NTC Thermistor 5 Ohm Inrush Current Limiter, 7.5A Continuous, 5D-20 Replacement

NTC Thermistor for Inrush Current Limiting This NTC thermistor offers a resistance value of 5Ω and is designed to handle a maximum continuous current of 7.5A, making it a practical choice for inrush current limiting and current detection in electronic circuits. The component measures 21mm by 4mm with a total length of 50mm, and the pin spacing of 9mm suits standard through-hole mounting on circuit boards. Reliable Performance for Circuit Protection The thermistor works by presenting a higher resistance at room temperature and reducing as it warms, which helps to limit the initial surge of current when equipment is switched on. This behaviour supports smoother start-up for power supplies and other devices where sudden current spikes could cause stress to components. With a body size of 21mm by 4mm and a pen size of 1mm by 26mm, the component is compact enough for use in a range of electronic assemblies. Practical Design Details The component is available in black and silver tone finishes, and the 9mm pin spacing provides a stable fit when soldered into place. The 5Ω resistance value and 7.5A current rating make this thermistor suitable for applications where moderate current limiting is required, such as in power adaptors, chargers, and similar equipment. Each unit is supplied individually, ready for installation into your project.
