I am engineering student and I am based in UK and would like use some of your help on my course.

The topic I am currently studying on capacitor and hope you all will help me out

anyway I require the information for the air-spaced variable capicator such as:

• construction
• dielectric material
• capacitance range
• typical tolerance
• typical voltage rating [v]
• temperature coefficient [ppm/°C]
• stability
• ambient temperature range [°C]
• typical applications

also I hope I have posted right section.

Thank you by the way
