CL21B104KCFNNNE 贴片多层陶瓷电容(MLCC)产品概述

一、产品身份与型号对应关系

CL21B104KCFNNNE是三星电子(SAMSUNG) 推出的0805封装X7R系列通用型贴片多层陶瓷电容(MLCC),型号命名直接映射核心参数:

  • CL21:三星通用MLCC基础系列标识;
  • B:封装类型(对应英制0805,公制2012);
  • 104:容值编码(10×10⁴pF=100nF);
  • K:容值精度(±10%);
  • 后缀CFNNNE:明确额定电压(100V DC)、温度特性(X7R)及生产批次信息。

该型号属于工业级标准品,覆盖中低压电路的滤波、耦合与去耦场景,是量产电路的优选元件。

二、核心技术参数深度解析

2.1 容值与精度

容值为100nF(10⁻⁷F),精度±10%(K档)——既无需C0G系列的超精密成本,又避免Y系列(如Y5V)容值随温度/电压剧烈变化的问题。实际应用中,±10%的偏差可通过“多电容并联”进一步优化,满足90%以上通用电路的匹配需求。

2.2 额定电压与温度特性

  • 额定电压:100V DC,适配24V/48V工业电源、12V通信电源的高压侧,比63V电容覆盖场景更广;
  • 温度系数:X7R,定义为-55℃+125℃范围内,容值变化≤±15%。这一特性使其能适应工业现场极端温度(如北方户外控制柜低温、南方车间高温),远优于Y系列(容值变化可达-82%+22%)。

2.3 电气性能补充

  • 漏电流:典型值≤10μA(25℃、100V DC下),长期使用无明显老化;
  • 损耗因子(DF):典型值≤2%(1kHz、25℃),适合低噪声信号耦合与滤波。

三、封装与物理特性

采用0805英制封装(公制2012),尺寸为2.0mm(长)×1.2mm(宽)×0.8mm(典型厚度),符合IPC-A-610标准:

  • 焊盘设计:标准0805焊盘(0.8mm×0.6mm),兼容西门子、富士等主流SMT贴片机,焊接合格率≥99.5%;
  • 电极镀层:镍-锡(Ni-Sn),耐多次回流焊(≤3次),无镀层脱落风险;
  • 重量:约0.02g/只,适合服务器主板、工业控制板等高密度PCB设计。

四、典型应用场景

CL21B104KCFNNNE的参数特性使其成为以下场景的核心元件:

4.1 工业控制领域

  • PLC(可编程逻辑控制器)电源输入滤波:过滤电网尖峰脉冲,保护CPU模块;
  • 变频器/伺服驱动器母线滤波:稳定直流电压,减少纹波对电机的干扰;
  • 传感器信号调理:耦合低噪声模拟信号,屏蔽电磁干扰。

4.2 电源系统设计

  • 开关电源(SMPS)输出滤波:配合电解电容形成“大容值+小容值”组合,抑制高频纹波;
  • UPS辅助电源滤波:确保电池切换时电压稳定;
  • LED驱动电源EMC滤波:满足GB 9254电磁兼容标准。

4.3 通信与消费电子

  • 基站RRU(射频拉远单元)信号去耦:减少电源噪声对射频信号的干扰;
  • 智能电视/变频空调电源模块:兼顾性能与成本,适配宽温环境。

注意:不适合超高频(>100MHz)电路(如射频振荡器)或超精密场景(如医疗传感器),此类场景建议选用C0G系列。

五、选型与使用注意事项

5.1 电压降额设计

实际工作电压建议不超过80V DC(额定电压的80%),避免长期过压导致陶瓷介质老化、容值下降。例如,若电路工作电压为72V,100V电容已满足余量要求。

5.2 温度与偏置效应

  • 工作温度上限为125℃,超过则容值变化超±15%,影响电路性能;
  • X7R存在直流偏置效应:偏置电压升高时容值下降(如100V电容在50V偏置下,容值约降15%),选型需预留余量。

5.3 焊接与存储

  • 焊接:采用回流焊,温度曲线符合IPC-J-STD-020(峰值245℃±5℃,时间≤10s),避免手工焊过热(>350℃)损坏介质;
  • 存储:常温干燥环境(25℃±5℃,湿度≤60%),开封后1个月内使用完毕;吸潮后需烘烤(120℃×24h)。

六、性能优势总结

CL21B104KCFNNNE作为三星成熟型号,核心优势显著:

  1. 宽温稳定:X7R介质适应-55~125℃极端环境,工业可靠性高;
  2. 电压覆盖广:100V额定电压满足中低压电源与工业控制主流需求;
  3. 尺寸紧凑:0805封装适配高密度PCB,节省空间;
  4. 成本可控:相比C0G系列,X7R介质成本更低,适合批量应用;
  5. 可靠性高:三星工艺成熟,漏电流低、损耗小,长期稳定性好。

该型号已通过RoHS、REACH等环保认证,符合全球电子行业合规要求,是工业、通信、消费电子领域的高性价比选择。

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.
