The TC1-15X+ is a surface mount RF transformer for 50Ω impedance matching from 350 to 1500 MHz. Packaged in the AT1521 case, it measures 3.81 mm × 3.81 mm × 0.33 mm and weighs 0.15 grams. Insertion loss remains below 2.0 dB across the band, with typical values as low as 0.38 dB. Return loss exceeds 8.5 dB throughout and reaches 30.48 dB at 1500 MHz. It supports 0.25 W RF power and 30 mA DC current, operating from -40°C to 85°C. The plastic-based design includes aqueous washable leads and a defined pinout: primary at pins 4 and 6, secondary at pins 1 and 3.
