风华0402CG2R4C500NT 多层片式陶瓷电容(MLCC)产品概述

一、产品基本定义

风华0402CG2R4C500NT是一款多层片式陶瓷电容(MLCC),由国内电子元器件龙头企业风华高科(FH品牌)研发生产。型号严格对应核心参数:

  • 前缀“0402”:英制封装尺寸(公制对应1005);
  • “CG”:温度系数标识,对应EIA标准的C0G(NP0) 类;
  • “2R4”:容值标识(“R”代表小数点),即2.4pF;
  • “500”:额定电压标识,即50V直流(DC);
  • 后缀“NT”:无铅环保封装后缀。

二、核心参数全解析

1. 容值与精度

容值为2.4pF,因采用C0G(NP0)介质,容值公差控制在**±0.25pF**(典型值),远优于普通陶瓷电容,可满足精密电路对容值一致性的要求。

2. 额定电压

直流额定电压为50V,交流应用需注意:交流峰值电压不得超过50V,长期工作建议降额至额定电压的80%以下,避免介质击穿。

3. 温度特性

C0G是陶瓷电容中温度稳定性最优的介质类型:

  • 温度系数:±30ppm/℃(-55℃~+125℃范围内);
  • 容值变化率:宽温区间内≤0.3%(以25℃为基准),无明显漂移;
  • 损耗特性:1kHz下损耗角正切(tanδ)≤0.0001,高频信号损耗极小。

4. 封装尺寸

采用0402(英制)/1005(公制) 小封装,物理尺寸(典型值):

  • 长度:1.0±0.1mm;
  • 宽度:0.5±0.1mm;
  • 厚度:0.5±0.1mm;
  • 焊盘间距:0.3±0.1mm。

三、C0G介质的核心优势

相较于X7R、Y5V等介质,C0G类MLCC具备三大突出优势:

  1. 超高稳定性:无老化效应,长期使用(>10年)容值变化率≤0.5%,适合精密仪器;
  2. 低损耗:高频下能量损耗极小,提升射频电路信号完整性;
  3. 宽温适用:-55℃~+125℃工作范围,满足工业级、车载级恶劣环境需求。

四、封装与可靠性设计

1. 小型化适配

0402封装体积小、重量轻,可显著压缩PCB布局空间,适配智能手机、智能手表等便携式设备的高密度集成。

2. 工艺可靠性

采用镍电极无铅工艺,电极与陶瓷介质结合紧密,可靠性表现:

  • 耐焊接热:260℃回流焊3次(符合IPC标准)后无开裂、脱层;
  • 湿度耐久性:85℃/85%RH环境下1000h测试,容值变化率≤1%,绝缘电阻≥10^10Ω;
  • 机械强度:抗0.5mm半径弯折10次、抗10~2000Hz振动(加速度2g)。

3. 环保认证

符合RoHS 2.0、REACH标准,无铅、无卤素,满足全球市场环保要求。

五、典型应用场景

该产品因高精度、高稳定、小体积的特点,广泛应用于:

  1. 射频通信:蓝牙5.0、WiFi 6模块、5G基站射频前端,用于滤波、耦合、阻抗匹配;
  2. 精密模拟电路:音频DAC、传感器信号调理、医用电子设备,保证信号精度;
  3. 时钟与振荡器:晶体振荡器(XO)、压控振荡器(VCO)、PLL锁相环,稳定时钟频率;
  4. 小型化终端:智能手机主板、智能手环、智能家居传感器节点。

六、品牌与品质保障

风华高科拥有30余年MLCC研发生产经验,针对该产品:

  • 全流程质控:自动化生产线100%在线检测,每批次通过容值、耐压、温度特性测试;
  • 供货保障:年产能超1000亿只,满足批量订单需求;
  • 技术支持:提供电路设计参考、选型指导,售后响应及时。

该产品兼顾高精度、高可靠性与小型化,是射频通信、精密电子领域的理想选型。

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
