CL21B225KOFVPNE 多层陶瓷电容器(MLCC)产品概述

一、产品定位与核心身份

CL21B225KOFVPNE是三星电机(SAMSUNG ELECTRO-MECHANICS) 推出的通用型多层陶瓷电容器(MLCC),隶属于CL21B系列产品线。该型号主打“小体积封装+宽温稳定特性”,适配中低压、对温度可靠性有要求的电子电路,是消费电子、工业控制等领域的主流选型之一,兼顾性能与成本效益。

二、关键电气参数详解

该型号参数明确对应电路设计核心需求,关键指标如下:

  1. 容值与精度:标称容值2.2μF(由“225”代码标识:22×10⁵ pF=2.2μF),精度±10%(代码“K”),满足大多数滤波、耦合电路的误差要求;
  2. 额定电压:直流额定电压16V,适用于3.3V/5V低压电源系统,避免过压击穿风险;
  3. 温度特性:采用X7R陶瓷介质,温度范围覆盖**-55℃~+125℃**,容值变化率≤±15%,宽温环境下性能稳定;
  4. 损耗特性:1kHz/25℃条件下,典型损耗角正切(tanδ)≤2.5%,低损耗可减少电路发热,提升效率。

三、封装与物理特性

  1. 封装规格:采用0805英制封装(对应公制2012,即2.0mm×1.2mm),是中小功率设备的常用表面贴装封装,兼顾体积与焊接可靠性;
  2. 尺寸细节:三星官方规格显示,封装高度约0.85mm,引脚间距0.5mm,适配标准回流焊工艺,可兼容多数PCB布线密度;
  3. 环保认证:符合RoHS 2.0、REACH标准,无铅无卤,满足全球电子市场环保要求。

四、X7R介质的性能优势

X7R是MLCC中应用最广泛的介质之一,CL21B225KOFVPNE的介质特性带来3个核心优势:

  1. 宽温稳定性:对比NPO(温度零漂移但容值偏小),X7R在-55~125℃范围内容值波动可控,适合户外设备、工业高温环境;
  2. 容值密度平衡:比Y5V温漂小(Y5V容值变化可达-82%~+22%),同时比NPO更容易实现2.2μF中等容值,适配“滤波+耦合”复合需求;
  3. 抗直流偏置:额定电压内,直流偏置对容值影响较小(典型偏置下容值下降≤10%),适合电源滤波电路。

五、典型应用场景

该型号因参数匹配度高,在多个领域有成熟应用:

  1. 消费电子:手机主板DC-DC转换滤波、蓝牙耳机音频耦合、智能手表传感器供电滤波;
  2. 工业控制:小型PLC输入输出接口滤波、电机驱动模块辅助电源滤波;
  3. 汽车电子:车载中控低功耗模块(蓝牙/USB)滤波、倒车雷达信号耦合(部分CL21B型号满足AEC-Q200汽车级要求);
  4. 通信设备:小型基站射频前端滤波、路由器电源模块滤波。

六、可靠性与品质保障

三星作为MLCC主流供应商,CL21B系列可靠性经过严格验证:

  1. 测试标准:通过高温寿命测试(125℃/1000h,容值变化≤±10%)、温度循环测试(-55~125℃,1000次循环)、湿度测试(85℃/85%RH,500h);
  2. 一致性:自动化生产工艺确保批量产品参数一致,减少电路调试难度;
  3. 供应链保障:全球供应链稳定,可满足中小批量到大规模生产的供货需求。

该型号凭借“小体积、宽温稳、成本优”的特点,成为电子设计中替代传统电解电容的常用选型,适配多场景下的滤波、耦合、旁路等功能需求。

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
