CL31Y225KCHVPNE 产品概述

一、产品简介

CL31Y225KCHVPNE 为 SAMSUNG(三星)出品的一款贴片多层陶瓷电容(MLCC),标称容量 2.2 μF,精度 ±10%,额定电压 100 V,介质为 X7S,封装 1206(英制),适用于对体积、耐压和温度性能有中等稳定性要求的电源滤波与能量缓冲场合。

二、主要参数与材料特性

  • 容值:2.2 μF ±10%
  • 额定电压:100 V DC
  • 介质:X7S(属 Class II,高介电常数材料)
  • 温度范围:典型工作温度覆盖 −55 ℃ 至 +125 ℃(具体请参照厂方数据表)
  • 封装:1206(约 3.2 mm × 1.6 mm)表面贴装

X7S 介质相较于 C0G/NP0 有更高的体积效率(单位体积容值更大),但属于非线性陶瓷,存在温度随动、老化和直流偏压时电容量下降等特性,需要在设计中予以考虑。

三、性能要点与使用注意

  • 直流偏压效应:在靠近额定电压工作时,电容实际可用容量会明显低于室温无偏压测量值,建议在关键电源回路做 DC-bias 测试并预留裕量。
  • 温漂与老化:X7S 在温度变化与长期使用中会产生可测老化效应(容值随时间呈对数下降),可通过选型冗余或周期性校准弥补。
  • 机械与焊接应力:MLCC 对焊接热冲击与 PCB 弯曲敏感,设计锡盘/焊膏与回流曲线时应遵循制造商推荐以降低裂纹风险。
  • 极性:陶瓷电容无极性,可任意方向安装。
  • ESR/ESL:本类陶瓷电容 ESR 与 ESL 通常较低,适合高频去耦与瞬态供应,但具体数值请参见数据表以评估纹波与发热。

四、典型应用场景

  • 高压 DC-DC 输出滤波与旁路
  • 工业电源与测控设备中的能量缓冲
  • 高频开关电源的去耦与吸收器(需注意 DC-bias 后有效容量)
  • 医疗、通信与仪器设备中的局部滤波(如需车规级认证请核实型号是否满足 AEC‑Q200 等标准)

五、选型与布局建议

  • 若电路常在接近 100 V 的偏压下工作,应考虑采用更高额定电压或并联多只电容分担偏压引起的容量损失。
  • 将 MLCC 靠近电源引脚放置、走短粗的过孔与铜箔,减少走线电感;必要时并联低阻抗片式电阻或非极性铝电解/薄膜电容以补偿直流偏压和低频容值。
  • 遵循厂方推荐的焊盘尺寸与回流焊曲线,使用合理的应力释放设计(如在器件两侧减少过长铜焊盘延伸)以降低机械破裂风险。
  • 采购时关注批次、湿度密封状态与出厂检验报告,存储遵循干燥包装规定。

六、测试与可靠性验证

建议对关键设计进行以下验证:实装后在工作电压下测量有效容值(DC-bias 下)、等效串联电阻(ESR/tanδ)、漏电流/绝缘电阻及高低温循环测试。对可靠性要求高的应用,向供应商索取完整的数据手册、可靠性测试记录与焊接工艺参数。

总结:CL31Y225KCHVPNE 在体积与额定电压之间提供较高的容值密度,适用于对中高压滤波和去耦有需求的产品,但在使用时需重点考虑 X7S 的 DC-bias、温漂与老化特性,合理预留裕量并按厂方工艺指导进行 PCB 布局与回流焊接。若需更严格的温度稳定性或更小的偏压衰减,建议评估其它介质或更高额定电压的备选件,并参考原厂完整数据表以完成最终验证。

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.
