时间≤10秒,避免高温损坏晶振内部石英晶体;
  4. 布局设计:晶振周边需远离高频电路(如WiFi、射频模块),减少电磁干扰;电容需靠近晶振引脚,缩短走线长度。

Q13FC1350049凭借稳定的精度、宽温适应性与超小封装,成为32.768kHz时钟基准的高性价比选择,可覆盖从消费电子到工业级的多类应用需求。

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
