CGA0402X5R225K350GT 多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与编码解析

CGA0402X5R225K350GT是芯声(HRE)品牌推出的0402封装多层陶瓷贴片电容(MLCC),型号编码直接映射核心参数,便于快速识别:

  • CGA:陶瓷电容通用编码前缀(行业通用标识);
  • 0402:英制封装尺寸(0.04英寸×0.02英寸,对应公制1.0mm×0.5mm);
  • X5R:介质材料与温度特性代码;
  • 225:容值编码(22×10⁵ pF = 2.2 μF);
  • K:精度等级(±10%);
  • 350:额定直流电压(35 V);
  • GT:产品等级/包装后缀(适配高速SMT贴装)。

二、关键电性能参数详解

作为Class II型高介电常数MLCC,该产品核心电性能满足多数低压电路需求:

  1. 容值与精度:标称容值2.2 μF,精度±10%(K档),覆盖滤波、耦合场景的误差要求;
  2. 额定电压:直流35 V,适配12 V/24 V低压电源系统,可承受短期过压(如电源瞬态波动≤40 V);
  3. 温度特性:X5R介质,工作温度范围**-55℃ ~ +85℃**,容值变化率≤±15%,兼顾容值密度与温度稳定性;
  4. 损耗与绝缘:1 kHz下损耗角正切(tanδ)≤1%,25℃下绝缘电阻(IR)≥10⁹ Ω·V,减少能量损耗与漏电流;
  5. 频率特性:0402封装寄生电感/电阻低,工作频率覆盖100 kHz ~ 100 MHz,适配高频滤波场景。

三、封装与物理特性

0402封装是小型化电子设备的主流选择,该产品物理特性如下:

  • 尺寸:公制1.0 mm(长)× 0.5 mm(宽)× 0.5 mm(厚,典型值),适配紧凑PCB布局;
  • 电极与镀层:镍(Ni)内层电极+纯锡(Sn)表面镀层,兼容无铅回流焊(260℃峰值温度,10 s焊接时间);
  • 包装形式:8 mm卷带包装(JEDEC标准),每卷10000 pcs,适配高速贴片机(速度≥15000 pcs/h);
  • 重量:约5 mg/pcs,轻量化设计适配便携设备(如智能手表、蓝牙耳机)。

四、材料特性与环境适应性

X5R介质是该产品的核心优势,平衡了容值密度与温度稳定性:

  • 容值密度:Class II型陶瓷介电常数(εᵣ)约20003000,是Class I型(如C0G,εᵣ≈100)的2030倍,实现小封装下高容值;
  • 温度范围:-55℃~+85℃覆盖多数消费电子(手机、平板)与一般工业设备(小型传感器)的环境温度;
  • 局限性:不适合极端高温(>85℃)或高精度(<±1%)场景,需结合需求选择(如汽车电子优先X7R,射频电路优先C0G)。

五、典型应用场景

该产品因小封装、高容值、低损耗的特点,广泛应用于:

  1. 消费电子:智能手机/平板的CPU/基带芯片电源去耦、音频接口滤波;
  2. 便携设备:蓝牙耳机的DC-DC转换滤波(减少纹波噪声)、智能手表的射频小信号旁路;
  3. 工业控制:小型PLC模块、温度传感器节点的辅助滤波(稳定模拟信号);
  4. 物联网设备:低功耗传感器、智能门锁的电源管理滤波。

六、可靠性与标准合规

芯声该产品符合行业主流可靠性与环保标准:

  • 可靠性测试:通过温度循环(-55℃~+85℃,1000次)、湿度老化(85℃/85%RH,1000 h)、耐焊接热测试,符合IEC 60384-14、JIS C 5101标准;
  • 环保合规:符合RoHS 2.0(无铅、无镉、无汞)、REACH SVHC要求,适配全球市场准入;
  • 品质保障:出厂前100%电性能检测,提供12个月品质保障期,批量订单可支持定制化测试。

七、品牌与产品定位

芯声(HRE)是国内专注MLCC研发生产的企业,产品覆盖02011206封装、1pF100μF容值范围。CGA0402X5R225K350GT定位为中低端消费电子与一般工业的性价比型MLCC,兼顾性能与成本,适配批量生产需求(月产能可达1亿pcs以上)。

该产品以小封装高容值、稳定的温度特性为核心竞争力,是替代进口同类产品的高性价比选择。

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
