TCC00402X7R393K500AT 贴片电容产品概述

TCC0402X7R393K500AT是CCTC(三环) 品牌推出的一款0402封装多层陶瓷贴片电容(MLCC),针对中等容值、宽温环境下的滤波/耦合需求设计,核心参数覆盖39nF容值、±10%精度、50V额定电压及X7R温度系数,广泛适配消费电子、工业控制等多领域高密度PCB布局场景。

一、产品基本信息

  1. 型号与品牌:全称TCC0402X7R393K500AT,由国内老牌被动元件厂商三环电子(CCTC) 研发生产,三环在MLCC领域深耕数十年,产品覆盖中低端到高端应用。
  2. 封装规格:采用0402英制封装(对应公制1005),尺寸为1.0mm×0.5mm×0.5mm(长×宽×厚),是当前小型化电子设备常用的紧凑型封装之一。
  3. 产品类型:属于多层陶瓷贴片电容(MLCC),通过多层陶瓷介质与电极叠层工艺实现高容值密度。

二、核心电气性能参数

参数 具体指标 说明 容值 39nF 标识“393”表示39×10³pF=39nF 精度 ±10% 电容标识“K”代表精度等级 额定电压 50V DC 直流工作电压,交流应用需参考降额曲线(一般降额至额定电压的70%) 温度系数 X7R 工作温度范围-55℃~+125℃,容值变化≤±15%,介电常数εr约2500-3500 损耗角正切 ≤0.002(1kHz) 高频下损耗低,适合信号滤波 绝缘电阻 ≥10⁹Ω·V(25℃) 绝缘性能优异,漏电流极小

三、材料与工艺特性

  1. 陶瓷介质材料:采用X7R铁电陶瓷,介电常数远高于NPO等温度稳定型陶瓷,能在0402小封装内实现39nF中等容值,平衡了容值密度与温度稳定性。
  2. 多层叠层工艺:通过数十层陶瓷介质与镍电极(Ni)交替叠层,大幅提升容值密度,相比单层电容容值提高数倍。
  3. 无铅环保工艺:电极与封装均采用无铅材料,符合欧盟RoHS、REACH指令,无镉、铅等有害物质。
  4. 焊接兼容性:封装引脚采用镀锡工艺,适配回流焊、波峰焊等主流焊接方式,焊点可靠性达行业标准。

四、典型应用场景

  1. 消费电子:智能手机、平板电脑的电源滤波(如电池管理系统)、音频电路耦合(耳机接口、扬声器驱动)。
  2. 工业控制:PLC模块、传感器节点的信号调理电路(如模拟量输入滤波)、低电压电源去耦。
  3. 汽车电子:车载音响、仪表盘背光电源滤波、车身控制模块(BCM)辅助电路(适配-40℃~+85℃车载环境)。
  4. 通信设备:路由器、小型基站的高速信号滤波(如WiFi模块)、电源模块去耦。
  5. 物联网设备:传感器节点、低功耗终端的电源滤波(小体积适配IoT设备紧凑设计)。

五、可靠性与品质保障

  1. 品牌背书:三环电子是国内MLCC领域头部厂商,产品通过ISO 9001质量管理体系认证,批量一致性优于行业平均水平。
  2. 可靠性测试:符合IEC 60384-1标准,通过以下关键测试:
    • 温度循环:-55℃~+125℃循环500次,容值变化≤±10%;
    • 湿度加载:85℃/85%RH环境下1000h,绝缘电阻保持≥10⁸Ω·V;
    • 耐电压测试:50V DC下施加2倍额定电压1分钟,无击穿。
  3. 环保认证:通过RoHS 2.0(2011/65/EU)、REACH(SVHC清单)认证,符合全球环保要求。

六、选型对比优势

  1. 对比电解电容:体积缩小80%以上,无极性,高频损耗低(电解电容高频下容值衰减明显)。
  2. 对比薄膜电容:容值密度高3-5倍(0402封装可实现39nF,薄膜电容同封装仅能做到nF级以下),成本降低约40%。
  3. 对比NPO电容:容值大10倍以上(NPO同封装仅能做到pF级),适合中等容值滤波场景。
  4. 对比Y5V电容:温度稳定性更好(Y5V温度范围-30℃~+85℃,容值变化±20%;X7R覆盖宽温且变化更小)。

整体来看,TCC0402X7R393K500AT凭借紧凑封装、稳定电气性能及宽温特性,成为多领域中等容值滤波/耦合的优选元件,适配高密度PCB设计与恶劣环境应用需求。

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
