PTC resistor
[ˌpiː tiː ˈsiː rɪˈzɪstər]
nounmasculinepl: PTC resistors
resistor PTC
1. A positive temperature coefficient resistor; a type of thermistor whose electrical resistance increases significantly with temperature, commonly used as a self-regulating heating element or overcurrent protection device
The PTC resistor automatically limits current when the circuit temperature rises above a certain threshold.
O resistor PTC limita automaticamente a corrente quando a temperatura do circuito sobe acima de um certo limite.
2. A ceramic or polymer-based electrical component that exhibits rapid increase in resistance as temperature increases, used in thermal protection and heating applications
PTC resistors are widely used in electric heaters and circuit protection applications.
Os resistores PTC são amplamente utilizados em aquecedores elétricos e aplicações de proteção de circuitos.
PTC resistors are technical components primarily used in electrical engineering and electronics manufacturing. The term is used identically in both Brazilian Portuguese and English-speaking countries, as it is a specialized component name in the electronics industry without significant regional variations. Knowledge of this term is essential for electrical engineers, technicians, and those working in heating and circuit protection industries.
