TAXM20M4RLBCCT2T无源贴片晶振产品概述

一、产品基本定位与核心属性

TAXM20M4RLBCCT2T是雅晶鑫(YJX)推出的无源石英贴片晶振,采用SMD3225-4P封装(3.2×2.5mm),属于通用型频率基准器件。其核心作用是为各类电子设备提供稳定的20MHz时钟信号,适配对尺寸紧凑、温度适应性有要求的中低端应用场景,无需外部电源驱动,电路设计简单且成本可控。

二、关键电气参数详解

该晶振的电气参数直接决定其性能适配性,核心参数及意义如下:

  1. 基准频率:20MHz(当前电子设备常用中频,兼容多数MCU、通信芯片的时钟输入);
  2. 常温频差:±10ppm(20℃环境下,频率偏差范围为20MHz±200Hz,满足一般消费电子、工业控制的精度需求);
  3. 负载电容:20pF(振荡电路关键匹配参数,需配置含寄生电容在内的20pF负载电容以保证稳定振荡);
  4. 全温频率稳定度:±50ppm(-40℃~+85℃范围内,最大频率偏差20MHz±1kHz,覆盖宽温变化场景);
  5. 等效串联电阻(ESR):80Ω(无源晶振中较低水平,降低振荡电路起振难度,提升信号稳定性);
  6. 工作温度范围:-40℃~+85℃(支持户外、工业现场等复杂温度环境)。

三、封装与引脚配置

采用SMD3225-4P封装(4引脚表面贴装),具备以下优势:

  • 小型化:尺寸仅3.2mm×2.5mm×0.8mm(典型高度),适配智能穿戴、蓝牙耳机等小型设备的紧凑布局;
  • 贴装便捷:兼容SMT自动化生产,提升生产效率;
  • 引脚定义:4引脚含2个振荡端、2个接地端(需参考官方 datasheet 确认具体功能),接地端可增强抗干扰性。

四、环境适应性与可靠性

  1. 宽温稳定性:全温度范围频率稳定度±50ppm,在-40℃低温或+85℃高温下,仍能保持时钟信号可靠性,避免设备因温度波动出现性能偏差;
  2. 无源特性:无需外部电源,仅需匹配振荡电路即可工作,电路设计简化且故障率低;
  3. 抗振性:贴片封装结构紧凑,抗机械振动性能优于直插晶振,适合无人机、车载终端等振动敏感场景。

五、典型应用场景

该晶振因尺寸小、宽温适配、精度适中,广泛应用于:

  1. 消费电子:智能手表、蓝牙耳机、便携式音箱(满足小型化与稳定时钟需求);
  2. 工业控制:PLC模块、传感器节点、小型工业仪表(适配-40℃~+85℃工业环境);
  3. 通信设备:家用路由器、小型微基站、无线AP(提供稳定20MHz时钟基准);
  4. 汽车电子:车载信息娱乐系统(车机)、胎压监测模块(TPMS)(符合车载级温度要求)。

六、使用注意事项

  1. 负载电容匹配:电路需配置总负载电容(含晶振寄生电容)接近20pF,偏差过大会导致频率偏移或振荡不稳定;
  2. 布局设计:晶振周围避免强电磁干扰源(如高频电感、功率器件),振荡电路的电容、电阻需靠近晶振引脚,减少寄生参数影响;
  3. 焊接温度:回流焊峰值控制在240℃~260℃(时间≤10s),避免高温损坏石英晶体;
  4. 存储条件:未使用晶振存储于常温干燥环境(0℃~35℃,湿度≤60%),防止受潮影响性能。

该产品以高性价比、宽温适配和小型化优势,成为中低端电子设备时钟基准的常用选择。

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
