风华0402CG2R4C500NT是一款多层片式陶瓷电容(MLCC),由国内电子元器件龙头企业风华高科(FH品牌)研发生产。型号严格对应核心参数:
容值为2.4pF,因采用C0G(NP0)介质,容值公差控制在**±0.25pF**(典型值),远优于普通陶瓷电容,可满足精密电路对容值一致性的要求。
直流额定电压为50V,交流应用需注意:交流峰值电压不得超过50V,长期工作建议降额至额定电压的80%以下,避免介质击穿。
C0G是陶瓷电容中温度稳定性最优的介质类型:
采用0402(英制)/1005(公制) 小封装,物理尺寸(典型值):
相较于X7R、Y5V等介质,C0G类MLCC具备三大突出优势:
0402封装体积小、重量轻,可显著压缩PCB布局空间,适配智能手机、智能手表等便携式设备的高密度集成。
采用镍电极无铅工艺,电极与陶瓷介质结合紧密,可靠性表现:
符合RoHS 2.0、REACH标准,无铅、无卤素,满足全球市场环保要求。
该产品因高精度、高稳定、小体积的特点,广泛应用于:
风华高科拥有30余年MLCC研发生产经验,针对该产品:
该产品兼顾高精度、高可靠性与小型化,是射频通信、精密电子领域的理想选型。

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.
