CGA0402X7R823K250GT多层陶瓷电容(MLCC)产品概述

一、产品型号解析与基本定位

该产品为HRE芯声品牌通用型多层陶瓷电容,型号各字符对应核心信息:

  • CGA:HRE芯声MLCC系列封装标识;
  • 0402:英制封装尺寸(对应公制1005,即1.0mm×0.5mm);
  • X7R:温度系数代码(-55℃~+125℃范围内容值稳定);
  • 823:容值编码(82×10³pF=82nF);
  • K:精度等级(±10%);
  • 250:额定电压(25V DC);
  • GT:生产工艺/批次辅助标识。

产品主打小型化、宽温稳定、高可靠性,适配中低压电路的滤波、耦合、去耦等核心需求。

二、核心性能参数详解

参数项 具体指标 说明 标称容值 82nF(823) 标准电容值 精度等级 ±10%(K级) 满足多数电子电路容值偏差要求 额定电压 25V DC 低至中压电路安全工作电压 温度系数 X7R 工作温度-55℃~+125℃,容值漂移≤±15% 损耗角正切(tanδ) ≤0.015(1kHz时) 低损耗减少电路功耗 频率响应 1MHz以下稳定 适配电源滤波、信号耦合等低频场景

三、封装与物理特性

采用0402表面贴装封装(SMT),物理参数符合行业标准:

  • 尺寸:长度1.0±0.1mm,宽度0.5±0.1mm,厚度0.5±0.1mm;
  • 电极:两端银/镍电极,表面镀锡(Sn),兼容常规SMT贴片机;
  • 工艺适配:支持回流焊(峰值温度260±5℃,时间≤10s)、波峰焊(需特殊防护);
  • 环保认证:符合RoHS 2.0、REACH法规,无铅无镉。

四、X7R陶瓷材料的核心优势

X7R是MLCC中温度稳定性与性价比平衡最优的材料,相比经济型Y5V、高频NP0材料:

  1. 宽温覆盖:-55℃~+125℃,可应对工业、车载(非高压)等宽温场景;
  2. 容值稳定:温度变化时容值漂移≤±15%,避免电路性能随温度波动;
  3. 尺寸适配:0402小封装下实现82nF容值,兼顾小型化与容值需求,无需牺牲尺寸换容量。

五、典型应用场景

该产品因小封装、宽温稳定、25V电压适配性,广泛应用于:

  1. 消费电子:智能手机、智能手表的电源滤波(电池供电去耦)、音频信号耦合(耳机/扬声器电路);
  2. 工业控制:小型PLC模块、传感器节点(温度/压力传感器)的信号滤波,应对-20℃~+85℃工业环境;
  3. 通信设备:路由器、交换机的100MHz以下高频滤波、电源模块去耦,提升信号纯度;
  4. 医疗电子:家用血糖仪、血压计的电源电路,依赖X7R稳定性能保证测量精度;
  5. 车载电子:中控屏、音响的辅助电路(非高压部分),适配车载-40℃~+85℃环境。

六、可靠性与环境适应性

HRE芯声对该产品通过严格可靠性测试,符合行业标准:

  • 耐温测试:回流焊260℃循环10次,无开裂、容值漂移;
  • 振动测试:10~2000Hz振动(加速度10g),无引脚脱落、性能失效;
  • 湿热测试:85℃/85%RH环境1000h,容值变化≤±5%;
  • 寿命测试:25V/125℃下工作1000h,容值变化≤±10%,满足工业级寿命要求。

七、品牌与品质保障

HRE(芯声)是国内专注MLCC研发生产的企业,具备10余年制造经验:

  • 质量体系:通过ISO 9001、ISO 14001认证;
  • 定制支持:批量订单可定制精度(如±5%)、电压(如50V);
  • 售后保障:提供1年质保,技术团队支持电路设计选型。

该产品以高性价比、稳定性能成为中小功率电子设备的理想电容选择,覆盖消费、工业、通信等多领域需求。

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
