TXM24M0004252FBCEO00T是雅晶鑫(YJX)推出的一款无源贴片晶振,型号中“24M”明确核心频率为24MHz,“SMD2520-4P”代表采用2.5mm×2.0mm的4引脚贴片封装,属于小型化时钟源器件。无源晶振区别于有源晶振(内置振荡电路),需外接匹配电容和振荡电路起振,具有成本低、体积小、抗干扰性强的特点,是电子设备中最常用的基础时钟元件之一。
推荐负载电容12pF,无源晶振的振荡频率由晶体特性与外接负载电容总和决定(需包含PCB杂散电容,约1-3pF)。设计时需确保外接陶瓷电容(如10pF+2pF)与杂散电容之和接近12pF,否则会导致频率偏移超出规格。
ESR为55Ω,是晶振振荡时的能量损耗指标:ESR越小,振荡电路(如反相器、时钟芯片)越容易起振。55Ω处于常规无源晶振的合理范围,可避免因ESR过大导致起振困难或振荡不稳定。
采用SMD2520-4P贴片封装,尺寸为2.5mm(长)×2.0mm(宽)×0.8mm(典型厚度),4引脚布局符合行业标准,适配自动化SMT贴装工艺(回流焊温度≤260℃)。封装材料为耐高温陶瓷,引脚采用抗氧化镀层,可降低焊接不良率,同时满足小型化设备的PCB空间需求。
TXM24M0004252FBCEO00T以24MHz核心频率、工业级温度范围、小型化贴片封装为核心优势,兼顾成本与性能,是工业控制、消费电子、物联网等领域的高性价比时钟源选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
