C0603C104K3RACAUTO 产品概述

C0603C104K3RACAUTO是KEMET基美推出的通用型表面贴装多层陶瓷电容(MLCC),专为高密度、宽温度范围的电子电路设计,核心参数匹配100nF/25V/X7R的通用需求,广泛覆盖消费电子、工业控制及小型化设备领域。

一、产品基本信息汇总

该型号为KEMET 0603封装系列的核心产品,基础参数明确:

  • 产品类型:多层陶瓷电容(MLCC)
  • 封装规格:0603(表面贴装SMD)
  • 容值:100nF(编码“104”,即10×10⁴pF)
  • 精度:±10%(编码“K”)
  • 额定电压:25V(直流工作电压)
  • 温度系数:X7R
  • 品牌:KEMET(基美)

二、关键性能参数解析

2.1 容值与精度

100nF是电子电路中最常用的容值之一,±10%的精度可满足非高精度需求场景(如电源滤波、一般信号耦合),既避免了高精度电容的成本冗余,又能覆盖80%以上的通用电路要求。

2.2 温度系数X7R

X7R是MLCC的常见温度系数类别,核心特性:

  • 工作温度范围:-55℃ ~ +125℃
  • 容值变化率:≤±15%(全温度范围内) 相比Y5V(容值变化±20%以上),X7R的容值稳定性更好,适合环境温度波动较大的场景(如汽车电子、户外设备)。

2.3 额定电压与降额要求

额定电压25V(直流),实际应用需遵循电压降额原则:

  • 建议工作电压不超过20V(20%降额),避免长期过压导致电容老化失效;
  • 交流电压需结合峰值计算,确保峰值电压≤25V。

三、封装与尺寸规格

0603封装为英制尺寸编码,具体参数:

  • 长×宽:0.06英寸(1.6mm)×0.03英寸(0.8mm)
  • 厚度:约0.8mm(典型值,以KEMET官方 datasheet 为准)
  • 焊盘适配:标准0603焊盘(长1.0-1.2mm,宽0.6-0.8mm)

该封装适合高密度PCB设计,可有效缩小产品体积,常见于智能手机、智能穿戴、IoT模块等小型化设备。

四、典型应用场景

因参数均衡、封装小巧,该产品广泛应用于:

  1. 电源滤波:DC-DC转换器输出端、线性电源滤波;
  2. 去耦电容:IC电源引脚附近(如MCU、FPGA),抑制高频噪声;
  3. 信号耦合:音频信号、数字总线(I2C、SPI)耦合;
  4. 小型电子设备:智能手环、蓝牙耳机、智能家居传感器;
  5. 汽车电子(潜在):型号“AUTO”后缀暗示支持汽车级应用,可用于车载小功率电路(仪表盘、中控辅助)。

五、品牌与可靠性优势

KEMET作为全球被动元器件龙头,该产品具备:

  • 环保合规:符合RoHS 2.0、REACH标准,无铅镉等有害物质;
  • 可靠性测试:通过温度循环(-55℃~125℃,1000次)、湿度老化(85℃/85%RH,1000小时)、焊接热冲击测试;
  • 一致性好:批量生产参数差异控制在±5%以内,避免同批次性能波动。

六、选型与使用注意事项

  1. 温度范围:严禁超过-55℃~+125℃,避免低温脆化或高温容值漂移;
  2. 焊接工艺:优先回流焊(峰值230-260℃,时间≤30秒),手工焊接控制烙铁温度≤350℃、时间≤5秒;
  3. 极性:MLCC无极性,0603封装无正反要求;
  4. 存储条件:未开封产品存于湿度≤60%、温度15-35℃环境,开封后12个月内使用完毕,防止焊盘氧化。

综上,C0603C104K3RACAUTO是高性价比通用MLCC,适合大多数电子电路的滤波、去耦及耦合需求,是小型化、宽温设备的优选元件。

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
