EPSON Q13MC30610004 无源石英晶振产品概述

一、产品基础信息

Q13MC30610004是日本爱普生(EPSON)推出的无源石英晶振,隶属于其经典MC-306封装系列。作为时钟电路的核心频率源器件,该产品专为低功耗、高精度定时场景设计,适配消费电子、工业控制等多领域的定时需求,是RTC(实时时钟)系统的主流配套器件。

二、核心电气参数及实际意义

该晶振的关键参数直接决定了其应用场景和性能表现,具体解析如下:

2.1 标称频率:32.768kHz

32.768kHz是石英晶振的时钟专用频率,核心逻辑在于:32768 = 2¹⁵,经过15级二分频可直接得到1Hz的秒信号——这是时钟电路的核心需求。该频率无需复杂分频电路,能最大程度简化系统设计,同时降低功耗,是几乎所有带计时功能设备的首选频率。

2.2 常温频差:±20ppm

频差是晶振实际频率与标称值的偏差比例,±20ppm的含义是:在25℃(常温)下,实际频率偏差范围为
32.768kHz × 20 × 10⁻⁶ = ±0.65536Hz
该精度可满足绝大多数民用、工业定时场景(如智能手表的时间同步、工业PLC的定时任务),无需额外温补电路即可实现稳定计时,兼顾性能与成本。

2.3 负载电容:7pF

无源晶振需外接匹配电容才能稳定振荡,负载电容是晶振两端到地的总电容(含PCB分布电容)。该晶振要求总负载电容为7pF,设计时通常在晶振两脚各并联一个电容(如12pF,需扣除PCB分布电容1-2pF),确保振荡频率精准锁定在32.768kHz。

三、MC-306封装特性

MC-306是爱普生推出的小型表面贴装(SMD)封装,物理尺寸约为3.2mm×2.5mm×0.8mm(长×宽×高),具有以下核心优势:

  1. 高密度适配:小尺寸适合智能手机、智能手环等小型化设备的PCB布局,节省空间;
  2. 自动化贴装:符合标准SMD封装规范,可通过SMT流水线批量贴装,提高生产效率;
  3. 环保无铅:采用RoHS认证的无铅工艺,满足全球电子行业的环保要求,适配出口产品需求。

四、典型应用场景

Q13MC30610004的特性使其成为以下场景的首选频率源:

  1. 实时时钟(RTC)模块:搭配DS3231、PCF8563等RTC芯片,用于智能手表、智能家居网关、工业控制器的时间存储与同步;
  2. 低功耗消费电子:智能手环、蓝牙耳机、电子秤等设备的计时电路,因无源晶振无需电源,可实现极低碳耗(仅需振荡电路提供激励);
  3. 工业定时系统:PLC、传感器节点的定时采样、任务调度,±20ppm精度可满足工业级定时需求(如每小时偏差不超过2.36秒);
  4. 物联网(IoT)设备:智能电表、环境监测节点的时间戳功能,支持远程数据同步,避免因时间偏差导致的数据混乱。

五、产品优势与可靠性

  1. 品牌可靠性:爱普生作为全球石英晶振龙头,其产品经过多年市场验证,批量一致性好,故障率低,适配大规模量产需求;
  2. 无源特性优势:无需外接电源,仅需振荡电路提供激励,功耗远低于有源晶振,适合电池供电设备(如智能手表的待机计时);
  3. 宽温稳定性:石英晶体的物理特性使其在-40℃至+85℃的常规宽温范围内仍能保持频率稳定,避免环境温度对计时的显著影响;
  4. 成本可控:无源晶振无需内置振荡电路,性价比高于有源晶振,适合对成本敏感的消费电子和工业应用。

总结:Q13MC30610004是一款专为定时场景设计的高性价比无源晶振,以32.768kHz核心频率、±20ppm精度和小型化封装,成为消费电子、工业控制等领域的主流选择,可有效满足各类设备的计时与频率同步需求。

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
