Part Number: 9579250802 79 EQ Core-EQ25/8/18 Planar EQ and EQI cores, with their low profile, are suitable for board level installation allowing assembly without the need for plastic coilformers and can also allow windings integrated into multi-level PCBs. Planar EQ cores with their low mass and low profile are suitable for Surface Mount installations in low power filter and transformer applications. – Planar EQ and EQI cores can be supplied with the center post gapped to a mechanical dimension, or an A value. 11.0 (g) Σl/A : Core Constant, l : Effective Path Length, A : Effective Cross-Sectional Area, V : Effective Core Volume A : Inductance Factor Explanation of Part Numbers: Digits 1 & 2 = product class and 3 & 4 = material grade. A value is measured at 1 kHz, B < 10 gauss. A new high frequency material for power applications up to 750 kHz. This MnZn power ferrite is available in customer specific core designs. This material is available as special order for customer specific applications. **** Characteristic curves are measured on standard Toroids (18/10/6 mm) at 25°C and 10 kHz unless otherwise indicated. Impedance characteristics are measured on standard shield beads (3.5/1.3/6.0 mm) unless otherwise indicated.
