CL21B105KOFVPNE 陶瓷电容器产品概述

CL21B105KOFVPNE是三星(SAMSUNG)推出的通用型多层陶瓷电容器(MLCC),凭借稳定性能、紧凑封装及高可靠性,广泛适配消费电子、小型家电、工业控制等低电压场景。以下从多维度详细解析其核心信息。

一、产品基本定位与型号解析

该型号属于三星CL系列MLCC,针对低电压通用电路设计,无极性特性使其安装灵活。型号各部分含义明确:

  • CL21B:三星MLCC通用系列标识;
  • 105:容值编码(10×10⁵ pF = 1 µF);
  • K:精度等级(±10%);
  • OF:额定电压(16 V直流);
  • VPNE:封装及环保参数(0805封装、无铅、符合RoHS标准)。

二、核心性能参数详解

1. 容值与精度

额定容值1 µF,精度±10%,满足多数电路对容值偏差的要求,无需额外校准,适配滤波、耦合等基础功能。

2. 额定电压

直流额定电压16 V,适用于3.3 V、5 V等低电压系统(如电池供电回路),需遵循80%降额原则(实际工作电压≤12.8 V),避免老化失效。

3. 温度特性(X7R材质)

采用X7R介电材质,温度稳定性优于Y5V,符合行业标准:

  • 工作温度范围:-55℃ ~ +125℃;
  • 全温区容值变化率:±15%,适配宽温环境(如车载、工业现场)。

4. 其他关键特性

  • 无极性:双向接入电路,安装无方向限制;
  • 低ESR(等效串联电阻):高频响应较好,适合信号耦合;
  • 环保合规:无铅、无镉,符合RoHS及REACH标准。

三、封装与物理尺寸

采用0805封装(英制),对应公制尺寸为2012(长2.0 mm × 宽1.2 mm),典型厚度0.8 mm,适配PCB小型化设计,兼容回流焊、波峰焊工艺。

四、品牌与可靠性保障

三星作为全球MLCC头部供应商,CL21B系列通过多重可靠性测试:

  • 机械强度:抗弯折性能满足IEC 60384-1标准,避免焊接/安装开裂;
  • 耐湿测试:85℃/85%RH环境下1000小时,性能无明显衰减;
  • 寿命指标:额定条件下平均寿命超10⁶小时,长期可靠性高。

五、典型应用场景

结合性能参数,该电容适用于以下场景:

  1. 消费电子:手机、平板的电源滤波(电池回路)、音频耦合电路;
  2. 小型家电:遥控器、加湿器、LED小夜灯的控制电路滤波;
  3. 工业控制:低电压传感器、小型PLC的信号滤波;
  4. 通信设备:蓝牙模块、无线耳机的中频耦合电路。

六、选型与使用注意事项

  1. 电压降额:实际直流电压≤12.8 V,避免偏置电压导致容值下降;
  2. 机械应力:焊接时避免PCB过度弯折,安装后远离振动源(陶瓷电容易开裂);
  3. 温度适配:确保环境温度在-55℃~+125℃内,超出需换高温级产品;
  4. 偏置效应:X7R容值随直流偏置升高而下降(16 V偏置下约为额定值70%),选型需考虑实际偏置条件。

综上,CL21B105KOFVPNE是一款性价比高、可靠性强的通用MLCC,可满足多数低电压、小型化电路的滤波与耦合需求。

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
