CGA0805X7R225K250MT 多层陶瓷贴片电容(MLCC)产品概述

CGA0805X7R225K250MT是芯声电子(HRE) 推出的通用型多层陶瓷贴片电容(MLCC),针对低中压电路的滤波、耦合、去耦核心需求设计,兼具小型化、宽温稳定、高可靠性特点,广泛适配消费电子、工业控制、通信设备等领域。

一、产品基本信息与编码解析

该型号遵循MLCC行业编码规则,各字符含义明确:

  • CGA:多层陶瓷电容前缀标识;
  • 0805:英制封装尺寸(对应公制2.0mm×1.25mm),适配常规SMT贴装线;
  • X7R:温度系数与介质材料(钛酸钡基陶瓷);
  • 225:容值编码(22×10⁵ pF = 2.2μF);
  • K:容值精度(±10%);
  • 250:额定直流电压(25V);
  • MT:封装制程后缀(无引脚贴片式)。

品牌为芯声电子(HRE),国内专注MLCC研发的主流厂商,产品覆盖通用至高容值系列。

二、核心性能参数详解

1. 容值与精度

标称容值2.2μF,精度±10%,属于工业级通用范围——既满足多数滤波电路对容值偏差的容忍度,又避免高精度(±5%)带来的成本上升。

2. 额定电压与耐压

额定直流电压25V,稳定适配直流/低频交流电路。建议遵循80%电压降额原则(工作电压≤20V),延长寿命并降低失效风险。

3. 温度特性

采用X7R介质,符合EIA标准:

  • 工作温度:-55℃ ~ +125℃;
  • 容值变化:±15%(相对25℃基准)。 相较于Y5V(±22%),X7R稳定性更优,适合宽温环境(如汽车电子、户外工业设备)。

三、封装与物理特性

1. 0805封装优势

尺寸紧凑(2.0mm×1.25mm×0.8mm左右),适配小型化电子设备(手机、智能穿戴、小型路由器),优化PCB布局空间。

2. 贴片式结构

无引脚设计,端电极(镍/锡镀层)直接焊接,兼容回流焊、波峰焊等SMT工艺,贴装效率高,适合批量生产。

四、典型应用场景

因参数均衡,覆盖多领域通用需求:

  1. 消费电子:手机、平板的3.3V/5V电源滤波、音频信号耦合;
  2. 工业控制:PLC模块、传感器信号调理的去耦电容,满足-40℃~+85℃工业环境;
  3. 通信设备:路由器、交换机的高速信号滤波,降低电磁干扰(EMI);
  4. 汽车电子:车载导航、辅助驾驶低功耗模块(部分批次符合AEC-Q200车规)。

五、可靠性与环保特性

1. 可靠性测试

通过多项行业标准验证:

  • 高温存储(125℃/1000h):容值变化≤±10%,绝缘电阻≥10⁹Ω;
  • 温度循环(-55℃~+125℃/1000次):无开裂、性能无衰减;
  • 焊接耐热(回流焊峰值260℃/10s):端电极无脱落。

2. 环保合规

符合RoHS 2.0(无铅/镉/汞)、REACH法规,适配欧盟、北美市场环保准入。

六、选型与使用注意事项

  1. 电压降额:避免长期工作在额定电压附近,建议≤20V;
  2. 焊接温度:回流焊峰值≤260℃,波峰焊≤240℃,防止介质开裂;
  3. 静电防护:MLCC对静电敏感,存储/贴装需防静电包装与设备;
  4. 高频应用:>1MHz时需考虑介质损耗导致的容值下降,可适当增大选型容值。

综上,CGA0805X7R225K250MT是性价比突出的通用MLCC,以0805封装实现2.2μF稳定输出,适配多场景低中压电路需求,是电子设计平衡性能与成本的优选方案。

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
