CA45-A010K476T — 钽电容产品概述

一、产品概览

CA45-A010K476T 是一款高可靠性钽电解电容,额定容量 47 µF,额定电压 10 V,容差 ±10%。该产品由湘怡中元/湘江品牌生产,封装为 CASE-A_3216,适用于对容值密度和温度稳定性有较高要求的小型电子设备。典型工作温度范围为 -55 ℃ 至 +125 ℃,适合工业级与部分苛刻环境使用。

二、主要电气参数

  • 容值:47 µF
  • 容差:±10%
  • 额定电压:10 V
  • ESR(等效串联电阻):2 Ω @ 100 kHz
  • 工作温度:-55 ℃ ~ +125 ℃
  • 封装:CASE-A_3216(封装尺寸参考 3.2 mm × 1.6 mm)
  • 产品型号:CA45-A010K476T

三、性能与特点

  • 高容值体积比:钽材料本身具有较高的比电容,47 µF 在 CASE-A_3216 小封装中能提供较大的储能。
  • 温度稳定性好:在宽温区间内保持容量与阻抗的稳定,适合高温工作环境。
  • 较低的自放电和漏电:相对于铝电解电容,钽电容漏电与自放电更低,利于电池供电设备的待机与保持电容应用。
  • 频率特性:在高频(如 100 kHz)下 ESR 为 2 Ω,适合去耦与高频滤波场合,但仍需注意高频纹波和脉冲电流的限制。
  • 极性元件:为极性电容,必须正确连接正负极,禁止反向电压。

四、典型应用场景

  • 稳压电源滤波与去耦:用于 MCU、电源管理 IC 周边的旁路与稳压输出滤波。
  • 便携式与消费电子:在空间受限但需较大电容值的便携设备中,可提供良好电源稳定性。
  • 工业控制设备:在温度与电气环境较为严苛的场合,可作为辅助滤波或缓冲元件。
  • 音频电路与低频滤波:凭借较稳定的容量用于音频耦合与滤波,需考虑极性与失效保护。

五、使用与焊接注意事项

  • 电压与降额:为提高可靠性,建议在实际应用中对额定电压进行降额(例如工作电压不超过额定值的 50%~80%,具体根据可靠性要求调整),尤其在高温或重复浪涌环境下。
  • 脉冲与浪涌电流:钽电容对瞬态大电流较敏感,长时间或反复的浪涌可能导致失效或短路。对高浪涌场合应加串联限流电阻或采用保护电路。
  • 极性识别:装配时必须确认正负极方向,反接会造成损坏甚至起火。
  • 焊接工艺:建议按照厂商推荐的回流曲线进行焊接,避免过高峰值温度和过长加热时间;手工焊接时避免长时间加热引脚。
  • 储存与搬运:避免潮湿与强机械冲击,贴片卷盘在 SMT 线使用前按规定回温回湿处理(如厂方有吸湿性说明,按其建议执行)。

六、封装与订购信息

  • 品牌:湘怡中元 / 湘江
  • 型号:CA45-A010K476T
  • 封装形式:CASE-A_3216(SMT 贴片)
  • 包装:常见为卷带包装(tape & reel),适配自动贴片生产线
  • 选型建议:在确认系统工作电压峰值、脉冲特性及温度条件后选用;如需更低 ESR 或更高耐脉冲能力,可考虑并联多只或选择专用低 ESR 系列。

如需更详细的电气特性曲线(Q-C、ESR vs. frequency/temperature、漏电流 vs. 温度/电压)或可靠性认证与封装尺寸图,请提供您的联系方式或具体要求,我可以为您进一步查找或向厂方索取数据手册。

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.

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
