When you choose a resistor, these tolerances can significantly impact the performance across the resistor in your circuit. Precision applications require lower tolerance levels.
Power Ratings
Powe rating indicates the maximum power a resistor can dissipate without damage. This is generally measured in watts (W). For high-power applications, you need resistors with higher power ratings.
The temperature coefficient
The temperature coefficient measures how important the resistance value changes with temperature. Resistors with low-temperature coefficients are ideal for surroundings with shifting temperatures.
Choosing the Right Resistor
Opting for the right resistor for your project involves considering several factors, including resistance value, power rating, and tolerance. When you choose a resistor, remember to match its value to your specific requirements. This section will give practical tips for making the best choice.
Resistance value
The resistance value determines how important current overflows through the circuit. Choosing the correct resistance value ensures that your circuit operates as intended.
Calculating resistance
Ohm’s Law (V = IR) to calculate the required resistance value based on the circuit’s voltage and current specifications.
Value Resistor
Resistors come in standard values, so choose the closest available value to your calculated demand in ohms. Consider using multiple resistors in series or parallel to achieve the asked resistance. This approach can help you achieve a precise value of a resistor that may not be available as a single unit.
