TXM32M0004252DBCEO00T 产品概述

一、产品简介

TXM32M0004252DBCEO00T(品牌:YJX 雅晶鑫)为国产贴片晶振,额定频率 32.000 MHz,封装为 SMD2520-4P(紧凑型表贴封装,典型尺寸约 2.5 × 2.0 mm)。面向工业级和消费电子类应用,工作温度范围 -40 ℃ 至 +85 ℃,适合在苛刻温度环境下使用。

二、主要技术参数

  • 晶振类型:贴片晶振(SMD2520-4P)
  • 频率:32.000 MHz
  • 常温频差:±10 ppm(室温)
  • 频率稳定度(典型,含温度影响):±30 ppm
  • 负载电容:10 pF
  • 等效串联电阻(ESR):35 Ω
  • 工作温度:-40 ℃ ~ +85 ℃
  • 产地:全国产

三、产品特点与优势

  • 小体积、轻重量,便于高密度 PCB 布局。
  • 常温频差优良(±10 ppm),适合对初始频率精度有较高要求的系统。
  • 宽温区频率稳定度(±30 ppm)保证工业级温度下的可靠性。
  • ESR 35 Ω 对常见 MCU/振荡器电路兼容性良好,启动性能稳定。
  • 全国产质量控制,供货和技术支持更便捷。

四、典型应用场景

  • 微控制器主时钟(ARM、MCU 等)
  • 通信设备参考时钟(射频前端、基带处理)
  • 数据采集、工业控制、消费电子设备时钟源
  • 嵌入式系统、物联网终端与便携设备

五、设计与使用建议

  • 负载电容匹配:晶体标称 CL = 10 pF。使用两端对地对称电容 C1、C2 时,满足 CL ≈ (C1·C2)/(C1+C2) + Cstray。常见做法取 C1 = C2 ≈ 2×(CL − Cstray)。例如若 PCB 寄生电容 Cstray 约 2 pF,则可选 C1 = C2 ≈ 16 pF。
  • 布局布线:晶体与 MCU 振荡器引脚间走线要尽量短且对称,避开噪声源(晶振附近禁止大电流回路或高速信号线)。在晶振与两端电容之间尽量少用过孔。
  • 振荡器驱动与 ESR:ESR 越高启动越慢,选型时确认目标 MCU/振荡器能驱动 35 Ω 以下的晶体;必要时调整外部电容或选择驱动能力更强的电路。
  • 去耦与接地:MCU 供电做良好去耦,晶振地与数字地分区但短距离连接,避免地环路。

六、焊接与储存注意

  • 建议遵循行业通用回流焊工艺,参考厂家具体回流曲线;峰值温度通常不超过 260 ℃,并控制时间曲线以避免热应力。
  • 存储与装配遵循防潮、抗静电措施;长时间存储建议密封干燥条件下保存,必要时按厂家建议进行回烘。
  • 裸片搬运与上料注意轻拿轻放,避免机械应力作用在晶体体壳上。

七、选型建议

当系统需要 32 MHz 稳定时钟、占板空间受限且工作温度需覆盖 -40~+85 ℃ 时,TXM32M0004252DBCEO00T 是性价比较高的选择。选型前请核对目标振荡器对 ESR、负载电容及启动时间的要求,并在样机上做实际验证。

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
