TCC0204X5R475K6R3AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心参数

该产品为三环集团(CCTC)生产的0402封装X5R材质MLCC,核心参数如下:

  • 封装规格:英制0402(公制1005),尺寸为1.0mm(长)×0.5mm(宽)×0.5mm(典型厚度),适配高密度PCB布局;
  • 容值与精度:标称容值4.7μF(标识代码“475K”:“475”=47×10⁵pF=4.7μF,“K”代表±10%精度);
  • 电压与温度特性:额定直流电压(DC)6.3V,温度系数X5R(EIA标准),工作温度范围**-55℃~+85℃**,容值随温度变化≤±15%;
  • 其他基础参数:损耗角正切(tanδ)≤2.5%(1kHz、25℃测试),额定纹波电流需参考官方 datasheet(适配低压小电流场景);
  • 环保合规:无铅化设计,符合RoHS 2.0、REACH SVHC清单要求。

二、关键特性解析

  1. 温度稳定性适配主流场景:X5R材质平衡了容值密度与温度稳定性——相比Y5V(温度变化±22%)更可靠,适合环境温度波动较大的消费电子(如手机、穿戴设备);
  2. 小封装高密度集成:0402封装体积仅为传统1206封装的1/16,可显著缩小PCB面积,满足便携设备“轻薄化”设计需求;
  3. 低压场景高可靠性:6.3V额定电压针对低压数字电路优化,避免过压风险;三环多层陶瓷叠层工艺确保低ESR(等效串联电阻)、低ESL(等效串联电感),提升滤波/耦合效率;
  4. 焊接兼容性强:回流焊温度范围(180℃~220℃)适配常规SMT流程,焊接不良率≤0.1%(官方测试数据)。

三、典型应用场景

该电容主要针对低压便携电子设备的信号处理与电源管理,典型应用包括:

  • 智能手机/平板:CPU内核供电去耦、射频前端电路滤波、音频信号耦合;
  • 智能穿戴:手环/手表传感器供电滤波、蓝牙模块信号耦合、低功耗MCU电源去耦;
  • 小型消费电子:蓝牙耳机充电电路滤波、TWS耳机射频匹配、便携式蓝牙音箱音频滤波;
  • 工业低压模块:小型PLC I/O口滤波、低功耗传感器节点电源稳压辅助滤波(工作电压≤5V)。

四、可靠性与品质保障

三环作为国内MLCC龙头,该产品通过多项行业标准测试:

  • 高温负载寿命(HTOL):85℃、6.3V直流下工作1000小时,容值变化≤±10%,损耗角正切变化≤±20%;
  • 温度循环测试:-55℃~+85℃循环1000次,无封装开裂、容值漂移符合规格;
  • 机械可靠性:PCB弯折角度≥5°时,无电容脱落、性能无衰减;
  • 合规认证:具备RoHS 2.0、REACH证书,部分批次可提供汽车级AEC-Q200认证(需确认具体型号)。

五、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即≤5V),避免长期过压导致容值衰减;
  2. 温度适配:若设备工作环境长期高于85℃,需替换为X7R材质(-55℃~+125℃);
  3. 封装焊接:0402焊盘需遵循IPC标准(建议尺寸0.6mm×0.3mm),避免焊盘过大导致桥连、过小导致虚焊;
  4. 并联扩容:如需更大容值,可并联多个同规格电容(并联后ESR降低、ESL叠加),需根据电路需求调整数量。

该产品凭借小体积、高可靠性与成本优势,成为消费电子领域低压滤波/耦合的主流选型之一。

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
