T598D226M035ATE065 产品概述

一款由 KEMET(基美)出品的高可靠性钽聚合物芯片电容,型号 T598D226M035ATE065,专为汽车与高可靠性电子系统设计。该元件在紧凑体积内提供较高电容值与极低等效串联电阻(ESR),兼具宽工作温度与 AEC‑Q200 汽车级认证,适用于要求抗振动、耐高温与高脉冲能力的电源去耦与能量缓冲场合。

一、主要参数

  • 容值:22 µF
  • 容差:±20%(M)
  • 额定电压:35 V DC
  • 等效串联电阻(ESR):65 mΩ @ 100 kHz(0.065 Ω)
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 封装:2917(7343 公制,尺寸 7.3 × 4.3 × 2.8 mm,D case)
  • 端子形式:Inward L(倒 L 型 SMD 端子,利于焊接和机械强度)
  • 类型:钽聚合物电容(Tant Polymer)
  • 认证:Automotive AEC‑Q200
  • 包装:T/R(卷带带盘)

二、关键特性与优势

  • 高容值密度:22 µF 在 7.3 × 4.3 × 2.8 mm 的封装内实现,节省电路板空间,便于在空间受限的电源前后级部署。
  • 低 ESR:0.065 Ω(100 kHz)能显著降低纹波电压和功率损耗,提高稳压器输出稳定性与热性能,利于处理高频纹波与开关噪声。
  • 宽温工作域与汽车级可靠性:-55 ℃ 到 +125 ℃ 的工作温度范围配合 AEC‑Q200 认证,适用于车载电子(如 ECU、车载通讯、ADAS)、工业控制和其他严苛环境。
  • 钽聚合物介质:相比传统氧化铝电解电容,钽聚合物在 ESR、稳定性与寿命方面具有更优表现,且在高频去耦与瞬态响应上效果突出。
  • 可回流贴片与牢固的机械连接:Inward L 端子设计兼顾焊接良率与抗振动性能,减小焊点应力集中,适合自动化贴装与回流工艺。

三、典型应用

  • 汽车电子:电源去耦、MCU/SoC 旁路、传感器前端滤波、车载信息娱乐与通信模块的后级滤波。
  • 电源模块:DC‑DC 转换器的输入/输出去耦、稳压器后端缓冲、能量暂存以应对瞬态负载。
  • 工业与电信:高可靠性控制器、基站设备电源滤波、精密测量仪器的稳定电源设计。
  • 消费电子(需考虑额定与可靠性):高端便携设备的电源滤波与瞬态支撑。

四、机械与封装信息

  • 公制封装标识为 7343,亦可对应 2917 系列尺寸规范;典型外形尺寸为 7.3 mm × 4.3 mm × 2.8 mm(长×宽×高)。
  • Inward L 端子(倒 L 型)便于在 PCB 上形成可靠焊点,适配自动化贴装与回流焊工艺。
  • 提供卷盘(T/R)包装,利于批量贴装生产线的连续供料。

五、设计与选型建议

  • 电压与浪涌:在应用中应参照 KEMET 官方资料进行电压裕量设计,避免频繁超过额定电压或遭受高幅度浪涌;对关键节点建议适当降额(根据系统可靠性要求确定)。
  • 热管理:尽管 ESR 较低,但在高纹波电流环境下仍会产生热量。布板时注意热散与附近热源,保证器件工作温度不超限。
  • 耐久与寿命:钽聚合物电容具有良好循环稳定性,但长期可靠性与寿命受温度、电压与纹波电流影响,建议在关键应用中结合实际工况做加速寿命评估。
  • 焊接工艺:遵循 KEMET 推荐的回流焊曲线与 PCB 焊盘设计,Inward L 端子对焊接有一定容错,但仍需控制回流峰值温度与时间以保证焊点质量。

六、认证与质量保证

  • 产品符合汽车级 AEC‑Q200 认证要求,适配严格的汽车电气环境与可靠性测试;适用于车规级设计与量产导入。
  • 建议在最终设计验证阶段参考 KEMET 的具体数据手册(datasheet)及可靠性报告,以获取详细的电气特性曲线、试验标准与使用注意事项。

如需获取该型号的完整数据手册、阻抗频率曲线、纹波电流额定值或样品与供货信息,可联系供应商或访问 KEMET 官方资料以获得权威数据与支持。

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
