三星CL31A226KQHNNNE MLCC产品概述

一、产品基本属性与封装定位

三星CL31A226KQHNNNE是一款多层陶瓷贴片电容(MLCC),属于三星电子商用级基础系列产品,封装规格为1206(英制120mil×60mil,公制3.2mm×1.6mm),适配表面贴装工艺(SMT),适合高密度PCB设计场景,可通过自动贴片机实现高效生产。

二、核心电气参数详解

1. 容值与精度

  • 标称容值:22μF(标识代码“226”,即22×10⁶ pF);
  • 精度等级:±10%(标识“K”),满足绝大多数通用电路对容值的偏差要求,无需额外高精度校准。

2. 额定电压与过压能力

  • 直流额定电压:6.3V(标识“Q”),适用于低压直流供电系统(如3.3V/5V电路);
  • 短期过压耐受:符合IEC 60384-14标准,可承受额定电压1.5倍(9.45V)的短期过压(持续时间≤1分钟),提升电路抗瞬态干扰能力。

3. 温度系数与工作范围

  • 温度系数:X5R(EIA标准),对应参数为:
    • 低温极限:-55℃;
    • 高温极限:+85℃;
    • 容值变化率:±15%(相对于25℃基准值);
  • 温度特性优势:在消费电子常见工作温度(0~40℃)下,容值变化仅约±5%,远优于Y5V等高容变系数电容,稳定性突出。

4. 高频特性参数

  • 等效串联电阻(ESR):1kHz下典型值≈10mΩ,适合100kHz以下频段滤波;
  • 等效串联电感(ESL):典型值≈0.5nH,降低高频信号的电感干扰。

三、温度稳定性与环境适应性

X5R温度系数是该产品的核心设计亮点:

  • 相比X7R(-55℃+125℃),X5R在中温范围(-55+85℃)容值波动更小,且成本更低;
  • 相比Y5V(+20℃~+85℃,容变±22%),温度覆盖范围更广、容值一致性更好;
  • 可适配户外物联网设备(-20+60℃)、车载低功耗模块(-40+85℃)等场景的温度要求。

四、品牌可靠性与环保标准

三星作为全球MLCC前三大供应商,该产品具备以下可靠性优势:

  • 工艺成熟:采用镍(Ni)基内部电极+镀锡(Sn)外部电极,叠层工艺一致性好;
  • 环保合规:符合RoHS 2.0(无铅、无镉、无汞)、REACH指令,满足全球市场准入要求;
  • 可靠性测试:通过三星内部HHT(高温高湿存储)、TC(温度循环)、SHT(耐焊接热)等测试,平均无故障时间(MTBF)>10⁶小时,适合对可靠性要求较高的领域。

五、典型应用场景

  1. 消费电子:智能手机/平板的电源滤波(BMS输出滤波、射频电路去耦)、智能手表的传感器耦合;
  2. 音频设备:蓝牙耳机、便携式音箱的音频信号耦合(22μF适配10Hz~20kHz频段需求);
  3. 物联网设备:传感器节点(温湿度/加速度传感器)的电源滤波与信号耦合;
  4. 小型电源:5V/1A DC-DC转换器的输出滤波,提升纹波抑制比(典型值≈60dB@1kHz)。

六、选型与替代参考

  • 升级选型:若需更高温度(+125℃),可选择三星CL31B系列(X7R);若需更高电压(10V),可替换为CL31A226KQYNNNE;
  • 兼容替代:其他品牌1206封装22μF±10%6.3V X5R MLCC(如村田GRM188R61C226K)可兼容,但三星CL31A系列一致性更好、成本更具优势。

该产品凭借小封装、稳定温度特性、高可靠性,成为低压通用电路的主流选型之一,覆盖消费电子、物联网等多领域应用需求。

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
