AMIDON BN-43-2402. The two-hole multi-aperture core is commonly used for wideband transformers and impedance matching devices. The primary concern, when designing a wideband transformer, is to extend the bandwidth with a minimum of loss. The limiting factors are inductive reactance and core loss. By winding through both holes of the binocular type two hole core, a higher inductance per turn can be obtained than would be possible with a single hole core. Material 43 (µ = 850) Has High volume resistivity. For medium frequency inductors and wideband transformers up to 50 MHz. Optimum frequency attenuation from 40 MHZ to 400 MHz. 43 Ferrite Material Magnetic Properties: Initial Perm. ~ 850; Maximum Perm. ~ 3,000; Maximum Flux Density @ 10 oer, (gauss) ~ 2,750; Residual Flux Density, (gauss) ~ 1,200; Vol. Resistance (Ohms-cm) ~ 10,000; Temp. Coeff. -20°C ~ 70°C (%/°C) ~ 1.0%; Loss Factor ~ 0.00012 @ 0.1 MHz; Coercive Force (Oersteds) ~ 0.30; Curie Temp. (°C) ~ 130°C; Resonant Cir. Freq. (MHz) ~ 0.01 to 1 MHZ; Wideband Freq. (MHz*) ~ 1 to 50 Mhz; Attenuation RF Noise, (MHz) 30 to 200 MHz. *Based on low power, small core application. Listed frequencies will be lower with higher power.
