CGA2B3X7R1E104KT0Y0F 产品概述

一、基本参数与标识

  • 型号:CGA2B3X7R1E104KT0Y0F(TDK)
  • 类型:多层陶瓷贴片电容(MLCC)
  • 容值:100 nF (0.1 μF)
  • 初始容差:±10%
  • 额定电压:25 V DC
  • 温度特性:X7R(-55 ℃ 至 +125 ℃,温度范围内容值变化特性符合X7R规范)
  • 封装:0402(公制 1005),非极性
  • 适用包装:常见卷带(详细包装方式请参见制造商资料)

二、主要特性与优势

  • 高度集成:0402 小封装适合高密度 PCB 布局,节省空间,适用于便携式与紧凑型设备。
  • 容值与电压平衡:100 nF/25 V 的组合在电源去耦与旁路应用中常见,可直接用于多数中低电压电源轨。
  • 温度稳定性:X7R 材料在 -55 ℃ 至 +125 ℃ 范围内保持相对稳定的介电特性(但存在温度相关的容值漂移,见下文说明)。
  • 低 ESR/低 ESL:陶瓷电容具有很低的等效串联电阻与电感,适合高频旁路与瞬态抑制。
  • 可靠性与寿命:TDK 品牌产品经过批量验证,具有较好的焊接和环境可靠性(具体可靠性等级与认证以制造商数据为准)。

三、典型应用场景

  • 电源去耦与旁路:放置于 IC 电源引脚附近,抑制高频噪声与供电瞬态。
  • DC-DC 转换器输入/输出滤波:用作快速旁路与短路瞬态响应的补偿元件。
  • 模拟电路与信号过滤:用于非关键温漂要求的耦合/滤波场合。
  • 移动终端、消费电子、物联网模组、通信设备等对体积与高频性能有要求的产品。

四、关于 X7R 与电容特性的说明

  • 温度系数:X7R 定义下器件在 -55 ℃ 至 +125 ℃ 温度区间内的容值变化可达 ±15%(X7R 对应的是介质在该温度范围内的容值变化特性,而初始容差仍为 ±10%)。
  • 直流偏压效应:高介电常数陶瓷在施加直流电压时会出现容值下降,且随电压接近额定值下降幅度增加。因此在靠近 25 V 应用时,实际有效容值可能显著低于标称值,应在设计时预留裕量或选择更高额定电压。
  • 频率特性:容值随频率上升而减小,XXR 类电容在高频旁路中仍然表现优秀,但对高精度滤波/时基场合需评估频率依赖性。
  • 漏电流与介质损耗:陶瓷电容漏电小、介质损耗低,适合一般电源旁路用途,但非极化也不适合替代电解电容的高容值低频去耦。

五、封装与焊接建议

  • PCB 布局:尽量将电容贴近被去耦的 IC 电源引脚,走线短且面积小以降低寄生电感。
  • 焊盘设计:按制造商/IPC 推荐的 0402 焊盘设计,保证稳定的焊点与良好回流焊接性。
  • 回流焊工艺:遵循 TDK 的回流焊温度曲线,控制峰值温度与加热/冷却速率,避免急冷急热引发应力破裂。
  • 机械应力:0402 尺寸微小但对基板弯曲、挤压较敏感,贴片及线路板加工时避免施加过大机械力,可通过合理过孔与焊盘设计降低应力集中。
  • 清洗与助焊剂:推荐使用符合工业标准的助焊剂与清洗流程,避免化学残留对焊点或器件造成影响。

六、选型与使用注意事项

  • 在关键或精密电路中,如果对温度稳定性与电压依赖性要求高,应考虑使用 C0G/NP0 类介质或并联低介质常数电容以补偿。
  • 对于接近额定电压工作的设计,建议评估 DC 偏压下的剩余容值,必要时选用更高额定电压的 MLCC。
  • 多个并联不同容值的电容能兼顾低频与高频去耦性能(例如 100 nF 与 1 nF/10 nF 并联)。
  • 若用于汽车、航天或医疗等高可靠场景,请向供应商确认是否通过相应认证(如 AEC-Q200)并获取最小失效率与加速寿命测试数据。

七、采购与资料获取

  • 订购型号:CGA2B3X7R1E104KT0Y0F(请以 TDK 最新资料为准)
  • 包装形式:0402 卷带包装(卷带/带盘信息请参考产品规格书)
  • 建议获取并保存:TDK 官方规格书(datasheet)、回流焊曲线、可靠性测试报告与失效分析文档,以便在生产与量产阶段参考。

如需更详细的电气曲线(温度特性、频率响应、DC 偏压曲线)、机械尺寸图或具体回流焊建议,我可以帮你检索并解读 TDK 官方规格书中的关键图表与数值。

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
