三星CL31A475KL9LNNC多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与定位

CL31A475KL9LNNC是三星电机(SAMSUNG ELECTRO-MECHANICS)推出的通用型多层陶瓷贴片电容(MLCC),属于三星CL系列中针对中容值、中等电压场景设计的主力型号。该型号以“均衡的容值-电压-温度特性”为核心优势,广泛适配消费电子、工业控制、通信设备等领域的电路滤波、耦合、旁路等基础功能需求,是电子设计中替代同类竞品的高性价比选择。

二、基础电气与标识参数

该型号的核心性能可通过型号编码快速解析,同时具备明确的量化指标:

  • 容值:4.7μF(型号中“475”为容值代码,代表47×10⁵ pF=4.7μF,需注意与“474=0.47μF”等代码区分);
  • 精度:±10%(型号中“K”为精度代码,对应JIS标准±10%,满足多数通用电路的精度要求);
  • 额定电压:35V DC(直流额定电压,交流场景需按1.414倍降额计算,如25V AC以下可稳定工作);
  • 温度系数:X5R(陶瓷材料温度特性代码,是该型号核心特性之一);
  • 封装标识:1206(英制封装尺寸,对应公制3.2mm×1.6mm)。

三、X5R陶瓷材料特性解析

X5R是MLCC中通用型温度稳定材料,其性能严格符合EIA标准:

  • 温度范围:-55℃(下限)至+85℃(上限),覆盖绝大多数消费电子、工业设备的工作环境;
  • 容值稳定性:在上述温度范围内,容值相对于25℃基准值的变化不超过±15%,优于Y5V等高容值材料的温度漂移(Y5V通常±22%);
  • 材料优势:相比NPO(COG)等低温系数材料(容值密度低),X5R可在1206封装下实现4.7μF的中容值,兼顾了容值密度与温度稳定性。

四、1206封装尺寸与物理规格

1206是贴片元件中中号通用封装,CL31A475KL9LNNC的具体物理参数如下:

  • 核心尺寸:长3.20±0.20mm,宽1.60±0.15mm(英制0.12英寸×0.06英寸);
  • 典型厚度:0.80±0.10mm(部分批次因生产工艺略有差异,需以原厂datasheet为准);
  • 端电极设计:采用无铅锡膏(Sn/Ag/Cu),符合RoHS 2.0及REACH环保标准,适配回流焊(峰值260℃)、波峰焊等主流焊接工艺,焊接后无脱落、开裂风险。

五、典型应用场景

该型号因“均衡特性”,广泛应用于以下领域:

  1. 消费电子:智能手机/平板的电源管理模块(滤波、旁路)、音频电路(耦合)、摄像头模组供电;
  2. 工业控制:小型PLC、传感器节点的信号调理电路、低压电源滤波;
  3. 通信设备:小型基站、路由器的DC-DC转换模块滤波、射频前端旁路;
  4. 家电产品:智能电视、空调的控制板、电源单元(如开关电源输出滤波);
  5. 汽车电子(商用级):车载娱乐系统、非安全关键部件(如车载充电器辅助电路)。

六、可靠性与环境适应性

三星CL系列MLCC具备成熟的可靠性表现,CL31A475KL9LNNC的关键指标包括:

  • 耐电压耐久性:额定35V DC下可长期稳定工作,短时间1.5倍过载(52.5V)无击穿;
  • 温湿度老化:在85℃/85%RH环境下,1000小时老化后容值变化≤±10%,ESR(等效串联电阻)无明显上升;
  • 机械可靠性:经振动(10-2000Hz,1.5g)、冲击(1000g,1ms)测试后,性能无衰减;
  • 环保合规:无铅、无卤,符合欧盟RoHS、中国RoHS及REACH SVHC要求,可用于出口产品。

七、品牌与供货保障

作为三星电机的主力型号,CL31A475KL9LNNC具备以下优势:

  • 原厂品质:三星电机是全球MLCC前三大供应商之一,生产工艺采用卷绕式多层陶瓷工艺,一致性好(同批次容值偏差≤±5%,优于标称±10%);
  • 供货稳定性:该型号为常规量产型号,市场库存充足,交货周期通常为2-4周(旺季略有延长);
  • 技术支持:原厂提供完整的datasheet、应用指南,以及焊接工艺优化建议,可通过三星电机官网或授权代理商获取。

该型号以“高性价比+均衡特性”成为电子设计中中容值MLCC的常用选择,尤其适合对温度稳定性有一定要求但无需极端精度的场景。

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.
