0402B473K250NT 是一款高性能的贴片电容(多层陶瓷电容,MLCC),由知名品牌 FH(风华)制造。其封装类型为0402,符合业界标准,适合各种电子电路设计需求。这款电容的主要参数包含了47nF的容值、±10%的精度、25V的额定电压以及温度系数为X7R的材料,广泛应用于多种电子设备中。
容值:47nF(纳法拉)
这一容值在多种应用中十分常见。特别适用于高频滤波、耦合和去耦合等电路中。其适用频率范围广泛,能够在不同的电信号情况下稳定工作。
温度系数:X7R
X7R是一种钛酸锶的陶瓷材料,具有良好的温度特性。在-55°C到+125°C的环境温度范围内,其电容量变化不超过±15%。这使得0402B473K250NT能在较为恶劣的环境条件下可靠稳定地工作,适合许多温度敏感应用。
精度:±10%
该电容的容值误差为±10%,对大多数应用而言,这是一个合理的精度水平。可以满足一般电路对电容器容值的要求,对于需要严苛控制电容容值的电路,则可能需要进一步考虑更高精度的电容。
额定电压:25V
该电容的额定电压为25V,适合大多数常规电路供电环境。为保证电容在电路中的长期稳定性和可靠性,建议在实际应用中将工作电压控制在额定电压的70%-80%左右。
封装尺寸:0402
0402封装是目前较为流行的微型封装尺寸,具有占用空间小、节省布局面积等优点,适合现代电子产品对于空间的优化需求。该封装尺寸也为表面贴装技术(SMT)的应用提供了便利。

Request for quote
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.
