KEMET C0402C220K5GACTU 多层陶瓷电容器产品概述

KEMET(基美)C0402C220K5GACTU是一款0402封装的C0G(NP0)特性多层陶瓷电容器,专为高频、精密电子系统设计,兼具小型化、高稳定性与高可靠性,广泛应用于射频通信、医疗电子等场景。

一、产品基本属性

该型号的核心参数可通过标识明确拆解,关键信息如下:

项目 具体参数 完整型号 C0402C220K5GACTU 制造商 KEMET(基美) 封装尺寸 0402(英制,对应公制1005,实际尺寸:1.0mm×0.5mm×0.5mm) 标称容值 22pF 精度等级 ±10%(标识代码“K”) 额定电压 50V DC(连续工作电压上限) 温度系数 C0G(符合EIA RS-198标准,对应IEC NP0特性) 工作温度范围 -55℃ ~ +125℃(典型值)

二、核心技术特性

C0G(NP0)是该产品的核心技术亮点,区别于X7R、Y5V等温度系数较大的陶瓷材料,优势集中在容值稳定性、高频性能两个维度:

  1. 容值超稳定:温度系数≤±30ppm/℃,即-55℃至+125℃范围内,容值偏差仅约0.3%;电压系数≤0.01%/V,容值随工作电压变化可忽略,适合对精度敏感的电路。
  2. 低损耗高频适配:介质损耗角正切(DF)≤0.15%(1kHz下),高频阻抗特性优异,支持100MHz以上射频电路应用,无明显信号衰减。
  3. 无极性与环保:多层陶瓷结构无极性,焊接无需区分正负;符合RoHS、REACH标准,无铅无卤,适配现代电子制造工艺。

三、封装与可靠性验证

0402封装是该产品的关键设计,兼顾小型化与可靠性:

  • 体积紧凑:相比0603封装体积减少约60%,适配智能手机、可穿戴设备等高密度PCB设计。
  • 多环境可靠性:KEMET对该系列进行了严格验证,包括:
    • 温度循环测试(-55℃~+125℃,1000次循环);
    • 湿度老化测试(85℃/85%RH,1000小时);
    • 振动测试(10~2000Hz,加速度2g); 满足工业级与消费电子级应用的可靠性要求,寿命可达10万小时以上(25℃/额定电压下)。

四、典型应用场景

由于C0G的高频稳定特性,该产品主要用于对容值精度要求高的场合:

  1. 射频通信模块:手机、WiFi 6、蓝牙5.0等设备的滤波、耦合电容,保证信号传输无失真;
  2. 精密模拟电路:运算放大器、ADC/DAC的去耦电容,减少噪声干扰,提升采样精度;
  3. 高频振荡器:晶体振荡器(XO)、压控振荡器(VCO)的负载电容,稳定振荡频率(偏差≤0.1%);
  4. 医疗电子设备:超声诊断仪、心电图仪的信号调理电路,确保测量数据准确;
  5. 工业控制通信:PLC、工业以太网模块的高频耦合电容,适应-40℃~+85℃的宽温环境。

五、选型与应用注意事项

  1. 精度匹配:若需更高精度,可选择同系列型号:
    • ±5%:C0402C220J5GACTU(代码“J”);
    • ±1%:C0402C220F5GACTU(代码“F”);
  2. 电压降额:建议实际工作电压不超过额定电压的80%(即40V),延长使用寿命;
  3. 焊接工艺:0402封装焊接温度需控制在回流焊230~260℃(峰值),时间≤10秒,避免热应力导致电容开裂;
  4. 存储要求:未开封产品存储在25±5℃、40~60%RH环境,开封后12个月内使用完毕。

该产品作为KEMET C0G系列的经典型号,平衡了小型化与高稳定性,是高频精密电子设计的可靠选择,广泛应用于消费电子、工业控制、医疗等领域。

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
