Introduce of DR cores

DR core, as a kind of NiZn cores, its center hole is for mechanical mounting. With various types of ferrite cores for covering wide inductance range, DR core is provided with outstanding frequency characteristics and a high Q value at high frequencies. The low DC resistance permits high current flow. The DR core has excellent solder heat resistance.

Features of DR cores:

DR cores are provided with many features, such as high Saturation; Pre-Tinned Leads; Broad range of inductance values: 0.8 - 1000 H; From low to high currents: 0.1 - 30 Amps; Small PCB space, in 5 standard sizes. DR core has very stable inductance over current range and class B (130C) insulation system. The available materials can be changed according to your request. Other sizes and values are available.

Applications of DR cores:

IFI OSCIL ATE COLI, Various filter delay line inductor, Power Amplifiers, Filters Power Supplies, SCR and Triac Controls, Speaker Crossover Networks, RFI Suppression, Video equipment, Portable audio-visual equipment. Choke coils, Cellular mobile phone, pagers, radio communication equipment, etc.
