We can use a standard 1000 uF capacitor and increase the resistor proportionally to get 15 seconds. The capacitor value for a 15 second delay will be 15/3R = 1327 uF. The resistor value will be the voltage/current = 10.6/0.003 = 3533 or about 3.6K. The voltage across the resistor will be the supply voltage minus two diode drops or 12-1.4 = 10.6.

For example a 120 ohm relay coil will draw 100 mA at 12 volts and assumming a transistor gain of 30, the base current will be 100/30 = 3 mA. The capacitor/resistor values can be worked out from the relay coil current and transistor gain. The time delay for the common emitter will be approximately 3 time constants or 3*R*C. Hari ini im akan memberitahu bagaimana membangun kualitas tinggi sederhana dan biaya amplifier yang efektif. IC TDA2616 keluaran Philips memang dibuat untuk penggunaan hi-fi dengan beban speaker 8.

The common emitter (circuit on the right) is the better circuit since the series base resistor can be selected to obtain the desired delay time whereas the capacitor must be selected for the common collector (or an additional resistor used in parallel with the capacitor).

The common emitter configuration on the right offers the advantage of the full supply voltage across the load for most of the delay time, which makes the relay pull-in and drop-out voltages less of a concern but requires an extra resistor in series with transistor base. However the voltage across the relay coil will be two diode drops less than the supply voltage, or about 11 volts for a 12.5 volt input. The circuit on the left is a common collector or emitter follower and has the advantage of one less part since a resistor is not needed in series with the transistor base.
