Evelta SKU: 083-JQC3F-C-S-DC5V Manufacturer Part Number: JQC3F-C-S-DC5V. In theory as relays are coils and like to hold current there shouldn't be a current spike when I . Comments Required. Next C1 discharges through R2 and will be about 63% discharged after 0.1 seconds because 100uF x 1000 ohms give a 0.1 second tau or RC time constant. The way the circuit works is that when 5V is applied, C1 is momentarily a short circuit and current flows freely through C1 and R3 into the base of Q1. From this we can also figure out the relay coil impedance at different voltages using R = V/I. That being said, usually the thing that will reduce a relay’s power consumption the most is to simply use a latching relay. (A latching relay is designed to maintain its state once power is removed from its coil. While relays are very useful for switching things on and off, for situations where power consumption is to be kept to a minimum, the power used by the relay itself can be a problem – for example where a small LED light is to be switched, the power taken by the relay could be more than the power taken by the light. This mode keeps the relay activated while significantly reducing the power consumption. $8.99 $ 8. R1 = 526 - 128 = 398 ohmsWe need to use the nearest standard value of 390 ohms.
