Inrush current limiters feature very low power dissipation

New NTC inrush current limiters (ICLs) from EPCOS for a wide range of industrial electronics applications can now be sourced through TTI Europe. Thanks to their very low resistance in the operating state, NTC ICLs offer very low power dissipation in both AC and DC circuits. The latest P27 series of ICLs features a nominal disk diameter of 27mm and lead spacing of 7.5mm, thus extending the portfolio of large ICLs for industrial electronics applications from EPCOS. The high material density of the ICLs enables a volume-efficient, high-performance design with a disk thickness of just =7mm. P27 series devices offer extremely stable and reliable electrical characteristics, a rated resistance of 0.5ohm up to 10ohm at 25C, and can handle high currents of up to 30A, depending on type. The coating material is flame retardant and UL 94 V-0 approved. The components are fully RoHS compliant and UL approved (E69802). The large-diameter components of the new series are especially suitable for use in large electric motors and drives and all kinds of high-watt power supplies as well as in industrial applications such as welding and plasma cutting equipment.
