CL21A476MPYNNWE 片式陶瓷电容产品概述

CL21A476MPYNNWE是三星电子(SAMSUNG)推出的一款X5R介质片式多层陶瓷电容(MLCC),专为低电压、高容值需求的表面贴装应用设计,具备尺寸紧凑、稳定性良好、适用场景广泛等特点,是消费电子、小型工业设备等领域的常用基础元器件。

一、产品核心身份与定位

该型号属于三星CL21系列MLCC产品,聚焦0805英制封装(对应公制尺寸2.0mm×1.25mm)的小尺寸高容值需求场景,主要解决低电压电路中的滤波、耦合、旁路等功能,平衡了容值密度与温度稳定性,适合对尺寸敏感但对容值变化要求适中的应用。

二、关键技术参数解析

2.1 容值与精度

标称容值为47μF(即47微法,对应电容标识“476”——1μF=10⁶pF,47μF=47×10⁶pF=476pF),精度为**±20%**,属于工业级通用精度范围,满足大多数非高精度电路的需求,无需额外容值筛选即可批量应用。

2.2 额定电压与介质

额定电压为10VDC,适用于低电压供电的电子设备(如5V/3.3V系统的电源滤波);介质类型为X5R,是MLCC中兼顾容值密度与温度稳定性的主流介质之一。

2.3 温度特性

X5R介质的温度适用范围为**-55℃至+85℃**,在该区间内电容容值变化≤±15%,远优于Y5V等低成本介质(Y5V容值变化可达±20%~+82%/-82%),能在环境温度波动较大的场景下保持稳定性能。

三、封装与物理特性

该产品采用0805英制表面贴装封装,典型物理参数如下:

  • 长度:2.0±0.2mm
  • 宽度:1.25±0.15mm
  • 厚度:1.2±0.2mm(批次间略有差异)
  • 重量:约0.02g(轻小型,适配高密度PCB布局)

封装符合RoHS 2.0环保标准(无铅、无镉、无汞),兼容主流SMT贴装设备,焊接可靠性高,可通过回流焊、波峰焊实现批量生产。

四、性能优势与应用场景

4.1 核心性能优势

  1. 高容值密度:在0805小封装内实现47μF容值,解决小尺寸设备的大容量需求;
  2. 宽温稳定性:X5R介质在-55℃~+85℃区间容值变化小,避免温度波动导致电路性能下降;
  3. 高可靠性:采用多层陶瓷叠层工艺,内部电极均匀,25℃/额定电压下平均寿命超10万小时。

4.2 典型应用场景

  • 消费电子:智能手机、平板电脑的DC-DC滤波,蓝牙耳机、智能手环的供电滤波与信号耦合;
  • 小型工业设备:传感器模块、小型PLC的电源旁路电容,低电压控制电路的耦合电容;
  • 物联网设备:智能插座、温湿度传感器的电源滤波与信号隔离。

五、品牌与品质保障

三星电子作为全球MLCC主要供应商,具备完善的生产与品控体系:

  • 产品符合IEC 60384-14(陶瓷电容国际标准)、JIS C 5102(日本工业标准);
  • 批量供货稳定,满足中小批量到大规模生产需求;
  • 提供完整 datasheet 与技术支持,助力客户快速选型与设计。

综上,CL21A476MPYNNWE凭借高容值密度、宽温稳定性与小尺寸优势,成为低电压电子设备滤波、耦合等功能的理想选择,适用于对成本与性能平衡要求较高的通用场景。

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
