TX50328M2FDCE1T是雅晶鑫(YJX)推出的SMD5032-2P封装通用型贴片晶振,核心频率为8MHz,专为中小体积、对时钟稳定性有基础要求的电子设备设计。其关键参数覆盖主流应用场景:
该晶振采用SMD5032-2P小型化贴片封装(尺寸约5.0mm×3.2mm×1.2mm),无传统引线设计,适配自动化SMT生产线,焊接效率高且一致性好。2引脚结构简化了电路连接,同时减少了寄生参数对时钟信号的干扰;封装材料选用耐高温陶瓷,可承受回流焊等高温制程(峰值温度≤260℃),抗机械振动性能优于直插型晶振,适合便携式设备或高密度PCB布局场景。
核心频率8MHz为基频输出,无需额外泛音电路,信号纯净度高。常温频差±20ppm满足大多数数字电路(如MCU、单片机)的时钟精度要求;全温范围(-40~85℃)频率稳定度±30ppm,可覆盖户外设备、工业传感器等场景的温度波动。
默认负载电容12pF,电路设计时需注意:PCB寄生电容(通常1~3pF)需计入总负载,实际外接电容应选择12pF减去寄生电容值(如寄生2pF则选10pF),否则会导致频偏超出规格。
典型值80Ω,属于同频率同封装晶振的常规水平。需注意振荡电路的放大倍数需≥5倍ESR对应的损耗,避免因ESR过大导致停振或输出幅度不足。
该晶振因体积小、稳定性好,广泛应用于:
TX50328M2FDCE1T兼顾小体积与可靠性,是消费电子、工业、通信等领域的高性价比时钟源选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
