CGA0201X7R472K500ET 多层陶瓷电容器产品概述

一、产品基本信息与型号解析

CGA0201X7R472K500ET是HRE芯声电子推出的微型多层陶瓷电容器(MLCC),型号字符对应明确技术定义:

  • CGA:MLCC通用前缀,标识产品类型;
  • 0201:英制封装(0.02英寸×0.01英寸),对应公制尺寸约0.6mm×0.3mm,为小型化设备主流微型封装;
  • X7R:温度系数代码,代表宽温特性范围;
  • 472:容值编码(47×10²=4700pF=4.7nF);
  • K:容值精度±10%;
  • 500:直流额定电压50V;
  • ET:HRE内部规格码,关联端电极结构、镀层细节。

二、核心电气性能参数详解

  1. 容值与精度:标称4.7nF,精度±10%,满足多数滤波、耦合场景的常规精度需求;
  2. 额定电压:直流50V,建议实际工作电压≤40V(降额20%),避免电压应力导致性能衰减;
  3. 介电特性:X7R铁电陶瓷介质,介电常数2000~4000,平衡小型化与高容值(优于NP0的稳定性但容值更高);
  4. 损耗角正切:典型值≤1%(1kHz/25℃),高频损耗低,适合信号通路与电源滤波。

三、封装与物理特性说明

HRE官方规格中,0201封装物理参数为:

  • 尺寸:0.60±0.03mm(长)×0.30±0.03mm(宽)×0.30±0.03mm(厚);
  • 端电极:三层结构(Ni底层+Cu中间层+纯Sn表层),符合RoHS 2.0无铅要求;
  • 重量:约0.001g,无磁性,适配智能穿戴、射频模块等敏感场景。

四、温度特性与稳定性分析

X7R温度系数定义为:-55℃~+125℃内,容值变化率≤±15%,宽温稳定性显著优于Y5V(±22%),适合汽车电子、工业控制等环境;需注意:若需极高精度(±5%内),需替换为NP0介质(容值变化≤±30ppm/℃)。

此外,X7R电压依赖性低,额定电压内容值变化≤5%,适配直流/低频交流电路。

五、典型应用场景

  1. 小型消费电子:智能手机、智能手表的电源滤波(电池管理)、信号耦合(蓝牙/音频);
  2. 汽车电子:车载仪表盘、导航系统的辅助电路(宽温耐受);
  3. 工业控制:PLC模块、传感器节点的旁路电容(工业环境稳定);
  4. 物联网设备:低功耗IoT终端(智能门锁)的电源管理(微型化需求);
  5. 通信设备:小型基站、路由器的信号处理(低损耗保障质量)。

六、品牌与可靠性优势

HRE芯声的该产品具备:

  1. 工艺可靠:流延成型+叠层印刷工艺,端电极附着力≥1N,耐260℃回流焊3次无开裂;
  2. 认证齐全:符合AEC-Q200(汽车级)、IPC-A-610(组装)标准,批量一致性高;
  3. 环保合规:无铅无卤,满足RoHS 2.0、REACH,适配出口产品;
  4. 供应稳定:年产能充足,交货周期短,支持中小批量至大规模采购。

七、选型与使用注意事项

  1. 电压降额:实际电压≤40V,避免过压击穿;
  2. 温度适配:超125℃需换X8R(-55℃~+150℃);
  3. 焊接工艺:优先回流焊(240~260℃,≤30s),避免波峰焊(易开裂);
  4. 存储条件:常温干燥(≤30℃,≤60%湿度),开封1个月内用完(防受潮popcorning);
  5. 精度匹配:需±5%精度则换J档,但X7R无J档,需选NP0介质。

该产品凭借小型化、宽温稳定、高可靠性,成为消费电子、汽车电子等领域的主流选型之一。

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
