风华0402CG0R5C500NT 多层片式陶瓷电容(MLCC)产品概述

一、产品基本属性与型号定义

0402CG0R5C500NT是风华高科(FH)推出的超稳定型MLCC,核心属性与型号命名逻辑如下:

  • 核心参数:容值0.5pF、额定电压50V DC、温度系数C0G、封装0402;
  • 型号拆解:
    0402=英制封装代码(公制1.0×0.5mm);CG=IEC标准C0G介质命名;0R5=0.5pF(R代小数点);500=50V额定电压;NT=风华内部工艺代码。

该型号采用成熟叠层工艺,专为高频、高精度、温度稳定的电路场景设计,属于Class 1陶瓷介质范畴。

二、封装与机械尺寸规格

0402封装是小型化贴片电容的主流规格,公制典型尺寸(含电极):

  • 长度(L):1.0±0.1mm;
  • 宽度(W):0.5±0.1mm;
  • 厚度(T):0.5±0.1mm;
  • 电极镀层:镍-锡无铅合金(RoHS compliant)。

封装优势:体积紧凑(仅为0603封装的1/4),适配高密度PCB设计(最小焊盘间距0.2mm),适合便携设备及小型化模块。

三、核心电气性能参数

基于C0G介质的超稳定特性,关键电气参数(25℃、1kHz测试条件):

参数 典型值/额定值 备注 额定电压(Vdc) 50V 直流工作电压上限 标称容值(C) 0.5pF 精密小容值设计 容值精度 ±0.05pF(±10%) 小容值C0G的高精度要求 损耗角正切(DF) ≤0.0005(0.05%) 高频损耗极低 绝缘电阻(IR) ≥10^12Ω 25℃、50V直流测试 工作温度范围 -55℃ ~ +125℃ 工业级温度适应性

注:容值随温度变化率≤±0.015pF(对应温度系数0±30ppm/℃),是Class 1介质中最稳定的类型。

四、C0G介质的核心优势

C0G(NP0)是MLCC中温度稳定性最优的介质,区别于X7R/Y5V等Class 2介质,核心优势:

  1. 容值温度漂移极小:-55℃~+125℃范围内,容值变化≤±3%,远优于X7R的±15%;
  2. 高频损耗极低:DF≤0.05%,适合1GHz以上射频电路,避免信号衰减;
  3. 无直流偏置效应:Class 2介质会因电压升高导致容值下降,而C0G无此问题,适合精密匹配网络;
  4. 长期可靠性:介质老化率可忽略(≤0.1%/1000小时),适合长寿命应用。

五、典型应用场景

该电容因小体积、高稳定、低损耗,广泛用于以下领域:

  1. 射频通信:WiFi 6/6E、蓝牙5.2、5G基站的滤波、阻抗匹配、耦合电路;
  2. 精密仪器:示波器、信号发生器、频谱分析仪的高频信号调理;
  3. 消费电子:高端TWS耳机、智能手表的射频前端模块;
  4. 工业控制:高精度传感器(压力/温度传感器)的信号滤波;
  5. 汽车电子:车载通信(CAN/LIN)的EMC滤波(部分批次满足AEC-Q200汽车级标准)。

六、可靠性与环境认证

风华0402CG0R5C500NT通过多项可靠性测试及环境认证:

  • 可靠性测试:
    • 振动:10~2000Hz,1.5mm双振幅,2小时,无开路/短路;
    • 冲击:1500g加速度,0.5ms脉冲,三次,性能无下降;
    • 寿命测试:125℃、50V DC,1000小时,容值变化≤±0.1%,IR≥10^11Ω;
  • 环境认证:
    • RoHS 2.0(无铅、无镉、无汞);
    • REACH合规;
    • 部分批次满足AEC-Q200(汽车电子级,需向供应商确认)。

七、使用与选型注意事项

  1. 焊接工艺:
    • 回流焊:峰值温度245±5℃,峰值时间≤10s,升温速率≤3℃/s;
    • 波峰焊:温度260±5℃,过炉时间≤5s(避免多层板热应力);
  2. 机械应力:0402封装易开裂,焊接后避免PCB弯折(曲率半径≥100mm);
  3. 存储条件:温度-10~40℃,湿度≤60%,开封后12个月内使用(未开封保质期24个月);
  4. 选型扩展:若需更高耐压(100V)或更大容值(1pF),可选择同系列0402CG1R0C100NT。

该型号凭借C0G介质的超稳定特性,成为高频精密电路的首选元件,兼顾小型化与可靠性,适配多领域应用需求。

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
