华新科0402N471J500CT陶瓷电容器产品概述

一、核心参数总览

华新科0402N471J500CT为表面贴装陶瓷电容器,核心参数明确适配多数精密电子电路需求:

  • 容值:470pF(标识代码“471”,即47×10¹ pF);
  • 精度:±5%(标识代码“J”,属常规精密级范围);
  • 额定电压:50V(标识代码“500”,覆盖低压至中低压电路场景);
  • 温度系数:NP0/C0G(国际通用标识,体现优异温度稳定性);
  • 封装:0402英制(对应公制1005,尺寸紧凑);
  • 品牌:华新科(Walsin,全球知名被动元件制造商)。

补充参数:典型工作温度范围-55℃~125℃,1kHz下损耗角正切(tanδ)≤0.001,无极性设计。

二、关键性能特性

该产品核心优势源于NP0/C0G材质特性,在稳定性与高频性能上表现突出:

  1. 温度稳定性优异:NP0/C0G温度系数≤±30ppm/℃,-55℃至125℃宽温范围内容值变化极小(远低于X7R、Y5V材质),适合对容值精度要求高的场景;
  2. 高频损耗极低:tanδ≤0.001(1kHz),射频(RF)、微波电路中可有效减少信号衰减,提升传输效率;
  3. 电压稳定性好:额定电压(50V)以内容值随电压波动可忽略,避免电路性能因电压变化偏移;
  4. 无极性安装:无正负极之分,焊接无需区分方向,简化生产工艺,降低安装错误风险。

三、封装与尺寸规格

采用0402英制表面贴装封装(对应公制1005),适配小型化电子设备:

  • 封装尺寸:长度1.02mm(0.04英寸)、宽度0.51mm(0.02英寸)、厚度0.50mm(典型值,以datasheet为准);
  • 焊盘设计:两端焊盘适配标准回流焊工艺,焊接可靠性高,兼容多数SMT生产线;
  • 封装材料:阻燃环氧树脂封装,符合UL94 V-0阻燃等级,提升电路安全性。

四、典型应用场景

因NP0/C0G的稳定特性与低损耗,该产品广泛应用于:

  1. 高频振荡电路:晶振负载电容、射频振荡器、锁相环(PLL)电路,需稳定容值维持振荡频率精度;
  2. 射频滤波与耦合:射频前端滤波、信号耦合电路,低损耗减少信号衰减,保证传输质量;
  3. 精密计时电路:RC计时电路、实时时钟(RTC)辅助电路,容值稳定确保计时准确性;
  4. 医疗与测试设备:医疗监护仪、示波器等精密仪器,对元件稳定性与精度要求严苛;
  5. 小型化消费电子:智能手机、蓝牙耳机、智能穿戴设备的射频模块,适配0402封装的小型化需求。

五、可靠性与品质保障

华新科对该产品可靠性管控严格:

  • 环保合规:符合RoHS 2.0、REACH等国际标准,无铅无卤,适配绿色制造;
  • 可靠性测试:通过高温老化(125℃/1000h)、湿度测试(85℃/85%RH/1000h)、振动冲击(10~2000Hz/1.5g)等,保证长期稳定性;
  • 品质一致性:先进陶瓷介质成型工艺确保批量产品参数一致,减少电路调试难度。

六、选型匹配建议

需结合电路需求匹配:

  • 电压适配:50V额定电压适用于5V、12V、24V电路,若电压高于50V需选更高额定电压型号;
  • 精度匹配:±5%满足常规精密应用,若需更高精度(如±1%),可选华新科同系列高精度型号;
  • 材质替代:成本敏感但无需高频稳定,可考虑X7R材质(注意温度/电压对容值的影响);需大容值则选Y5V材质(稳定性更差)。

该产品凭借稳定的性能、紧凑的封装与可靠的品质,成为小型化精密电子设备的理想选择。

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
