HI,
Is there any limitation in choosing the resistor and capacitor for a frequency generating circuit using 555 timer in astable mode.

I am using R1 as 47ohms and R2 as 147ohm and C1 as 0.1(104) microfarad. I am intending to generate a 40KHz frequency. Is there any circuit to drive ultrasonic transmitter(40KHz).Any solutions to solve this problem please....
