CL21B225KOFNNNE 贴片多层陶瓷电容(MLCC)产品概述

一、核心电气参数

CL21B225KOFNNNE为三星CL21B系列通用型MLCC,核心参数精准适配多数低压电路需求:

  • 容值:2.2μF(标识代码“225”,即22×10⁵ pF),覆盖滤波、耦合等基础功能的容值需求;
  • 精度:±10%(标识代码“K”),属于通用精度等级,可满足非高精度场景(如电源滤波、普通信号处理);
  • 额定电压:16V DC,适用于低压电源(3.3V/5V系统)、信号电路,实际工作电压建议降额至12.8V以下延长寿命;
  • 温度系数:X7R(行业标准),工作温度范围-55℃~+125℃,此区间内电容值波动≤±15%,稳定性优于Y5V等经济型材质;
  • 无极性设计:无需区分安装方向,简化电路设计与生产流程。

二、封装与品牌背景

该型号采用0805封装(英制0.08″×0.05″,公制2012规格:2.0mm×1.2mm),是电子行业通用小型化封装,适配高密度PCB布局(如便携式设备、小型模块);
品牌为三星(SAMSUNG),作为全球MLCC核心供应商,CL21B系列经高温老化、湿度循环、机械冲击等严格测试,品质稳定且供货能力强,符合欧盟RoHS 2.0、REACH环保法规,无铅无卤。

三、关键性能特点

  1. 宽温稳定:X7R系数确保极端环境(工业高温、低温存储)下电容值波动小,避免电路性能漂移;
  2. 高可靠长寿命:多层陶瓷结构无电解液、无极性,耐电压冲击、机械振动能力强,典型寿命超10万小时;
  3. 小体积高密度:0805封装体积仅约2.4mm³(含焊盘),可缩小电路尺寸,适配智能手机、可穿戴设备;
  4. 电气兼容性强:16V额定电压覆盖多数低压系统,2.2μF容值适配电源滤波(DC-DC输出)、信号耦合(音频/射频);
  5. 环保合规:无铅电极与封装材料,满足绿色制造需求,可用于出口或认证项目。

四、典型应用场景

因参数均衡、性价比高,广泛应用于:

  1. 消费电子:智能手机、平板、智能手表的电源滤波(电池/USB接口)、音频耦合;
  2. 工业控制:PLC模块、传感器节点、小型电机驱动的信号处理与电源旁路;
  3. 通信设备:路由器、交换机、无线AP的射频滤波、电源稳压;
  4. 汽车电子(通用级):车载中控、倒车影像等非安全关键部件的低压电路;
  5. 电源模块:DC-DC转换器、AC-DC适配器的输出滤波,提升纹波抑制比。

五、选型与使用注意事项

  1. 电压降额:实际工作电压≤12.8V(额定80%),避免过压老化;
  2. 温度限制:工作温≤125℃,存储温-40℃~+85℃;
  3. 焊接工艺:推荐回流焊(峰值245±5℃,时间≤10秒),避免波峰焊;
  4. 机械应力:PCB弯曲度≤0.5%,防止电容开裂;
  5. 包装存储:卷带包装(后缀“F”),防潮存储(湿度≤60%),开封后12个月内使用。

该型号以稳定性能、小型化设计和高性价比,成为通用低压电路的优选MLCC之一。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
