CL10B105KB8NQNC 产品概述

一、产品简介

CL10B105KB8NQNC 是三星(SAMSUNG)生产的贴片多层陶瓷电容(MLCC),公称容量 1.0 μF,额定电压 50 V,温度特性为 X7R,尺寸为 0603(约 0.06"×0.03" / 1.6 mm × 0.8 mm)。该系列在体积、容量与电压间取得平衡,适合对体积敏感且需中等容值与较高耐压的电路应用。

二、主要规格

  • 容值:1.0 μF(105)
  • 初始容差:±10%(K)
  • 额定电压:50 V
  • 温度特性:X7R(-55 °C 至 +125 °C,典型温度漂移在规格范围内)
  • 封装:0603(SMD/贴片)
  • 品牌:SAMSUNG

三、电气性能与特性

  • X7R 介质属于二类陶瓷,具有较高电容密度与中等温度稳定性,适合旁路和去耦用途。按标准温度范围内容值变化在一定限度(典型按标准规格允许±15%随温度变化)。
  • 直流偏压依赖(DC bias):此类陶瓷随施加电压会出现容值下降,尤其在高电压下更明显。50 V 额定下工作时应参考厂商 DC-bias 曲线以确认实际有效容值。
  • 损耗与等效串联电阻(ESR)较低,响应速度快,适合高频旁路。但 X7R 的稳定性不及 NP0/C0G,不适用于高精度定时或参考回路。
  • 老化特性:二类陶瓷随时间会发生一定程度的慢衰(容值逐渐下降),在长期稳定性设计时需考虑。

四、安装与布局建议

  • 将 CL10B105KB8NQNC 靠近供电引脚或芯片电源引脚布局以最小化走线电感和串联阻抗。
  • 对于电源去耦,建议与更小容值的高频陶瓷并联(如 0603、0402 的 0.1 μF、0.01 μF)以覆盖更宽频带的噪声。
  • 对于有较高直流偏压的场合,应在设计时验证实际工作电压下的剩余容值,必要时考虑并联多个电容或选用更大尺寸/不同介质。
  • 采用标准回流焊工艺,遵循厂商推荐的焊盘与回流曲线可获得稳定焊接质量;避免在封装附近施加机械应力(如 PCB 弯曲)。

五、典型应用场景

  • MCU、电源管理芯片的去耦与旁路
  • 电源滤波、输入输出去耦
  • 模拟与混合信号电路的旁路(非精密定时场合)
  • 消费电子、通信设备、工业控制中对体积与耐压有要求的场合

六、选型注意事项

  • 若电路对容值精度与温漂要求较高,应优先考虑 NP0/C0G 等一类陶瓷;X7R 更适合容量/体积优先的场合。
  • 注意 DC bias 导致的有效容值下降:在高压工作点或需保证较大有效容值时,应查阅三星的 DC-bias 曲线或做样件测试。
  • 对长时间稳定性敏感的设计,应考虑老化效应并在设计裕量中体现。
  • 如需更高纹波电流或更低 ESR,考虑更大尺寸或专用电容类型(钽电容、电解电容等)做配合。

七、总结

CL10B105KB8NQNC(SAMSUNG,0603,1 μF,50 V,X7R)在体积与电压兼顾的前提下,提供较高的电容密度和良好的旁路去耦性能。适合移动设备、消费电子及一般电源滤波场景。实际应用时应关注 X7R 的温度依赖、DC-bias 及老化特性,合理布局与并联策略可获得最佳电源完整性效果。购买与工程验证前建议参照三星完整数据手册与 DC-bias、温漂曲线进行确认。

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
