TDK CGA2B2X5R1C473KT0Y0F 多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与定位

CGA2B2X5R1C473KT0Y0F是TDK公司推出的通用型多层陶瓷贴片电容(MLCC),属于CGA系列产品线。该产品针对中低压、常规温度环境下的电子电路设计,主打小型化、稳定可靠与成本效益,广泛适配消费电子、小型家电及工业辅助电路等场景,是主流电子设备中常见的基础无源元件之一。

二、关键性能参数解析

产品核心参数直接对应电路设计的核心需求,各参数的技术意义如下:

  1. 容值与精度:标称容值47nF(3位编码规则:前两位“47”为有效数字,第三位“3”表示10³倍,即47×10³pF=47nF),精度±10%(参数后缀“K”标识),满足常规电路对容值偏差的容忍需求,无需额外校准;
  2. 额定电压:16V(型号中“1C”标识对应16V额定值),适用于直流/交流中低压电路(交流工作时需注意峰值电压不超过16V,即有效值≤11.3V),避免电击穿风险;
  3. 温度系数:X5R(型号中“X5R”明确标识),符合IEC标准的温度特性——工作温度范围-55℃~+85℃,容值变化≤±15%,兼顾温度适应性与容值稳定性,优于Y5V类电容的温度特性;
  4. 封装标识:0402(英制封装,对应公制1005),是小型化贴片封装的典型代表,适配高密度PCB设计。

三、封装与物理特性

该产品采用0402贴片封装,物理尺寸符合行业标准,具体参数(典型值)如下:

  • 长度:1.0±0.2mm;
  • 宽度:0.5±0.2mm;
  • 厚度:0.5±0.1mm;
  • 端电极:镍/锡镀层(Ni/Sn),兼容主流表面贴装工艺(回流焊、激光焊等),焊接后机械强度可靠,可承受常规PCB弯曲应力(0.5mm以内无断裂);
  • 小型化优势:0402封装体积仅为0805封装的1/4左右,大幅提升PCB布局密度,适配手持设备、小型模块等对空间要求严格的场景。

四、温度特性与可靠性

4.1 温度适应性

X5R温度系数是该产品的核心特性之一,具体表现为:

  • 低温端(-55℃):容值变化≤+15%;
  • 高温端(+85℃):容值变化≤-15%;
  • 温度循环稳定性:经过-55℃~+85℃循环测试(典型1000次),容值与绝缘电阻无显著衰减,满足常规电子设备的环境适应性需求。

4.2 可靠性指标

TDK MLCC产品通常符合JIS C 5102、IEC 60384-14等国际标准,关键可靠性指标包括:

  • 绝缘电阻:25℃下≥10⁹Ω·μF(典型值);
  • 耐湿性:经85℃/85%RH环境测试(1000h),性能无明显下降;
  • 耐电压:额定电压下连续工作1000h,无击穿或容值衰减超标的情况。

五、典型应用场景

CGA2B2X5R1C473KT0Y0F的参数特性决定了其适用于以下场景:

  1. 消费电子:手机、平板、智能手环等设备的电源滤波(滤除DC-DC转换产生的高频噪声)、信号耦合(隔直流传交流,如音频信号路径)、旁路电容(给高频信号提供低阻抗回路);
  2. 小型家电:遥控器、智能插座、小型打印机的控制电路,满足低电压、小空间的设计需求;
  3. 工业辅助电路:PLC(可编程逻辑控制器)的辅助电源模块、传感器接口电路,适配-20℃~+60℃的工业环境;
  4. 汽车电子(非关键):若产品符合AEC-Q200标准(需参考官方认证),可用于车载娱乐系统、仪表盘的低压电路(需注意工作温度范围是否覆盖车载环境)。

六、产品优势与市场价值

与同类型产品相比,该产品的核心优势体现在:

  1. 品牌可靠性:TDK作为全球MLCC龙头企业,产品一致性好,批量供货稳定,降低电路设计的良率风险;
  2. 温度-容值平衡:X5R系数兼顾温度适应性与容值稳定性,比NPO类电容容值范围广,比Y5V类电容温度范围宽,适配更多常规场景;
  3. 成本效益:通用型MLCC定位,单价合理,适合大规模量产应用;
  4. 小型化适配:0402封装满足当前电子设备“轻薄化”趋势,提升PCB集成度。

该产品是中低压常规电路的高性价比选择,可有效满足电子设备对滤波、耦合、旁路等功能的基础需求。

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.
