The NCS4-521+ is a ceramic balun RF transformer with a 1:4 impedance ratio, designed for bandwidths from 223 to 520 MHz at 50 ohms. It features LTCC construction in a miniature 0805 package measuring 0.079" × 0.049" × 0.033". The device exhibits a maximum insertion loss of 1.5 dB, amplitude unbalance of 1.5 dB, and phase unbalance of 10 degrees across its operating range. It supports up to 2 W RF power and operates reliably from -40°C to 85°C. The part is RoHS compliant and uses a GE0805C-9 case style with a specified PCB land pattern.
