华新科(Walsin)推出的0402N100J500CT是一款NP0/C0G类高频陶瓷电容器,专为精密电子电路的稳定信号传输与滤波设计。其采用0402英制封装(对应公制1005尺寸),兼具小型化与高性能特性,广泛应用于通信、消费电子、工业控制等领域。
0402N100J500CT的型号命名遵循行业通用规则,核心标识清晰对应关键参数:
该产品符合RoHS 2.0、REACH等环保标准,无铅无镉,可满足全球市场合规要求。
标称容值10pF,精度为**±5%(J档)。NP0介质的核心优势是容值超稳定**——在-55℃125℃宽温范围、050V电压范围内,容值变化≤0.03%,不受频率(1kHz~1GHz)影响,完美适配对容值一致性要求严苛的精密电路。
直流额定电压50V,可覆盖中等电压场景(如射频电源滤波、模拟信号调理)。与X7R等普通陶瓷电容不同,NP0类电容的电压系数极低(≤0.01%/V),容值随电压变化可忽略,避免电路性能漂移。
温度系数为NP0(C0G),定义为≤±30ppm/℃(行业标准)。这意味着在极端温度下,容值变化不超过0.03%,是高频通信、时钟振荡电路的理想选择。
损耗角正切值(tanδ)典型值≤0.15%@1kHz,品质因数(Q值)≥600@1MHz。低损耗特性可减少信号传输中的能量衰减,提升射频电路的信噪比与通信距离。
0402封装(公制1005)的具体尺寸(单位:mm):
该封装具有三大优势:
0402N100J500CT的性能特点使其适用于以下核心场景:
该产品凭借稳定的性能与小型化设计,成为众多电子设备中高频、精密电路的优选电容之一。华新科提供完整的技术支持与样品服务,可满足不同客户的研发与生产需求。

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.
