Capacitors - LOW ESR
Modern microprocessor technology requires power supply from auxiliary voltage sources. Such a solution, present in a growing number of microprocessor systems, guarantees high current efficiency, voltage stability and resistance to interference. It is also an additional protection against disturbances resulting from switching processes in power systems.
The necessity to meet the above tasks requires the use of a cost-effective power technology. It should be based on the use of capacitors with small geometric dimensions, but with a very large electrical capacity.
The solution to the above problem are Low ESR capacitors - electrolytic capacitors that have the appropriate maximum voltage and very large capacity. An important parameter is also the value of the series equivalent resistance, abbreviated as ESR - hence ESR capacitors. See all capacitors below now.
Electrolytic capacitor Low ESR 100uF/50V 8x11mm 105C THT - 10pcs
Low-impedance electrolytic capacitor (LOW ESR) 100 uF / 50 V. Output Raster: 3.5 mm. Size Ø8 x 11 mm. Price for 10 pieces.Electrolytic capacitor Low ESR 22uF/50V 5x11mm 105C THT - 10pcs
The ectrolytic through hole capacitor of low impedance (LOW ESR) 22 uF / 50 V. Pins' pitch: 2 mm. Size Ø5 x 11 mm. Price is for 10 pieces.Electrolytic capacitor Low ESR 10uF/50V 5x11mm 105C THT - 10pcs
The ectrolytic through hole capacitor of low impedance (LOW ESR) 10 uF / 50 V. Pins' pitch: 2 mm. Size Ø5 x 11 mm. Price is for 10 pieces.Electrolytic capacitor Low ESR 470uF/25V 8x12mm 105C THT - 10pcs
Low-impedance electrolytic chronic-impedance capacitor (LOW ESR) 470 uF/ 25V. Outputs shelf: 3.5 mm. Size Ø8 x 12 mm. Price for 10 pieces.Electrolytic capacitor Low ESR 47uF/35V 6,3x11mm 105C THT - 10pcs
Low-impedance electrolytic chronic-impedance capacitor (LOW ESR) 47 uF/ 35 V. Outputs Raster: 2 mm. Size Ø6,3 x 11 mm. Price for 10 pieces.Low ESR electrolytic capacitors
A completely resistance-free capacitor would be perfect for many applications. Unfortunately, this type of construction would be impossible as there is no material that can guarantee zero resistance. Nevertheless, Low ESR electrolytic capacitors are close to ideal in this respect.
The ESR skin itself stands for Equivalent Series Resistance and refers to the basic feature of the presented capacitors - reduced resistance. On the other hand, Low suggests that we are dealing with a low-impedance device. Low ESR electrolytic capacitors are low impedance capacitors with a very low resistance value. This variant of products can also be used for audio bands due to their use in low frequencies.
Why is the ESR parameter so important when choosing capacitors?
ESR is a parameter whose value depends both on the frequency of the signals at which the capacitor operates and the temperature. Age is another factor that influences the value of ESR - the value grows over time.
Low ESR electrolytic capacitors are widely used in various types of computers and other power supplies, intended for charging phones and those enabling the operation of other devices.
The capacitors used in the input stages of the power supplies act as a voltage buffer. They also ensure stability when the voltage on the side of the power grid is lower than the rated value. What's more, they maintain the desired voltage level also during switching operations, in a degree that converts alternating voltage into direct voltage. Capacitors prevent the transmission of switching disturbances. As for the power supply output, then the electrolytic capacitors ESR are responsible for the voltage waveform. In many switching power supplies, the switching processes are repeated with a frequency of several thousand Hertz. It should be remembered that the higher the switching frequency when using ordinary electrolytic capacitors with a high ESR value, the lower their efficiency on both sides of the power supply. It should also be remembered that the ESR is inversely proportional to the capacitance of the capacitor. The greater the capacity of the device, the lower the ESR level.
Modern capacitors for electronic projects in Botland
We invite you to purchase affordable, original and durable Low ESR electrolytic capacitors. At Botland's stores you will find low ESR electrolytic capacitors with the most popular capacitance values. Thanks to the low resistance value obtained thanks to the appropriate production technology, you will be able to successfully use these devices in your DIY electronic projects. You will use them for robotics and IoT projects. You can use them for various power supplies, electro-acoustic amplifiers. Use such capacitors for all devices that require high-quality signal filtering and care for their proper functioning, in accordance with the assumed design!
