Product Groups;
NTC Thermistor
An NTC Thermistor (Negative Temperature Coefficient) is a temperature-sensitive resistor and a component whose resistance decreases as the temperature increases. It is highly sensitive to temperature changes. It is widely used in applications such as temperature measurement, control or protection in electronic circuits. It is usually manufactured from semiconductor materials like metal oxides.
Temperature Measurement: It is used to measure temperature in electronic devices, air conditioning systems, refrigerators and medical devices.
Temperature Control: It controls heating/cooling systems when used as a temperature sensor.
Overcurrent Protection: It shows a high initial resistance to prevent sudden current fluctuations in the circuit, and its resistance decreases as the temperature increases over time.
Starting Current Limiter: It is used in power supplies, electric motors or transformers to limit large current pulses at the initial start-up moment of the circuit.
Ceramic PTC Thermistor
Ceramic PTC Thermistor (Positive Temperature Coefficient) is a thermistor whose resistance increases with temperature. PTC thermistors are made of ceramic material and are usually manufactured using materials such as barium titanate (BaTiO₃). PTC (positive temperature coefficient) translates into that “the higher the temperature, the higher the electrical resistance”. When it reaches a certain temperature (Curie temperature), it protects the circuit by limiting the current.
Overcurrent Protection: The PTC thermistor is used to limit the overcurrent in electronic circuits. When the temperature rises, its resistance increases and reduces the current.
Heating Elements: The PTC thermistor can function as a self-regulating heater operating at a constant temperature.
Başlangıç Akımı Sınırlayıcı: Elektrikli motorlar veya transformatörlerde, devre ilk çalıştırıldığında oluşabilecek yüksek başlangıç akımını sınırlamak için kullanılır.
Starting Current Limiter: It is used in electric motors or transformers to limit the high starting current that may occur when the circuit is first started.
Temperature Sensors: PTC thermistor can be used for temperature monitoring and protection. However, it has a more limited temperature measurement range compared to that of NTCs.
Time Delay Circuits: Since the resistance changes over time, it is used in circuits that require a time delay.
Polymer PTC Resettable Fuse
Polymer PTC Resettable Fuse is a component that protects the circuit by detecting a overcurrent in a circuit. This fuse shows low resistance under normal operating conditions. However, in case of overcurrent, its resistance increases rapidly and limits the current passing through the circuit. When the current returns to normal, it resets itself and the circuit continues to work again.
Overcurrent Protection: It is used to protect electronic circuits in cases such as overcurrent or short circuit.
Temperature Sensor
Temperature Sensors are the sensors used to measure the temperature of the environment or an object, and convert it into an electronic signal. It is widely used in different applications to collect, monitor or control temperature data. Temperature sensors can generate analog or digital output signals and are available in a wide variety of designs.
Temperature Monitoring: Air conditioning systems (HVAC), thermostats, home automation systems, temperature control in industrial furnaces, monitoring the heating of motors and machines, measuring patient body temperature, temperature monitoring for microprocessors and GPUs, as well as battery management
Varistor
A varistor (Voltage-Dependent Resistor – VDR) is an electronic component that shows variable resistance depending on the voltage. The main task of the varistor is to protect the other components in the circuit by absorbing overvoltage surges (voltage pulses). Therefore, it is usually used in surge protection circuits. When a certain threshold voltage is exceeded (varistor voltage), the resistance of the varistor decreases rapidly and directs the overvoltage to the ground. Thus, it protects sensitive components in the circuit against high voltage.
Surge Protection: It prevents damage to components by absorbing voltage fluctuations in electronic circuits.
Protection Against Sudden Voltage Pulses: It protects devices against voltage pulses caused by lightning strikes, fluctuations in power lines or electromagnetic interference.
Gas Discharge Tube
The Gas Discharge Tube (GDT) is an overvoltage surge protection device. The gas discharge tube is usually filled with a gas mixture trapped in a glass or ceramic tube. When the voltage in the circuit exceeds the rated (triggering) voltage of the GDT, the gas in the tube becomes ionized. This ionization causes the gas inside the tube to become conductive and protects the electrical circuits against overvoltage pulses by providing a high-voltage discharge between the two electrodes.
Surge Protection: It is used to protect the circuit against high energy pulses. They can be used in many systems such as electrical panels, telecommunication systems, industrial/military systems and power grids.
ESD Suppressor
The ESD Suppressor (Electrostatic Discharge Suppressor) is a component used to protect electronic circuits against electrostatic discharge (ESD) pulses. ESD is a sudden high-energy electrostatic discharge that can severely damage the devices or prevent the circuits from functioning properly. ESD suppressors protect the components in the circuit by absorbing such discharges rapidly. It rapidly responds to ESD pulses at the nanometer level.
Electrostatic discharge protection: Protects the circuits against ESD pulses in microprocessors, sensors, portable electronic devices, high-speed data lines, automotive electronics, medical devices, industrial devices.
TVS Diode
TVS Diode (Transient Voltage Suppressor Diode) is a semiconductor device designed to provide protection against sudden voltage pulses in electronic circuits. TVS diodes quickly absorb voltage fluctuations, protecting the sensitive electronic components against damage. They act as a passive component in the circuit under operating voltage and pass a low leakage-current. When the voltage exceeds the clamping voltage of the TVS diode, the TVS diode switches to transmission quickly. This limits the voltage by directing the excess energy in the circuit to the ground or the power line. As soon as the voltage drops, the TVS diode returns to its normal high-resistance state.
Surge Protection: It protects portable electronic devices, industrial machinery, telecommunications equipment, automotive electronics and power supplies against sudden energy loads such as electrostatics and lightning strikes.
Spark Gap Protector
Spark Gap Protector is a surge protection device used to protect electrical circuits against overvoltage. Basically, it is designed by leaving a gap between two electrodes; this gap directs the energy by creating an electrical spark (arc) at a certain voltage level. Spark gap devices are often used in high voltage applications or to limit the effects of surge pulses
Surge Protection: It protects antenna towers, telecommunications equipment, industrial machinery, electrical grids and high voltage lines against sudden energy loads such as lightning strikes.
