0402CG2R5C500NT 风华贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

0402CG2R5C500NT是风华高科(FH品牌) 推出的一款小型化贴片多层陶瓷电容(MLCC),型号命名遵循行业通用规则:

  • 0402:封装规格(英制,对应公制1005),实际尺寸约1.0mm×0.5mm×0.5mm(长×宽×高);
  • CG:温度系数标识,对应国际标准C0G(即NP0);
  • 2R5:容值代码,代表标称容值2.5pF(“R”为小数点占位符);
  • 500:额定电压代码,代表直流额定电压50V;
  • NT:风华内部系列后缀,用于区分工艺版本与应用场景。

该产品属于通用级精密MLCC,广泛适配消费电子、通信、工业控制等领域的高频/精密电路。

二、核心电气性能参数

作为C0G介质MLCC,其性能核心围绕高稳定、低损耗展开:

  1. 容值特性:标称2.5pF,典型容差±0.25pF(或±0.5%),宽温范围内(-55℃~125℃)容值变化率≤±0.1%;
  2. 电压参数:直流额定电压50V,交流电压下峰值需≤50V(因C0G无极化特性,可兼容交直流);
  3. 温度系数:C0G(NP0),温度系数范围0±30ppm/℃,是目前陶瓷电容中温度稳定性最优的介质之一;
  4. 损耗特性:1kHz/25℃条件下,损耗角正切(tanδ)≤0.15%,低损耗适合高频信号传输;
  5. 等效参数:ESR(等效串联电阻)典型值≤1Ω(100MHz),ESL(等效串联电感)≤0.5nH,高频性能优异。

三、材料与结构特点

  1. C0G陶瓷介质:采用钛酸钡基无铁电陶瓷材料,无“电压-容值漂移”“温度-容值漂移”现象,避免传统X7R/X5R介质的性能衰减;
  2. 多层叠层工艺:风华自主研发的叠层技术实现电极与介质均匀交替,在0402小封装内稳定实现2.5pF容值,同时降低ESR/ESL;
  3. 端电极设计:端电极采用“镍(Ni)→ 镍锡合金(NiSn)→ 锡(Sn)”三层结构,焊接兼容性强,可适配回流焊、波峰焊等主流工艺,焊点剪切强度≥1.5N;
  4. 小型化优势:0402封装体积仅为0603封装的1/4,满足智能手机、5G模块等高密度PCB布局需求。

四、典型应用场景

因C0G的高稳定特性,该产品主要用于对容值精度、温度稳定性要求严格的场景:

  1. 射频/微波电路:5G基站射频前端滤波、蓝牙/WiFi模块匹配网络、卫星通信接收端;
  2. 精密测量设备:示波器探头、信号发生器参考电容、工业传感器信号滤波;
  3. 消费电子:智能手机LTE天线匹配、智能手表蓝牙模块、平板WiFi射频前端;
  4. 工业控制:PLC模拟量输入滤波、伺服电机编码器信号调理;
  5. 医疗设备:便携式监护仪低噪声电路、超声设备信号耦合电容。

五、可靠性与环境适应性

  1. 温度范围:工作温度-55℃125℃,存储温度-40℃85℃,符合C0G材料宽温要求;
  2. 耐环境测试:通过85℃/85%RH湿度测试(1000小时),容值变化率≤±1%;回流焊峰值260℃(持续10s)无性能衰减;
  3. 可靠性认证:符合RoHS、REACH环保标准,部分批次通过AEC-Q200(汽车电子)认证(需确认具体批次);
  4. 寿命特性:额定条件下(25℃/50V)长期工作寿命≥10^6小时,无明显容值漂移。

六、选型与使用注意事项

  1. 焊接工艺:优先采用回流焊,温度曲线需满足:预热150~180℃(2min)、升温速率≤3℃/s、峰值260±5℃(10s);波峰焊浸锡时间≤3s;
  2. 静电防护:MLCC对静电敏感(静电阈值≥100V),操作需佩戴ESD手环,使用ESD工作台;
  3. 储存要求:未开封产品存储于25±5℃、湿度≤60%环境,保质期12个月;开封后建议3个月内使用完毕;
  4. 降额使用:直流电压建议不超过额定值的80%(即40V),延长产品寿命;交流电压需计算峰值(峰值≤50V);
  5. PCB布局:焊盘尺寸建议0.6mm×0.3mm,避免靠近大功率元件(减少热应力影响),布线需短捷以降低干扰。

该产品凭借风华高科的工艺优势与C0G介质的高性能,成为精密高频电路的主流选型之一,可有效提升设备的信号稳定性与可靠性。

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
