风华FH品牌的0402CG331J500NT是一款针对通用电子电路设计的C0G温度系数贴片多层陶瓷电容(MLCC),以小体积、高稳定性、宽电压覆盖为核心特点,适配小型化、高精度及中低压应用场景。以下从多维度解析其产品特性与应用价值:
型号各字符对应明确的技术参数,可快速识别核心属性:
该产品定位为通用型高频稳定MLCC,兼顾体积与性能,适用于消费电子、工业控制、射频通信等领域。
330pF容值处于中频段电容范围,可有效滤除10MHz~1GHz频段的干扰信号;±5%精度在批量应用中一致性优异,避免因容值偏差导致电路性能波动(如滤波截止频率偏移)。
50V DC额定电压高于常见低压应用(3.3V/5V),实际使用建议降额至75%以内(即≤37.5V),可显著延长产品寿命,降低高温/湿度环境下的失效风险。
C0G介质的核心优势是温度稳定性极优:温度系数为0±30ppm/℃(-55℃~+125℃宽温范围),容值随温度/频率变化极小;同时损耗角正切(tanδ)≤0.15%(1kHz/25℃),高频下信号损耗低,适合射频电路信号耦合。
尺寸仅1.0mm×0.5mm×0.5mm(典型厚度),可大幅节省PCB空间,适配智能手表、蓝牙耳机、IoT传感器等微型电子设备;封装引脚间距0.3mm,兼容常规SMT贴装设备(如富士、西门子贴片机)。
采用多层陶瓷介质+镍内电极+锡铅/纯锡外电极结构:
作为国内MLCC领域老牌厂商,风华电子的产品通过ISO9001质量体系认证,批次一致性达行业领先水平;部分批次满足AEC-Q200工业级可靠性标准,可用于汽车电子(如车载蓝牙模块)、工业控制等严苛场景。
符合欧盟RoHS 2.0(无铅、无镉、无汞)及REACH法规,外电极采用无铅锡层,适配绿色制造需求;同时通过UL认证,电气安全性能符合国际标准。
该产品以平衡的性能与成本优势,成为中低压、高精度电路的优选MLCC,可满足多数电子设备的小型化与可靠性需求。

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.
