TDK CGA2B2C0G1H391JT0Y0F 产品概述

一、产品简介

TDK 型号 CGA2B2C0G1H391JT0Y0F 为一款表面贴装多层陶瓷电容(MLCC),主要参数为:标称电容 390 pF、容量精度 ±5%(J)、额定电压 50 V、温度特性 C0G(亦称 NPO),封装 0402(约 1.0 mm × 0.5 mm)。该器件以其温度稳定性和低损耗特性,适用于对频率稳定性和线性要求较高的模拟及射频电路。

二、主要性能特点

  • 温度特性 C0G(NPO):温度漂移极小,电容随温度变化基本可忽略,适合高精度定时、滤波和振荡电路。
  • 低损耗、高 Q 值:介质损耗小,适用于高频、射频路径和高精度模拟信号处理。
  • 体积小、封装 0402:占板面积小,利于高密度 PCB 布局和轻薄化产品。
  • 高可靠性、非极性:多层陶瓷结构,无极性限制,适合直流与交流耦合场合。
  • 标称测量条件:通常在 25°C、1 kHz 下测定电容值(具体测试条件以厂家数据为准)。

三、典型应用场景

  • 高频耦合/旁路、去耦(尤其在对温漂和频率响应敏感的模拟电路中)。
  • 振荡器与滤波器网络(时钟、RF 前端、PI/LC 网络)。
  • 精密 ADC/DAC 前端采样与采样保持电路。
  • 时序电路的定时元件、相位噪声要求高的电路。
  • 体积受限的移动设备、传感器电子、射频模块与通讯设备。

四、电气与机械要点

  • 温度系数:C0G 介质在常用工作温度范围内表现出极低的温度依赖性,适合要求稳定容量的设计。
  • 电压依赖性:C0G 的电容值对偏置电压的敏感性很低,适用于 DC 偏置存在的应用。
  • 物理尺寸:0402(公制约 1.0 mm × 0.5 mm),对 PCB 布局的空间占用小,但对焊接与机械应力更敏感。
  • 焊接兼容性:适合回流焊工艺。为保证可靠焊点及性能,应遵循 TDK 推荐的回流曲线与预处理流程。
  • 存储与湿敏性:若为湿敏器件,出厂后需按制造商推荐的干燥/回流前烘焙处理,避免湿气引起的焊接缺陷或电容“爆裂”。

五、PCB 布局与焊接建议

  • 采用制造商或行业推荐的 0402 管脚形状与焊盘尺寸,确保良好焊接润湿和足够焊点强度。
  • 留出适当的焊盘过渡区,避免在元件附近钻布孔或走大电流过孔,以降低机械应力集中。
  • 对板边或弯折区域应避免直接贴装,以减少由于板弯曲引起的应力导致开裂的风险。
  • 对于长期在高温或高电压工况下工作的设计,建议预留安全裕量并在样机阶段进行热循环与焊接可靠性验证。

六、可靠性与使用建议

  • 建议在设计时考虑余量:尽量避免长期在额定电压与最高工作温度同时满载状态下运行,以延长可靠性寿命。
  • 对于关键通路或需长期稳定性的应用,进行相关的环境应力测试(高温存储、湿热、热冲击及机械冲击/振动)以验证整体系统表现。
  • 更换或替代时,优先匹配容量、精度、额定电压、温度特性与封装尺寸,以保持电路性能一致性。

七、选型与替代参考

  • 选型原则:优先匹配 C0G/NPO 介质、相同容量与精度、相同或更高额定电压与相同封装(0402)。
  • 替代来源:若需替代,可以在同类厂商(如 Murata、KEMET、Yageo 等)中查找满足上述关键参数的 MLCC,替代时注意不同厂家的焊盘推荐值和可靠性验证。

八、包装与订购信息

  • 此类器件通常以卷带(Tape & Reel)方式供货,便于 SMT 自动贴装。具体包装单位(如每盘数量)与储运要求以 TDK 官方订购信息为准。
  • 型号命名中包含容量、精度、介质与封装等信息,采购时请核对完整型号以免混淆相近参数产品。

总结:TDK CGA2B2C0G1H391JT0Y0F 为一款面向高稳定性、低损耗应用的 0402 封装 C0G MLCC,适合要求温度和电压稳定性高的精密模拟、射频及时序等场景。在设计与使用中请遵循 TDK 提供的焊接与布局指南,并在关键应用中做可靠性验证,以确保长期稳定工作。

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
