Understanding Capacitor Types and Characteristics | DigiKey
Mica capacitors (mostly silver mica) are characterized by tight capacitance tolerance (±1%), low temperature coefficient of capacitance (typically 50 ppm/°C), exceptionally low dissipation factor, and a low capacitance variation with applied voltage. The tight tolerance and high stability make them suited to RF circuits.
