XC21M4-32.000-F10NJDTL 贴片晶振产品概述

一、产品基本定位与品牌背景

XC21M4-32.000-F10NJDTL是杭晶电子(HCI) 推出的一款工业级高频贴片石英晶振,核心定位为中高精度时钟源,适配对频率稳定性、宽温适应性有要求的电子系统。HCI作为国内石英晶体器件领域的主流厂商,产品覆盖消费电子、工业控制、通信等多场景,以可靠性、成本优势在市场中广泛应用。

二、核心参数与性能指标

该晶振的关键参数直接决定其适用场景,具体如下:

  • 频率精度:标称频率32.000MHz(精确到小数点后三位,满足大多数系统时钟的基础精度需求);常温(25℃)频差±10ppm,意味着常温下频率偏差不超过320Hz,可覆盖对时钟精度要求较高的应用(如蓝牙4.0模块、低功耗MCU时钟)。
  • 负载电容:10pF(需电路端匹配10pF负载电容以保证谐振稳定,通常采用两个5pF陶瓷电容并联于晶振两端)。
  • 频率稳定度:±30ppm(全工作温度范围内的频率变化范围,结合-40℃~+85℃的宽温,可满足户外、工业现场等温差较大的场景)。
  • 等效串联电阻(ESR):80Ω(ESR是晶振谐振效率的核心指标,80Ω属于工业级常规水平,配合合理振荡电路可保证稳定起振,无“不起振”或“停振”风险)。

三、封装与物理特性

采用SMD2016-4P 四脚贴片封装,物理尺寸为2.0mm×1.6mm×0.8mm(长×宽×高),属于小型化贴片封装:

  • 四脚设计:通常为“两信号输出+两接地”(部分型号为差分输出,但32MHz主流为单端),焊接兼容性强,适配SMT自动化生产线。
  • 无引脚突出:相比插件晶振,贴片封装抗机械应力能力更强,适合振动环境下的设备(如手持终端、车载附件)。
  • 表面处理:引脚采用镀锡工艺,回流焊兼容性好,避免虚焊问题。

四、适用环境与可靠性

  • 工作温度范围:-40℃+85℃(工业级宽温,可覆盖户外设备、工厂车间、低温仓储等场景);存储温度为-55℃+125℃,满足长期库存需求。
  • 抗环境干扰:抗振动能力(10g20g,102000Hz)、抗冲击能力(1000g,0.1ms半正弦波),符合工业设备的环境可靠性要求。
  • 寿命与老化:常规工作寿命≥10年,老化率≤±5ppm/年(第一年),长期使用频率稳定性可靠。

五、典型应用场景

该晶振因尺寸小、宽温稳定、精度适中,广泛应用于以下领域:

  1. 消费电子:智能手表、蓝牙耳机、便携式医疗设备(如血糖仪)的系统时钟;
  2. 工业控制:PLC模块、传感器节点、工业物联网网关的频率参考;
  3. 通信设备:WiFi6模块、蓝牙5.0模块、小型基站(微基站)的时钟源;
  4. 车载附件:车载蓝牙适配器、胎压监测模块(TPMS)的辅助时钟(需确认具体车规要求,若仅需工业级则适配)。

六、选型与使用注意事项

  1. 负载电容匹配:电路端需严格匹配10pF负载电容(晶振两端并联电容总和为10pF),若负载电容偏差超过±2pF,可能导致频率偏移或不起振;
  2. 振荡电路设计:需配合反相器(如74HCU04)+反馈电阻(1MΩ~10MΩ),保证起振裕量(起振条件:振荡电路增益≥ESR×负载电容×2πf);
  3. 焊接工艺:回流焊峰值温度≤260℃,时间≤10秒(避免高温损坏晶振内部石英晶片);
  4. 温度场景适配:若应用温度超过85℃或低于-40℃,需换用宽温/车规级晶振(如HCI的汽车级产品)。

综上,XC21M4-32.000-F10NJDTL是一款性价比突出的工业级贴片晶振,在紧凑电路设计、宽温稳定需求的场景中具有较强竞争力。

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
