LOW PROFILE SPLIT BOBBIN MICROPROCESSOR
PRINTED CIRCUIT POWER TRANSFORMERS

 

Low profile - allows closer printed circuit board stacking. Split bobbin construction - center flange insulation barrier provides 2500 VRMs Hipot - non concentric coil winding results in low interwinding capacitance, eliminates need for electro-static shielding. Class S (130 C) insulation system.	Single 115V and Dual 115V/230V primaries are standard. DC output combinations -  +/-12 and 5V or +/-15 and 5V rated at the regulator output  with allowance for the line variations up to +/-13%. Packaging Flexibility.
