Steward´s ferrite toroids provide high performance when wound and used as cores for transformers, inductors, or chokes. A variety of materials and core sizes allow performance to be optimized for application size and frequency. Steward offers materials which provide the high inductance and low losses desired for high frequency transformers, materials which provide high impedance for low frequency EMI suppression, and materials which provide high impedance for high frequency EMI suppression. Small-sized, custom part shapes are also available in Steward 35 and 40 materials for specialized filtering applications.
Applications: ⊕ LAN matching and isolation transformers ⊕ LAN common mode chokes ⊕ Power supply common mode chokes ⊕ Inductors ⊕ Current sensing transformers ⊕ DC-DC converters ⊕ Telecommunications transformers ⊕ Telecommunications chokes ⊕ CAN-Bus Chokes ⊕ Lighting Ballasts ⊕ Ground Fault Interuptor Applications ⊕ EMI filters
Features:
Steward 35 and 40 material ferrite toroids provide low losses and high performance in transformers at kHz to low MHz frequencies
Steward 35 and 40 material ferrite toroids provide high impedance below 10MHz for suppression of undesired signals
Steward 28 material ferrite toroids provide high impedance from 10MHz to over 500MHz
