CGA0805X7R475K350MT 贴片陶瓷电容产品概述

一、核心身份与基本定位

CGA0805X7R475K350MT是HRE芯声品牌推出的多层陶瓷贴片电容(MLCC),属于通用型中低压MLCC范畴。其设计聚焦高密度SMT适配与宽温稳定性,兼顾容值精度、体积效率与成本优势,可覆盖消费电子、工业控制等多领域的滤波、耦合、去耦需求。

二、关键电气性能参数解析

参数项 规格值 核心说明 标称容值 4.7μF 型号后缀“475”对应(47×10⁵pF) 容值精度 ±10%(K档) 满足大部分通用电路精准度需求 额定电压(DC) 35V 工作电压上限,需留1.2~1.5倍余量 温度系数 X7R 宽温稳定特性(-55℃~+125℃) 等效串联电阻(ESR) 典型值<10mΩ(1kHz) 高频损耗低,滤波效率高 等效串联电感(ESL) 典型值<1nH 高频响应快,减少信号衰减

补充:额定电压为直流值,若用于交流电路需按有效值降额至24V以下;±10%精度可避免滤波截止频率偏移,提升电路可靠性。

三、封装与物理特性

采用0805英制贴片封装(尺寸:2.0mm×1.25mm×1.0mm,典型),符合IPC-J-STD-001标准:

  • 无引线设计:适配全自动SMT贴装,生产效率提升30%以上;
  • 陶瓷叠层结构:相比同容值铝电解电容体积缩小90%,适合小型化PCB(如手机、智能穿戴);
  • 端电极镀层:镍-锡双层镀层,兼容回流焊(峰值≤245℃)、波峰焊(温度≤250℃),焊点剪切强度≥10N;
  • 轻量化设计:单颗重量仅0.05g,对便携设备轻量化需求友好。

四、温度稳定性与环境适应性

X7R是MLCC中中温稳定型温度系数,核心优势:

  • 宽温范围:-55℃至+125℃,覆盖工业现场(-40℃+85℃)、车载环境(-40℃+105℃);
  • 容值偏差:全温范围内±15%(远优于Y5V电容的±20%~-82%),避免温度波动导致的性能漂移;
  • 湿度耐受:符合IEC 60068-2-67标准,在90%RH、40℃环境下放置1000h,容值变化≤3%;
  • 振动冲击:可承受10G(10~2000Hz)振动,适合运输设备(如无人机、车载终端)。

五、典型应用场景

  1. 消费电子:手机/平板的DC-DC输出滤波、音频耦合(耳机接口、扬声器驱动);
  2. 工业控制:PLC输入输出模块的去耦电容、传感器信号滤波(抑制电磁干扰);
  3. 通信设备:路由器/交换机的射频干扰滤波、电源模块稳压;
  4. 小型电源:USB-C快充适配器的输出滤波、便携式充电宝的稳压电路;
  5. 汽车电子:车载音响音频耦合、仪表盘背光电源滤波(非汽车级认证,需确认场景)。

六、品牌与质量保障

HRE芯声作为国内MLCC头部厂商,该产品具备:

  • 环保认证:符合RoHS 2.0、REACH SVHC标准,无铅无卤;
  • 可靠性测试:通过高温存储(125℃,1000h)、温度循环(-55℃~+125℃,1000次)、焊接耐热(260℃,10s)等严苛测试;
  • 批量一致性:自动化生产工艺使批次间容值偏差控制在±5%以内(优于标称±10%);
  • 供货稳定:常备库存≥1000万颗,支持小批量样品(100颗起订)与大批量订单交付。

七、选型与使用注意事项

  1. 电压降额:实际工作电压需≤28V(直流),避免过压损坏;
  2. 温度余量:若环境温度接近125℃,建议降额10%使用或切换X8R温度系数;
  3. 焊接规范:回流焊峰值温度≤245℃,时间≤30s;波峰焊温度≤250℃,时间≤5s;
  4. 存储条件:常温干燥环境(25℃±5℃,湿度≤60%RH),存储期≤12个月。

该产品以高性价比、稳定性能成为中低压通用电路的优选MLCC,可满足多数电子设备的小型化、可靠性需求。

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
