TDK CGA2B2C0G1H020CT0Y0F 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本属性与核心参数

该产品为TDK旗下1类高频精密多层陶瓷贴片电容(MLCC),属于CGA系列核心产品,核心参数完全匹配高频精密电路需求,具体如下:

  • 容值规格:2pF(标称值),精度等级为±5%(小容值场景下实际偏差控制在±0.1pF以内,满足精密电路匹配要求);
  • 额定电压:50V DC(直流额定电压,兼容低功率AC场景,无额外降额要求);
  • 温度系数:C0G(对应IEC 60384-1标准的1类介质,温度系数范围**-30ppm/℃~+60ppm/℃**,宽温稳定性优异);
  • 封装形式:0402(英制封装,公制尺寸1005,即长1.0mm±0.2mm、宽0.5mm±0.2mm);
  • 环保认证:符合RoHS 2.0、REACH法规,无铅无卤,满足全球电子设备环保要求。

二、封装与尺寸规格

0402封装是当前电子设备小型化的主流选择,该产品的封装设计兼顾高密度布局与可靠性:

  • 外形尺寸:长1.0mm、宽0.5mm、厚0.5mm(典型值,公差±0.1mm),适配0.4mm pitch以下的PCB;
  • 端电极结构:采用银-镍-锡三层复合电极,兼容回流焊、波峰焊工艺,焊接强度符合IPC J-STD-020标准;
  • 应力缓冲设计:端电极边缘做圆角处理,减少焊接热应力对陶瓷介质的冲击,降低开裂风险。

三、介质材料与温度稳定性

该产品采用C0G(NP0)陶瓷介质,是1类介质电容的典型代表,核心优势源于材料特性:

  • 宽温稳定性:在-55℃~125℃范围内,容值变化率≤±0.05%(以25℃为基准),远优于2类介质(如X7R的±15%),适合航空航天、工业控制等宽温场景;
  • 无压电效应:1类介质无铁电性,工作时无机械振动噪声,避免对音频、射频电路造成干扰;
  • 低高频损耗:介质损耗角正切(tanδ)≤0.15%(1kHz、25℃测试),在数十GHz频段仍保持低损耗,满足5G、WiFi 6等高频需求。

四、电气性能与典型应用

基于C0G介质的优异特性,该产品在电气性能上表现突出,适配多类精密高频场景:

  • 绝缘电阻:25℃、50V DC条件下,绝缘电阻≥10^12Ω,长期工作无漏电流问题;
  • 谐振特性:2pF小容值配合0402封装的低寄生电感(约0.5nH),谐振频率可达数十GHz,适合射频前端;
  • 典型应用场景:
    1. 射频通信:WiFi模块天线匹配、蓝牙信号滤波、5G基站射频链路;
    2. 精密模拟:运算放大器相位补偿、基准电压源去耦、高精度ADC滤波;
    3. 高频振荡:晶体振荡器(XO)、压控振荡器(VCO)负载电容;
    4. 工业控制:温度传感器信号调理、医疗仪器精密测量电路。

五、可靠性与品质保障

TDK作为MLCC头部厂商,该产品通过严苛测试确保长期稳定:

  • 可靠性测试:高温储存(125℃、1000h)、温度循环(-55℃~125℃、1000次)、湿度偏压(85℃、85%RH、50V DC、1000h)均通过;
  • 寿命评估:25℃、额定电压下,平均寿命≥10万小时,满足消费电子、通信设备长期使用;
  • 品质认证:通过ISO 9001、ISO 14001体系认证,产品一致性符合工业级标准。

六、选型与使用注意事项

  1. 降额使用:高温(>85℃)、高湿环境下,建议额定电压降额至70%(35V DC);
  2. 焊接工艺:回流焊峰值温度≤245℃,时间≤10秒,避免过温开裂;
  3. PCB布局:缩短电容与芯片走线距离,减少寄生电感对高频性能的影响;
  4. 存储条件:未开封产品存储于-10℃~40℃、湿度≤60%RH环境,开封后3个月内使用完毕。

该产品凭借C0G介质的高稳定性、小封装的高密度适配性,成为高频精密电路的核心选择,广泛应用于通信、工业、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
