Mini-Circuits 1:1 CORE & WIRE Transformer, 1.5 - 500 MHz, 50Ω TCM1-1X+

TCM1-1X+ is a surface mount RF transformer designed for impedance matching and balanced-to-unbalanced conversion in the 1.5 to 500 MHz range with a 50Ω system impedance. It features a DB1627 package measuring 4.06 x 3.81 x 4.06 mm with a height of 1.65 mm and weighs 0.15 grams. The transformer exhibits a typical insertion loss of 0.9 dB referenced to mid-band, with a maximum insertion loss of 2 dB across 2.5 to 400 MHz. It supports an RF power of 0.25 W and a DC current of 30 mA, with an operating temperature range of -20°C to 85°C and storage temperature of -55°C to 100°C. Pin configuration includes primary and secondary windings on pins 4/6 and 1/3 respectively, with pins 2 and 5 unused. The device is aqueous washable and has an amplitude unbalance of 0.2 dB typ. and phase unbalance of 4 deg. typ. within its 1 dB bandwidth.
