TDK CGA2B3X7R1H223KT0Y0F 产品概述

一、产品简介

TDK 型号 CGA2B3X7R1H223KT0Y0F 是一款贴片多层陶瓷电容(MLCC),容量 22 nF(0.022 μF),公差 ±10%,额定电压 50 V,介质为 X7R,0402 封装。该器件在体积极小的同时提供良好的频率响应和较低的等效串联阻抗(ESR),适合空间受限的现代电子产品做去耦、滤波及旁路使用。

二、主要电气参数

  • 容量:22 nF(0.022 μF)
  • 公差:±10%
  • 额定电压:50 V DC
  • 介质:X7R(温度范围 -55°C 到 +125°C,典型温度稳定性在 ±15% 范围)
  • 封装:0402(约 1.0 mm × 0.5 mm,适合高密度贴装)
  • 特性:低 ESR、低 ESL,适用于高频旁路与滤波

三、物理与封装说明

0402 超小型封装使该电容能够在 PCB 面积非常受限的位置使用,便于现代移动终端、便携设备及高密度模块化电路布局。器件采用表面贴装结构,支持无铅回流焊工艺与常见的贴片生产流程,通常以卷带(tape-and-reel)方式供货,方便 SMT 自动贴装。

四、典型应用场景

  • 电源去耦和旁路:在中低电压供电总线上抑制高频噪声,改善电源瞬态响应。
  • 高频滤波:与电感或其他电容组合用于 EMI 抑制、输入/输出滤波。
  • 耦合/旁路:在模拟信号链路中作为耦合或旁路元件,兼顾体积与性能。
  • 移动终端与可穿戴设备:适合对体积、重量和性能有严格要求的消费类电子产品。

五、选型与使用建议

  • 考虑直流偏置效应:X7R 陶瓷电容在施加直流偏压时会出现容量下降,在接近额定电压时降幅更明显。建议在关键去耦场合对容量进行适当降额设计或并联多只以保证所需有效容量。
  • 温度与频率响应:X7R 在宽温范围内性能稳定,但仍属于二类介质,若电路对容量精度和线性要求高(例如高精度计时或振荡电路),应优先考虑 C0G/NP0 型号。
  • 布局要点:为发挥去耦效果,应将电容尽量靠近电源引脚放置,走短回流路径,避免过多过孔引入寄生感抗。对需分频覆盖的噪声频段,可采用不同封装/容量的多级并联策略。
  • 焊接与寿命:遵循厂商推荐的回流曲线进行焊接。陶瓷电容存在随时间的老化现象(容量随使用时间缓慢下降),在长期稳定性要求高的设计中应予以考虑。

六、可靠性与品质保证

TDK 作为知名元器件厂商,产品通过 RoHS 等环保合规要求,并按照行业常规做温度循环、湿热、机械振动和焊接可靠性测试。对于批量采购或关键应用,可向供应商索取相关检验报告与品质保证文件,或选择经过更高等级认证(如汽车级 AEC)的相应系列产品以满足更严苛的可靠性需求。

总结:CGA2B3X7R1H223KT0Y0F 在极小封装下兼顾容量与耐压,适合一般电源去耦、滤波与高密度应用。设计时关注直流偏置与温度影响、合理布局与并联策略,可在体积受限的系统中实现良好的电气性能。

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
