TPSD226K035R0200 产品概述

一、产品简介

TPSD226K035R0200 是 AVX 的表面贴装钽固体电容器,额定容量 22 µF,容差 ±10%,额定电压 35 V,等效串联电阻(ESR)为 200 mΩ(@100 kHz),工作温度范围 -55 ℃ 到 +125 ℃,封装为 CASE‑D‑7343。此型号以高能量密度、体积小和稳定的直流特性为特点,适合在对体积、可靠性有较高要求的电子系统中做滤波与去耦使用。

二、主要特性

  • 容值:22 µF ±10%;适合中等容量需求的去耦/滤波应用。
  • 额定电压:35 V;支持中等工作电压的电源轨。
  • ESR:200 mΩ @100 kHz;在中高频下提供适度阻抗,有利于稳定输出电压和抑制中高频纹波。
  • 工作温度:-55 ℃ ~ +125 ℃;适应工业级温度环境。
  • 封装:SMD CASE‑D‑7343,便于自动贴装与高密度布板。

三、电气性能与使用含义

  • ESR 与纹波:给定 ESR=0.2 Ω 时,电容对纹波电流的压降可近似按 Vr = Ir_rms × ESR 估算。例如 0.5 A 的交流纹波将带来约 0.1 V 的 ESR 压降。
  • 频率依赖:钽固体电容在低频到中频范围表现优良,容量随频率和温度变化较小,但在极高频区域阻抗不如陶瓷电容。实际电源设计常将钽与陶瓷并联以兼顾低频储能与高频去耦。
  • 极性:为极性电容,必须注意正负极连接,反向电压会导致失效或短路。

四、封装与可靠性

  • CASE‑D‑7343 SMD 结构便于 PCB 高密度布置,通常在封装表面有极性标识。
  • 钽固体电容以体积能量密度高、长期容量保持性好著称,但对浪涌电流与瞬态过压敏感;妥善的电压降额与浪涌保护可显著提高可靠性。
  • 工作环境:耐热至 +125 ℃,适合多数工业与通信设备;在高湿或强振动环境需按厂方推荐的可靠性规范处理。

五、典型应用场景

  • 开关电源输出滤波与稳压器/稳压芯片(LDO、DC‑DC)后端的储能与去耦。
  • 输入滤波(与陶瓷并联),抑制整流或转换器产生的低/中频纹波。
  • 工业控制、通信设备、电源模块、汽车电子(需符合汽车级要求时确认具体版本)等对体积与长期稳定性有要求的场合。

六、使用建议与注意事项

  • 电压降额:建议根据应用关键性及浪涌特性对额定电压进行适当降额(常见做法为 50%–80% 范围,具体取值按系统可靠性要求确定)。
  • 限制冲击电流:在可能出现大浪涌电流的场合加串联限流电阻或软启动电路,以防电容因浪涌而失效。
  • 焊接与回流:遵循 AVX 的回流曲线与焊接工艺指南,防止热应力或机械应力导致封装损伤。清洗时避免使用会侵蚀钽电容的化学剂。
  • 并联使用:为兼顾低频储能与高频去耦,建议与低 ESR 的多层陶瓷电容并联;在并联相同钽电容时注意均流与板上布局。
  • 存储与保管:避免高温高湿长期存放,贴装前保持原包装状态以防受潮或污染。

总结:TPSD226K035R0200 是一款面向中高电压、需要稳定中等容量与工业温度范围的钽固体电容,凭借 22 µF 的容量与 200 mΩ 的 ESR,在电源滤波与稳压输出旁路中能提供可靠的性能。设计时注意电压降额与浪涌保护可显著提升系统安全性与元件寿命。若需更详细的电气特性曲线、回流曲线或认证信息,请参考 AVX 官方数据手册。

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
