1532H4-32K768JWPDTSNL 杭晶低功耗高精度晶振产品概述

一、产品定位与核心价值

1532H4-32K768JWPDTSNL是杭晶(HCI)针对工业级计时/同步场景推出的32.768kHz高精度晶振,核心解决“宽温适应性、低功耗、小尺寸”三大痛点:

  • 兼容1.8V~3.3V主流MCU/SoC,覆盖电池供电与工业电源系统;
  • -40℃~+85℃全温范围稳定工作,适配车间、车载等极端环境;
  • 3.2×2.5mm SMD3225封装,满足高密度PCB布局需求;
  • HCMOS输出无需电平转换,直接匹配数字逻辑电路,降低系统成本。

二、关键技术参数深度解析

1. 频率特性

  • 基础频率:32.768kHz(RTC领域标准频率,与实时时钟模块天然同步);
  • 常温频差:±10ppm(25℃环境下,每月时间误差≤2秒,满足普通计时精度);
  • 全温稳定度:±30ppm(-40℃~+85℃范围内,时间误差≤6秒/月,适配工业级温度波动)。

2. 电气参数

  • 工作电压:1.8V~3.3V(覆盖低功耗MCU<如STM32L系列>到3.3V工业系统);
  • 工作电流:10mA(注:若为低功耗设计,实际典型值为10μA级别,需以官方 datasheet 为准);
  • 输出模式:HCMOS(高电平≈VDD,低电平≈GND,输出摆幅大,抗干扰能力强)。

3. 环境参数

  • 工作温度:-40℃~+85℃(工业级标准,满足车载、户外监测等场景);
  • 存储温度:-55℃~+125℃(长期存储稳定性可靠)。

三、封装形式与引脚定义

采用SMD3225-4P贴片封装,尺寸为3.2mm×2.5mm×0.8mm(典型高度),4引脚常规定义如下(需以杭晶官方 datasheet 确认):

引脚编号 功能 说明 1 VDD 电源正极 2 GND 电源地 3 OUT 32.768kHz输出端 4 NC 无连接(悬空或接地均可)

焊接注意:引脚间距0.5mm,需避免桥接;回流焊峰值温度≤260℃,焊接时间≤10秒。

四、典型应用场景

  1. 工业控制与自动化:PLC(可编程逻辑控制器)RTC模块、工业传感器时间戳同步,利用宽温特性适应车间高低温环境;
  2. 物联网(IoT)设备:智能门锁、环境监测节点的低功耗计时,1.8V~3.3V电压兼容电池供电的低功耗MCU;
  3. 车载电子:车载导航、仪表盘时间同步,满足车载-40℃~85℃温度要求,抗振动性能可靠;
  4. 消费电子:智能手表、手环的计时核心,小尺寸封装适配可穿戴设备紧凑空间,低功耗延长电池续航。

五、可靠性与环境适应性

杭晶作为国内晶振领域知名品牌,1532H4-32K768JWPDTSNL具备以下可靠性优势:

  • 抗干扰:HCMOS输出及内部屏蔽设计,减少电磁干扰(EMI);
  • 长期稳定性:老化率≤±5ppm/年(典型值),确保10年以上时间精度可靠;
  • 环保认证:符合RoHS 2.0及REACH标准,无铅无镉,满足出口要求;
  • 抗振动:可承受10g/20~2000Hz振动(典型值),适配车载、工业机械等振动场景。

六、使用注意事项

  1. 电源滤波:在VDD(引脚1)与GND(引脚2)之间并联0.1μF陶瓷电容,抑制电源噪声;
  2. 静电防护:晶振为静电敏感元件,操作时需佩戴防静电手环,使用防静电工作台;
  3. 布局设计:远离WiFi、蓝牙等高频模块,输出端尽量靠近MCU的XTAL1/XTAL2引脚,缩短走线长度;
  4. 存储条件:常温干燥环境存储,避免阳光直射及潮湿,存储周期≤12个月。

该产品凭借高性价比与工业级可靠性,成为物联网、工业控制、车载电子等领域的优选计时晶振。具体参数需以杭晶官方最新 datasheet 为准。

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
