CGA1206X7R103K101KT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

CGA1206X7R103K101KT是HRE芯声推出的一款通用型贴片多层陶瓷电容(MLCC),型号编码直接映射核心参数:

  • 前缀“CGA”为陶瓷电容通用标识;
  • “1206”为英制封装尺寸(对应公制3216,长3.2mm×宽1.6mm);
  • “X7R”为温度系数;
  • “103”代表容值(10×10³pF=10nF);
  • “K”表示容值精度±10%;
  • “101”对应额定电压100V DC。

该产品采用陶瓷叠层工艺,无极性设计,兼容主流回流焊/波峰焊工艺,是中低压电路滤波、耦合的高性价比选型。

二、核心性能参数

参数项 具体规格 说明 封装尺寸 1206(3216) 英制尺寸,适合高密度PCB布局 标称容值 10nF(103) 10×10³皮法=10纳法 容值精度 ±10%(K档) 工业级通用精度,满足多数应用需求 额定电压 100V DC 连续工作电压上限,降额使用可靠性更高 温度系数 X7R -55℃~+125℃范围内容值变化≤±15% 材质 多层陶瓷(MLCC) 叠层结构,体积小、容量密度高 引脚镀层 Ni/Sn(镍锡) 符合RoHS环保标准,焊接兼容性好 工作温度范围 -55℃~+125℃ 覆盖工业级宽温场景

三、关键特性解析

1. 宽温区稳定性优异

X7R材质是目前工业级MLCC的主流选择,在-55℃至+125℃的宽温度范围内,容值变化控制在±15%以内,可稳定适配户外设备、汽车电子(非车载核心)、工业PLC等对温度敏感的场景,避免因温度波动导致电路性能漂移。

2. 中压场景适应性强

100V额定电压覆盖了多数中压电路需求:

  • 开关电源输入/输出滤波(市电整流后电压通常在100V以下);
  • 工业传感器信号隔离耦合;
  • 小型电机驱动电路的旁路滤波。
    若按20%降额使用(实际工作电压≤80V),可进一步提升长期可靠性。

3. 封装紧凑,适配高密度设计

1206封装(3.2×1.6mm)比0805(2.0×1.2mm)容量密度更高,比1812(4.5×3.0mm)体积更小,适合消费电子(如智能家居控制板)、小型通信设备(如路由器)等对PCB空间要求严格的场景。

4. 高可靠性与工艺兼容性

  • 无极性设计:无需区分正负极,焊接错误率低;
  • 回流焊适配:支持245±5℃峰值温度(时间≤10s),符合主流SMT产线工艺;
  • 长期稳定性:通过125℃×1000h高温存储、-55~125℃×1000次温度循环测试,满足工业级可靠性要求。

四、典型应用场景

1. 电源系统滤波

  • 开关电源输入滤波:抑制市电纹波,提升输出电压稳定性;
  • 线性电源输出滤波:减少噪声干扰,适配精密模拟电路;
  • 电池管理系统(BMS):辅助电压检测电路的滤波。

2. 信号耦合与隔离

  • 音频电路:手机、音箱的音频信号耦合,隔离直流分量;
  • 通信电路:蓝牙、WiFi模块的射频信号耦合,提升传输信噪比;
  • 工业传感器:温度、压力传感器的信号隔离,避免共地干扰。

3. 数字电路旁路

  • CPU、FPGA等核心芯片的电源旁路:快速吸收瞬态电流,降低电源噪声;
  • 单片机(MCU)周边电路:辅助时钟电路、复位电路的滤波。

4. 消费电子与工业控制

  • 智能家居:智能开关、传感器节点的控制电路;
  • 小型家电:洗衣机、空调的控制面板滤波;
  • 工业PLC:I/O模块的信号滤波与耦合。

五、选型匹配参考

若需调整参数适配特定场景,可参考以下替代型号:

  • 更高精度:选择J档(±5%),型号为CGA1206X7R103J101KT;
  • 更高电压:200V需求可选CGA1206X7R103K201KT;
  • 更小封装:0805封装(2.0×1.2mm)可选CGA0805X7R103K101KT;
  • 更高温稳定性:若需-55~150℃范围,可选择X8R材质(容值变化≤±15%),型号如CGA1206X8R103K101KT。

六、存储与使用注意事项

  1. 存储条件:常温干燥环境(温度-40~60℃,湿度≤60%RH),开封后建议12个月内使用完毕;
  2. 焊接工艺:优先采用回流焊,波峰焊需控制浸锡时间≤3s(温度≤240℃);
  3. 静电防护:MLCC对静电敏感,操作时需佩戴防静电手环,使用防静电包装。

CGA1206X7R103K101KT凭借稳定的性能、紧凑的封装和高性价比,成为中低压电路中滤波、耦合的经典选型,广泛覆盖工业与消费电子领域的多数应用场景。

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
