0201B331K500NT是风华电子(FH) 推出的通用型多层陶瓷贴片电容(MLCC),采用0201英制封装,针对小型化、高频电路设计,兼顾容值密度与温度稳定性,适用于消费电子、物联网等中低电压场景,是行业内高性价比的通用电容选型之一。
容值标称330pF(标注代码“331”,即33×10¹pF),精度等级为**±10%**(代码“K”),满足多数电路对容值的基本需求,无需高精度(如±5%)时可降低成本。
采用0201英制封装(对应公制尺寸约0.6mm×0.3mm),产品厚度为0.3mm±0.02mm,体积极小,适配高密度PCB布局需求。
以钛酸钡(BaTiO₃)为基础的陶瓷介质,介电常数约2000~3000,介于NPO(C0G,低容值、高稳定)与Y5V(高容值、温度敏感性强)之间,兼顾容值密度与温度稳定性,是通用MLCC的主流介质选择。
采用高精度叠层工艺:陶瓷介质层与镍(Ni)电极交替叠放,经高温烧结形成一体化结构,无引线寄生电感,高频性能优异;同时电极与介质结合紧密,电性能稳定、可靠性高。
风华电子是国内MLCC行业龙头,产品符合RoHS 2.0、REACH等环保标准,生产工艺通过ISO 9001认证,批次一致性好,供货稳定。

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.
