C0603C105K3RAC7867 产品概述

C0603C105K3RAC7867是KEMET基美推出的一款表面贴装多层陶瓷电容器(MLCC),隶属于SMD Comm X7R系列,针对电子电路中的旁通、去耦等基础滤波场景设计,兼具小型化、宽温稳定性与高可靠性,是消费电子、工业控制等领域的常用元件。

一、产品基本定位

该产品属于通用型MLCC,核心定位为低压电路的高频噪声滤除与电源稳定,适配高密度PCB布局需求。其封装采用0603(1608公制)小型化设计,卷带(TR)包装适合自动化生产,零件状态为在售,可直接采购应用于各类电子设备。

二、核心技术参数详解

以下为产品关键参数的具体说明,覆盖电气性能、物理尺寸与环境适应性:

  • 电容值:1 µF(标识代码“105”,即10×10⁵ pF);
  • 容差:±10%,满足多数滤波电路的精度需求;
  • 额定电压:25V DC,适用于低压供电系统(如3.3V、5V电路);
  • 温度系数:X7R(行业标准温度特性:-55°C~125°C范围内,电容变化率≤±15%);
  • 工作温度范围:-55°C ~ 125°C,可适应极端环境(如汽车电子、工业户外设备);
  • 封装尺寸:长1.60mm×宽0.80mm(0.063"×0.031"),厚度最大0.87mm(0.034");
  • 安装类型:表面贴装(SMD),兼容标准回流焊工艺;
  • 包装方式:卷带(TR),每卷数量符合行业标准,便于自动化贴装。

三、典型应用场景

结合产品参数与设计定位,主要应用于以下场景:

  1. 旁通电路:电源输入/输出端的高频噪声滤除,抑制电磁干扰(EMI);
  2. 去耦电路:集成电路(IC)电源引脚与地之间的去耦,稳定供电电压,减少纹波;
  3. 消费电子终端:智能手机、平板电脑、可穿戴设备的信号滤波与电源稳定;
  4. 工业控制模块:PLC、传感器节点等宽温环境下的电路滤波;
  5. IoT终端设备:低功耗无线模块的电源去耦,保障信号传输稳定性。

四、关键性能优势

该产品的核心优势集中在环境适应性、小型化与可靠性三方面:

  1. 宽温稳定性能:X7R温度系数确保-55°C~125°C范围内电容值变化小,避免极端温度下滤波效果衰减;
  2. 小型化高密度设计:0603封装适配当前电子设备“轻薄化”趋势,可有效节省PCB空间;
  3. 高可靠性:KEMET成熟的MLCC工艺,低介质损耗,长期工作下性能稳定,故障率低;
  4. 安装便捷性:卷带包装支持自动化贴装,提高生产效率,降低人工成本;
  5. 电压覆盖性:25V额定电压满足多数低压电路需求,无需额外选型适配。

五、选型与使用注意事项

为保障产品性能与电路可靠性,需注意以下要点:

  1. 电压裕量:实际工作电压需低于25V额定值,建议保留10%~20%的电压裕量(如最大工作电压不超过20V),避免过压损坏;
  2. 温度匹配:确认工作环境温度在-55°C~125°C范围内,若超出需更换其他温度系数(如X5R、Y5V)的电容;
  3. 精度适配:±10%容差适合滤波场景,若用于定时、谐振等对电容精度要求高的电路,需选择±5%或更紧容差的产品;
  4. 焊接工艺:表面贴装需遵循KEMET推荐的回流焊温度曲线,避免热应力导致电容开裂;
  5. 静电防护:虽陶瓷电容抗静电能力较强,但仍需在生产、测试过程中做好ESD防护,避免静电损坏。

综上,C0603C105K3RAC7867是一款性价比高、适配性强的通用MLCC,可满足多数低压电子电路的旁通、去耦需求,是电子工程师选型的常用元件之一。

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
