华新科0402N101J500CT陶瓷电容器产品概述

一、产品核心参数与标识解析

华新科0402N101J500CT是一款C0G/NP0温度稳定型陶瓷电容器,型号命名清晰对应各项关键参数:

  • 0402:英制封装尺寸(0.04英寸×0.02英寸),对应公制1005(1.0mm×0.5mm);
  • N:华新科NP0系列专属标识;
  • 101:容值代码(10×10¹=100pF);
  • J:精度等级(EIA标准,对应±5%容值误差);
  • 500:额定直流电压(DC 50V);
  • CT:尾缀关联产品材质特性与包装(如卷带封装适配自动化贴装)。

核心参数汇总:

参数项 规格值 标称容值 100pF 容值精度 ±5% 额定电压(DC) 50V 温度系数 C0G(EIA)/NP0(IEC) 封装类型 0402(SMD表面贴装) 品牌 华新科(Walsin)

二、关键特性与材料优势

这款电容器的核心竞争力源于C0G/NP0陶瓷介质的特性,结合华新科的工艺优势:

  1. 超宽温容值稳定性:在-55℃至125℃范围内,容值漂移率≤±30ppm/℃,几乎不受温度变化影响,是对容值精度要求极高场景的首选;
  2. 低损耗与高Q值:介电损耗极低(典型值<0.001),在射频(RF)、微波频段信号传输损耗小,适合5G、蓝牙等高频电路;
  3. 高可靠性与一致性:采用精密陶瓷成型及银电极工艺,批量产品容值、电压特性偏差极小,长期老化率<0.5%/1000小时;
  4. 无极性设计:无需区分正负极,贴装和电路设计更便捷,降低出错概率。

三、封装与尺寸规格

0402封装属于小型化表面贴装封装,适配高密度PCB布局,具体尺寸(参考IPC标准):

  • 封装长度:1.0±0.1mm(0.04±0.004英寸);
  • 封装宽度:0.5±0.1mm(0.02±0.004英寸);
  • 焊盘尺寸建议:0.3mm×0.3mm(适配常规PCB设计);
  • 典型厚度:0.5±0.1mm。

该封装支持自动化高速贴装(贴装速度可达15000点/小时),同时陶瓷封装具有良好的机械强度,抗振动(10Hz~2000Hz,10g加速度)、抗冲击(1000g,0.5ms)性能优于薄膜电容。

四、典型应用场景

0402N101J500CT因温度稳定、低损耗特性,广泛应用于以下领域:

  1. 射频/微波电路:手机4G/5G射频前端(滤波、耦合、谐振)、蓝牙/WiFi模块信号匹配;
  2. 通信设备:基站收发器、路由器、交换机的高频滤波网络;
  3. 消费电子:智能穿戴(手表、耳机)时钟电路、电源滤波;
  4. 工业控制:PLC、传感器模块的稳定振荡电路(对温度敏感的时序控制);
  5. 测试仪器:示波器、信号发生器的校准电路(需高精度稳定容值)。

五、可靠性与环境适应性

华新科该产品符合工业级可靠性标准,环境适应性表现优异:

  • 工作温度:-55℃~125℃(满足车规级基础要求,若需车规可定制);
  • 焊接适应性:支持回流焊(260℃±5℃,30秒内)、波峰焊(240℃±5℃,5秒内);
  • 湿度稳定性:85℃/85%RH环境下存储1000小时后,容值变化≤±1%,绝缘电阻≥10⁹Ω;
  • 长期可靠性:经1000小时高温老化(125℃)后,性能无明显衰减。

六、使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即40V),避免长期过压导致介质老化;
  2. 静电防护:陶瓷电容器对静电敏感,存储、运输需用防静电包装,贴装时需接地工作台;
  3. 焊接工艺:遵循华新科推荐的回流焊温度曲线,避免局部过热(如峰值温度超过265℃);
  4. 存储条件:常温(15℃~35℃)、干燥(湿度≤60%)环境下存储,避免阳光直射及腐蚀性气体。

综上,华新科0402N101J500CT是一款高精度、高稳定、小型化的陶瓷电容器,适合对容值温度特性要求严格的高频电路,在消费电子、通信、工业控制等领域具有广泛应用价值。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
