CGA0402X5R475M100GT 贴片陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

CGA0402X5R475M100GT是HRE芯声品牌推出的一款常规容量、中低压、温度稳定型多层贴片陶瓷电容(MLCC),型号编码直接映射核心规格:0402为英制封装尺寸,X5R为温度特性材质,475代表4.7μF容值,M为±20%精度,100对应10V额定电压。该产品定位为小型化电子设备的基础无源器件,覆盖消费电子、物联网、便携穿戴等领域的滤波、耦合、去耦等核心电路需求,兼顾性能稳定与成本可控。

二、关键参数与规格详解

该产品核心参数均符合行业标准,具体如下:

  • 容值与精度:标称容值4.7μF(型号中“475”为容值编码,即47×10⁵pF=4.7μF),精度±20%(“M”为EIA精度代码),满足大多数普通电路对容值偏差的容忍要求;
  • 额定电压:10V直流额定电压(型号中“100”对应10V),适用于低压数字电路、电池供电系统等场景,避免过压击穿风险;
  • 温度特性:采用X5R材质(EIA温度特性分类),工作温度范围为-55℃至+85℃,容值变化≤±15%,相比Y5V等高容但温漂大的材质,更适合对容值稳定性有要求的宽温环境;
  • 封装尺寸:0402英制封装(公制1005,即1.0mm×0.5mm),表面贴装设计,适配高密度PCB布局,助力终端产品小型化;
  • 环保合规:符合RoHS 2.0、无卤素等环保指令,电极及介质材料无铅,兼容主流回流焊/波峰焊工艺。

三、材料与工艺特性

作为MLCC的核心,该产品的材料与工艺直接决定性能可靠性:

  1. X5R陶瓷介质:属于钛酸钡基温度稳定型介质,兼顾容值密度与温漂控制——相比NP0(C0G)材质(温漂极小但容值密度低),X5R能在0402小封装实现4.7μF稳定量产;相比Y5V(容值密度更高但温漂达±20%以上),X5R的温漂控制更优,适合户外、工业等温度变化场景;
  2. 多层叠层工艺:通过数十层陶瓷介质与内部电极交替叠压,经高温烧结形成一体化结构,既提升容值密度,又增强机械稳定性;内部电极采用镍基材料,避免银迁移问题,延长产品寿命;
  3. 表面处理:端电极采用“镍底层+锡镀层”三层结构,兼容回流焊时的润湿性能,焊接后可靠性高,且能抵御环境中的硫化腐蚀。

四、典型应用场景

CGA0402X5R475M100GT因小封装、稳定性能,广泛应用于以下场景:

  • 便携穿戴设备:智能手环、蓝牙耳机的电源滤波(电池输出端去耦)、音频耦合(耳机驱动电路),适配设备小型化需求;
  • 物联网终端:传感器节点、低功耗MCU的电源去耦(如5V以下供电系统)、信号滤波(如无线模块的射频滤波辅助);
  • 消费电子:智能手机/平板的接口电路(USB Type-C滤波、音频接口耦合)、小型家电控制板(遥控器、智能插座的按键电路滤波);
  • 工业小型设备:温度传感器模块、小型PLC的辅助电路(宽温环境下容值稳定)。

五、优势与适用价值

该产品在同规格MLCC中具备以下实用优势:

  1. 小型化适配:0402封装是消费电子最常用的小型封装之一,能显著缩小PCB面积,降低终端产品体积与重量;
  2. 性能稳定可靠:X5R材质的宽温特性,避免低温容值下降、高温容值漂移导致的电路波动,提升设备环境适应性;
  3. 成本效益平衡:常规容量与规格的量产化,使得供应稳定、成本可控,适合批量生产的电子设备;
  4. 工艺兼容性:无铅端电极适配主流SMT产线,回流焊良率高,降低生产端工艺调试成本。

CGA0402X5R475M100GT作为HRE芯声的常规MLCC型号,凭借稳定性能、小封装优势与成本可控性,成为众多小型化电子设备的优选无源器件。

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
