KEMET C0805C104M5RAC7800 多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与定位

KEMET C0805C104M5RAC7800是基美电子(KEMET)推出的通用型多层陶瓷贴片电容(MLCC),属于0805封装系列的常规商业级产品。该型号针对中低功率电子电路的基础应用设计,兼顾体积紧凑性与电气稳定性,广泛适配消费电子、工业控制、通信设备等领域的常规场景需求。

二、基础电气与物理参数

该型号的核心参数清晰对应电路设计关键指标,具体如下:

  • 电气参数:容值标称100nF(即104pF),精度±20%(行业标识为"M"档);额定直流电压50V,满足低压电源系统的电压需求;25℃下绝缘电阻(1min测试)≥1GΩ,确保电路绝缘性能。
  • 物理参数:采用0805英制封装(对应公制2012规格),尺寸为2.0mm(长)×1.25mm(宽)×0.8mm(厚,典型值),体积小巧可有效节省PCB布局空间;端电极采用无铅镍锡镀层(Ni/Sn),符合RoHS 2.0环保标准,兼容现代SMT自动化生产。

三、介质材料与温度稳定性

产品采用X7R陶瓷介质,是MLCC中温度稳定型介质的典型代表,核心特性包括:

  • 温度范围:工作温度覆盖-55℃至+125℃,满足宽温环境下的应用;
  • 容量变化:在-55℃~+125℃范围内,容量变化控制在±15%以内(远优于Y5V等高容值介质的温度特性),适合对容量稳定性有一定要求的电路;
  • 电压相关性:X7R介质存在轻微电压依赖性,额定电压下容量较标称值略有下降(通常≤10%),设计时需适当降额或预留裕量。

四、封装设计与可靠性保障

基美针对0805封装的可靠性做了针对性优化:

  • 端电极结构:采用三层镀层设计(镍阻挡层+锡镀层),有效防止焊接时的金属扩散,提升焊接可靠性与耐老化性能;
  • 可靠性测试:通过基美内部及行业标准测试(如J-STD-020回流焊兼容性、高温存储125℃/1000h、温度循环-55℃~+125℃/500次),测试后容量变化、绝缘电阻等指标均符合规格要求;
  • 机械强度:0805封装的陶瓷芯片与端电极结合牢固,可承受常规SMT生产中的机械应力,避免开裂风险。

五、典型应用场景

该型号因参数均衡、成本可控,适用于以下场景:

  1. 电源滤波:直流电源模块的输入/输出滤波、稳压电路的去耦,稳定电压波动;
  2. 信号耦合:音频信号、低速数字信号(如UART、SPI)的耦合,实现信号隔离;
  3. 旁路电容:IC芯片引脚的旁路,抑制高频噪声,提升电路抗干扰能力;
  4. 消费电子:手机、平板、智能电视的电源管理模块、音频电路;
  5. 工业控制:PLC模块、传感器接口电路的滤波与耦合(非汽车级高可靠性场景)。

六、选型与使用注意事项

为确保产品性能与寿命,使用时需注意:

  1. 电压降额:建议实际工作电压不超过额定电压的80%(即40V以下),延长电容寿命;
  2. 温度控制:避免工作温度超过125℃,防止介质老化与容量衰减;
  3. 焊接工艺:回流焊峰值温度控制在245℃以内,时间不超过10s,避免过热损坏;
  4. 机械应力:PCB弯曲度不超过0.5%,防止电容开裂;
  5. 容值裕量:设计时考虑电压、温度对容量的影响,预留10%~15%的裕量。

该型号作为基美常规MLCC产品,凭借稳定的性能与成熟的工艺,成为电子设计中基础电容选型的可靠选择。

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
