CGA0402X7R102K500GT 多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与定位

CGA0402X7R102K500GT是HRE芯声推出的通用型多层陶瓷贴片电容(MLCC),型号各段代码明确映射产品核心属性:

  • CGA:封装标识(代表小型化多层陶瓷结构);
  • 0402:英制封装尺寸(对应公制1005,即1.0mm×0.5mm);
  • X7R:介质类型(宽温稳定型);
  • 102:标称容值(1nF,即10×10²pF);
  • K:容值精度(±10%,EIA标准精度等级);
  • 500:额定电压(50V DC,直流工作上限);
  • GT:品牌定制后缀(代表工业级标准)。

该产品定位为通用宽温型MLCC,兼顾小型化、稳定性与成本优势,适用于多数电子设备的电源滤波、信号耦合场景。

二、关键性能参数解析

参数项 具体规格 核心说明 标称容值 1nF(102pF) 多层陶瓷叠层工艺实现的稳定容值 容值精度 ±10%(K档) 满足90%以上通用电子场景的精度需求 额定电压 50V DC 无极性设计,直流电路安全工作上限 温度系数 X7R -55℃~+125℃,容值漂移≤±15%(25℃基准) 封装尺寸 0402(英制) 1.0mm×0.5mm×0.5mm(典型厚度),小型化优势 工作温度范围 -55℃~+125℃ 覆盖工业级与消费电子的宽温需求 等效串联电阻(ESR) ≤50mΩ(1kHz下典型值) 高频损耗低,适合射频信号处理

三、X7R介质的特性与优势

X7R是MLCC领域最常用的宽温稳定型介质,其特性直接决定了产品的适用场景:

  1. 温度稳定性突出:在-55℃至+125℃范围内,容值变化控制在±15%以内,远优于Y5V等高容介质(Y5V漂移可达±20%以上);
  2. 容值密度平衡:介电常数(εr)约2000~4000,可在0402小封装内实现1nF稳定容值,避免NPO介质(εr<100)容值过小的局限;
  3. 无极性设计:陶瓷叠层无正反区分,贴装无需识别极性,大幅简化SMT生产流程;
  4. 成本可控:相比NPO高精度介质,X7R成本降低30%以上,适合量产型产品。

四、0402封装的工艺适配性

0402封装是当前电子设备小型化的核心载体,该产品在封装层面的优势包括:

  1. 体积微型化:仅为0603封装的1/4体积,可在智能手机、可穿戴设备等高密度PCB上实现多路去耦;
  2. 贴装兼容性:支持回流焊、激光焊等主流SMT工艺,贴装精度可达±0.05mm,适配自动化生产线;
  3. 高频特性:低ESR(1kHz下≤50mΩ)与低ESL(等效串联电感≤1nH),可有效抑制电源纹波,提升射频信号完整性;
  4. 机械可靠性:采用陶瓷-金属共烧工艺,焊点抗振动性能符合IPC-A-610标准(振动频率10~2000Hz,加速度1.5g)。

五、典型应用场景

结合参数与特性,该产品主要应用于以下领域:

  1. 消费电子终端:
    • 智能手机/平板:CPU、基带芯片的电源去耦电容(抑制电压波动);
    • 可穿戴设备(智能手表、手环):传感器模块的信号耦合(如心率、加速度传感器);
  2. IoT与小型家电:
    • 智能家居节点(温湿度传感器):电源滤波(稳定3.3V/5V供电);
    • 蓝牙耳机/音箱:音频信号耦合(1nF容值匹配音频带宽);
  3. 工业控制模块:
    • 小型PLC输入输出板:数字信号滤波(减少电磁干扰);
    • 电机驱动辅助电路:电压稳定电容(适配24V~48V低压系统)。

六、品牌可靠性与合规性

HRE芯声作为国内专业MLCC制造商,该产品的可靠性与合规性已通过多重验证:

  1. 可靠性测试:
    • 高温老化(125℃/1000h):容值变化≤±5%,无失效;
    • 湿度测试(85℃/85%RH/500h):绝缘电阻≥10^9Ω,性能稳定;
  2. 合规认证:
    • 符合RoHS 2.0、REACH法规,无铅环保;
    • 部分批次支持汽车级AEC-Q200认证(需确认具体订货代码);
  3. 量产保障:月产能达1000万只以上,可满足中大型客户的量产需求。

该产品通过平衡小型化、稳定性与成本,成为消费电子、IoT等领域的通用MLCC首选方案,适配多数主流电子设备的设计需求。

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
