三星CL32A476KOJNNNE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CL32A476KOJNNNE是一款通用型多层陶瓷贴片电容(MLCC),隶属于三星CL系列标准品,专为中容值、中电压的滤波、耦合、旁路等基础电路场景设计,适配消费电子、工业控制、通信设备等多领域的量产需求。其型号命名遵循行业规则:

  • CL:三星MLCC系列标识;
  • 32:封装公制代码(对应1210英寸封装);
  • A:容值/电压组合标识;
  • 476:容值代码(47×10⁶pF=47μF);
  • KOJ:K为精度±10%、OJ为直流额定电压16V;
  • NNNE:三星内部封装与包装标识。

二、关键电气性能参数

该产品核心电气指标明确且符合行业规范,具体如下:

  1. 容值与精度:标称容值47μF,精度±10%(K档),满足多数电子设备对容值误差的基本要求(无需高精度但需稳定容值的场景);
  2. 额定电压:直流额定电压16V,可承受1.5倍额定电压的短时过压(符合三星可靠性标准),避免电路瞬态电压冲击损坏;
  3. 损耗与ESR:1kHz、25℃条件下,损耗角正切值(tanδ)≤5%,等效串联电阻(ESR)约10mΩ级别,适合低损耗电源滤波场景;
  4. 容值温度漂移:X5R温度系数下,全温区容值变化≤±15%(优于行业标准)。

三、封装与物理特性

采用1210英寸封装(公制3225),是贴片电容中常用的中尺寸封装,物理参数适配多数PCB设计:

  • 外形尺寸:长3.2mm±0.2mm,宽2.5mm±0.2mm,厚度(含电极)约1.6mm±0.1mm;
  • 贴装兼容性:表面贴装设计,支持回流焊、波峰焊工艺(需遵循三星推荐温度曲线),引脚间距1.27mm,便于自动化SMT作业;
  • 包装形式:编带包装(1000pcs/盘),适配产线批量生产,减少人工分拣成本。

四、温度特性与稳定性

搭载X5R温度系数,是平衡容值与温度稳定性的主流选择,具体特性:

  • 工作温度范围:-55℃至+85℃,覆盖室内(040℃)、户外(-2060℃)及部分工业环境;
  • 容值稳定性:全温区容值变化≤±15%,避免温度波动导致电路性能波动;
  • 对比说明:相比C0G(NP0)容值稳定性(±0.05%),X5R容值更大但成本更低;相比X7R(-55~125℃),X5R温度范围 narrower,适合温度要求不极端的场景。

五、典型应用场景

因参数适配性强,该产品广泛应用于以下领域:

  1. 消费电子:手机、平板、笔记本的电源滤波(DC-DC转换电路)、音频信号耦合;
  2. 通信设备:路由器、交换机的电源旁路(抑制EMI)、射频信号滤波;
  3. 工业控制:小型PLC、传感器模块的电源稳压滤波、数字信号耦合;
  4. 家电产品:电视、空调、洗衣机控制板的电源电路、驱动电路滤波。

六、品牌与可靠性背书

三星作为全球MLCC头部供应商(市场份额稳居前三),该产品具备可靠品质:

  • 环保合规:符合RoHS 2.0、REACH标准,无铅无镉,适配全球市场;
  • 一致性优异:采用先进叠层工艺,批量产品参数偏差极小,减少产线不良率;
  • 可靠性测试:通过高温存储、温度循环、湿度测试等验证,MTBF达10⁶小时以上,满足量产设备长期稳定需求。

七、选型参考与注意事项

  1. 电压升级:若需25V额定电压,可切换至同参数25V版本(型号中OJ换为NJ);
  2. 宽温需求:若需-55~125℃,建议选X7R温度系数的CL32A476KRNCNNE;
  3. 封装缩小:若PCB空间紧张,1210可替换为0805封装,但需注意0805封装47μF16V MLCC容值稳定性稍弱;
  4. 降额设计:高电压/高温度场景建议采用1.2倍额定电压降额,延长产品寿命。

该产品凭借稳定的电气性能、可靠的品牌背书及广泛的适配性,成为电子设备量产中高频选用的MLCC之一。

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
