This RS brand LHK Series 105°C Axial Aluminium Capacitor features a safety vent construction design. Suitable for a variety of purposes, it is commonly used for communication equipment applications and for switching power supply.

Whenever there is a requirement for high capacitance values, Aluminium Electrolytic Capacitors will support your applications.

We are introducing our own branded RS PRO Aluminum Electrolytic Capacitor giving you up to 2000 hours of constant DC voltage (50 V dc) at a temperature of up to +105°C. Not to mention looking after filtering applications in switching power supplies and having a direct impact on extending the lifespan of the motherboard VRM's and other applications. The ability to support these devices without causing any harm to your application lies in low ESR (Equivalent series resistance) assuring you that the heat inside is under control.

If the additional increase of 10°C arises inside of the Capacitor, this can double the rate of chemical reactions; therefore, it is crucial to choose the right one for your project carefully.

The function of Ripple Current, in this case, 2.8 A is particularly important as a higher Ripper Current reduces the heat of your Capacitor and in turn, making it ultra-reliable and have a longer-lasting life.

Aluminum Electrolytic Capacitors have their place in:

• Motherboards


• Switched-mode power supplies


• DC-DC converters


• Frequency converters as DC link Capacitors for drivers or inverters for photovoltaic


• Audio AC signals

What is the average life of Aluminium Electrolytic Capacitors?
Today's Electrolytic Capacitors last around two years as long they are kept according to their specifications.

What is the reason for using Electrolytic Capacitors in the power supply?

It is mainly because of the large capacitance and pretty small size, which helps to reduce the Ripple Voltage.

How do you find the leakage current of a capacitor?

There are at least two methods available.
1. Apply an Ammeter with the Capacitor or
2. Use a Voltmeter in parallel with a resistor to connect to the Capacitor.
