三星CL21B474KBFVPNE 贴片陶瓷电容(MLCC)产品概述

一、核心参数与型号解读

三星CL21B474KBFVPNE属于多层陶瓷贴片电容(MLCC),型号各部分明确对应产品关键特性:

  • 前缀「CL21」:三星常规中容量MLCC系列标识,适配多数通用电路场景;
  • 「474」:容值编码,代表47×10⁴pF=470nF(470000pF);
  • 「K」:容差标识,对应**±10%**精度;
  • 额定电压:50V直流(DC),满足中低压电路供电需求;
  • 温度系数:X7R,是MLCC中温度稳定性较好的材质之一;
  • 封装:0805(英制尺寸),适配高密度PCB设计。

核心参数总结:容值470nF、精度±10%、额定电压50V、温度范围-55℃~+125℃、封装0805。

二、封装与尺寸规格

该电容采用0805英制贴片封装,公制尺寸约为2.03mm(长)×1.27mm(宽)×1.2mm(高)(典型值),无引线结构设计,完全适配表面贴装工艺(SMT)。

0805封装的优势在于:

  • 尺寸紧凑,可有效节省PCB布局空间,适合消费电子、工业控制等小型化设备;
  • 贴装兼容性强,支持自动贴片机高速生产,降低人工成本;
  • 机械强度稳定,能承受常规PCB弯曲和振动环境。

三、电性能与温度特性

3.1 电性能参数

  • 额定电压:50V DC,实际工作电压建议降额至40V以内(降额80%),可显著延长产品寿命;
  • 容值精度:±10%,覆盖一般滤波、耦合、旁路等应用的精度需求,无需额外校准;
  • 绝缘电阻:常温(25℃)下≥10⁹Ω,确保电路无漏电流干扰;
  • 损耗角正切(tanδ):典型值≤0.02(1kHz下),低频损耗低,适合信号传输场景。

3.2 温度特性(X7R材质)

X7R是MLCC常用的温度稳定型材质,核心特性:

  • 工作温度范围:-55℃~+125℃,适配工业级、车载级(部分场景)宽温环境;
  • 容值变化率:在全温度范围内≤±15%,远优于Y5V等低价材质,避免温度波动导致容值漂移。

四、典型应用场景

结合参数与特性,该电容主要适配以下场景:

  1. 电源滤波:DC-DC转换器输出滤波、线性电源稳压后滤波,滤除电源纹波;
  2. 信号耦合:音频电路(如耳机接口、功放)、低频信号链路(≤100kHz)的耦合电容;
  3. 旁路电容:数字电路(MCU、FPGA、DSP周边)的电源旁路,滤除高频噪声(10kHz~100MHz);
  4. 工业控制电路:PLC、传感器模块的电源与信号滤波,适配-40℃~+85℃工业环境;
  5. 消费电子:手机、平板、智能家居设备的电源管理模块(PMIC)周边电容,满足小型化需求。

五、可靠性与品牌优势

5.1 可靠性测试

三星CL21系列电容经过严格可靠性验证,符合国际标准:

  • 高温负载寿命:125℃、50V、1000小时后,容值变化≤±10%,绝缘电阻≥10⁸Ω;
  • 湿度温度循环:85℃/85%RH、50V、500小时后,性能无明显衰减;
  • 机械振动测试:10~2000Hz、加速度2g,振动后电性能稳定。

5.2 品牌优势

三星作为全球MLCC前三供应商,具备:

  • 产能稳定:全球多条生产线保障供货,减少生产断供风险;
  • 质量一致性:采用自动化生产工艺,每批次产品参数偏差极小;
  • 技术支持:提供完整的 datasheet 与应用指导,助力电路设计优化。

六、选型与使用注意事项

  1. 电压降额:实际工作电压≤40V(额定电压80%),避免过压损坏;
  2. 温度限制:禁止超过-55℃~+125℃工作范围,防止容值漂移或失效;
  3. 焊接工艺:回流焊峰值温度≤245℃,焊接时间≤10秒,避免过热开裂;
  4. 容值匹配:470nF适合低频滤波,高频场景可搭配10nF~100nF电容组合使用;
  5. 包装方式:料号后缀「VPNE」对应卷带包装(Tape&Reel),每卷3000pcs,适配自动贴装。

该产品凭借稳定的电性能、宽温适应性与高可靠性,成为通用电路设计中电源滤波、信号耦合的优选元件。

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
