三星CL31B474KBHNNNE多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与定位

三星CL31B474KBHNNNE是一款通用型多层陶瓷贴片电容(MLCC),隶属于三星电子CL系列,针对中小功率电路的滤波、耦合、去耦等核心需求设计。该型号采用1206(英制)封装,兼容SMT自动化生产,是消费电子、工业控制等领域的主流选型之一,兼具性价比与可靠性。

二、基础电气性能参数

该型号的核心电气参数明确,可直接匹配多数通用电路需求:

  • 容值:470nF(即474pF,对应标识“474”),满足滤波电路对中等容值的需求;
  • 精度:±10%(行业标准“K”档),覆盖通用电路对容值偏差的容忍范围,无需额外高精度校准;
  • 额定电压:50V(直流额定值),交流应用需按峰峰值额外降额(通常为直流的70%左右);
  • 温度系数:X7R——温度特性定义为:工作温度范围**-55℃~+125℃**,此范围内容值变化≤±15%,平衡了容值稳定性与温度适应性,优于Y5V介质的容值漂移,适用于温度波动较大的场景。

三、关键材料与封装特性

3.1 介质与结构

采用X7R型陶瓷介质,通过多层陶瓷浆料与镍内电极交替叠压烧结而成,体积小、容值密度高,比传统电解电容更适合高密度PCB设计。

3.2 封装细节

  • 封装尺寸:1206(英制:长3.2mm×宽1.6mm,公制3216),符合IPC-7351封装标准,适配常规SMT贴装设备;
  • 端电极:镍(Ni)打底+锡(Sn)镀层,兼容无铅回流焊(峰值温度≤260℃),焊接后无虚焊、脱落风险;
  • 引脚间距:端电极中心间距约2.2mm,满足PCB布线间距要求。

四、典型应用场景

该型号覆盖多领域通用需求,核心应用包括:

  1. 消费电子:智能手机/平板的DC-DC转换电路输出滤波、音频模块耦合电容、显示屏背光驱动滤波;
  2. 工业控制:PLC(可编程逻辑控制器)的信号滤波、电机驱动电路的EMI抑制、传感器信号调理电路去耦;
  3. 通信设备:路由器/交换机的电源模块滤波、射频前端电路耦合电容;
  4. 小家电:智能空调、洗衣机控制板的电源滤波、MCU周边去耦。

五、可靠性与环境适应性

三星CL系列MLCC遵循严格的可靠性测试标准,该型号关键指标如下:

  • 寿命测试:50V直流+125℃环境下,1000小时后容值变化≤±10%,漏电流≤初始值的150%;
  • 焊接稳定性:经260℃无铅回流焊3次,无开裂、端电极脱落等失效;
  • 湿度适应性:85℃/85%RH高湿环境下测试1000小时,性能无明显衰减;
  • 机械可靠性:抗振动(10Hz2000Hz,10G加速度)、抗冲击(50G100G峰值),满足工业级机械环境需求。

六、选型匹配要点

  1. 电压降额:实际直流工作电压建议≤40V(额定电压的80%),避免长期过载;
  2. 温度扩展:若环境温度超出-55℃+125℃,需更换X8R(-55℃+150℃)型号;
  3. 精度升级:射频耦合等高精度场景需选择±5%或±1%精度的MLCC;
  4. 封装升级:更大容值(≥1μF)或更高电压(≥100V)需求需换1210或更大封装。

总结

三星CL31B474KBHNNNE凭借稳定的电气性能、可靠的封装设计及广泛的兼容性,成为消费电子、工业控制等领域的主流通用MLCC,可有效满足多数电路的滤波、耦合需求,是高性价比选型的典型代表。

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
