FR07S4-32.768-N07LLDT 贴片晶振产品概述

一、产品定位与品牌背景

FR07S4-32.768-N07LLDT是杭晶电子(HCI) 推出的工业级高精度贴片晶振,核心频率为32.768kHz(实时时钟RTC领域的标准基准频率),专为低功耗、宽温环境下的时间同步与时钟基准需求设计。杭晶电子作为国内晶振行业主流厂商,拥有10余年石英晶体器件研发制造经验,产品覆盖消费电子、工业控制、车载等多领域,以高可靠性、成本优势著称,是替代进口同规格晶振的高性价比选择。

二、核心性能参数深度解析

该晶振的关键参数直接决定适用场景与性能表现,具体解析如下:

  1. 频率精度(常温频差):±20ppm,换算为实际频率偏差为±0.65536Hz(32.768kHz×20×10⁻⁶),满足绝大多数RTC模块的时间精度要求(如每日误差不超过1.5秒,远低于常规应用的可接受范围)。
  2. 负载电容:7pF,与主流RTC芯片(如NXP PCF8563、Maxim DS3231、TI CC2640内置RTC)的典型负载电容匹配,无需额外匹配电容,简化电路设计。
  3. 等效串联电阻(ESR):50kΩ,低ESR设计可降低振荡电路功耗(典型工作电流<1μA),提升启动速度(一般小于1ms),同时增强宽温下的振荡稳定性,避免停振风险。
  4. 频率稳定度:±20ppm(覆盖工作温度范围),即从-40℃到+85℃的全温区内,频率偏差不超过±20ppm,满足工业级、车载等宽温场景的可靠性要求。
  5. 频率特性:32.768kHz为国际通用RTC基准频率,与全球多数电子设备的时钟协议兼容,无需频率转换即可实现时间同步。

三、封装设计与物理特性

该晶振采用MC-146紧凑贴片封装,具体物理参数如下:

  • 尺寸:2.0mm×1.6mm×0.7mm(长×宽×高),属于小型化贴片封装,适合便携式、小型化电子设备(如智能手环、蓝牙耳机)。
  • 引脚布局:2引脚贴片式,符合标准SMD焊接工艺,兼容回流焊、波峰焊等常规生产流程,无铅环保(符合RoHS 2.0标准)。
  • 封装材料:陶瓷封装,具备优异的防潮、抗振动性能,可承受10g20g的振动(102000Hz)与1000g的冲击(半正弦波,0.1ms),适合移动设备或工业现场环境。

四、关键性能优势

  1. 宽温稳定可靠:工作温度范围-40℃~+85℃,频率稳定度±20ppm,可在严寒(如北方户外监控)、高温(如车载仪表盘)环境下持续稳定工作。
  2. 低功耗适配:32.768kHz晶振本身功耗极低,搭配50kΩ低ESR,适合电池供电的IoT节点、智能穿戴设备,延长续航时间(单次充电可支持1年以上时间同步)。
  3. 高兼容性:负载电容7pF匹配90%以上主流RTC芯片,无需额外电路调整,降低设计成本与研发周期。
  4. 抗干扰能力强:陶瓷封装与稳定的频率特性,可有效抵抗电磁干扰(EMI),避免外部信号对时钟精度的影响(如工业现场的电机干扰)。

五、典型应用场景

该晶振的性能特点使其广泛适用于以下领域:

  1. 智能穿戴:智能手表、手环的RTC模块,实现精准时间显示与睡眠监测的时间同步。
  2. 物联网节点:低功耗传感器、智能门锁的时间戳功能,确保数据采集的时间一致性。
  3. 工业控制:PLC、工业传感器的时钟基准,保证生产线的时序控制精度(如自动化装配线的节拍同步)。
  4. 车载电子:车载导航、仪表盘的时间校准,支持车辆定位与行驶数据的时间同步。
  5. 消费电子:智能电视、路由器的RTC模块,实现断电后的时间记忆与网络同步。

六、总结

FR07S4-32.768-N07LLDT作为杭晶电子的工业级贴片晶振,以高精度、宽温稳定、低功耗、高兼容性为核心优势,覆盖消费电子、工业、车载等多场景需求。其紧凑的MC-146封装与成熟工艺,可直接替代同规格进口晶振,是小型化电子设备时钟基准的高性价比选择。

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
