CK1V471M-CRG10贴片铝电解电容产品概述

CK1V471M-CRG10是容强(ROQANG)针对中低压滤波、储能场景推出的工业级贴片铝电解电容,采用小型化SMD封装设计,兼顾高纹波承载能力与宽温适应性,适用于工业控制、电源模块、车载电子等多类紧凑化场景。以下从核心特征、性能参数、封装规格等维度展开详细概述。

一、产品定位与核心特征

该电容定位为小型化宽温贴片铝电解电容,核心特征包括:

  1. 贴片封装适配自动化贴装,降低生产难度与成本;
  2. 470uF容值+286mA纹波电流能力,满足多数电源滤波、储能需求;
  3. 宽温工作范围(-40℃~105℃)与2000hrs高温寿命,适配严苛环境;
  4. 紧凑尺寸(D10xL10.5mm),支持PCB高密度布局。

二、关键性能参数详解

1. 容值与精度

容值标称470uF,精度±20%,符合铝电解电容常规精度标准,可满足多数滤波场景的容值需求(如开关电源输出滤波、线性电源稳压)。

2. 额定电压

直流额定电压35V,实际应用需遵循电压降额原则(建议工作电压不超过额定值的80%,即28V以内),避免纹波叠加导致过压损坏。

3. 纹波电流能力

在120Hz频率下允许纹波电流286mA,该参数直接影响电源滤波效果——若纹波电流超过限值,电容会因损耗发热加速老化,甚至失效。需注意:纹波电流随频率升高会有所提升(厂家通常提供频率-纹波电流曲线),实际应用需结合工作频率调整。

4. 寿命与温区

  • 高温加速寿命:2000hrs@105℃(即105℃环境下连续工作2000小时,容值变化、损耗角等仍符合行业标准);
  • 工作温区:-40℃~105℃,覆盖工业级环境(如户外设备、高温车间、车载低温启动场景)。

三、封装与尺寸规格

采用SMD贴片封装,电容体规格为直径10mm×长度10.5mm,属于小型化封装范畴:

  • 引脚设计符合IPC标准,支持回流焊、波峰焊工艺(需遵循厂家焊接温度曲线,峰值温度≤260℃);
  • 紧凑尺寸适配高密度PCB设计(如小型电源模块、便携式医疗设备),可替代部分插件电容实现小型化升级。

四、可靠性与环境适应性

1. 高温稳定性

105℃高温下2000hrs寿命,说明电容电解液、铝箔等核心材料的热稳定性优异,避免长期高温下漏液、鼓包、容值衰减过快等问题。

2. 宽温适应性

  • 低温端(-40℃):容值衰减率符合行业标准(通常≤20%),可正常工作于寒冷地区或低温启动场景;
  • 高温端(105℃):无明显性能下降,满足工业设备持续高温运行需求。

3. 抗振动性能

贴片封装通过表面贴装与PCB紧密结合,抗振动性能优于传统插件电容,可适配车载电子、工业机器人等振动场景(振动频率通常支持10~2000Hz,加速度≤1.5g)。

五、典型应用场景

该电容因性能与封装优势,广泛应用于以下场景:

  1. 开关电源滤波:AC-DC电源、DC-DC转换器的输出滤波,抑制纹波(如12V/24V电源模块);
  2. LED驱动电源:小功率LED灯具(如台灯、面板灯)的储能与滤波,适配宽温环境;
  3. 工业控制模块:PLC、传感器节点、伺服驱动器的电源部分,满足工业级可靠性要求;
  4. 车载电子:车载充电器、仪表盘、倒车影像的电源滤波,适配-40℃~85℃车载温区;
  5. 便携式设备:移动电源、小型医疗监护仪的辅助储能,兼顾小型化与性能。

六、选型与应用注意事项

  1. 极性确认:铝电解电容为极性电容,焊接前需严格确认正负极(通常电容表面有负极标识),反接会导致电容击穿损坏;
  2. 纹波电流控制:实际工作纹波电流需≤286mA@120Hz,若工作频率>120Hz,可参考厂家提供的频率-纹波电流曲线(通常频率越高,允许纹波电流越大);
  3. 焊接工艺:回流焊需遵循“预热→升温→峰值→冷却”曲线,避免局部过热导致电容损坏;
  4. 存储条件:未焊接电容需存储于常温(25℃±5℃)、干燥(相对湿度≤60%)环境,避免长期暴露于高湿环境(铝电解电容易吸潮);
  5. 电压降额:实际工作电压(含纹波峰值)需≤额定电压的80%,延长电容寿命。

该电容通过RoHS认证,符合环保要求,是工业与消费类电子领域小型化电源设计的可靠选择。
