CGA2B2NP02A471JT0Y0F 产品概述

一、产品简介

TDK 型号 CGA2B2NP02A471JT0Y0F 为贴片多层陶瓷电容(MLCC),规格为 470 pF ±5%(J),额定电压 100 V,温度系数 NP0(亦称 C0G)。该器件采用 0402 封装(约 1.0 × 0.5 mm),面向对温度稳定性、频率特性和低损耗有较高要求的应用场景。适用于精密滤波、振荡器、计时电路以及高频/射频回路中作为高稳定性旁路或耦合元件。

二、主要电气与物理参数

  • 容值:470 pF
  • 容差:±5%(J)
  • 额定电压:100 V DC
  • 温度系数:NP0 / C0G(温漂极小,近似零温度系数)
  • 封装:0402(约 1.0 × 0.5 mm)
  • 品牌:TDK

NP0(C0G)材料特性带来高 Q 值、低介质损耗和极小的温度依赖性,适合在 -55°C 到 +125°C(具体工作温度范围请参考器件数据手册)内保持稳定容值。

三、性能特点与优势

  • 温漂极小:NP0/C0G 类型在温度变化下的容值变化非常小,适用于对时间常数和频率稳定性要求高的电路。
  • 低损耗、高 Q:在高频下表现良好,适合射频前端、滤波和谐振回路。
  • 高耐压:100 V 额定电压为电源滤波、电压采样、脉冲抑制等场合提供更大安全余量。
  • 小型化封装:0402 封装利于高密度 PCB 布局,减小寄生电感、电阻,改善高频性能。
  • 品牌与一致性:TDK 品质控制和良好批次一致性,适合对可靠性有要求的工业与通信类设计。

四、典型应用场景

  • 高频滤波与阻抗匹配(射频前端、IF/VHF/UHF 电路)
  • 精密振荡器与定时电路(晶体振荡器周边、频率合成模块)
  • 仪器仪表和测量系统中的旁路与耦合
  • 高压偏置网络、采样与分压电路中需要较高耐压的小容量元件
  • 通信设备、测试测量、工业控制等对稳定性要求高的领域

五、封装与装配建议

  • 推荐遵循 TDK 数据手册中的推荐焊盘和回流焊工艺参数。0402 体积小,对焊膏量、焊盘尺寸和回流曲线敏感。
  • 控制回流峰值温度与时间(遵循 JEDEC/IPC 标准),避免超过器件允许的最高回流温度。
  • 防止 PCB 在波峰或回流后产生强烈挠曲或机械应力,贴片电容对机械弯曲较敏感,可能引发裂纹或可靠性问题。
  • 在高电压或关键电路设计中,建议考虑适当的电压裕度与电压降额设计,并留意直流偏压对容值可能产生的微小影响。

六、可靠性与认证

该系列 MLCC 通常经过严格的温度循环、湿热、机械冲击与高温储存等可靠性测试。若用于汽车或其他需要专门认证的领域,应确认该具体型号是否具有 AEC‑Q200 或相应行业认证,并参考 TDK 提供的可靠性报告与焊接规范。

七、采购与替代建议

  • 包装形式一般为胶带卷盘(Tape & Reel),适配自动贴片机;订购和批量采购请以 TDK 官方资料为准。
  • 常见可替代品牌:Murata、KEMET、Yageo、Samsung 等厂家的 C0G/NP0 0402 470 pF ±5% 100 V 系列型号,但在替换前请核对尺寸、温漂、额定电压及可靠性要求以保证电气和机械匹配。

备注:以上为基于器件标称参数的通用概述,具体电气性能、尺寸公差、回流参数及认证信息请以 TDK 官方数据手册与规格书为准,并在设计与生产前确认最新版本的技术文件。

Sourcing availability signal

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
