T490B337M006ATE800 产品概述
一、产品简介
T490B337M006ATE800 为 KEMET（基美）出品的固态钽电解电容，额定容量 330 μF，容差 ±20%，额定电压 6 V，封装型号 1411（3528 公制）。该器件属于钽电容系列，适用于要求体积小、容量密度高且稳定性的电子设备电源滤波与去耦场合。
二、主要参数
- 容值：330 μF ±20%
- 额定电压：6 V
- 等效串联电阻（ESR）：800 mΩ
- 工作温度范围：-55 ℃ ～ +125 ℃
- 封装：1411（3528 公制）表面贴装
- 品牌：KEMET（基美）
三、性能特点
- 高容量密度：在 3528 大小封装中实现较大的电容值，节省 PCB 面积与体积。
- 稳定的滤波与去耦性能：适用于低频纹波抑制和电源稳压回路。
- 中等 ESR：800 mΩ 的 ESR 在滤波与瞬态响应间取得平衡，可用于对 ESR 有特定要求的电源应用。
- 宽温度工作范围：-55 ℃ 至 +125 ℃，适应工业级温度环境。
- 极性器件：钽电容为有极性器件，安装时需注意极性标识。
四、典型应用
- 手机基板、便携式设备电源滤波与储能。
- 工业控制、电源模块的去耦与稳定化电路。
- 各类 DC-DC 转换器输入/输出滤波。
- 需在空间受限但要求高容量的嵌入式电子设备。
五、封装与安装建议
- 采用 1411（3528）贴片封装，适配常见贴片贴装工艺（回流焊）。
- 钽电容对焊接热敏感，建议按照厂商回流焊温度曲线与时间窗进行焊接，避免过热导致性能退化。
- 注意极性标识，严禁反向施加电压，反向或浪涌电压可能引起损坏甚至短路。
六、选型与注意事项
- 若电路中存在较大浪涌电流或频繁的脉冲，应评估是否需要更低 ESR 或更高额定电压的器件，或在前端加浪涌限制保护。
- 在高可靠性应用建议留有容量裕量并考虑工作电压的降额使用。
- 对比陶瓷及铝电解：与陶瓷相比钽电容容量稳定、体积小但极性限制明显；与铝电解相比寿命与稳定性通常更优。
七、可靠性与环境适应性
T490B337M006ATE800 具有宽温特性与长期稳定性，适合工业级应用场景。为确保长期可靠运行，建议遵循制造商关于储存、焊接和电气应力（浪涌、反向电压、过压）限制的规范，并在关键应用中进行必要的验证测试。

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.
