Tolerance refers to the allowable variation in capacitance from the specified value. It is expressed as a percentage and is significant in applications where precise capacitance is required. Different manufacturers offer various tolerance ranges, which can affect the performance of the circuit in which the capacitor is used.
The temperature coefficient indicates how the capacitance value changes with temperature. Capacitors with a low temperature coefficient are preferred in applications where temperature variations are expected, as they maintain stable performance. Manufacturers may offer capacitors with different temperature coefficients, impacting their suitability for specific environments.
ESR is a measure of the resistive losses in a capacitor and is crucial for determining its efficiency in high-frequency applications. A lower ESR value indicates better performance, especially in power supply circuits. Different manufacturers provide capacitors with varying ESR values, which can influence the choice of capacitor for specific applications.
