KNSCHA科尼盛217EC0031 SMD铝电解电容产品概述

一、产品定位与核心优势

217EC0031是KNSCHA科尼盛针对低压高频紧凑电路设计的表面贴装(SMD)铝电解电容,核心聚焦「高纹波承载、低ESR、宽温可靠」三大特性,适配消费电子、工业控制等多领域的电源滤波、耦合需求。其470μF容值搭配10V额定电压,兼顾储能能力与低压系统兼容性,是替代传统插件电容、优化PCB布局的高性价比选择。

二、关键电气参数详解

1. 容值与精度

标称容值470μF,精度±20%,满足大多数电源滤波场景的储能需求——例如5V/3.3V系统的后端滤波,可有效抑制电压波动,避免电路误触发。

2. 纹波电流与ESR

支持2.6A@100kHz的纹波电流承载,搭配32mΩ@100kHz的低等效串联电阻(ESR):在开关电源等高频环境中,低ESR可显著减少电容自身发热,提升系统效率,同时降低电磁干扰(EMI)。

3. 额定电压与寿命

10V额定电压适配低压电路(避免过压风险),**2000hrs@105℃**的工作寿命可覆盖长期高温场景(如工业烤箱、车载发动机舱周边)——假设每日工作8小时,实际寿命超1000天,满足设备长周期运行需求。

4. 温度范围

工作温度覆盖**-55℃至+105℃**,可应对极端低温(如北方户外设备)与高温场景,环境适应性远超普通民用级电容。

三、机械封装与尺寸规格

217EC0031采用SMD封装,具体尺寸为:

  • 电容体直径:6.3mm
  • 电容体长度:7.7mm
  • 引脚间距:2.5mm

紧凑的尺寸设计使其能嵌入高密度PCB(如智能手机充电器、小型路由器),有效节省电路板空间;引脚采用标准化设计,兼容自动贴片机生产,焊接可靠性高,减少虚焊风险。

四、可靠性与环境适应性验证

科尼盛对该产品完成多轮可靠性测试:

  • 高温寿命测试:105℃环境下持续运行2000小时,容值变化率≤±10%,ESR变化率≤±20%,符合工业级标准;
  • 温度循环测试:-55℃至+105℃循环100次,无漏液、开路等故障;
  • 焊接可靠性测试:经回流焊工艺后,引脚无脱落、电容体无变形,满足SMT量产要求。

五、典型应用场景

  1. 消费电子:手机快速充电器、LED台灯/球泡灯电源、便携式蓝牙音箱的电源滤波模块(紧凑尺寸适配小体积产品);
  2. 工业控制:小型PLC电源模块、传感器节点电源(宽温适应工业现场高低温波动);
  3. 汽车电子:车载USB充电器、行车记录仪电源(-55℃低温适配北方冬季,105℃高温适配发动机舱周边);
  4. 通信设备:小型无线路由器、IoT网关的电源滤波(低ESR减少信号干扰)。

六、总结

217EC0031凭借均衡的电气性能、紧凑尺寸与宽温可靠性,成为低压高频电路中铝电解电容的优选方案,可有效提升系统效率与稳定性,适配多领域量产需求。

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
