20 Kohm 1/4w Film Resistor
The 20 Kohm 1/4W film resistor is a workhorse passive that belongs in every parts drawer, whether you are scaling a sensor voltage, biasing a transistor stage or trimming gain around an op-amp. Pair it with an LDR in a classic divider and an Arduino pin can tell dusk from daylight, letting you build automatic night lamps and light meters in minutes. At 0.25 watt with a ±5% band it shrugs off continuous duty on 5V and 3.3V rails, and the 20 Kohm film resistor price in Bangladesh keeps it practical to stock by the hundred for school labs. Axial through-hole leads push straight into breadboards, veroboards and PCB pads with no special tools. Buy 20 Kohm 1/4w Film Resistor in Bangladesh from Tekko and keep this versatile value ready for your next divider or bias network.
