Capacitor
Capacitor (Product Code: SCL-451/122) is an electronic component that stores electric charge, used in charging and discharging, filtering and timing experiments in physics and electronics labs. It is listed with a 250 V voltage rating, well above the supplies used in typical low-voltage student circuits, together with a 105 °C temperature rating and a tolerance of 20%. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a regular part of any electricity experiment kit for school labs.

What Is the Capacitor Used For?
Capacitors store charge and release it again, which puts them at the centre of RC time-constant experiments: students charge a capacitor through a resistor and record how its voltage rises, then discharge it and watch the voltage fall. The same component smooths the output of rectifier circuits, blocks DC while passing AC signals, and sets the timing interval in timer IC circuits.
Observe polarity if the capacitor has marked positive and negative leads, and never exceed the 250 V rating. A capacitor can hold charge after the supply is removed, so discharge it through a resistor before handling it. The 20% tolerance means the measured capacitance may differ from the marked value, which is worth discussing when students compare calculated and measured time constants.
What to Specify When Ordering
- Capacitance value(s) required, as these are not stated on this page.
- Working voltage of your circuit, to confirm the 250 V rating suits it.
- Quantity per experiment set or bench.
- Whether a Capacitor Study Kit or charging and discharging apparatus is also needed.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Capacitor from Ambala, Haryana, to schools, colleges, laboratories and dealers in India and international markets. Physics departments setting up RC and rectifier experiments can combine capacitors with resistors, meters and power supplies in one enquiry. The ScienceLab company profile explains more about the company.

Frequently Asked Questions
What is the voltage rating of the Capacitor?
The Capacitor (SCL-451/122) is listed with a voltage rating of 250 V. Keep the working voltage below this figure; in most school and college RC experiments the supply is far lower, leaving a wide margin.
What are the temperature rating and tolerance of the Capacitor?
The Capacitor has a temperature rating of 105 °C and a tolerance of 20%, which means its actual capacitance may differ from the marked value by up to that percentage, so measure it when accuracy matters.
What capacitance values are available?
Capacitance values for the Capacitor are not listed on this page. Send the value your experiment requires through the contact page, and ScienceLab will confirm what can be supplied before sending a quotation.
Is the Capacitor safe to handle after an experiment?
The Capacitor can keep a charge after the supply is disconnected, so discharge it through a resistor before touching the leads. This is good practice for every capacitor used in school and college labs.
Who supplies the Capacitor?
The Capacitor is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, along with the capacitor study kits, resistors and meters that make up a complete RC experiment bench.
What should I include in a Capacitor quotation request?
A quotation request for the Capacitor should include the code SCL-451/122, the capacitance value, quantity and delivery location. Mention any resistors, meters or charging and discharging apparatus you want quoted with it.
