CL31B224KCPWPNE 产品概述

一、概述

CL31B224KCPWPNE 是三星(SAMSUNG)生产的一款贴片多层陶瓷电容(MLCC),额定电容 220nF(0.22μF),公差 ±10%,额定电压 100V,介质类型 X7R,封装尺寸 1206(3.2mm × 1.6mm)。属于中高电压等级的通用型陶瓷电容,适用于需要体积与电容量平衡,同时要求较高工作电压的工业与电源类电路。

二、主要电气参数

  • 容值:220nF(0.22μF)
  • 精度:±10%
  • 额定电压:100V DC
  • 介质:X7R(温度范围常规为 -55°C 到 +125°C)
  • 封装:1206(公制约 3.2 × 1.6 mm)
  • 封装形态:表面贴装(SMD)

(注:实际工作时电容随温度、频率和直流偏置会发生变化,详细曲线请参照厂方数据手册。)

三、性能特点

  • 高电压承受能力:100V 额定可满足多数功率转换、传感器供电、放大器偏置等需要较高耐压的场合。
  • X7R 介质:在宽温区间内保持较大电容量,比 C0G(NP0)容量密度高,成本更低,适合耦合、去耦和旁路等用途。
  • 封装优势:1206 在体积与焊接强度之间取得平衡,便于手工和自动贴装。
  • 多层结构带来的低等效串联电阻(ESR)和较低等效串联电感(ESL),对中高频去耦效果良好。

四、典型应用场景

  • 开关电源输入/输出滤波、储能旁路
  • 功率转换器的降噪、回路稳定
  • 高压模拟电路的耦合/隔直
  • 工业、通信设备中的去耦与滤波
  • 需要在限小空间内实现较大电容值的模块化电路

五、设计与选型建议

  • DC 偏置注意:X7R 类电容在较高直流电压下会出现明显的有效电容下降,应参考厂方的电压-电容曲线并预留裕量。若电容值在偏置下不足,应选更大额定值或并联多只。
  • 温度与老化:X7R 在低温或长期使用中存在电容随时间和温度漂移的特性。对精密定时或高稳定性需求应考虑 C0G 类替代方案或混合配合使用。
  • 并联与分级:为兼顾大体积电容与高频滤波,可将本型号与小容值的 C0G/NP0 电容并联,以覆盖更宽的频率响应并降低 ESR。
  • 版图与焊接:1206 尺寸允许较强的焊盘承载,建议遵循厂方推荐的焊盘及回流焊工艺规范以降低应力导致的裂纹风险。

六、可靠性与使用注意

  • 机械应力敏感:陶瓷电容器对弯曲和机械应力敏感,PCB 设计与拆装时要避免过大弯曲或冷热冲击。
  • 清洁与贮存:避免长期潮湿环境,贴片前后遵循湿敏等级与回流温度曲线,必要时进行烘烤去湿处理。
  • 质量验证:关键应用建议进行加速寿命、温度循环与振动测试,确认在目标环境下的性能稳定性。

七、总结

CL31B224KCPWPNE(三星 1206,220nF,100V,X7R,±10%)是一款面向工业和电源类应用的通用高压 MLCC,兼顾体积、电容量与耐压性能。选用时应重视 DC 偏置、温度特性及机械应力,必要时结合厂方数据手册和电容随电压/温度的曲线图进行最终设计确认。若需更高稳定性或频率响应,可考虑与 C0G 型电容配合使用或选用更大容量并联方案。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
