0402X474K500CT 多层陶瓷电容器(MLCC)产品概述

一、产品基本定位与身份标识

华新科(Walsin)推出的0402X474K500CT属于通用型多层陶瓷电容器(MLCC),专为高密度贴片设计的小型化电子设备打造。其型号编码清晰对应核心参数:

  • 「0402」:英制封装规格(对应公制1005);
  • 「X474」:容值编码(47×10⁴ pF = 470nF);
  • 「K」:容值精度±10%;
  • 「500」:额定直流电压50V;
  • 「CT」:华新科封装系列后缀(适配表面贴装工艺)。

该产品定位中低端通用场景,兼顾体积紧凑、成本可控与性能稳定,是电子设备电源滤波、信号耦合的主流选择。

二、核心电气性能参数详解

1. 容值与精度

标称容值470nF(0.47μF),精度±10%,可满足多数电路对容值偏差的容忍度(如滤波电路无需超高精度)。需注意:直流偏置电压会轻微影响容值(X5R材质偏置特性较弱,10V偏置下容值衰减≤5%),实际应用中可通过并联小容值电容补偿。

2. 额定电压

直流额定电压50V,交流应用需降额(交流峰值电压建议不超过35V,避免击穿)。适用于12V、24V等低压系统的电源回路,可覆盖消费电子、工业控制等多数场景。

3. 温度特性

采用X5R陶瓷材质,温度系数定义为:-55℃至+85℃范围内,容值变化≤±15%,远优于普通Y5V材质(±20%),可适应温度波动较大的环境(如车载、户外设备)。

三、封装与物理特性

1. 封装尺寸

0402英制封装(公制1005),具体参数:

  • 长度:1.0mm±0.1mm;
  • 宽度:0.5mm±0.1mm;
  • 高度:≤0.5mm;
    体积仅约0.25mm³,适合智能手机、智能穿戴等小型化设备的高密度贴装。

2. 工艺结构

采用多层陶瓷叠层技术,内部电极以镍(Ni)为主要材料,端电极镀镍-锡合金,符合无铅无卤环保要求(RoHS 2.0、REACH合规),避免对环境和人体造成危害。

3. 焊接适配

支持表面贴装技术(SMT),兼容回流焊、波峰焊:

  • 回流焊:峰值温度235℃±5℃(持续10-30秒);
  • 波峰焊:温度240℃±5℃(持续3-5秒);
    可无缝融入自动化生产流程,降低贴片不良率。

四、稳定性与可靠性表现

1. 温度稳定性

在-55℃至+85℃工作范围内,容值变化稳定在±15%以内,可满足车载电子(-40℃至+85℃)、工业控制等场景的温度需求,避免因温度波动导致电路性能下降。

2. 长期可靠性

经过华新科内部1000小时高温负载测试(125℃、额定电压下),容值衰减≤5%,失效率符合行业标准(MTBF≥10⁹小时);部分批次可满足AEC-Q200汽车级认证,适合对可靠性要求较高的场景。

3. 耐环境性能

封装密封性好,通过IEC 60068-2-67湿热测试(85℃/85%RH下1000小时),可适应湿度变化较大的户外或工业环境,避免因受潮导致绝缘电阻下降。

五、典型应用场景

  1. 消费电子:智能手机电池管理系统(BMS)二次滤波、智能手表音频电路耦合、平板电脑电源模块滤波;
  2. 工业控制:小型PLC输入输出模块、传感器节点电源滤波、电机驱动辅助电路;
  3. 汽车电子:车载USB充电器、仪表盘背光电路、低功率车载娱乐系统滤波(需确认汽车级认证批次);
  4. 通信设备:小型基站射频前端辅助滤波、路由器电源模块滤波。

六、品牌与品质保障

华新科(Walsin)作为全球前五大MLCC制造商之一,拥有30余年被动元器件研发生产经验,产能覆盖中低端通用型至高端汽车级产品。0402X474K500CT通过:

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
