HRE芯声CGA1206X7R224K251NT多层陶瓷电容(MLCC)产品概述

一、产品基本信息与核心参数梳理

CGA1206X7R224K251NT是HRE芯声推出的通用型多层陶瓷电容(MLCC),型号命名遵循行业标准:CGA为MLCC封装标识,1206对应英制封装尺寸(0.12×0.06英寸,公制3.2×1.6mm),X7R为温度系数(-55℃~+125℃,容值变化±15%),224表示标称容值220nF(22×10⁴pF),K为容值精度±10%,251对应额定电压250V DC,NT为品牌定制后缀。

核心参数如下表所示:

参数项 具体参数 型号 CGA1206X7R224K251NT 品牌 HRE(芯声) 产品类型 多层陶瓷电容(MLCC) 封装尺寸 1206(3.2mm×1.6mm×1.2mm) 标称容值 220nF(224) 容值精度 ±10%(K档) 额定电压 250V DC 温度系数 X7R(-55℃~+125℃,ΔC≤±15%) 工作温度范围 -55℃ ~ +125℃ 介电材料 钛酸钡基陶瓷 环保标准 RoHS 2.0、REACH(无铅无卤)

二、关键特性与设计优势

该产品针对通用电子设计的核心需求,具备以下优势:

  1. 宽温稳定可靠:X7R介质的容值变化率控制在±15%以内,覆盖工业级宽温范围,无需额外降额或补偿即可适配-55℃至+125℃的环境;
  2. 中高压适配性:250V DC额定电压满足中高压电路的滤波、耦合需求,可替代同参数电解电容实现体积缩小80%以上;
  3. 小体积大容量:1206封装下实现220nF容值,适合便携式设备、物联网终端的紧凑布局;
  4. 高可靠性设计:采用多层共烧工艺,镍电极与陶瓷层结合紧密,通过500次温度循环、1000小时高温高湿测试;
  5. 成本平衡设计:±10%精度满足90%以上通用电路需求,避免高精度带来的成本冗余,适合批量生产。

三、典型应用场景

该产品广泛应用于以下电子领域:

  1. 电源系统:开关电源输出滤波、DC-DC转换器输入/输出去耦、LED驱动电源滤波(适配200V以内工作电压);
  2. 工业控制:PLC模块、变频器信号耦合、工业传感器电源滤波(宽温适配车间环境);
  3. 消费电子:液晶电视电源板、机顶盒电源模块、智能音箱滤波电路(小体积适配家电紧凑设计);
  4. 物联网终端:智能电表、环境传感器节点电源滤波(低功耗兼容终端需求);
  5. 汽车辅助系统:车载充电器、车灯控制电路滤波(适配车载-40℃~+85℃环境)。

四、封装与可靠性说明

  1. 封装细节:1206封装的电极端为镍镀层+表面镀锡,兼容回流焊、波峰焊工艺;焊盘需匹配3.2mm×1.6mm,焊接时需确保电极与焊盘对齐(接触面积≥80%);
  2. 可靠性测试:HRE芯声对该产品进行严格验证,关键结果如下:
    • 温度循环(-55℃~125℃,500次):容值变化≤±10%,无开路/短路;
    • 高温高湿(85℃/85%RH,1000小时):容值变化≤±15%,绝缘电阻≥1GΩ;
    • 耐电压测试(2.5×VR=625V DC,1分钟):无击穿、无漏电流超标;
  3. 环保合规:符合RoHS 2.0(无Pb、Cd、Hg等有害物质)、REACH SVHC要求,适合出口市场。

五、应用注意事项

为确保性能与寿命,需注意以下要点:

  1. 电压降额:实际工作电压建议不超过额定电压的80%(200V DC),长期过压会加速容值衰减;
  2. 焊接工艺:回流焊峰值温度控制在230℃~245℃(时间≤10秒),波峰焊温度≤260℃(时间≤5秒);
  3. 机械应力:焊接后避免过度弯折PCB(弯曲半径≥10mm),远离应力集中区域;
  4. 温度限制:不要在超过125℃的环境中连续工作,否则容值变化会超出规格;
  5. 极性说明:MLCC为无极性电容,安装无需区分正负极,但需避免虚焊。

该产品作为HRE芯声的通用型中高压MLCC,平衡了性能、成本与可靠性,可广泛替代同参数传统电容,满足多数中低压至中高压电子设计的需求。

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
