CL21Y105KCYVPNE 产品概述

一、产品概述

CL21Y105KCYVPNE 为 SAMSUNG(三星)生产的贴片多层陶瓷电容(MLCC),标称电容值 1.0 µF,容差 ±10%(K),额定电压 100 V,介质为 X7S,封装为 0805(公制 2012,约 2.0 mm × 1.25 mm)。此型号在体积与电容量之间取得平衡,适用于对体积、耐压与频率特性有综合要求的中高电压电路应用。

二、主要参数

  • 电容:1.0 µF
  • 容差:±10%(K)
  • 额定电压:100 V DC
  • 介质:X7S(Class II)
  • 封装:0805(2012,约 2.0 × 1.25 mm)
  • 品牌:SAMSUNG(三星)

三、电气与热性能特性

  • 温度特性:X7S 系列介质设计用于较宽温度范围下工作,通常覆盖约 −55 ℃ 至 +125 ℃。相较于 NP0/C0G(温度系数极小),X7S 属于介电常数较高的 Class II,体积效率好,但随温度与偏压会有一定的电容变化。
  • 频率特性:MLCC 固有低等效串联电阻(ESR)与低等效串联电感(ESL),在高频去耦与滤波场合表现优良。
  • DC 偏压效应:Class II 陶瓷在施加直流电压时会发生显著的电容衰减,尤其在额定电压靠近上限时更明显。1 µF 在 100 V 工况下的实际有效电容可能显著低于静态标称值,建议查阅厂商 DC-bias 曲线或在目标电压下进行实际测量。
  • 寿命与稳定性:陶瓷电容一般无极性、寿命长、抗高频脉冲能力好;但对机械应力和温度循环较敏感,封装尺寸与端接工艺直接影响可靠性。

四、典型应用场景

  • 高压电源去耦与旁路:适合 48 V、72 V 等中高压轨道以及需要 100 V 等级余量的电源滤波。
  • 开关电源输入/输出滤波与稳定回路:用于抑制高频干扰、降低纹波与提供快速瞬态电流。
  • 工业与通信设备:体积受限但需要较高耐压的滤波和旁路场合。
  • 模拟电路与功率模块中的局部旁路(非精密时间基准场合,不建议用于对容值精度极高的定时/谐振电路)。

五、封装、焊接与可靠性建议

  • 0805 尺寸便于自动贴片和大批量装配,适合表面贴装工艺(SMT)。
  • 推荐按 JEDEC / IPC 的回流焊曲线进行焊接,避免过高峰温与过长高温保温时间。
  • 注意焊接应力与基板翘曲,陶瓷电容对弯曲应力敏感,焊盘布局与阻焊设计应尽量减小端面应力集中,必要时加入挡胶或合理设计丝印/支撑。
  • 存储与湿敏:遵循厂商的烘干与 MSL(湿敏等级)要求,必要时进行返焊前烘烤以防止吸湿导致的焊接裂纹。

六、设计注意事项与建议

  • DC-bias 验证:在最终电路中务必测量实际工作电压下的电容值,以评估是否满足去耦/滤波需求;若在高电压下电容衰减过大,考虑并联多个电容或选用介电损失更小的器件(更大尺寸或不同介质)。
  • 容差与温漂:±10% 的静态容差配合 X7S 的温度特性,适合对精度要求不苛刻的旁路与滤波应用。对精密计时、频率确定电路,应优先考虑 NP0/C0G 类器件。
  • 并联与分层去耦:在电源设计中可与低值、高频性能更好的 MLCC(例如 0.1 µF 或 0.01 µF)并联,覆盖更宽的频率响应,提升瞬态响应能力。
  • 可靠性评估:用于汽车、工业高可靠场合时,应配合温度循环、机械冲击与长期老化试验,关注贴片断裂与容量漂移。

总结:CL21Y105KCYVPNE(SAMSUNG,0805,1 µF,±10%,100 V,X7S)在体积受限且需要较高耐压的去耦与滤波场合具有良好性价比。但因 X7S 及 Class II 陶瓷在温度和直流偏压下的容量变化特性,设计时应进行 DC-bias 与温度下的实际验证,并根据需要采取并联、容量保留或更改介质方案以满足系统要求。若需更详细的电压偏置曲线、温度曲线或封装外形尺寸与回流焊工艺参数,建议参考三星官方数据手册或联系经销商获取完整资料。

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.
