HCI 0111M4-24.000F12DTNLL 贴片晶振产品概述

一、核心基础参数

该晶振为杭晶(HCI)推出的24MHz高频工业级贴片晶振,关键参数覆盖电子设备时钟系统的核心需求:

  • 频率精度:常温(25℃)频差±10ppm,对应24MHz下最大偏差为240Hz,满足多数中精度场景(如通信同步、计时)的误差要求;
  • 负载电容:12pF(典型值),是振荡电路匹配的核心指标,需外围并联对应电容实现稳定谐振;
  • 等效串联电阻(ESR):150Ω(最大值),直接影响振荡幅度与稳定性,处于主流MCU/模块的驱动能力范围内;
  • 频率稳定度:±20ppm(-40℃~+85℃范围),涵盖温度变化带来的频率漂移,确保宽温环境下性能一致性;
  • 温度范围:-40℃~+85℃,符合工业级温度标准,可适应户外、车载等严苛场景。

二、封装与物理特性

采用SMD1612-4P封装,尺寸为1.6mm×1.2mm×0.5mm(典型值),4引脚贴片式设计:

  • 封装紧凑,适配小型化设备(如穿戴、IoT模块)的空间限制;
  • 引脚布局符合行业标准,兼容多数PCB设计规范,焊接工艺成熟(回流焊、波峰焊均可适配);
  • 表面贴装方式无需插件,提高生产效率,降低设备体积与重量。

三、电气性能与可靠性特点

  1. 振荡稳定性:12pF负载电容匹配下,结合±10ppm常温频差,可实现稳定时钟输出,避免通信丢包、计时误差;
  2. 驱动兼容性:150Ω ESR适配主流MCU(STM32、ATmega系列)、蓝牙/WiFi模块(ESP8266、nRF52)的振荡电路,无需额外驱动放大;
  3. 宽温可靠性:-40℃~+85℃工作范围配合±20ppm频率稳定度,满足户外设备、车载电子的环境要求,避免温度波动导致性能失效;
  4. 低功耗特性:贴片封装优化寄生参数,结合合理ESR,降低振荡电路功耗,适合电池供电设备(如智能手环)。

四、典型应用场景

该晶振因24MHz常用频率、工业级温度范围及紧凑封装,广泛应用于:

  • IoT与通信模块:蓝牙BLE(CC2541)、WiFi模块(ESP32部分型号)的参考时钟,确保无线通信频率同步;
  • 单片机系统:STM32F1/F4系列、ATmega328P的外部晶振,作为系统时钟倍频基础(如24MHz倍频至72MHz/96MHz);
  • 工业控制:PLC辅助时钟、传感器节点定时模块,适应车间-40℃~+85℃的温度变化;
  • 穿戴设备:智能手环、手表的计时与通信模块,兼顾小体积与宽温可靠性;
  • 车载电子:车载蓝牙、导航设备的时钟源,满足车载环境的温度与振动要求(需额外验证振动指标)。

五、选型与应用注意事项

  1. 负载电容匹配:外围需并联两个12pFNP0/C0G材质陶瓷电容(温度系数稳定),避免X7R/X5R材质(温度系数大,影响频率精度);
  2. 焊接工艺:回流焊温度曲线需符合HCI推荐(峰值240℃~260℃,时间≤10s),避免过热导致晶振老化;
  3. 静电防护:晶振对静电敏感(小封装尤甚),生产需佩戴静电手环,存储于防静电包装;
  4. 驱动验证:低功耗MCU(如MSP430)需确认晶振驱动引脚最大负载能力(≥200Ω即可满足150Ω ESR)。

六、总结

HCI 0111M4-24.000F12DTNLL是一款工业级24MHz贴片晶振,兼顾紧凑封装、宽温可靠性与主流设备兼容性,适合IoT、工业控制、穿戴等场景的时钟需求。其核心参数匹配多数中精度电子设备的设计要求,是小型化、宽温应用的高性价比选择。

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
