I am working on 500mhz signals. At these frequencies the 0.05pF of capacitance in a SMD resistor adds up. Today I am fighting inductance of resistors. Most data sheets say nothing about inductance and some just say “low inductance”. One sheet said “0.5 to 5nH” depending on resistance value.
Is there information on inductance verses resistor size? The real question; is it better to use one 1W resistor, four 1/4W resistors in parallel or 30 small 0603 in parallel. (paralleling reduces inductance)
