VISHAY PTCCL Series PTC Thermistor, Through Hole

The VISHAY PTCCL Series PTC Thermistor is a precision electronic component designed for reliable overload and over-temperature protection in a wide range of circuits. Featuring a positive temperature coefficient (PTC), its resistance increases significantly at a defined switching temperature, effectively limiting current to protect sensitive components.

Constructed for through-hole mounting, this thermistor offers a stable resistance of 25Ω at 25°C, with a tolerance of ±20%. It is engineered to handle a maximum operating voltage of 60V, making it suitable for various low to medium voltage applications. A key operational characteristic is its defined current thresholds: it can hold a maximum current of 130mA and will trip at 195mA, providing predictable and safe circuit interruption.

Built to perform in demanding environments, it operates across a broad temperature range from -40°C to +85°C. Its precise switching occurs between 135°C and 145°C, ensuring protection is activated consistently when critical temperatures are reached. This makes it an ideal, self-resetting safety device for power supplies, motors, transformers, and battery packs.

With compact dimensions of 43mm x 33mm x 15mm and a weight of 30 grams, it is a robust yet space-efficient solution for PCB designs requiring dependable thermal management and circuit protection.
