 Capacitors of this kind are mainly composed of type CT1 and CT81.
■ Feature
● Variation of capacitance with temperature is nonlinear within classification temperature range; having many kinds of temperature characteristics groups.
● Char.Bn:low dielectric loss, excellent frequency characteristics. Char.R:low dielectric loss; high temperature-resisting;excellent high frequency characteristics.Being suitable for capacitor fly back.
● Coated with flame-retardant epoxy resin which conforms to UL94V-0 standards.
● Taping available for automatic insertion.
■ Application
● Used as filter and coupling capacitor,among which R & Bn capacitors are specially suitable for high frequency pulse circuit, such as line-output circuit of colour TV set,high voltage rectifying circuit, switching power supplies and so on.
● High voltage circuit of other electronic equipment,such as energy-saving lamp,monitor and so on.
