该器件为钽电容,具有高体积比电容值、稳定的温度特性与较低的ESR。250 mΩ@100 kHz 的阻抗特性使其在中高频去耦和稳压器输出滤波中表现良好,能有效抑制开关噪声并改善瞬态响应。宽温度范围适合工业、汽车电子等苛刻环境。
CASE-B-3528-21 提供较小占位面积与适中厚度,适合表面贴装自动化生产。钽电容为极性器件,需按标识正确安装;封装尺寸和引脚形状对焊接工艺和热阻有影响,设计PCB焊盘时应参考厂家推荐。
钽电容对浪涌电流和反向电压敏感,建议设计时采用适当电压降额(常见50–80%视应用而定),并在可能的情况下增加串联限流电阻或浪涌抑制措施。遵循AVX 的回流焊曲线与储存/潮湿处理规范以避免焊接损伤。高温长期工况下关注容量与ESR随温度漂移,必要时参考厂家阻抗/容值曲线及寿命试验数据。
当要求更低ESR或更高频率特性时,可考虑多层陶瓷电容(MLCC)并联使用;若关注容量密度和稳定性,钽仍是优选。设计时同时评估纹波电流能力、在最大工作温度下的寿命以及电容缩容风险,必要时向AVX索取具体可靠性报告与应用指南。
TPSB476K010R0250 提供了在受限空间内实现较大电容值与良好中高频性能的解决方案,适合用于需要稳定去耦与滤波的工业和车载电源设计。最终设计应结合电压降额、浪涌保护及焊接工艺,参照AVX 官方技术资料以获得完整的性能与可靠性评估。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
