CGA0402X5R105M100GT 多层陶瓷电容(MLCC)产品概述

CGA0402X5R105M100GT是HRE芯声推出的通用型多层陶瓷电容(MLCC),针对小型化低电压电子设备设计,兼顾容量稳定性、封装密度与成本优势,广泛适配消费电子、IoT终端等场景。以下从核心属性、性能参数、封装特性等维度展开概述:

一、产品标识与基本属性解析

该型号遵循MLCC行业通用编码规则,各字符含义明确:

  • CGA:HRE芯声通用MLCC系列前缀,代表多层陶瓷电容;
  • 0402:英制封装尺寸(0.04英寸×0.02英寸),对应公制1005封装(长1.0mm×宽0.5mm);
  • X5R:温度系数类别,符合EIA标准:工作温度范围**-55℃~+85℃**,容量变化率±15%(典型值);
  • 105:容值编码,10×10⁵ pF=1μF(1000nF);
  • M:容值精度标识,代表**±20%**;
  • 100:额定直流电压(WVdc),即10V;
  • GT:HRE内部封装/批次标识,代表特定生产工艺或封装细节(如电极厚度优化)。

二、核心性能参数详解

该产品的核心参数匹配通用低电压电路需求,关键指标如下:

  1. 容值与精度:标称1μF,±20%精度,满足滤波、耦合等基础功能的容差要求(无需高精密场景时可降低成本);
  2. 额定电压:10V DC,实际应用需遵循70%降额原则(建议工作电压≤7V),避免长期高压导致容量衰减;
  3. 温度特性:X5R温度系数,在-55℃~+85℃范围内容量变化≤±15%,优于Y5V等低价电容的稳定性,适合环境温度波动较大的场景;
  4. 损耗特性:典型损耗角正切(tanδ)≤1%(1kHz、25℃测试条件),低损耗可减少电路发热,提升电源效率;
  5. 绝缘电阻:25℃下≥10⁹Ω·μF,确保信号完整性,避免漏电流干扰敏感电路。

三、封装与物理特性

0402封装是当前小型化电子设备的主流封装之一,该产品的物理特性适配高密度布局:

  • 尺寸参数:公制1005封装,长1.0±0.2mm×宽0.5±0.2mm×厚0.5±0.1mm,体积仅约0.25mm³,可显著节省PCB空间;
  • 电极材料:采用银钯(Ag-Pd)合金电极,兼容无铅回流焊工艺(峰值温度260℃,保持时间10s),符合RoHS 2.0与REACH环保标准;
  • 焊接兼容性:支持表面贴装技术(SMT),可通过回流焊、波峰焊(需适配夹具)实现批量生产,焊点可靠性符合IEC 60068-2-20标准。

四、典型应用场景

该产品的参数组合使其成为以下场景的优选电容:

  1. 低电压消费电子:智能手机、智能手表的电源旁路滤波(如电池供电电路)、音频信号耦合;
  2. IoT终端设备:蓝牙模块、WiFi模块的射频旁路电容,传感器节点的电源滤波;
  3. 小型化可穿戴设备:蓝牙耳机、智能手环的核心电路,适配高密度PCB布局;
  4. 工业控制辅助电路:低电压PLC(可编程逻辑控制器)的信号耦合、滤波(需确认温度环境符合-55℃~+85℃)。

注:因额定电压为10V,不适用于汽车电子(通常需25V以上)、高压工业设备等场景。

五、可靠性与环境适应性

HRE芯声针对该产品做了多项可靠性验证,确保长期稳定运行:

  • 寿命测试:在额定电压(10V)、85℃环境下,寿命≥1000小时,容量变化≤±10%;
  • 耐湿测试:40℃/93%RH环境下放置1000小时,绝缘电阻≥10⁸Ω·μF,无明显性能衰减;
  • 机械可靠性:通过振动测试(10~2000Hz,加速度2g)与冲击测试(100g,10ms),无开裂、开路现象。

六、品牌与供货优势

HRE芯声是国内专注于MLCC研发与制造的企业,CGA系列具有以下优势:

  • 成本效益:X5R材料比X7R成本更低,同时满足通用场景的稳定性需求;
  • 供货稳定:月产能覆盖百万级,支持小批量定制与大批量采购;
  • 技术支持:提供选型手册、焊接工艺指南,协助客户优化电路设计。

综上,CGA0402X5R105M100GT是一款高性价比、小型化通用MLCC,适合低电压、高密度布局的电子设备,可满足消费电子、IoT等领域的基础滤波、耦合需求。

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
