Low_voltage_lamp_flasher_that_uses_a_PUT

Published:2009/7/22 3:59:00 Author:Jessie | From:SeekIC

This circuit shows a PUT used as a lamp flasher, where the supply is only 3 V. Q1, R1, and C1 form a relaxation oscillator. Q2 and Q3 form an SCR flip-flop. Notice that C4 is not a polarized capacitor. For the values shown, the lamp is on and off for about 0.5 s each.
