TXM26M0004252FBCEO00T 无源贴片晶振产品概述
一、产品基本信息
TXM26M0004252FBCEO00T是雅晶鑫（YJX）推出的无源贴片石英晶振，属于通用时钟基准器件。作为无源晶振，它需配合外部振荡电路（如MCU内部振荡器、专用振荡芯片）及匹配电容使用，无需内置振荡组件，因此成本更具优势，同时适配自动化表面贴装工艺，是电子设备中常用的高精度时钟解决方案。
二、核心参数详解
1. 频率特性
- 标称频率：26MHz（通信、数字电路领域的通用基准频率，覆盖WiFi、蓝牙、MCU等主流应用）；
- 常温频差：±10ppm（25℃环境下频率偏差控制在10×10⁻⁶以内，满足常规产品对频率精度的要求）；
- 频率稳定度：±30ppm（工作温度范围内，频率相对于常温的最大变化量，可保证系统时钟在温差波动下的稳定性）。
2. 电气特性
- 负载电容：12pF（无源晶振的常用匹配值，用户可直接选择12pF陶瓷电容作为外接元件，简化电路设计）；
- 等效串联电阻（ESR）：40Ω（直接影响振荡起振能力与功耗，40Ω属于中等偏优水平，确保电路快速起振且功耗较低）。
3. 环境适应性
- 工作温度：-40℃+85℃（工业级温度标准，可适应户外、车间等温差较大的场景，优于消费级晶振的0℃70℃范围）。
三、封装与物理特性
该晶振采用SMD2520-4P封装：
- 尺寸：2.5mm×2.0mm（小型化贴片封装，有效节省PCB空间，适配智能穿戴、小型通信模块等对体积要求严格的产品）；
- 引脚：4引脚设计（相比2引脚封装，抗振动性能更佳，可减少振动导致的频率偏移；引脚间距合理，自动化贴装效率高）。
四、典型应用场景
- 无线通信模块：WiFi、蓝牙、LoRa等模块的基准时钟（26MHz是此类模块的常用载波频率基准）；
- 数字处理电路：MCU、FPGA、DSP等微处理器的系统时钟（确保指令执行时序准确，提升系统稳定性）；
- 工业控制设备：PLC、传感器节点、工业物联网网关（工业级温度范围适配车间温差变化）；
- 消费电子：智能手环、智能家居控制器、小型家电（小体积封装符合产品小型化趋势）；
- 车载辅助设备：非关键部位的时钟基准（需注意：未标注AEC-Q200汽车级认证，仅适用于非高可靠性车载场景）。
五、产品优势总结
- 精度与稳定性平衡：常温±10ppm频差满足常规需求，温度范围±30ppm稳定度覆盖工业场景；
- 易集成性：12pF负载电容易匹配，40Ω ESR易起振，电路设计门槛低；
- 小型化与可靠性：SMD2520小体积，4引脚封装抗振动，适合批量自动化生产；
- 成本优势：无源晶振无需内置振荡电路，相比有源晶振成本更低，适合大规模应用；
- 环境适应性：工业级温度范围，可适应多种复杂应用场景。
该型号晶振凭借平衡的性能与成本优势，成为26MHz频率段无源晶振的主流选择之一，广泛适配各类常规及工业级电子设备。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
