FC21M2-32.768-N07LLDT 贴片晶振产品概述

一、产品核心定位与适用场景

FC21M2-32.768-N07LLDT是杭晶(HCI)推出的低功耗高稳定32.768kHz贴片晶振,专为对时钟精度、环境适应性及小型化设计有需求的电子设备打造。32.768kHz作为实时时钟(RTC)领域的标准频率(2¹⁵ Hz),可通过简单分频实现秒、分、时等计时单位,是各类计时电路的核心元件。本产品聚焦RTC、低速同步及低功耗计时场景,兼顾性能与成本,适配消费电子、工业控制、物联网等多领域应用。

二、关键参数与性能优势

本产品的核心参数围绕“稳定、低耗、适配性”设计,具体优势如下:

  1. 高精度频率控制:常温频差±20ppm,换算成年计时误差约**±10.5分钟**(20ppm×365天×24小时×3600秒/小时≈630秒),满足多数消费电子与工业计时的精度需求;
  2. 宽温频率稳定:频率稳定度±20ppm(-40℃~+85℃),温度变化时频率偏移控制在极小范围,避免极端环境下计时偏差过大;
  3. 低ESR起振可靠:等效串联电阻(ESR)≤50kΩ,属于同频率贴片晶振的低ESR水平,可降低起振驱动功率,提升电路抗干扰能力,减少起振失败风险;
  4. 适配性负载电容:负载电容7pF,与多数MCU(如STM32系列)、RTC芯片(如DS3231)的内部负载设计匹配,无需额外添加外部电容,简化电路并降低BOM成本。

三、封装与可靠性设计

  1. 小型化贴片封装:采用SMD2012-2P封装,尺寸仅2.0mm×1.2mm×0.7mm(典型值),无引脚设计适配高密度PCB布局,满足智能穿戴、微型传感器等设备的空间需求;
  2. 抗环境干扰设计:真空密封封装工艺防止水汽、灰尘侵入,提升长期频率稳定性;SMD封装抗振动(10g~2000Hz)、抗冲击(1000g/0.1ms)性能优异,适合移动设备与工业振动场景;
  3. 环保合规:符合RoHS 2.0、REACH等标准,无铅无卤,适配全球市场需求。

四、品牌与品质保障

杭晶(HCI)是国内晶振行业主流制造商,拥有20余年晶体器件研发生产经验,产品覆盖石英晶振、陶瓷晶振等全系列。FC21M2-32.768-N07LLDT出厂前需经过多轮严格测试:包括常温/温循频率校准、ESR测试、振动冲击测试、24小时以上老化测试,确保每批次产品一致性与可靠性,可提供完整测试报告与认证文件。

五、典型应用领域

  1. 实时时钟(RTC)模块:独立RTC芯片(如DS3231)、MCU内置RTC(如STM32L系列)的计时基准;
  2. 智能穿戴设备:智能手表、手环、健康监测设备的低功耗计时与睡眠监测时钟;
  3. 物联网(IoT)节点:低功耗传感器(温湿度、运动传感器)的定时采样与数据同步;
  4. 消费电子:智能家居设备(智能门锁、温湿度控制器)、小型家电(智能闹钟、加湿器)的定时功能;
  5. 工业控制:PLC、远程IO模块、工业传感器的低功耗计时与状态同步。

FC21M2-32.768-N07LLDT凭借稳定性能、小型化封装与高可靠性,成为RTC及低速计时场景的高性价比选择,适配多领域设备设计需求。

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
