12 Ohm 1/4W 5% Resistor Kit – 50 Pieces

Description

Technical Specifications

The 12 Ohm 1/4W 5% Resistor Kit is a set of 50 pieces of resistors with a value of 12 ohm, designed to limit the flow of current in electronic circuits. These resistors are useful for projects that require the protection of sensitive devices such as LEDs or sensors, ensuring that the current does not exceed the allowed limits.

The resistors are manufactured with a tolerance of 5%, meaning the actual value can vary up to ±5% from the nominal value of 12 ohm. The maximum power of these resistors is 1/4W, which requires attention during use to avoid overloading.

For proper use, it is necessary to verify the value of the resistor and its correct connection in the circuit. Use a multimeter to measure the value and ensure that the resistor is correctly inserted into the circuit.
