三星CL21B475KPFNNNE 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本身份与定位

三星CL21B475KPFNNNE是三星电机推出的通用型贴片多层陶瓷电容(MLCC),隶属于三星CL21系列核心产品线。该型号针对消费电子、IoT设备等紧凑电路场景优化,是当前市场应用最广泛的中低电压MLCC之一。型号编码中,“CL21B”标识三星X7R介质电容系列,“475”对应容值规则,“K”明确精度等级,“PFNNNE”为封装及工艺代码,整体定位为“小体积、高稳定、性价比突出”的通用滤波/耦合电容。

二、关键电气性能参数

核心参数清晰适配多数电路需求,具体如下:

  • 容值:标称4.7μF(即47×10⁵ pF,符合MLCC“数字+倍率”标识规则),实际值范围4.23μF~5.17μF(±10%精度);
  • 额定电压:直流10V(DC10V),适用于低电压供电设备(如手机、智能手环),避免过压损坏;
  • 精度等级:±10%,满足消费电子、小型家电等场景的设计误差要求,无需高精度电容的场景下性价比显著;
  • 频率特性:X7R介质谐振频率适中(约100kHz级),兼顾低频滤波与中频耦合功能,适配信号传输场景。

三、封装与物理特性

采用0805封装(英制代码,对应公制2012尺寸),是电子设备中最常用的小型贴片封装:

  • 尺寸规格:长度2.0mm±0.2mm,宽度1.2mm±0.2mm,厚度0.8mm±0.1mm,体积仅约1.92mm³,可大幅压缩电路板面积;
  • 封装形式:无引线贴片设计,适配自动化SMT贴装工艺,生产效率比插件电容提升3倍以上;
  • 电极结构:两端金属电极(镍锡镀层),焊盘兼容性强,与主流PCB板(FR-4材质)焊接良率达99%以上。

四、材料特性与温度稳定性

核心采用X7R陶瓷介质,是MLCC中“容值-稳定性”平衡最优的介质之一:

  • 温度范围:工作温度-55℃~+125℃,覆盖室内外消费电子(如户外智能手表)、部分工业低功耗场景;
  • 温度稳定性:温度变化时电容值波动≤±15%,远优于Y5V介质(波动±20%以上),能保证电路在温差较大环境下性能稳定;
  • 介电常数:约3000~4000,相同封装下可实现更高容值,解决小体积与大容值的矛盾。

五、典型应用场景

凭借参数与封装的适配性,该电容广泛用于以下领域:

  1. 消费电子终端:智能手机主板电源旁路(过滤纹波)、蓝牙耳机信号耦合(音频传输);
  2. IoT智能设备:智能手环传感器模块滤波、智能插座低功耗电路耦合;
  3. 小型家电配件:遥控器电源滤波、LED台灯驱动电路耦合;
  4. 通信模块:BLE蓝牙模块信号滤波、WiFi模块噪声抑制。

六、可靠性与行业适配性

三星作为全球MLCC头部供应商,该产品可靠性符合行业严苛标准:

  • 环保合规:通过RoHS 2.0、REACH认证,无铅无镉,满足全球电子设备出口要求;
  • 可靠性测试:完成125℃/1000小时高温寿命测试、-55℃~+125℃温度循环测试(1000次),失效率≤0.1%;
  • 兼容性:适配Altium、Eagle等主流PCB设计软件的封装库,可直接替换同参数同封装的其他品牌MLCC(如村田GRM系列)。

综上,三星CL21B475KPFNNNE以“小体积、高稳定、广适配”为核心优势,成为消费电子、IoT等领域通用MLCC的优选之一,兼顾性能与成本控制,适合批量生产需求。

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
