TDK CGA2B3X8R1H103KT0Y0M 产品概述

一、主要参数

TDK CGA2B3X8R1H103KT0Y0M 为0402(1005英制)贴片多层陶瓷电容(MLCC),标称容量 10nF(103),容差 ±10%(K),额定电压 50V,介质材料为 X8R。X8R 意味着电容在宽温度范围内(典型 -55°C 至 +150°C)容量变化在可接受范围内(类二介质,温度稳定性优于普通Y5V类但不及C0G/NP0)。

二、产品特点

  • 小尺寸(0402)适合高密度印制板设计,节省空间。
  • X8R 介质兼顾容量与温度稳定性,适合工作温度较宽的场景。
  • 50V 额定电压在中低压电源滤波和隔离电路中具有良好适应性。
  • MLCC 本征 ESR/ESL 较低,响应速度快,适合去耦、滤波与旁路用途。
  • TDK 制造工艺成熟,可靠性高,适合消费类与一般工业电子产品。

三、典型应用场景

  • 数字芯片电源去耦(CPU、MCU、FPGA 的旁路电容)。
  • 模拟电路滤波与耦合(放大器输入/旁路)。
  • DC-DC 转换器输出滤波与补偿网络。
  • 高频信号链旁路与去耦(注意体积与自谐频率影响)。
  • 一般消费类、通信与工业电子设备。

四、设计与布局建议

  • 靠近电源引脚安放,走线尽量短且粗,减少回流环路面积以降低寄生感抗。
  • 考虑直流偏压效应:陶瓷电容在直流电场下会产生容量下降,设计时按实际工作电压下的有效容量选型或留裕量。
  • 0402 尺寸器件虽然小但对焊盘设计和回流曲线敏感,采用厂家推荐的焊盘尺寸和标准回流工艺,避免热应力和翘板效应。
  • 对于对温漂要求严格的应用,优先考虑 C0G/NP0;若要求体积更小且温度范围宽,X8R 为权衡选择。

五、可靠性与环境特性

  • X8R 介质在高温环境下仍能保持较稳定的电容值,适用于-55°C 至 +150°C 的工作温度范围(具体请参照厂家数据表)。
  • MLCC 对机械应力(如PCB 弯曲、过孔附近的应力集中)敏感,自动贴装与回流后建议进行机械可靠性验证。
  • TDK 通常提供符合 RoHS 的无卤版本,批次可靠性与寿命测试合格,适合量产使用。

六、替代与选型建议

  • 若需更高温漂稳定性(较小容量变化),可考虑 C0G/NP0 系列;若需更高电压或更大容量,可选择更大封装(如 0603/0805)或不同电压等级。
  • 市场上同类产品可考虑 Murata、KEMET、Yageo、Samsung 等厂商同规格 X8R MLCC,选型时关注在工作电压下的实际容值保留率与封装机械强度。

七、料号解读与采购提示

料号中的“103”对应 10nF,“K”表示 ±10% 容差,其他字符通常标识封装、额定电压、材料与包装形式。采购时请确认:温度系数(X8R)、额定电压(50V)、容差、封装(0402)与包装卷盘/切带规格;若对直流偏压或温度性能有严格要求,建议索取并审核厂家电容-电压特性(CV)曲线与温度系数数据表。

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
