    • 0402:封装代码(英制)
    • COG:温度系数(EIA标准,对应IEC的NP0类)
    • 8R2:容值标识(8.2pF,“R”代表小数点)
    • C500:额定电压(50V DC,“C”代表电压等级,500为50V×10)
    • AT:工艺后缀(无铅环保,可焊性优化,适配回流焊工艺)

二、关键性能参数详解

该产品核心参数围绕高频稳定性、低损耗、宽温特性设计,具体如下:

  1. 容值与精度:标称容值8.2pF,精度±0.25pF(C0G介质典型精度,满足精密电路谐振、滤波需求)
  2. 额定电压:50V DC(直流额定电压,交流应用需按频率降额,如1MHz下降额至25V)
  3. 温度系数:COG(±30ppm/℃,-55℃~+125℃范围内容值变化≤±0.3%),无容值漂移问题
  4. 损耗角正切:≤0.15%(1kHz、25℃测试条件,低损耗适合射频信号传输,减少信号衰减)
  5. 等效参数:ESR(等效串联电阻)≤1Ω(100MHz),ESL(等效串联电感)≤0.5nH(典型值),适配高速电路快速充放电
  6. 工作温度范围:-55℃~+125℃(工业级宽温,适应极端环境如汽车、户外设备)

三、核心材料与结构特性

TCC0204COG8R2C500AT采用成熟的MLCC结构设计,材料选择兼顾性能与可靠性:

  1. 介质材料:C0G型低温烧结陶瓷(钛酸锶基),具有无极性、温度稳定性极佳、损耗极低的特点,避免了X7R等介质的容值随温度/电压漂移问题
  2. 内电极:镍(Ni)电极,环保无铅,与介质兼容性好,多层叠层设计实现小体积下的稳定容值
  3. 外电极:三层结构(镍层+纯锡层),可焊性符合IPC J-STD-002标准,焊接后附着力强,抗机械应力(如振动、冲击)
  4. 结构优势:多层叠层设计降低了等效串联参数,同时优化了热传导,避免局部过热导致的性能衰减

四、典型应用场景

因C0G介质的高频低损耗与温度稳定性,该产品主要应用于以下领域:

  1. 射频通信设备:5G基站、Wi-Fi 6/7路由器、蓝牙5.3模块的滤波器、耦合器、VCO(压控振荡器)电路(需稳定的谐振频率)
  2. 高速数字电路:服务器、交换机的时钟电路、高频去耦(抑制100MHz以上的共模/差模噪声)
  3. 医疗电子:便携式血糖仪、心电监护仪的信号调理电路(需高精度、无漂移的电容参数)
  4. 汽车电子:车载导航、ADAS系统的射频接收电路(宽温特性适应-40℃~+85℃的汽车环境)
  5. 消费电子:智能手机、智能手表的射频前端(0402封装适配轻薄化设计)

五、可靠性与环境适应性

三环电子对该产品进行了严格的可靠性测试,满足工业级与消费级应用的要求:

  1. 温度循环测试:-55℃~+125℃循环500次,容值变化≤±1%,无开裂、短路、开路
  2. 湿度负载测试:85℃/85%RH、50V DC下1000h,损耗变化≤±10%,无失效
  3. 机械性能:振动(10~2000Hz,20g加速度)、冲击(1000g,0.5ms)测试后性能稳定
  4. 环保认证:符合RoHS 2.0、REACH指令,无铅无镉,满足绿色制造要求

六、选型与使用注意事项

为保证产品性能与寿命,使用时需注意以下几点:

  1. 电压降额:实际工作电压不超过额定电压的80%(直流),交流应用需按频率降额(如1MHz下降额至50%)
  2. 焊接工艺:采用回流焊(温度曲线:预热150180℃,峰值230250℃,时间≤30s),避免波峰焊(易导致0402小封装电容脱落)
  3. 静电防护:MLCC易受静电损坏(静电电压≥100V即可击穿),操作时需佩戴防静电手环,使用防静电工作台与包装
  4. 储存条件:室温25℃、湿度≤60%,未开封产品储存时间不超过12个月,开封后尽快使用(建议1个月内用完)
  5. 极性区分:C0G介质为无极性电容,无需区分正负极,安装时可任意方向贴装

该产品凭借超小体积、高稳定性、低损耗的特点,成为高频精密电路的理想选择,三环电子的成熟工艺也保证了批量供应的一致性与可靠性,可满足客户多样化的设计需求。

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
