0402X474K6R3CT 陶瓷电容器产品概述

0402X474K6R3CT是华新科(Walsin)推出的一款多层陶瓷电容器(MLCC),针对小型化电子设备的滤波、耦合等需求设计,凭借紧凑封装与稳定的温度特性,在消费电子、通信等领域广泛应用。

一、产品基本属性与型号解析

该产品隶属于华新科常规MLCC产品线,型号命名遵循行业通用规则:

  • 0402:英制封装代码,对应公制尺寸1005(长1.0mm×宽0.5mm),适配高密度表面贴装工艺;
  • X474:容值标识,“474”表示47×10⁴pF=470nF=0.47μF;
  • K:精度等级,代表容值偏差为±10%;
  • 6R3:额定直流电压,即6.3V;
  • CT:系列/包装辅助标识,通常对应无铅电极或特定包装规格。

产品采用多层陶瓷叠层结构,属于X5R介质类型的片式电容器,无极性设计便于电路集成。

二、核心技术参数详解

  1. 容值与精度:标称容值470nF(0.47μF),精度±10%(K档),满足多数常规电路对容值的需求;
  2. 额定电压:直流6.3V,需注意实际工作电压建议降额至额定值的80%(≤5V),避免过压失效;
  3. 温度特性:X5R介质的温度范围为-55℃~+85℃,在此区间内容值变化≤±15%,比Y5V等低阶介质稳定性更优;
  4. 封装尺寸:0402英制(1005公制),典型厚度0.5±0.1mm,重量约0.001g,适配小型化设备的贴装密度;
  5. 损耗与耐电压:损耗角正切(tanδ)≤1%(1kHz/25℃),耐电压性能为额定电压的1.5倍(9.45V)持续1分钟,可靠性符合行业标准。

三、材料与结构特点

该产品采用钛酸钡基陶瓷介质(X5R类型),通过多层叠层工艺将陶瓷介质与镍内电极交替堆叠,经高温烧结形成一体化结构:

  • 介质材料:X5R陶瓷的介电常数较高(约2000~3000),相同封装下可实现比NP0介质更大的容值;
  • 电极设计:内电极为镍(Ni),外电极采用无铅锡银铜(Sn-Ag-Cu)或锡铅合金,符合RoHS环保要求;
  • 结构优势:多层叠层增加了有效电极面积,在小封装内实现高容值密度,同时避免了电解液(对比电解电容),提升了耐振动、耐冲击性能。

四、典型应用场景

0402X474K6R3CT的小体积与稳定特性,使其适用于以下场景:

  1. 消费电子:智能手机、平板电脑的电源滤波(如CPU供电回路的去耦)、音频电路耦合;
  2. 便携式设备:智能手表、无线耳机的信号滤波(蓝牙/WiFi模块)、电池管理系统辅助电路;
  3. 通信模块:路由器、物联网节点的射频滤波与电源稳压;
  4. 汽车电子:车载显示屏、车载音响的低压辅助电路(需确认工作温度不超过85℃);
  5. 工业控制:小型传感器模块的信号滤波、微控制器外围电路。

五、性能优势与选型价值

  1. 小型化适配:0402封装满足设备轻薄化趋势,可提升电路板贴装密度;
  2. 温度稳定性:X5R介质的容值变化远小于Y5V,适合对容值稳定性有要求的电路(如滤波、振荡回路);
  3. 可靠性突出:无电解液、无极性,耐振动(10~2000Hz,加速度1.5g)、耐冲击(1000g/0.5ms)性能优于电解电容;
  4. 性价比适中:比NP0介质成本低,比小容值电解电容更适合小封装,平衡了性能与成本;
  5. 环保合规:无铅电极设计符合RoHS、REACH等环保标准,适配出口产品需求。

六、使用注意事项

  1. 电压降额:实际工作电压需低于额定值的80%,避免过压导致介质击穿;
  2. 温度范围:使用环境温度需控制在-55℃~+85℃内,超出范围会导致容值变化超出规格;
  3. 贴装工艺:0402封装需注意贴装精度(建议±0.1mm),回流焊峰值温度控制在245±5℃,时间不超过10秒;
  4. 静电防护:陶瓷电容对静电敏感,存储与贴装需采用防静电包装与设备;
  5. 容值验证:批量使用前建议抽样测试容值、损耗等参数,确保符合电路设计要求。

综上,0402X474K6R3CT凭借小体积、稳定温度特性与高可靠性,成为小型化电子设备中滤波、耦合电路的常用选型之一。

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.
