CGA0805X5R476M100MT 多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与定位

CGA0805X5R476M100MT是HRE(芯声)品牌推出的通用型多层陶瓷贴片电容(MLCC),聚焦低电压中容值场景,型号各部分清晰传递核心属性:

  • CGA:MLCC通用前缀标识;
  • 0805:英制封装尺寸(对应公制2.0mm×1.2mm),贴片电容主流封装之一;
  • X5R:温度系数代码,定义容值随温度变化的特性;
  • 476:容值编码(47×10⁶pF=47μF);
  • M:精度代码(±20%);
  • 100:额定直流电压10V;
  • MT:封装细节/批次关联标识。

该产品定位为消费电子、小型智能设备的电源滤波、旁路核心元件,兼顾体积紧凑性与性能稳定性。

二、关键性能参数全解析

  1. 容值与精度
    标称容值47μF,精度±20%(M代码)。此精度等级平衡了滤波效果与成本,适合对容值一致性要求不苛刻的场景(无需高精度的日常电路)。

  2. 额定电压
    直流额定电压10V,可耐受短时间1.5倍过压,适配3.3V、5V等主流低电压电路,尤其适合便携式设备的电源系统。

  3. 封装尺寸
    标准0805封装(公制:长2.0±0.15mm,宽1.27±0.15mm,厚0.85±0.05mm),体积小巧,支持高密度PCB贴装,适配自动化生产。

  4. 温度特性
    工作温度范围-55℃~+85℃,容值变化±15%(相对于25℃基准值),满足常规环境的温度波动需求。

三、封装结构与工艺特点

采用多层陶瓷叠层结构,核心工艺适配中容值与小体积需求:

  • 介质层:X5R特性陶瓷材料,介电常数(ε)约2000~4000,平衡容值与体积;
  • 电极层:内外电极采用镍基材料,表面镀无铅锡(符合RoHS标准),焊接兼容性好(适配回流焊、波峰焊);
  • 叠层设计:多层介质与电极交替叠压,实现47μF容值与0805封装的结合;
  • 无极性设计:陶瓷封装无正负极,贴装效率高,抗机械应力能力优于电解电容。

四、温度特性与环境适应性

X5R是MLCC通用型温度系数的典型代表,对比其他系数的优势:

  • 比Y5V(-30℃~+85℃,容值变化+22%/-82%)稳定性更高,适配温度波动较大的场景(如户外设备);
  • 比NPO(-55℃~+125℃,容值变化±0ppm)成本更低,无需高精度容值的场景下性价比突出。

该产品可适应室内外、高低温交替环境(如智能手表户外使用、小型家电常温环境),容值波动在可接受范围内,不影响滤波效果。

五、典型应用场景梳理

结合参数与特性,核心应用场景包括:

  1. 消费电子终端:手机、平板、智能手表的电源滤波(DC-DC输出端、电池管理系统旁路)、音频电路耦合;
  2. 便携式智能设备:蓝牙耳机、智能音箱、移动电源的低电压电源滤波,利用0805封装适配紧凑空间;
  3. IoT模块:智能门锁、温湿度传感器、小型路由器的电源去耦,满足低功耗、小体积设计;
  4. 工业辅助电路:小型PLC模块、传感器节点的信号滤波,抗振动特性适配工业环境。

六、可靠性与品牌保障

HRE(芯声)作为国内MLCC专业制造商,该产品具备可靠保障:

  • 环保合规:符合RoHS 2.0、REACH标准,无铅无镉,适配全球市场;
  • 可靠性测试:通过高温存储(125℃/1000h)、温度循环(-55℃~+85℃/500次)等行业测试,确保长期稳定;
  • 批量一致性:自动化生产工艺保障参数一致,适合电子设备批量生产,降低BOM成本。

总结

CGA0805X5R476M100MT是一款高性价比通用MLCC,以0805小封装实现47μF中容值,兼顾温度稳定性与环境适应性,广泛适配消费电子、IoT等低电压场景,是小型化电子设备的理想滤波元件。

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
