CGA1206X7R103K102MT多层陶瓷电容产品概述

一、产品核心身份与命名解析

CGA1206X7R103K102MT是HRE芯声推出的工业级多层陶瓷电容(MLCC),其命名严格遵循行业通用规则,各部分含义清晰:

  • CGA:HRE芯声对高压MLCC的系列代号,主打高压耐受与宽温稳定特性;
  • 1206:英制贴片封装尺寸(对应公制3.2mm×1.6mm),适配常规SMT产线;
  • X7R:温度系数类别(-55℃~+125℃工作范围,容值变化≤±15%);
  • 103:容值代码(10×10³pF=10nF);
  • K:容值精度(±10%);
  • 102:额定电压代码(10×10²V=1000V=1kV直流);
  • MT:HRE内部工艺后缀(对应标准卷带盘装,1000pcs/盘,适配自动化贴装)。

二、关键电性能参数详解

该产品核心电性能聚焦高压耐受、宽温稳定、中等容值三大方向,具体参数如下:

  1. 容值与精度:10nF(103)±10%(K),满足工业级电路对容值一致性的基本要求;
  2. 额定电压:1kV直流(DC),是同封装(1206)中少有的高压规格,可直接用于高压滤波、EMI抑制场景;
  3. 温度特性:X7R类别,-55℃~+125℃范围内容值漂移≤±15%,远优于Y5V等低成本温漂型电容;
  4. 损耗与绝缘:1kHz下损耗角正切(tanδ)≤0.015(典型值),绝缘电阻(IR)≥10⁹Ω·μF(25℃、100V DC下),确保低功耗与高可靠性;
  5. 频率特性:谐振频率(SRF)约10MHz(典型值),在射频/中频电路中可实现有效滤波。

三、封装与物理特性

1206封装是贴片电容的主流规格,该产品物理参数适配高密度PCB设计:

  • 尺寸:3.2mm(长)×1.6mm(宽)×1.6mm(厚,典型值);
  • 端电极:镍(Ni)打底+锡(Sn)镀层,符合RoHS 2.0环保标准,焊接兼容性强(可通过回流焊、波峰焊);
  • 包装:卷带盘装(1000pcs/盘),每盘带标有料号、数量、批次,方便SMT产线追溯。

四、温度特性与场景适配性

X7R是工业级MLCC的核心温度系数类别,其优势在于宽温区容值稳定:

  • 对比NPO(零温漂,但容值≤1nF):X7R可实现10nF中等容值,兼顾稳定性与实用性;
  • 对比Y5V(容值大但温漂≥±20%):X7R的温度适应性更适合极端环境(如车载、户外工业设备);
  • 典型应用场景中,该电容可稳定工作于**汽车发动机舱(-40℃+120℃)、工业变频器(-20℃+85℃)、通信基站电源(-10℃~+55℃)**等宽温区域。

五、适用场景与应用优势

该产品针对高压、宽温、高密度需求设计,核心应用场景包括:

  1. 工业电源:高压滤波(如开关电源输出端、逆变器母线)、EMI抑制(差模/共模滤波);
  2. 汽车电子:车载高压辅助电源、电池管理系统(BMS)高压采样、LED大灯驱动;
  3. 通信设备:基站射频模块电源滤波、光传输设备高压偏置电路;
  4. 医疗设备:监护仪高压供电滤波、诊断设备EMI防护(需高可靠性)。

应用优势总结:

  • 高压耐受(1kV):减少串联电容数量,简化电路设计;
  • 宽温稳定(X7R):降低环境温度对电路性能的影响;
  • 小封装(1206):适配高密度PCB布局,降低设备体积;
  • 品牌可靠性:HRE芯声符合ISO9001、IATF16949认证,产品通过高温存储(125℃×1000h)、温度循环(-55~125℃×1000次)等可靠性测试。

六、注意事项

  1. 电压降额:交流(AC)场景下需按峰值电压≤额定电压的70% 降额使用(如AC 110V峰值约155V,可直接使用;AC 220V峰值约311V,需降额至70%即218V,满足要求);
  2. 焊接温度:回流焊峰值温度≤245℃(10s内),避免高温损坏陶瓷介质;
  3. 机械应力:贴片后避免PCB弯曲(弯曲度≤0.5%),防止电容开裂。

综上,CGA1206X7R103K102MT是一款兼顾高压、宽温、小封装的工业级MLCC,可满足多数中高压电路的滤波、防护需求,是HRE芯声在高压陶瓷电容领域的代表性产品。

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.
