They are particularly well suited for application as line filters in switch-mode power supplies commonly used in desktop computers, industrial electronics, office equipment, and consumer electronics. The smallest of the Series, Model 7400, measures 19 X 21.0 mm, allowing high-density placement in space-restrictive board layout designs.
Depending on model, inductance values range from 0.6 to 45.0 mH. They operate over 55 to 105°C and are rated for 250 Vac and have a dielectric strength of 3,750 Vrms. Dc resistance is specified from 0.025 to 2.68 Ω The new inductors also feature high attenuation at low frequency and are constructed with flame-retardant-plastic bobbins.
