0402B474K100NT是风华电子(FH) 推出的一款0402封装多层陶瓷贴片电容(MLCC),核心参数清晰明确:
型号字符分解:0402(封装代码)、B(MLCC材质/系列标识)、474(容值代码)、K(精度代码)、100(电压代码)、NT(风华内部封装/无铅工艺标识)。
X7R温度系数是该产品的核心优势:在-55℃至+125℃的宽温度范围内,容值波动控制在±15%以内,可有效避免因温度变化导致的电路性能漂移,适配工业级、消费级设备的多样化环境需求。
±10%的K级精度,结合风华自动化生产工艺,产品批次间容值偏差小,一致性高,可降低电路设计中的容值风险,尤其适合对滤波、耦合效果有稳定要求的场景。
0402封装(1005公制)是小型化电子设备的主流选择,体积仅为传统插件电容的1/10左右,可显著提升电路集成密度,适配智能手机、智能手表等紧凑空间的设计需求。
10V DC额定电压虽为低电压规格,但覆盖了绝大多数消费电子、IoT设备的电源系统(如3.3V、5V电源滤波)需求,同时避免了高电压规格带来的体积和成本冗余。
该产品因体积小、容值稳定、电压适配性强,广泛应用于以下领域:
风华电子(FH)是国内被动元器件龙头企业,拥有30余年MLCC生产经验,0402B474K100NT具备以下品质保障:
该产品是低电压、小型化电路的高性价比选择,可满足消费电子、IoT等领域的多样化需求。

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.
