0402CG2R7B500NT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性

0402CG2R7B500NT是风华高科(FH) 推出的一款高频贴片多层陶瓷电容(MLCC),核心定位为对容值稳定性、损耗要求较高的电子电路。产品型号中各字符含义:

  • 0402:英制封装规格(长度0.04英寸×宽度0.02英寸);
  • CG:介质类型标识(C0G/NP0,温度系数稳定型);
  • 2R7:标称容值2.7pF(“R”代表小数点);
  • B500:额定直流电压50V;
  • NT:端电极及包装特性(无铅环保、卷带编带)。

二、核心性能参数

1. 容值与精度

标称容值为2.7pF,常见容差分两种版本:

  • 高精度版:±0.25pF(适合谐振、精密滤波);
  • 通用版:±5%(适合耦合、旁路等普通场景);
    需根据具体批次的 datasheet 确认实际精度。

2. 温度特性

采用C0G(NP0)介质,符合EIA标准温度系数:

  • 温度系数范围:0±30ppm/℃;
  • 宽温稳定性:-55℃~+125℃范围内,容值变化率≤0.003%/℃(即容值波动≤0.0081pF),是高频电路的理想选择。

3. 损耗与耐压

  • 损耗角正切(tanδ):1kHz下≤0.15%,100MHz下≤0.2%(高频低损耗特性);
  • 额定电压:50V DC(直流应用),交流应用需按有效值降额(通常降额至额定的70%);
  • 耐焊接热:回流焊峰值温度260℃(持续10s),符合IPC-J-STD-020标准。

4. 工作条件

  • 工作温度:-55℃~+125℃(覆盖工业级与消费电子宽温需求);
  • 存储温度:未开封产品15℃35℃、湿度40%60%,开封后建议1年内使用完毕。

三、封装与尺寸规范

1. 封装尺寸

  • 英制:0402(0.04in×0.02in);
  • 公制:1005(1.0mm×0.5mm);
  • 实际尺寸(含端电极):长1.0±0.1mm × 宽0.5±0.1mm × 高0.5±0.1mm。

2. 端电极与包装

  • 端电极:无铅环保(Sn-Cu-Ni三元合金),兼容无铅回流焊工艺;
  • 包装形式:卷带编带(Tape & Reel),标准包装数量10000pcs/卷,适配自动化贴装设备。

四、典型应用场景

该产品凭借C0G的稳定特性和小体积封装,广泛应用于以下领域:

  1. 高频射频电路:蓝牙、WiFi、5G sub-6GHz模块中的耦合、滤波、谐振回路(低损耗避免信号衰减);
  2. 消费电子:智能手机、平板电脑、智能手表的射频前端、天线匹配网络(小体积适配便携设备);
  3. 工业控制:PLC、传感器模块的高频信号滤波(宽温稳定满足工业环境);
  4. 通信设备:基站射频单元、光模块的信号耦合电容(低损耗保障信号传输质量);
  5. 汽车电子:车载导航、车联网的射频模块(部分批次通过AEC-Q200认证,可用于车规场景)。

五、品牌与可靠性保障

1. 品牌背景

风华高科是国内MLCC龙头企业,拥有20余年陶瓷电容研发生产经验,产品覆盖通用、高频、高压等全系列,符合RoHS 2.0、REACH等环保标准。

2. 可靠性认证

  • 通用级:符合IEC 60384-1电子元件通用标准;
  • 车规级(部分批次):通过AEC-Q200认证,满足汽车级可靠性要求;
  • 质量控制:全自动生产+100%参数抽检,不良率控制在ppm级。

六、选型与使用注意事项

  1. 电压降额:实际工作直流电压建议≤40V(额定的80%),交流电压需按有效值降额至35V以内;
  2. 精度匹配:谐振回路、精密滤波优先选±0.25pF版本,通用耦合可选±5%版本;
  3. PCB布局:0402封装焊盘建议设计为长0.6mm×宽0.3mm,避免焊盘过大导致桥接或过小导致虚焊;
  4. 温度确认:若应用于汽车级(-40℃~+125℃),需确认产品是否通过AEC-Q200认证。

该产品以稳定的高频性能、小体积封装和高可靠性,成为射频、通信等领域的常用选型,可满足大多数对容值精度和温度稳定性要求较高的电路设计需求。

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
