Surface mount RF transformer with a 1:5 impedance ratio, designed for impedance matching and push-pull amplifier applications in the 0.3 to 300 MHz range. The part has a 50Ω impedance and operates within a temperature range of -20°C to 85°C, with a maximum RF power of 0.25W and DC current of 30mA. It is packaged in the KK81 case style, measuring 7.62 x 6.86 x 5.84 mm, and is RoHS compliant. Insertion loss is 0.7 dB typical at mid-band, with input return loss greater than 15 dB across most of the band. Pin connections are defined as primary dot (4), primary (6), secondary dot (3), secondary (1), and secondary center tap (2).
