型号“0402N120J500CT”是华新科(Walsin)对该陶瓷电容器的标准化命名,各字符对应核心属性如下:
该产品属于NP0(C0G)型多层陶瓷电容器(MLCC),核心参数及意义如下:
标称容值12pF,精度±5%(J档),满足大多数精密电路对容值一致性的要求,避免因容值偏差导致的信号偏移。
50V直流额定电压,适用于低压至中压电路(需注意:交流电压需按有效值降额使用,通常取额定直流电压的70%以下)。
NP0是IEC命名,C0G是EIA命名,两者为同一材料体系:
高频下等效串联电阻(ESR)低(典型值<1Ω at 1MHz),等效串联电感(ESL)小,减少信号损耗,适合射频电路应用。
采用0402封装(公制1005),具体尺寸(以华新科 datasheet 为准):
该封装体积小、集成度高,可大幅减少PCB占用面积,满足智能穿戴、射频模块等小型化设备的设计需求。
华新科(Walsin)作为全球被动元件龙头厂商,该产品工艺具备以下优势:
采用高纯度NP0陶瓷粉,多层叠层工艺(MLCC),每层陶瓷介质厚度均匀,确保容值稳定性;端电极采用“镍底层+锡表层”,无铅环保(符合RoHS、REACH标准),焊接兼容性强(回流焊温度范围220℃~260℃)。
因NP0电容的高稳定性、低损耗特性,该产品主要应用于以下领域:
该产品核心价值在于**“稳定、高效、小型化”**:
作为华新科经典的NP0系列MLCC,0402N120J500CT凭借平衡的性能与成本,成为射频、精密仪器等领域的主流选择。

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.
