Types of Filter Chokes * Type 1: Smoothing Chokes -- Inductance Tolerance - Minus 15% Plus 50% at 10 Volts 60 Hz -- The Stancor line of "Smoothing" types of Filter Chokes has been designed for use with the various Power and Plate Transformers listed in this catalog. The range of electrical ratings available covers requirements for practically all of the Filter Chokes used in D.C. power supplies. In addition, a myriad of other electronic apparatus applications for these items exist. Inductance values shown are measured at the full amount of D.C. listed and at the specified values of RMS Voltage and Frequency. All of these items are made with Class "A" insulating materials and will withstand operation up to a limit of 105C., continuously. * Type 2: High Current Chokes -- Inductance measured at 1 Volt 60 Hz -- Inductance Tolerance - Minus 15%, Plus 50% -- The "High Current Chokes" listed are normally used in low voltage, high current D.C. power supply filter applications, where low voltage drop across the filter and good voltage regulation is required, without any type of voltage regulator. www.stancor.com 11
