TXM16M0004252BBCEO00T 无源贴片晶振产品概述

TXM16M0004252BBCEO00T是雅晶鑫(YJX)品牌推出的一款小型化无源石英晶振,采用SMD2520-4P封装,核心参数覆盖通用16MHz频率及工业级温宽,适用于多数嵌入式系统、工业控制及消费电子场景。

一、产品基本信息

该型号为无源晶振(无内置振荡电路,需外接匹配电路才能工作),品牌为雅晶鑫(YJX),封装类型为SMD2520-4P(尺寸约2.5mm×2.0mm×0.8mm,4引脚贴片封装),型号后缀明确16MHz标称频率及参数配置,支持自动化表面贴装(SMT),可有效节省PCB布局空间。

二、核心性能参数解析

1. 频率与精度

  • 标称频率:16MHz,属于通用时钟频率,广泛适配MCU、通信接口(USB、UART等)及数字电路时钟源;
  • 常温频差:±10ppm,即25℃常温下,实际频率与标称值偏差不超过16MHz×10ppm=160Hz,满足一般工业、消费类产品精度需求;
  • 频率稳定度:±30ppm,指-40℃~+85℃范围内,频率相对于常温的最大偏移为480Hz,确保宽温环境下时钟稳定性。

2. 电气特性

  • 负载电容:8pF,无源晶振需匹配此电容才能达到标称频率,应用时需保证电路等效负载电容(含引脚寄生电容、外围电容)总和接近8pF;
  • 等效串联电阻(ESR):60Ω,属于该封装合理范围,低ESR可降低振荡电路驱动要求,保证可靠起振。

三、封装与典型应用场景

1. 封装特点

SMD2520-4P为小型化贴片设计,支持SMT自动化贴装,适用于对PCB空间要求严格的产品(如智能穿戴、小型传感器模块),引脚布局紧凑,抗机械振动性能较好。

2. 典型应用

结合参数特性,该晶振适用于:

  • 工业控制:PLC模块、传感器节点、电机控制器(宽温适配工业环境);
  • 消费电子:智能手环、小型家电(智能插座、温控器)的MCU时钟;
  • 通信接口:USB2.0、UART、SPI等接口参考时钟;
  • 嵌入式系统:单片机(STM32系列)、FPGA的外部时钟源。

四、环境适应性说明

该晶振工作温度范围为**-40℃+85℃**,覆盖工业级温宽,可适应低温(户外设备、北方冬季)及高温(密闭机箱散热环境)场景;存储温度默认符合无源晶振常规标准(-55℃+125℃),相对湿度可承受5%~95%(非冷凝),满足多数应用环境要求。

五、应用注意事项

1. 负载电容匹配

需在晶振两端并联匹配电容,确保等效负载电容接近8pF。例如:若引脚寄生电容为2pF,则外围电容可选用两个12pF(并联后6pF,加寄生电容共8pF),或一个10pF+一个15pF(并联后6pF),具体需根据实际寄生电容调整。

2. 布局与起振

  • 晶振应靠近MCU时钟引脚,时钟线长度≤10mm,避免电磁干扰;
  • 晶振下方及周边尽量不布线,减少寄生电容影响;
  • 确保振荡电路驱动能力满足ESR≤60Ω要求,避免不起振或振荡不稳定。

3. 焊接工艺

回流焊需遵循常规SMT曲线(峰值温度≤260℃,回流时间≤10s);手工焊接烙铁温度≤350℃,焊接时间≤3s,避免过热损坏晶振。

该型号凭借小型化封装、宽温稳定性及通用频率,可作为多数中低端电子设备的可靠时钟源,满足量产及成本控制需求。

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
