Hi there, I'm trying to build a soft-starter circuit with 2N2222 transistor. But I'm struggling to get a fix on the R1, R2 and C1 values. Now the relay engages as soon as the power up (I see no delay). I'm trying to come up with 300~500milliseconds delay from power-up to relay engaging. [image…

For 5 V, an IRLZ44. Transistor (BJT) circuit will not work.

Drive 5v relay with 2N2222
