SOWTER Type 3575

General Purpose Bridging Transformer

PACKAGE OPTIONS Part Number Canford Code
Colored Leads 3575-F 23-155
PCB Mounting 3575-C 23-156
APPLICATION For reduction of most kinds of noise caused when equipments are connected. For use where it is important not to load the driving circuit. Ideal as an input transformer for a valve amplifier to provide a balanced, isolated line input which will then accept balanced or unbalanced sources. Unbalanced to balanced conversion and vice versa. For helping to ensure Electromagnetic Compatibility (EMC) compliance.
FEATURES High impedance presents minimal load to source even at 15 Hz. Mumetal core for minimal harmonic distortion. Internal electrostatic shield for high common mode noise rejection. Mumetal can for magnetic shielding. Secondary centre tap for phase splitting etc.
RATIO 1:1ct
MAXIMUM LEVEL 0.5 % THD at 50 Hz (40 ohm source) +26 dBu
DISTORTION at 50 Hz (Source 40 ohms) 0.05% at +20 dBu
INSERTION LOSS 10k ohm source 10k ohm load 1.08 dBu
FREQUENCY RESPONSE 6k4 ohm source 10k ohm load +/- 0.25 dB 15 Hz to 60 kHz
