A three part concentrically wound bobbin is utilised to provide improved primary to secondary coupling together with improved frequency response and return loss characteristics. <1.5dB 200Hz - 4kHz with 600 Termination Insertion loss Return loss <-24dB 200Hz-4kHz with 600 Termination <0.03% THD 300Hz - 4kHz -10 dBM/600 Linearity Saturation <10V RMS 50Hz, 65V peak. PRI to SEC Reinforced (Tested 4kV RMS for 1 minute) Isolation dc resistance Primary Typically 50 10% , Secondary Typically 60 10% Leakage Inductance Typically 4 mH Approved to EN60950 and EN41003 BABT Certificate of Recognition CR/0126 Type Z1612E This 600:600 Line Isolation/Matching Transformer is a very low distortion version of the industry standard OEP1200 device for use in V.34 applications. In common with that product this transformer is designed for use where the telephone line current is diverted from the winding by a choke or solid state device. Its use will enable users to comply with the requirements of BS6305. Resin encapsulated in flame retardant cases. All materials are UL94-V0 rated. 0dB/600 , f=450Hz. 2nd Harmonic -88dBm. Distortion Insertion loss 1.5dB max 2kHz. Return loss -20dB 200Hz-4kHz. Isolation longitudinal 3.5kV RMS or 5kV peak. Saturation 10V RMS 65V peak 50Hz. file:///C /Documents%20and%20Settings/BennettR/Desktop/MISSING/OEP%20Home%20Page.htm (1 of 2)24/03/2006 09:46:19OEP Home Page Better than 80dB 200Hz-4kHz.
