series introduction
# Introduction to the EEU - FM1H471 Product Series
## Overview
The EEU - FM1H471 product series belongs to the realm of electronic components, specifically electrolytic capacitors. These capacitors play a crucial role in a wide range of electronic circuits, serving functions such as energy storage, filtering, and coupling. The EEU - FM1H471 series is engineered to meet the demanding requirements of modern electronic applications, offering high - performance and reliable operation.
## Technical Specifications
### Capacitance
The "471" in the model number indicates the capacitance value. In the standard capacitor notation, 471 means \(47\times10^{1}\) picofarads. However, for electrolytic capacitors in this series, the actual capacitance is \(470\) microfarads (\(\mu F\)). This relatively large capacitance value makes the EEU - FM1H471 suitable for applications that require significant energy storage, such as power supply filtering circuits.
### Voltage Rating
The "1H" in the model number is related to the voltage rating. In the capacitor industry's coding system, "1H" typically represents a voltage rating of 50 volts. This means that the EEU - FM1H471 capacitors are designed to operate safely at a maximum voltage of 50V. It is important to ensure that the voltage across the capacitor in the circuit does not exceed this rating to prevent damage to the component.
### Tolerance
The EEU - FM1H471 series usually has a capacitance tolerance of around ±20%. This means that the actual capacitance of a capacitor in this series can vary within 20% of the nominal value of 470\(\mu F\). For example, the actual capacitance could range from \(470\times(1 - 0.2)=376\mu F\) to \(470\times(1 + 0.2)=564\mu F\). This tolerance should be taken into account when designing circuits where precise capacitance values are critical.
### Temperature Range
These capacitors are designed to operate within a specific temperature range. Typically, the EEU - FM1H471 series can function effectively from - 40°C to +105°C. This wide temperature range makes them suitable for use in various environments, including industrial settings where temperature fluctuations can be significant.
### Equivalent Series Resistance (ESR)
The ESR of the EEU - FM1H471 series is relatively low. A low ESR is beneficial as it reduces power losses and heat generation within the capacitor. In power supply filtering applications, a low - ESR capacitor can more effectively smooth out voltage ripples, resulting in a more stable power output.
## Physical Characteristics
### Package Size
The EEU - FM1H471 capacitors come in a standard electrolytic capacitor package. The size is designed to be compatible with common printed circuit board (PCB) layouts. The compact size allows for easy integration into various electronic devices, whether it is a small consumer electronics product or a larger industrial control system.
### Terminal Configuration
The capacitors have two terminals, which are typically made of a conductive material such as copper. The terminals are designed for easy soldering onto the PCB. The polarity of the electrolytic capacitor is clearly marked on the body of the component, with the positive terminal usually indicated by a longer lead or a marking on the capacitor's case.
## Applications
### Power Supply Circuits
One of the primary applications of the EEU - FM1H471 series is in power supply circuits. In a switching power supply, these capacitors are used for input and output filtering. At the input side, they help to filter out high - frequency noise from the AC power source
