HRE CGA0201X7R102K500ET 多层陶瓷电容产品概述

HRE(芯声)推出的CGA0201X7R102K500ET是一款小型化多层陶瓷电容(MLCC),针对中低压宽温场景下的信号滤波、耦合及去耦需求设计,凭借紧凑封装、稳定温度特性与高可靠性,成为消费电子、工业控制等领域的常用选型之一。

一、产品基本信息

该产品属于HRE CGA系列MLCC,采用0201英制贴片封装(对应公制0.6mm×0.3mm),介质类型为X7R陶瓷,核心参数围绕容值、电压、精度形成明确定位:

  • 容值:1nF(型号中“102”表示10×10²pF)
  • 精度:±10%(型号中“K”为精度代码)
  • 额定电压:50V直流(型号中“500”对应50V)
  • 温度范围:-55℃~+125℃(X7R介质典型宽温特性)

产品符合RoHS 2.0、REACH等环保法规,端电极采用Ni/Sn无铅镀层,适配标准回流焊工艺。

二、核心参数解析

1. 容值与精度

容值1nF(1000pF)为中高频滤波常用规格,±10%的精度满足大部分通用场景(如电源滤波、信号耦合),若需更高精度(如振荡器匹配)需切换至NPO(COG)介质产品。

2. 电压特性

额定50V为直流连续工作电压,需注意陶瓷电容的电压降额规则:

  • 交流峰峰值电压建议不超过35V(降额系数≈0.7);
  • 脉冲电压峰值不超过50V,避免介质击穿。

3. 温度与损耗

X7R介质在-55℃~+125℃范围内,容值变化≤±15%,介质损耗(tanδ)≤2%(1kHz、25℃下),绝缘电阻(IR)≥10⁶ MΩ·μF(25℃、10V直流下),兼顾宽温稳定性与高频损耗控制。

三、封装与可靠性验证

1. 0201封装细节

封装尺寸为长0.60±0.05mm×宽0.30±0.05mm×厚0.30±0.05mm,端电极长度0.15±0.05mm、宽度0.30±0.05mm,适配高密度PCB设计(如智能手机主板、小型通信模块)。

2. 可靠性测试

HRE对该产品完成多项行业标准验证:

  • 高温存储:125℃/1000h,容值变化≤±5%;
  • 温度循环:-55℃~+125℃/1000次循环,无开路/短路;
  • 湿度测试:85℃/85%RH/1000h,绝缘电阻衰减≤20%;
  • 焊接可靠性:符合J-STD-020回流焊规范,焊点附着力≥10N(0201封装典型值)。

四、典型应用场景

该产品因小型化、宽温稳定特性,广泛应用于以下领域:

  1. 消费电子:智能手机CPU供电滤波(并联大容值电解电容实现宽频滤波)、蓝牙/WiFi模块信号耦合、耳机接口静电防护;
  2. 工业控制:PLC输入输出电路滤波、变频器控制板去耦、传感器信号调理;
  3. 通信设备:基站射频单元去耦、路由器电源模块滤波、光模块信号耦合;
  4. 汽车电子(非车载级):车载信息娱乐系统(如导航、音响)的信号滤波(若需AEC-Q200认证需切换HRE对应车规系列)。

五、选型与应用注意事项

  1. 电压降额:交流或脉冲场景必须降额,避免介质极化饱和导致容值下降或击穿;
  2. 温度范围:超出-55℃~+125℃时,容值变化会超过±15%,不建议使用;
  3. 焊接工艺:需按HRE规范设置回流焊曲线(预热150-180℃、峰值240-250℃、时间≤30s),避免过温开裂;
  4. 并联设计:高频滤波场景可并联多个小容值MLCC,覆盖不同频率段(如1nF+10nF并联实现10kHz~100MHz滤波)。

该产品凭借平衡的性能与成本优势,成为通用电子设计中替代传统电解电容的理想选型,适配各类小型化、宽温应用需求。

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
