TCC0402X7R822K500AT 贴片电容产品概述

一、产品核心身份与基本参数

TCC0402X7R822K500AT是三环电子(CCTC) 推出的通用型贴片陶瓷电容,型号各段清晰对应核心属性:

  • 「TCC」:三环电子品牌标识;
  • 「0402」:英制封装尺寸(0.04英寸×0.02英寸,公制约1.0mm×0.5mm);
  • 「X7R」:温度系数(-55℃~125℃,容值变化±15%);
  • 「822K」:容值(82×10²pF=8.2nF,K代表±10%精度);
  • 「500」:额定直流电压50V;
  • 「AT」:封装/批次辅助代码。

核心参数平衡了小体积、稳定容值、中耐压,是下游行业的主流选型。

二、关键材质与性能特性

该电容采用X7R陶瓷介质,性能优势显著:

  1. 宽温稳定性:工作温度覆盖-55℃至125℃,容值随温度变化率≤±15%——比Y5V(变化±22%)更稳定,比NP0(高精度但成本高)更具性价比;
  2. 中耐压适配:50V额定电压高于10V/16V等低耐压型号,可覆盖3.3V、5V、12V等常见低压系统,避免过压风险;
  3. 低损耗特性:介质损耗角正切值(tanδ)≤0.02(1kHz下),适合信号耦合、滤波等场景,减少能量损耗。

三、封装规格与物理参数

采用0402小型化封装,厚度仅0.5mm,具备三大适配性:

  • 高密度布局:小体积(1.0mm×0.5mm)适配智能手机、可穿戴设备等紧凑PCB;
  • 轻薄终端兼容:0.5mm薄厚度可用于超薄笔记本、智能手表等轻薄产品;
  • 自动化贴装:封装符合IPC标准,支持回流焊、波峰焊等常规工艺,贴装效率达10k+/小时,适合量产线。

四、典型应用场景

该电容因性能均衡,广泛应用于多领域:

  1. 消费电子:智能手机电源滤波(DC-DC转换电路)、音频信号耦合(耳机接口);
  2. 汽车电子:辅助驾驶雷达信号滤波、车载中控电源模块;
  3. 工业控制:PLC IO接口滤波、小型传感器信号调理;
  4. 医疗电子:便携式监护仪心率信号处理、小型医疗设备稳压。

五、品牌与可靠性保障

三环电子(CCTC)是国内陶瓷电容领域资深厂商,产品可靠性经多重验证:

  • 认证资质:通过RoHS 2.0、REACH环保认证,ISO 9001、IATF 16949(汽车电子)体系认证;
  • 可靠性测试:涵盖高温老化(125℃×1000h)、湿度循环(85℃/85%RH×500h)、机械振动(10-2000Hz×2g),失效率≤0.1%;
  • 市场验证:下游客户覆盖家电、汽车、通信等行业,年出货量超10亿只。

六、选型与使用注意事项

  1. 容值匹配:8.2nF适合10MHz左右中高频滤波,若需更高频率(如射频)建议选1nF以下容值;
  2. 耐压余量:实际工作电压≤35V(额定电压70%),避免长期过压导致容值衰减;
  3. 焊接工艺:回流焊峰值温度240-250℃,时间≤60s,防止介质开裂;
  4. 存储条件:未开封产品存于25℃±5℃、湿度≤60%环境,开封后1年内使用完毕,避免吸潮。

该产品以高性价比、稳定性能成为电子设计中“通用型贴片电容”的优选,适配多场景量产需求。

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
