CGA0402X5R474K500GT多层陶瓷电容器产品概述

一、产品基本定位与型号解析

CGA0402X5R474K500GT是国内电子元器件品牌HRE芯声推出的一款0402封装多层陶瓷电容器(MLCC),核心面向小型化、中等电压需求的电子设备设计。其型号命名遵循行业通用规则,各部分含义清晰:

  • CGA:陶瓷电容器产品前缀(明确为MLCC类型);
  • 0402:英制封装尺寸(对应公制1005,即长1.0mm×宽0.5mm);
  • X5R:温度系数与容值变化特性(核心材料属性);
  • 474:容值编码(47×10⁴ pF = 470nF);
  • K:容值精度(±10%);
  • 500:额定直流电压(50V);
  • GT:产品系列后缀(代表常规商用级规格,适配多数民用/工业场景)。

二、核心性能参数与实际价值

该产品的关键参数针对中等复杂度电路需求优化,具体价值如下:

1. 容值与精度

容值为470nF(0.47μF),精度±10%(K级),既避免容值过小导致滤波效果不足,也通过±10%精度控制降低电路匹配难度——可直接用于电源滤波、信号耦合等基础电路,无需额外匹配补偿。

2. 额定电压

额定直流电压为50V,适用于中等电压场景(如12V/24V系统二次滤波、小型电源模块储能)。按行业1.5倍降额规则,实际可覆盖33V以下工作电压,适配多数消费电子、工业设备的电压范围,同时避免过压击穿风险。

3. 封装与尺寸

0402(1005)封装体积仅为1.0mm×0.5mm×0.5mm(典型值),是小型化设备的核心适配方案:可显著减少PCB占用面积(比0603封装节省60%以上空间),适合智能手机、可穿戴设备、小型通信模块等对空间敏感的应用。

三、X5R温度特性的应用优势

X5R是该产品的核心材料特性,其定义为:工作温度范围-55℃~+85℃,容值变化±15%,在MLCC材料中属于“平衡型”特性,相比其他常见温度系数有明显优势:

  • 对比NPO(COG):NPO容值变化仅±0.3%,但容值上限通常低于100nF,无法满足470nF的需求;
  • 对比Y5V:Y5V容值可达μF级,但容值变化±20%以上,且温度范围窄(仅-30℃~+85℃),不适合宽温场景;
  • X5R的平衡优势:既保证470nF的实用容值,又能在-55℃~+85℃宽温范围内稳定工作,适配户外设备、工业控制等对温度敏感的场景。

四、封装工艺与可靠性保障

HRE芯声针对该产品采用成熟的MLCC生产工艺,确保长期可靠性:

  1. 叠层工艺:采用高精度叠层技术,电极层数与陶瓷层厚度严格匹配,避免短路/开路风险;
  2. 端电极设计:端电极采用“镍底层+锡镀层”结构,附着力强,可耐受260℃焊接温度(符合IPC J-STD-001标准),且通过RoHS 2.0环保认证(无铅、无镉);
  3. 可靠性测试:产品通过高温存储(125℃×1000h)、温度循环(-55℃~+85℃×1000次)、湿度负荷(85℃/85%RH×1000h)等行业标准测试,失效率低于100 FIT(每10亿小时故障数)。

五、典型应用场景

该产品因体积小、容值适中、温变稳定,广泛应用于以下领域:

  1. 消费电子:智能手机/平板电脑的电源滤波(如充电电路、基带芯片去耦)、可穿戴设备的传感器信号耦合;
  2. 工业控制:小型PLC(可编程逻辑控制器)的输入输出电路滤波、工业传感器的信号调理;
  3. 通信设备:小型基站(小站)的射频模块去耦、路由器/交换机的电源滤波;
  4. 汽车电子:车载信息娱乐系统(非动力系统)的音频耦合、仪表盘背光电路滤波(温度范围适配车载环境)。

六、品牌与质量支持

HRE芯声作为国内专注MLCC研发生产的厂商,拥有10余年行业经验,产品线覆盖02011206封装、1pF100μF容值,产品通过ISO9001质量体系认证,部分规格符合IATF16949汽车电子标准。针对该产品,HRE提供:

  • 样品快速交付(1~3工作日);
  • 技术支持(电路匹配建议、降额设计指导);
  • 批量订单保障(月产能可达百万级,适配中小批量需求)。

该产品以“小体积+实用容值+宽温稳定”为核心优势,是消费电子、工业控制等领域小型化电路设计的高性价比选择。

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.
