Surface Mount Transformers
Made of a compact ferrite core, the HM33 Series transformers are uniquely designed to achieve maximum performance in a small package. Congruent with surface mount process temperatures, this construction is suitable for use with surface mount pick and place machinery.
The HM33 Series offers turns ratios ranging from 1:30 to 1:125 at 10 kHz, thus minimizing the wattage of the terminating resistor. Custom ratios are also available to accommodate the specific needs of circuit designers. Inductance values range from 180 to 3000 μH, with maximum dc resistance down to 1 Ω, depending on the design. Operating temperatures range from -25°C to +105°C
