10 Air Conditioning/Motor Run
Capacitance up to 100 mF Single & Dual ratings available Voltage up to 660Vac Temperature up to 70°C Frequency 50-60Hz UL Recognized internal protection

11 Motor Start Capacitors
Pressure safety vent 2 blade quick connect terminals Moisture and Oil Resistant Case Requiring No Insulation Bleeder Resistors, Caps, and Brackets Available Type PSU

12 Type PSU Motor Start Voltages: 125, 165, 250, 330 Vac
Capacitance: to 1200 mF Temperature °C to +65 °C Frequency: to 60 Hz Aluminum Electrolytic Non Polarized

13 Type PSU For intermittent AC use in starting of split-phase motors
Cap specified as a range Example: mF Type I for garage door openers good for 75,000 starts. Type II for general purpose motor start - good for 50,000 starts

14 Type PSU Motor Start Markets Applications Home Appliances
Industrial equipment Motor Manufacturers Applications Electric motor starting Starting for split phase motors Garage door openers

15 DC/AC Rated Type OTB Dual rated for DC/AC Type OTB Metal case
Solder lug terminals with insulator cup Metal case Protected with an Internal pressure interrupter Paper, film & foil Impregnated construction Type OTB

16 Type OTB Dual Rated DC/AC

17 Type OTB DC/AC Dual Rated
Market Areas High voltage power supplies Power amplifiers EMI/RFI Filters Motors Applications Input / Output filtering Blocking & bypass Filtering Power factor correction

18 Solder lug terminals with insulator cup
Commutation / Snubber Type SCR and SNU Ceramic insulated screw terminals Solder lug terminals with insulator cup Metal case with Non ferrous covers optional Aluminum Case Type SCR Type SNU

19 Commutating Capacitors
Commutating in layman terms Is a reduction in severity of a punishment by law. Commutating in electrical terms A reversal of current direction or the conversion of alternating current to unidirectional current The cap takes the heat off the SCR

20 Type SCR and SNU Comparison
* This rating only, all the rest are 60 A

21 Type SCR and SNU Threaded studs on the SCR give the higher current rating The SNU aluminum case is ideal for welding applications where current flowing thru the capacitor creates a magnetic field that heats ferrous materials

22 Type SCR and SNU Markets Applications Power Conversion Welders
Power Supplies

23 DC Rated Capacitors Type T Ceramic insulated screw terminals
Hermetically sealed metal case Type T

24 Type T Filter Capacitors
High Voltage 600 Vdc to 15.0 mF 1000 Vdc to 15.0 mF 1500 Vdc to 15.0 mF 2000 Vdc to 15.0 mF 2500 Vdc to mF 3000 Vdc to mF 5000 Vdc to 2.0 mF

25 Type T Markets Applications Power Conversion
