CL32B106KAULNNE — 产品概述

一、产品简介

CL32B106KAULNNE 是 SAMSUNG(三星)生产的一款片式多层陶瓷电容(MLCC),标称容量 10 μF,公差 ±10%(K),额定电压 25 V,介质材料为 X7R,封装尺寸 1210(公制约 3.2 mm × 2.5 mm)。这类元件以体积小、耐温性能好、等效串联电阻(ESR)低著称,常用于电源去耦、储能与滤波等场合。

二、主要规格要点

  • 容值:10 μF
  • 精度:±10%(K)
  • 额定电压:25 V DC
  • 介质温度系数:X7R(-55°C 至 +125°C,温度范围内电容量变化通常在 ±15% 以内)
  • 封装:1210(约 3.2 × 2.5 mm)
  • 封装形式:SMD(贴片),常见为卷带(tape-and-reel)供料,便于回流焊贴装
  • 典型特性:低 ESR、高频特性良好、耐温性与长期稳定性适中

(注:具体电气参数如容差随温度的实际变化、交流阻抗、等效串联电感/电阻等,请以制造商最新数据表为准。)

三、关键性能与注意事项

  • X7R 介质特性:X7R 是常用的温度补偿型介质,适用于多数通用电源与滤波场景。与 NP0/C0G 不同,X7R 属于介质常数较高的类型,因而能在较小体积下实现较大容值,但温度与偏压下容量会发生可观变化。
  • 直流偏压(DC bias)效应:多层陶瓷电容在施加直流电压时会出现电容下降,尤其是高介电常数材料。对于 10 μF/25 V 的 X7R MLCC,在接近额定电压时,有可能出现显著的容量降低(视具体材料与层数而定)。在关键电路应留有裕量,或通过并联更高额定电压或更大容量的电容来补偿。
  • 机械应力敏感性:1210 尺寸相对较大,受焊接冷却、PCB 弯曲或机械应力可能导致裂纹或潜在失效。贴装布局需避免元件位于机械应力集中或弯折区。
  • 温度与老化:X7R 在高温或长期使用中容量会缓慢变化,须在热设计与寿命评估中考虑。

四、典型应用场景

  • 开关电源输入/输出侧的去耦与储能
  • DC–DC 转换器的输出滤波
  • 微处理器、电源管理芯片的电源去耦
  • 消费电子(智能手机、平板、笔记本等)和工业电子电源滤波
  • LED 驱动、通信设备和其他需要中等容量、紧凑封装的场合

五、PCB 设计与装配建议

  • 布局:将 MLCC 放置在电源引脚或敏感器件引脚附近,尽量缩短走线与电感环路,附近设置足够的贴地/去耦层。
  • 走线与过孔:对于大电流路径使用多条过孔降低寄生阻抗,避免过长走线引入额外电感。
  • 贴装工艺:遵循无铅回流焊温度规范(通常最高峰温度约 260°C,具体见器件焊接说明),使用推荐焊膏印刷量(一般建议焊膏覆盖率 60%–70% 以平衡焊点强度和翘曲风险)。
  • 焊盘与丝印:参考 IPC-7351 标准建议的封装与焊盘尺寸,确保焊膏量与焊点质量稳定。
  • 抗裂设计:避免将大封装 MLCC 放在 PCB 易弯曲区域;在需要时使用柔性粘接剂或增加应力缓冲区件。

六、可靠性与选型建议

  • 并联使用:为提高实际高频去耦效果与降低直流偏压影响,常将 10 μF X7R 与若干小容量(如 0.1 μF、1 μF)低感电容并联使用,覆盖更宽频带。
  • 电压裕度:在对电容值敏感的应用中,考虑采用更高额定电压或更大标称容值的元件以补偿 DC bias 带来的衰减。
  • 环境与寿命:若产品需满足更严格环境或功能安全要求,应查阅厂商可靠性数据(热循环、温度湿度、震动、寿命加速测试等),并根据应用场景选择合适等级的零件或备选方案。
  • 数据表核实:在最终设计与量产前,请参考 SAMSUNG 官方数据表获取完整电气、机械与可靠性参数(如等效串联电阻 ESR、等效串联电感 ESL、温度/偏压曲线、焊接条件与包装信息)。

总结:CL32B106KAULNNE 作为一款 1210 封装的 10 μF/25 V X7R MLCC,在体积与容量之间提供了良好折中,适合大多数中高频电源去耦与储能场合。设计时需注意 DC bias、温度特性与机械应力,并结合并联小容量电容与合理的 PCB 布局以获得最佳系统性能。

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.
