0402B102K500NT是一款表面贴装多层陶瓷电容(MLCC),由风华(FH)品牌制造,规格为050V ±10% 1nF X7R,采用0402封装形式。该电容器广泛应用于高频电路和降噪电路,充分体现了多层陶瓷电容的特点与性能优势。
MLCC电容器的核心结构通常包含多个陶瓷层和电极层,通过层叠的方式实现高容量小尺寸的效果。0402B102K500NT采用了X7R类型的介质材料,这种材料具有良好的温度稳定性和较高的介电常数,使其适用于宽范围温度变化的应用场景。
稳定的电气特性:根据X7R温度特性,0402B102K500NT在-55°C至+125°C的温度范围内具备相对较小的容量变化率。这使得该电容器在不同的工作环境中依然能保持稳定的性能。
低 ESR 和 ESL:该电容器的等效串联电阻(ESR)和等效串联电感(ESL)较低,适合高频应用。这使得其在高频信号耦合和旁路应用中表现尤为出色。
小型化设计:0402的封装尺寸使其在占用空间小的情况下仍能提供极高的电容值,非常适合于空间有限的现代电子设备。
良好的抗干扰能力:该电容器能有效降低信号干扰,被广泛用于降噪和滤波电路中,以提升电路的稳定性和可靠性。
0402B102K500NT广泛应用于以下几个领域:
消费电子:在手机、平板电脑、计算机等消费类电子产品中,作为去耦电容和信号耦合电容,确保信号的完整传输。
工业设备:用于传感器、控制器和变频器等工业设备中,保证设备运行的稳定性和信号的高保真性。
汽车电子:在各种汽车电子系统中,包括动力管理、娱乐系统及安全系统,提供必需的抗干扰和降噪能力。
通信设备:用于网络设备、基站、光纤通信等高频电路,以提供稳定的电源和信号路径。
在使用0402B102K500NT时,建议注意以下几点:
焊接温度:确保焊接工艺符合标准,以免因过高温度导致电容器性能下降或损坏。
避免超负荷工作:虽然额定电压为50V,但应避免长时间在接近额定电压的条件下工作,以延长电容器的使用寿命。
环境因素:在潮湿或腐蚀性环境中使用时,应确保电容器的封装受到保护,以防止影响其性能。
频率特性:在高频应用中,合理选型并考虑该电容器的ESR和ESL特性,以满足电路设计的需求。
0402B102K500NT作为一款高性能、多用途的贴片电容器,凭借其稳定的电气特性、低ESR和小型化设计,成为现代电子产品中不可或缺的基础组件之一。无论是在消费电子、工业应用还是汽车电子领域,其卓越的性能都能提供可靠的支持,促进电子设备的高效运行。

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.
