TAXM3.579M2ILFBET2T 无源贴片晶振产品概述

TAXM3.579M2ILFBET2T是雅晶鑫(YJX)推出的一款无源贴片晶振,采用HC-49S-SMD封装,针对消费电子、小型工业控制等场景设计,以平衡的频率精度、可靠性能与成本优势,成为诸多电子设备时钟/振荡电路的常用选择。

一、产品基本定位

该晶振属于雅晶鑫无源晶振系列中的常规规格,核心是提供稳定的3.579545MHz基准频率——这一频率因历史应用积累(如早期电视信号处理、遥控器时钟)而具备广泛兼容性,无需额外频率转换即可匹配多数成熟电路方案。作为无源器件,它无内置振荡电路,需外接匹配电容、电阻等组成振荡回路,适合对成本敏感、电路设计灵活的场景。

二、核心技术参数解析

(一)频率特性

  • 标称频率:3.579545MHz,电子行业经典频率之一,适配大量消费电子、通信辅助电路的时钟需求;
  • 常温频差:±30ppm,即频率偏差范围为±10.8Hz(计算:3.579545MHz×30×10^-6),满足一般设备对频率精度的基本要求;
  • 频率稳定度:±30ppm,指工作温度、电源波动等条件下的频率波动范围,与常温频差一致,确保常规环境下的频率稳定性。

(二)电性能与负载

  • 等效串联电阻(ESR):150Ω,是影响晶振起振可靠性的关键参数,处于无源晶振合理区间,可降低振荡回路设计难度;
  • 负载电容:20pF,无源晶振需外接22pF左右匹配电容(行业通用值),无需特殊电路设计即可适配。

(三)环境适应性

  • 工作温度:-20℃~+70℃,覆盖室内常温及北方室内等低温场景,不适用于极端高低温环境;
  • 存储温度:常规无源晶振存储范围为-40℃~+85℃(雅晶鑫标准),满足一般仓储要求。

三、封装与品牌背景

(一)封装设计

采用HC-49S-SMD贴片封装:

  • HC-49S是晶振行业经典封装(兼顾体积与可靠性),贴片式支持自动化SMT贴装,提高生产效率、降低人工成本;
  • 封装尺寸符合行业标准,可直接替换同规格竞品,兼容性强。

(二)品牌支持

雅晶鑫(YJX)是国内专注晶振研发生产的厂商,产品覆盖无源/有源晶振、温补晶振等,在消费电子、小型工业领域具备成熟供应链与技术支持,TAXM3.579M2ILFBET2T延续了品牌对常规规格的稳定供应能力。

四、典型应用场景

该晶振因频率经典、参数适配,广泛应用于:

  1. 消费电子:电视遥控器、小型家电(电风扇、加湿器)控制板、智能音箱辅助时钟;
  2. 通信辅助:433MHz无线遥控器时钟基准、小型路由器指示灯控制电路;
  3. 工业控制:温湿度传感器节点、简易PLC辅助时钟;
  4. 传统电子:早期数字电视信号处理模块、老式DVD播放机时钟(存量设备仍在使用)。

五、性能优势与适用限制

(一)核心优势

  • 成本可控:无源设计无内置电路,单价低于有源晶振,适合批量应用;
  • 兼容性强:经典频率+通用负载电容,电路匹配简单,可快速集成;
  • 生产适配:贴片封装支持SMT,符合现代电子制造流程;
  • 可靠性稳定:ESR控制在150Ω,振荡回路起振概率高,降低设备故障风险。

(二)适用限制

  • 不支持宽温环境(-40℃~+85℃以上),不适用于户外、车载等极端温度场景;
  • 无源设计需外接振荡回路,不适合体积极致紧凑的场景(有源晶振更适配);
  • 频差±30ppm仅满足常规需求,高精度场景(通信基站、医疗设备)需选用温补/恒温晶振。

综上,TAXM3.579M2ILFBET2T是一款高性价比的常规无源贴片晶振,以经典频率、通用参数适配多数消费电子与小型工业场景,是成本敏感型设备时钟电路的可靠选择。

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
