MPP THINZ are ring cores made of Nickel 79%, Ferrum 17% and Molybdenum 4% powders which are characterized by an extremely small thickness from 1.5 to 2 mm. High temperature stability in combination with low losses, high saturation magnetic flux density and a permeability being highest among other powder materials make these cores a perspective choice for the using in a series of applications, particularly in production of small-size high-stability inductance coils for operation in wide temperature range.
In order to minimize an increase of height and to decrease an internal diameter, cores are covered with a "parylene" coating. Maximum operating temperature for parylene is 130 °C. Nevertheless, the coating remains stable over a short time period even at temperature 200 °C (for example, at infrared welding).
