Motor Run Capacitors   Discharge Lamp Capacitors   Fan Capacitors   Ignition Capacitors   Zn-Al Metallized Polypropylene Film   Plastic Case Radial Lead   Tubular Axial Lead   Flat Oval Axial Lead NMC Series Capacitors are manufactured with Zinc Aluminum Alloy High Edge Metallized Polypropylene Film and housed in Polypropylene / Aluminum casing and sealed with high graded epoxy resin. These capacitors are of Self-Healing type with very low Dissipation Factor and have a long life. This series can be manufactured with a Safety device to ensure a Burst-Proof construction and to be of a Fire Retardant nature.   Applications These capacitors are used in a variety of AC Applications such as Motor Run, Phase correction, Inverters, Power Supplies, Air Conditioners, Air Coolers and in other appliances where medium duty motors are employed.   Specifications Capacitance Range 2.0 mF to 50.0 mF Capacitance Tolerance + /- 5% Rated Voltage 250 VAC / 320VAC / 400 VAC / 440 VAC Test Voltage   a) Between Terminals 1.75 x Rated Voltage b) Between Body and Terminals 2000 VAC at 50 Hz for 1 Minute minimum Dissipation Factor ( Tan delta) 0.35% at 50 Hz at 20 deg. C Temperature Range - 40 deg. C to + 85 deg. C Envionmental Category 40 / 85 / 21 Endurance Test 600 Hrs at 1.25 times rated voltage at 55 deg. C Self - Healing In the event of an overload, these capacitors self-heal, thus preventing them from short circuiting.
