三星CL31B105KAHNNNE多层陶瓷贴片电容(MLCC)产品概述

一、产品基本参数与型号解析

三星CL31B105KAHNNNE是一款通用型多层陶瓷贴片电容(MLCC),核心参数与型号标识对应关系明确:

  • 容值:1μF(型号中“105”表示10×10⁵ pF);
  • 精度:±10%(型号中“K”为精度代码);
  • 额定电压:25V(型号前缀“CL31B”中“B”对应25V电压等级);
  • 温度系数:X7R(工业级宽温特性);
  • 封装:1206(英制)/3216(公制,3.2mm×1.6mm);
  • 品牌:三星(Samsung),属于其CL31系列通用MLCC产品线。

二、核心技术特性

该产品基于三星成熟的MLCC制造工艺,核心特性聚焦宽温稳定性、高可靠性与高频适配性:

  1. X7R温度特性:工作温度范围为-55℃至+125℃,电容变化率≤±15%(远优于Y5V介质的-80%~+20%),适合多数工业、消费电子的宽温场景;
  2. 多层陶瓷结构:通过堆叠钛酸钡基陶瓷介质与镍电极层,实现“高容值/体积比”,无极性设计支持双向安装,适配自动化贴装;
  3. 低寄生参数:典型ESR(等效串联电阻)≤10mΩ(1kHz下),ESL(等效串联电感)≤1nH,高频下仍能保持稳定滤波性能;
  4. 抗老化性能:采用无铅无卤电极与介质材料,经1000小时高温存储测试(125℃)后,容值变化≤±5%,可靠性符合工业级标准。

三、典型应用场景

CL31B105KAHNNNE的参数平衡了成本与性能,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑、笔记本电脑的电源滤波/去耦(如CPU供电路径抑制纹波)、信号耦合(音频、射频模块);
  2. 通信设备:路由器、交换机、基站的射频前端滤波、电源管理单元(PMU)辅助去耦;
  3. 工业控制:PLC(可编程逻辑控制器)、变频器的信号调理电路、电源模块滤波;
  4. 汽车电子(通用级):车载中控、音响系统的辅助信号电路(非安全关键件),适配-40℃至+85℃的车载环境。

四、封装与物理规格

  1. 封装尺寸:英制1206(0.12英寸×0.06英寸)=公制3216(3.2mm±0.2mm×1.6mm±0.15mm);
  2. 厚度范围:典型值1.0mm±0.1mm(不同批次因介质层数略有差异,以官方 datasheet 为准);
  3. 焊接兼容性:适配标准贴片焊盘(推荐焊盘尺寸:长1.8mm±0.2mm,宽1.0mm±0.1mm),支持回流焊、波峰焊工艺,焊接不良率≤0.1%(三星内部测试数据)。

五、选型与应用优势

对比同参数竞品,该产品具备以下核心优势:

  1. 性能成本平衡:X7R介质比NP0(容值小、成本高)更适合大容值场景,比Y5V(温度稳定性差)更可靠,是“通用宽温应用”的最优解;
  2. 品牌一致性:三星作为全球MLCC前三大供应商,产品批量生产一致性好(同批次容值偏差≤±5%),避免量产时的性能波动;
  3. 安装灵活性:1206封装体积适中,既满足小型化需求(比0805封装大15%但容值覆盖更广),又降低了超小封装的焊接难度;
  4. 环保合规:符合RoHS 2.0、REACH指令,无铅无卤,适配全球绿色制造要求。

六、质量保障与认证

三星CL31系列产品通过多重可靠性测试与行业认证:

  • 体系认证:ISO 9001质量管理体系、IATF 16949汽车电子体系(部分批次);
  • 可靠性测试:高温存储(125℃×1000h)、温度循环(-55℃~+125℃×1000次)、湿度测试(85℃/85%RH×1000h)、焊接热冲击(260℃×10次);
  • 第三方认证:UL、VDE等安全认证,确保在各类电子设备中合规使用。

综上,三星CL31B105KAHNNNE是一款性价比突出的通用MLCC,适合对温度稳定性、可靠性有要求的消费电子、通信与工业领域,是量产电子设备的主流选型之一。

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
