XC21M4-25.000-F12NLDTL 贴片晶振产品概述

XC21M4-25.000-F12NLDTL是杭晶电子(HCI)推出的一款工业级小型化贴片石英晶体谐振器,针对中高频率精度与宽温环境需求设计,具备紧凑封装、稳定性能等特点,广泛适配消费电子、通信、工业控制等领域的设备应用。

一、产品基本属性定位

该产品属于通用型石英晶体谐振器,采用SMD2016-4P封装(尺寸2.0×1.6mm),标称频率25MHz,核心面向需要小型化布局与宽温可靠性的电子设备。作为HCI的主流贴片晶振产品之一,其参数设计平衡了精度、成本与环境适应性,适合多数中端电子设备的振荡电路需求。

二、核心电气性能参数详解

  1. 频率与频差控制
    标称频率为25MHz,常温(25℃)下频差为±10ppm,换算为实际频率偏差为±250Hz(25MHz×10ppm=250Hz)。该精度满足多数通信协议(如Wi-Fi、蓝牙)的频率同步要求,避免因频率偏移导致的信号干扰或通信失败。

  2. 负载电容匹配
    负载电容为12pF,需注意:晶振的谐振频率会随电路负载电容变化而偏移,因此用户在PCB设计时,需在振荡电路的输入/输出端并联总等效负载电容12pF(含晶振引脚寄生电容、PCB布线电容),确保谐振频率准确稳定。

  3. 温度频率稳定度
    工作温度范围为-40℃~+85℃(工业级宽温),对应频率稳定度为±20ppm。这意味着在极端温度环境下(如车载冬季低温、夏季高温),频率偏差仍控制在±500Hz以内,满足严苛环境下的长期稳定工作需求。

  4. 等效串联电阻(ESR)
    ESR为100Ω,属于中低水平。ESR越低,晶振的起振裕量越大,越容易与MCU、FPGA等主控芯片的内部振荡电路匹配,减少因ESR过高导致的不起振或振荡不稳定问题。

  5. 长期老化性能
    石英晶振的长期老化率通常在每年1~5ppm,该产品经HCI老化测试,可保证在使用周期内(如5年)频率偏移不超过±10ppm,满足设备长期可靠运行的要求。

三、封装与焊接适配性

采用SMD2016-4P 4引脚贴片封装,尺寸仅2.0×1.6mm×0.7mm(典型高度),大幅节省PCB空间,适合智能手表、蓝牙耳机等小型化设备的高密度布局。
焊接兼容性方面,支持回流焊(符合JEDEC标准)与波峰焊工艺,引脚间距与焊盘设计适配主流SMT生产线,可实现高效批量生产,降低焊接不良率。

四、环境可靠性验证

该产品通过多项环境可靠性测试,确保在复杂场景下的稳定工作:

  • 温度循环测试:-40℃~+85℃循环1000次后,频率偏差仍在±20ppm以内;
  • 湿度测试:85%RH/85℃环境下持续1000小时,性能无明显衰减;
  • 机械可靠性:抗振动(10~2000Hz,加速度1g)与冲击(1000g,1ms)测试,封装无破损、性能无变化,适合车载、手持移动设备等振动场景。

五、典型应用场景

  1. 消费电子领域:智能手表、蓝牙耳机、便携式蓝牙音箱(小型化封装+宽温适配);
  2. 通信设备:无线路由器、交换机、无线AP(频率精度满足Wi-Fi/蓝牙协议要求);
  3. 工业控制:PLC模块、工业传感器节点、远程监控设备(宽温范围适配工业现场环境);
  4. 车载电子:车载导航、行车记录仪、车机系统(-40℃~+85℃温度范围适配车载高低温场景)。

综上,XC21M4-25.000-F12NLDTL凭借紧凑封装、中高精度、宽温可靠性等特点,成为多领域电子设备振荡电路的优选晶振方案,可有效平衡性能与成本,满足中端设备的长期稳定运行需求。

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
