Large-diameter Inrush Current Limiters Serve High-watt Apps

04 February 2016

The P27 series of EPCOS NTC inrush current limiters from TDK Corp. have a nominal disk diameter of 27 mm and lead spacing of 7.5 mm, extending the portfolio of large NTC ICLs for industrial electronics applications. The high material density of the NTC ICLs enables a volume-efficient, high-performance design with a disk thickness of just ≤7 mm. The P27 series exhibit a rated resistance of 0.5 Ω to 10 Ω at 25 °C and can handle high currents of up to 30 A, depending on type.

Thanks to their very low resistance in the operating state, NTC ICLs offer very low power dissipation in both AC and DC circuits. The large-diameter components of the P27 series are suited 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.

The coating material of the P27 series of ICLs is flame retardant and UL 94 V-0 approved. The parts are RoHS-compatible and UL approved (E69802).

Samples of the P27 series are available.
