FC31M2-32.768-N09LLDT 贴片晶振产品概述

FC31M2-32.768-N09LLDT是杭晶电子(HCI)推出的一款工业级高精度32.768kHz贴片晶振,专为低功耗、稳定时钟基准需求设计,广泛适配消费电子、工业控制、物联网等多领域应用。

一、产品定位与核心应用场景

该晶振属于实时时钟(RTC)专用基准器件,聚焦“低功耗+高稳定”核心需求,主要应用场景包括:

  1. 消费电子:智能手环、手表的RTC模块(实现时间同步与低功耗待机)、蓝牙耳机的时钟基准;
  2. 工业控制:PLC(可编程逻辑控制器)的实时时钟单元、工业传感器节点的时间戳记录;
  3. 物联网设备:低功耗广域网(LoRa、NB-IoT)终端的时间同步、智能电表的计时模块;
  4. 车载辅助:车载中控的备用时钟(非车规级但适配部分商用车环境)。

二、核心参数详细解析

FC31M2-32.768-N09LLDT的参数设计精准匹配RTC场景需求,关键指标如下:

  1. 频率与频差:
    • 标称频率:32.768kHz(RTC领域标准频率,与数字分频电路完美适配,可直接生成1Hz秒脉冲);
    • 常温频差:±20ppm(换算为时间误差约±1.728秒/天,满足绝大多数日常计时需求);
  2. 负载电容:9pF(振荡电路需匹配该电容以保证起振稳定,电路设计时需在晶振两端并联18pF左右电容,因晶振本身含约1pF寄生电容);
  3. 等效串联电阻(ESR):50kΩ(串联电阻直接影响起振能力,50kΩ属于常规低阻范围,适配1.8~3.3V工作电压的振荡电路);
  4. 频率稳定度:±20ppm(覆盖全工作温度范围-40℃~+85℃,可有效抑制温度变化、电压波动带来的频率漂移);
  5. 工作温度范围:-40℃~+85℃(工业级宽温设计,可适应户外、车间等温差较大的环境)。

三、封装与电气特性

  1. 封装形式:SMD3215-2P(贴片式3.2×1.5×0.8mm超小封装),兼容自动化贴装工艺,可节省PCB布局空间,适合高密度集成设计;
  2. 电气特性补充:
    • 工作电压:常规适配1.8~3.3V(低功耗设计,典型功耗<1μW);
    • 起振时间:≤10ms(快速起振,满足设备开机后快速建立稳定时钟的需求);
    • 焊接兼容性:支持回流焊(260℃±5℃,持续时间≤10秒)、波峰焊等常规贴片焊接工艺。

四、可靠性与环境适应性

FC31M2-32.768-N09LLDT通过多项可靠性测试,确保在复杂场景下稳定工作:

  1. 环境适应性:
    • 温度循环:-40℃~+85℃,循环次数≥500次(无频率漂移超标);
    • 湿度:95%RH(40℃),持续96小时(无性能衰减);
  2. 机械可靠性:
    • 振动:10~2000Hz,加速度1.5g(符合IEC 60068-2-6标准);
    • 冲击:1000g,持续0.5ms(符合IEC 60068-2-27标准);
  3. 环保合规:符合RoHS 2.0、REACH等环保指令,无铅焊接兼容。

五、品牌与品质保障

杭晶电子(HCI)作为国内晶振行业骨干企业,拥有15+年生产经验,FC31M2系列产品具备:

  1. 质量体系认证:通过ISO 9001质量管理体系、ISO 14001环境管理体系认证;
  2. 供货稳定性:月产能≥1000万只,可满足批量采购需求;
  3. 售后支持:提供技术咨询、样品测试等服务,部分批次支持定制化参数调整。

该产品凭借“小封装、低功耗、宽温稳定”的核心优势,成为RTC场景下的高性价比选择,可有效降低设备设计复杂度与成本。

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
