CL21B105KBFVPJE 三星贴片陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

CL21B105KBFVPJE是三星电子CL21系列中的通用型多层陶瓷贴片电容(MLCC),针对中低电压、中等容值场景设计,兼具温度稳定性与成本优势,是消费电子、通信、工业控制等领域的主流选型之一。其型号命名遵循三星MLCC标准编码逻辑,可直观解析核心参数(后文将详细说明)。

二、关键技术参数解析

该产品核心参数完全匹配通用电路设计需求,具体如下:

  1. 容值与精度:标称容值1μF(型号中“105”代表10×10⁵ pF),精度等级±10%(“K”为EIA精度代码),满足大多数滤波、耦合场景的误差要求,无需高精度场景的额外成本。
  2. 额定电压:50V DC(“B”为三星电压代码,对应50V额定值),适用于低压直流电路;若用于交流电路,需按额定电压的70%降额使用(如AC35V以下)。
  3. 温度特性:采用X7R陶瓷介质,符合EIA标准:工作温度范围-55℃+125℃,容值变化≤±15%——相比Y5V材质(容值变化±20%80%)稳定性更强,适配环境温度波动较大的场景。

三、封装与物理特性

  1. 封装规格:0805英制封装(公制2012),尺寸约2.0mm×1.25mm×1.0mm(厚度因容值略有差异),属于小型化贴片封装,适配高密度PCB设计,兼容主流SMT贴装设备(贴装精度要求≥±0.1mm)。
  2. 电极设计:两端镍锡镀层电极,焊盘匹配标准0805焊盘(宽度0.60.8mm,长度1.51.8mm),确保焊接可靠性;无极性设计,贴装方向不影响性能。

四、材料特性与性能表现

  1. 陶瓷介质优势:X7R材质平衡了容值密度与温度稳定性——相比NP0材质(高频稳定但容值低),1μF级容值更易实现;相比Y5V材质(容值高但温漂大),更适合对容值稳定性有要求的电路。
  2. 损耗与频率特性:1kHz~1MHz频率范围内损耗低(DF值≤2%),适合电源滤波、信号耦合;高频(>10MHz)下容值略有下降(约10%),需根据实际频率调整选型。
  3. 耐环境性能:通过温度循环(-55℃~+125℃,1000次)、湿度老化(85℃/85%RH,1000h)等测试,长期使用可靠性高。

五、典型应用场景

  1. 消费电子:智能手机、平板的DC-DC转换输出滤波、音频电路耦合,笔记本电脑的主板电源滤波。
  2. 通信设备:路由器、交换机的电源模块滤波,中频信号路径的耦合电容。
  3. 工业控制:小型PLC、传感器模块的电源滤波与信号调理,适配工业环境的温度变化(-40℃~+85℃常见场景)。
  4. 汽车电子(衍生型号):若为AEC-Q200认证版本(如CL21B105KBFVPJE-A),可用于车载娱乐系统、车身控制模块的低压电路(需确认具体型号的汽车级认证)。

六、可靠性与品质保障

  1. 三星品质体系:符合ISO 9001、ISO 14001认证,产品经过振动测试(10~2000Hz,1.5g)、冲击测试(1000g/1ms),失效率≤1 FIT(1 FIT=10⁻⁹次失效/小时)。
  2. 焊接可靠性:无铅镀层适配回流焊(峰值温度245℃±5℃)、波峰焊(峰值温度260℃±5℃),焊接后抗剥离强度≥2N,长期使用不易出现虚焊、脱焊。
  3. 寿命预期:在额定电压(50V DC)与温度(≤125℃)下,平均寿命≥10⁶小时,满足大多数电子设备的使用寿命要求(如消费电子3~5年、工业设备10年)。

七、选型与替换注意事项

  1. 替换原则:需匹配容值、精度、电压、温度系数、封装,例如村田GRM188R61C105KA73D(1μF/50V/X7R/0805)可直接替换。
  2. 降额使用:直流电压建议降额至40V以下,交流电压降额至25V以下,可显著延长寿命。
  3. 高频场景注意:若应用频率>10MHz,建议选用高频特性更好的NP0材质电容(如三星CL05B105KB5NNNC),避免容值偏移影响性能。

CL21B105KBFVPJE凭借稳定的性能、合理的成本与广泛的兼容性,成为电子设计中1μF/50V级电容的主流选择,适用于绝大多数通用电路场景。

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.
