CL31B225KAHNNNE 三星贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

CL31B225KAHNNNE是三星电子推出的通用型贴片多层陶瓷电容(MLCC),属于工业级与消费级电子设备的常用被动元件。该型号聚焦低压电路的滤波、耦合、旁路等基础功能,凭借稳定的电性能、成熟的封装工艺及可靠的品牌背书,广泛应用于通信、消费电子、工业控制等领域,是替代低精度Y5V电容、适配宽温场景的优选型号。

二、关键技术参数详解

该型号的核心电性能参数明确且适配多数低压场景,关键参数如下:

  • 容值与精度:标称容值2.2μF(即2250nF),精度等级为**±10%(K档)**——既满足多数电路对容值的基本需求,又比高精度(±5%)型号成本更具优势,适合对容值偏差不敏感的滤波、耦合电路(如电源滤波、音频耦合)。
  • 额定电压:25V直流(DC)——覆盖常见低压电路(如12V车载、5V消费电子)的工作电压范围,留有余量(通常需选额定电压≥1.5倍工作电压)保障长期可靠性。
  • 温度系数:X7R——铁电陶瓷介质的典型温度特性,容值在-55℃至+125℃范围内变化不超过±15%,远优于Y5V等低成本介质,可满足车载、工业控制等宽温环境需求。

三、封装与物理特性

采用1206贴片封装(英制尺寸0.12英寸×0.06英寸,公制对应3.2mm×1.6mm),是电子行业最常用的小型封装之一,具体物理特性如下:

  • 标准尺寸:长3.2±0.2mm、宽1.6±0.2mm、典型厚度1.0mm(部分批次为1.6mm,需参考官方datasheet确认);
  • 引脚间距:0.5mm,兼容主流自动贴片机(SMT)生产,支持高速贴片工艺(速度可达10万点/小时以上);
  • 焊盘设计:符合IPC-A-610标准,适配无铅回流焊工艺(推荐温度曲线:预热150-180℃/60-120s,回流220-245℃/30-60s),焊接可靠性高。

四、材料特性与环境适应性

X7R介质材料是该型号的核心优势之一,相比其他介质具备明显平衡优势:

  • 温度稳定性:相比NP0(零温度系数),X7R容值更大、成本更低;相比Y5V,温度漂移更小(±15% vs ±20%以上),可稳定工作于-55℃至+125℃的宽温范围;
  • 容值密度:多层陶瓷叠层结构实现高容值小型化,2.2μF容值在1206封装内稳定实现,无需牺牲尺寸即可满足电路需求;
  • 环保合规:符合RoHS 2.0、REACH(SVHC)等全球环保标准,无铅无卤,适配绿色电子产品设计(如欧盟CE认证产品)。

五、典型应用场景

该型号因参数均衡,适用于多领域的基础电路,核心应用场景包括:

  1. 消费电子:智能手机/平板的DC-DC电源滤波(如5V转3.3V模块输出)、音频耦合(耳机接口、扬声器驱动电路)、射频电路旁路;
  2. 工业控制:PLC(可编程逻辑控制器)的信号耦合、传感器接口滤波(如温度传感器、压力传感器的信号调理);
  3. 汽车电子:车载信息娱乐系统(IVI)、仪表盘的低压电路滤波(适配12V车载电源,满足-40℃~+85℃的车载环境);
  4. 通信设备:路由器、交换机的电源滤波、以太网接口耦合(10/100M以太网物理层电路);
  5. 家电产品:智能电视、变频空调控制板的滤波与耦合电路(如MCU电源滤波、按键信号耦合)。

六、品牌与可靠性优势

三星作为全球MLCC主要供应商(市占率超20%),该型号具备以下可靠性优势:

  • 工艺成熟:采用高精度陶瓷叠层(层数可达100层以上)、银钯电极印刷工艺,容值一致性偏差≤3%(批量生产);
  • 可靠性测试:经过高温老化(125℃/1000h,容值变化≤5%)、湿度循环(85℃/85%RH/1000h,绝缘电阻≥10^9Ω)、机械振动(10-2000Hz/1.5G,无开路短路)等测试,MTBF(平均无故障时间)超10^6小时;
  • 供应链稳定:全球生产布局(韩国、中国苏州、越南等),月产能超10亿只,交期可控(标准交期2-4周),适合批量采购需求。

七、选型与替换参考

若需替换或选型,可参考以下要点:

  • 替换型号:同参数的村田GRM188R61C225KA73D(1206、25V、2.2μF、X7R、±10%)、TDK C1206X7R225KAT2R(封装、参数完全匹配);
  • 选型注意:需确认电路最大工作电压(需低于25V)、环境温度范围(需覆盖-55℃~+125℃),封装需匹配PCB设计(1206封装的焊盘尺寸通常为1.8mm×1.2mm)。

该型号凭借参数均衡、可靠性高、成本可控的特点,成为电子设计中低压宽温场景的经典选型,适合各类量产电子产品的成本优化与性能平衡需求。

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.
