CL10B333JB8NNNC 产品概述

一、产品简介

CL10B333JB8NNNC 是三星(SAMSUNG)系列贴片多层陶瓷电容器(MLCC),规格为 0603(公制 1608)。标称电容为 33nF(0.033µF),初始容差 ±5%(J),额定直流电压 50V,介质类别为 X7R。该型号适用于对尺寸、可靠性和中等温度稳定性有综合要求的电子产品中做旁路、去耦、滤波和耦合等用途。

二、主要电气与材料特性

  • 容值:33nF(0.033µF),精度 ±5%(J)。
  • 额定电压:50V DC。
  • 介质:X7R(温度范围 -55°C 至 +125°C,温度引起的电容变化在 ±15% 以内,属于类 II 高介电常数材料)。
  • 封装:0603(1608 公制),适合高密度 PCB 布局。
  • 无极性,低等效串联电阻(ESR)与低感抗(ESL),适合高速去耦和滤波应用。

三、典型应用场景

  • 电源旁路与去耦:放置在芯片电源引脚附近,抑制高频噪声与瞬态干扰。
  • 模拟滤波:结合电阻或电感构成低通/高通滤波器。
  • 耦合/去耦电路:信号链中进行交流耦合或旁路低频干扰。
  • 时序/定时电路(非高精度场合):用于 RC 时间常数,但需要注意 X7R 的温度和偏压漂移。
  • 移动设备、通信设备、消费类电子、工业控制等需小体积滤波的场合。

四、设计与选型注意事项

  • DC Bias(直流偏压)效应:X7R 为高介电常数陶瓷,施加直流电压时电容值会下降。设计时应考虑工作电压下的实际有效电容,必要时参考厂家典型 DC-bias 曲线或留有裕量。
  • 温度稳定性:X7R 在 -55°C 至 +125°C 范围内电容变化可达 ±15%,不适用于要求高稳定性的谐振或高精度定时电路。
  • 尺寸与封装:0603 封装在焊接、工艺与机械应力下相对更易损伤,应注意 PCB 设计与装配工艺控制。
  • 串联/并联:批量并联可增加总容值或降低等效电感;串联可提高耐压但会降低总容值并改变频率特性。

五、布局与焊接建议

  • 贴近负载/IC 电源引脚放置:尽量缩短走线、减小回流环路面积以提高去耦效率。
  • 使用完整的地平面:提供低阻抗回流路径,降低 EMI。
  • 焊膏与回流曲线:遵循制造商推荐的回流温度曲线,避免过高温度循环造成裂纹。
  • 机械应力控制:避免在贴片线路附近做大面积弯折或机械夹紧,焊盘设计要遵循厂方推荐封装焊盘尺寸,减少热膨胀差异引发裂纹。
  • 湿度敏感处理:按通用 SMD 器件做潮湿敏感等级(MSL)管理,必要时返工前烘干。

六、可靠性与合规

  • 一般适用于商业与工业级应用。关于具体的可靠性测试、耐焊性、寿命和合规证书(如 RoHS、REACH、汽车级 AEC-Q 等),建议参考三星官方数据手册或直接向供应商确认,以满足特定认证需求。
  • 在高应力或关键应用(如汽车安全、医疗等)中,如需高可靠性保证,请选用明确通过相关认证的型号或进行额外验证。

七、选购与替代考虑

  • 若电容在高偏压下需要保持较高的有效电容,可考虑降低工作电压或选择体积更大、介质衰减较小的型号。
  • 对温度稳定性和寿命有严格要求的场合,建议采用 C0G/NP0 型陶瓷或薄膜电容作为替代。
  • 采购时确认包装(卷带/盘装)、最小起订量、库存与交货期,并核对完整料号以避免误购。

总结:CL10B333JB8NNNC(33nF ±5% 50V X7R 0603)是一个在体积、性能与成本之间取得平衡的通用型 MLCC,适合常见去耦、滤波与耦合场合。设计时应重点关注直流偏压效应和布局焊接工艺,以确保电路在实际工作条件下的稳定性与可靠性。若需更详细的电气特性曲线与环境合规信息,请参考三星官方数据手册或联系授权分销渠道。

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.
