HCI 3131M-32.768DT07NNL 贴片晶振产品概述

一、产品定位与核心应用

HCI 3131M-32.768DT07NNL是杭晶电子(HCI)推出的工业级SMD3215封装贴片晶振,核心频率为32.768kHz(实时时钟RTC领域的标准基准频率),针对低功耗、宽温环境下的时钟同步需求设计,广泛应用于消费电子、工业控制、物联网及小型嵌入式系统等场景。

二、关键性能参数详解

1. 频率特性:精准稳定的时钟基准

  • 核心频率:32.768kHz,与RTC模块、单片机时钟系统的分频设计完全匹配,无需额外复杂分频电路;
  • 常温频差:±10ppm,即常温下(25℃)频率偏差控制在0.32768Hz以内,满足大多数电子设备的时间精度要求(如智能手环每日误差≤8.64秒);
  • 频率稳定度:±10ppm,覆盖-40℃~+85℃工作温度范围,高低温下频率漂移极小,避免因温度变化导致时钟误差(如-40℃时每日误差≤8.64秒)。

2. 负载电容与ESR:优化电路匹配与稳定性

  • 负载电容:7pF,设计振荡电路时需匹配7pF左右的负载电容,可简化电路调试流程,提高批量生产的一致性;
  • 等效串联电阻(ESR):70Ω,在SMD3215封装同类产品中属于较低水平,低ESR可降低振荡电路功耗(约降低20%~30%),同时提升电路抗干扰能力,避免因ESR过高导致振荡停止。

3. 工作温度与可靠性:适应工业级环境

  • 工作温度范围:-40℃~+85℃,覆盖户外传感器、车载(非车规级扩展)、工业控制器等场景的温度需求;
  • 存储温度:-55℃~+125℃(杭晶同系列标准),满足运输、存储过程中的环境变化要求。

三、封装与工艺设计

1. SMD3215封装:小型化与兼容性

  • 尺寸:3.2mm×1.5mm×0.8mm,体积紧凑,适配智能手环、小型传感器等高密度集成设备;
  • 封装类型:陶瓷贴片封装,符合IPC-A-610电子组装标准,兼容回流焊、波峰焊工艺,焊接可靠性高(焊点剪切强度≥15N)。

2. 杭晶特有的可靠性设计

  • 气密性封装:采用激光焊接陶瓷外壳,气密性≤1×10^-8 Pa·cm³/s(氦检漏标准),防止水汽、灰尘侵入影响石英晶体性能;
  • 抗机械冲击:符合GB/T 2423.10标准,可承受10g(10~2000Hz)的随机振动,适应运输、安装过程中的机械应力。

四、典型应用场景与核心优势

1. 典型应用场景

  • 可穿戴设备:智能手环、手表的RTC模块,保障时间同步与低功耗待机(待机电流可低至1μA);
  • 工业物联网节点:户外温湿度传感器、无线LoRa模块的时钟基准,宽温特性适配极端环境(如北方冬季户外部署);
  • 消费电子:智能电视、路由器、智能家居设备的实时时钟,提升设备开机时间准确性(避免每次开机时间重置);
  • 小型工业控制器:PLC扩展模块、单片机系统的时钟单元,满足工业现场的宽温需求(如车间高温环境)。

2. 核心优势总结

  • 性能均衡:频差、稳定度、ESR参数匹配主流需求,无需额外选型优化;
  • 宽温可靠:-40℃~+85℃覆盖工业场景,高低温下性能稳定;
  • 小型化适配:SMD3215封装适合紧凑设计,满足小型化设备需求;
  • 品牌保障:杭晶电子(HCI)是国内晶振行业龙头,产品经过多年市场验证,可靠性有保障。

该产品通过了RoHS、REACH等环保认证,符合全球电子设备的环保要求,是低功耗时钟系统的高性价比选型。

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
