T520B476M010ATE035 产品概述
一、产品简介
T520B476M010ATE035 为 KEMET（基美）牌钽电容器，EIA 520（Case B）封装，标称容量 47 μF，额定电压 10 V，容差 ±20%。该型号面向需要高体积效率与稳定去耦、滤波的贴片应用，尺寸标注为 CASE-B-3528-21（约 3.5 × 2.8 × 2.1 mm），适合自动化贴片与高密度电路板设计。
二、关键电气性能
- 容量：47 μF，公差 ±20%
- 额定电压：10 V DC
- 等效串联电阻（ESR）：35 mΩ（@ 100 kHz）——低 ESR 有利于高频去耦与降低纹波。
- 工作温度范围：-55 ℃ ～ +105 ℃，适应较宽温度环境。
三、主要特点与优势
- 高容量/体积比：在 520 尺寸下提供 47 μF，可显著节省 PCB 面积。
- 低 ESR：35 mΩ 的典型值改善高频性能与热损耗，利于开关电源输出滤波与瞬态响应。
- 宽温度适应：可在工业级温度范围稳定工作。
- 贴片形式：适配回流焊与自动化装配，提高生产效率。
四、可靠性与设计注意
- 极性元件：钽电容为极性器件，焊接与电路布局时必须确保正确极性连接。
- 浪涌与冲击电流：钽电容对浪涌电流较敏感，建议在设计中考虑限流或增加串联电阻、软启动措施以降低击穿风险。
- 电压降额：为提高长期可靠性，建议依照厂方推荐进行电压降额使用；在高可靠性场合常采用更严格的降额策略。
- 温升与散热：在高纹波或高温环境下应评估功耗引起的温升，避免超出额定温度。
五、封装、焊接与包装
- 尺寸：CASE-B（约 3.5 × 2.8 × 2.1 mm），适用于 3528 类焊盘布局。
- 焊接：兼容无铅回流工艺，建议遵循 KEMET 的回流曲线与焊接指南，避免过高峰值温度与过长保温时间。
- 包装：通常提供卷带（Tape & Reel）包装，便于 SMT 生产线贴装。
六、典型应用与选型建议
- 开关电源输出滤波与稳压器去耦；
- 数字电路与 MCU 的电源旁路与瞬态抑制；
- 通信设备、便携式电源模块与工业电子的高密度电源滤波。
选型时综合考虑：工作温度、纹波电流、冲击电流能力与电压降额策略，必要时参考厂方等效型号或联系供应商获取更详细的性能数据与可靠性试验报告。
七、使用与储存注意事项
- 储存应干燥、防潮并避免强光直射与机械冲击；
- 装配前如有必要进行回流前预烘以去除吸湿；
- 安装时避免机械应力作用于电容体，焊盘设计与回流曲线需符合厂方规范。
总结：T520B476M010ATE035 在有限尺寸内提供较高电容量与低 ESR，适合多种电源滤波与去耦场景。为确保长期可靠性，应配合合理的电压降额、浪涌保护与正确的回流焊工艺共同设计。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
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.
