CGA2B1X7R1E333KT0Y0F 产品概述

一、产品简介

TDK 型号 CGA2B1X7R1E333KT0Y0F 为多层陶瓷贴片电容(MLCC),规格为 33 nF,容差 ±10%,额定电压 25 V,介质为 X7R,封装 0402(公制约 1005)。该系列面向高密度贴装的通用去耦与滤波场景,兼顾体积与频率响应性能。

二、主要参数与电气特性

  • 标称电容:33 nF(0.033 μF)
  • 容差:±10%(E-3)
  • 额定电压:25 V DC
  • 介质:X7R(工作温度范围 -55°C 至 +125°C,温度对电容影响在 ±15% 范围)
  • 封装:0402(适合高密度 PCB 布局)
  • 高频特性:MLCC 具有低 ESR/低 ESL,适合高频旁路与噪声抑制
    注意:X7R 为 II 类介质,存在温度依赖、直流偏置(DC bias)依赖与随时间的老化效应,实际工作电容可能随温度、偏压与时间发生可观变化,具体数值请参考 TDK 数据表曲线。

三、性能特点与使用注意

  • 高频旁路与 EMI 抑制性能优良,可直接贴近电源引脚布置以降低寄生阻抗。
  • 直流偏置特性:在接近或达到额定电压时,电容值会降低,可能降幅达数十个百分点(受介质与体积影响较大),如对绝对电容值敏感,应预留裕量或选用更高电压等级/稳定性更好的介质(如 C0G)。
  • 温漂与老化:X7R 在温度与时间上有一定变化,非精密定时或高稳定性场合优先考虑。
  • 机械可靠性:0402 体积小、易碎,焊接与机械应力管理需注意,避免在 PCB 边缘或受力点附近直接贴装。

四、封装与焊接建议

  • 推荐采用常规无铅回流焊工艺,遵循 TDK 的回流曲线规范以避免热应力导致裂纹。
  • PCB 焊盘设计建议对称,以防 tombstoning;留有适当焊膏量与锡面形状以保证焊接可靠性。
  • 对于存在热循环或机械振动的应用,考虑使用更大封装或增加应力缓冲结构。

五、典型应用场景

  • 微控制器与数字芯片的中高频去耦/旁路(与大容量电解、电容并联形成宽频响应)。
  • EMI/EMC 滤波、信号链的中频滤波元件。
  • 模拟电路的旁路与隔离(非精密耦合场合)。
    不建议用于要求长期高稳定性或严格温漂控制的定时、谐振电路。

六、选型与替代建议

  • 若电压依赖或温漂不可接受,可选用 C0G/NP0 系列;若需要更高工作电压或更小偏置效应,考虑同系列更高电压等级或更大封装。
  • 并联不同容量与封装的电容能扩展频率覆盖:如 33 nF 与 100 nF/1 μF 并联,兼顾中低频与高频去耦。

七、可靠性与合规

  • TDK 产品通常符合 RoHS 要求,具体认证信息与可靠性试验数据请以厂商发布的数据表与应用说明为准。
  • 设计时应考虑热循环、机械冲击与焊接工艺对小型 MLCC 的影响,必要时进行电气与机械可靠性验证。

总结:CGA2B1X7R1E333KT0Y0F 在体积极小的 0402 包装下,能提供 33 nF 的中等容值,适合高密度 PCB 的去耦与滤波应用。使用时需关注 X7R 的温漂、直流偏置与机械应力特性,合理布局与选型可发挥其优越的高频性能。

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
