TDK P27 NTC Inrush Current Limiters
TDK P27 Series NTC Inrush Current Limiters (ICLs) are designed with a high material density for compact and efficient performance. These limiters feature a 27mm disk diameter, 7.5mm lead spacing, and offer a resistance range from 0.5Ω to 10Ω at 25°C, with the ability to handle currents up to 30A, depending on the type. The low resistance of P27 ICLs ensure minimal power dissipation in both AC and DC circuits. These ICLs are UL 94 V-0 rated, RoHS compliant, and are used in large electric motors, high-power supplies, and industrial equipment like plasma cutters.
