Determine which wire carrying the signal or power is susceptible to or causing EMI/RFI. This could be a power cord, a signal cable, or a wire within a circuit board assembly. — Identify the wire to filter 2. Carefully pass the identified wire through the center opening of the Fair-Rite FT50-43 toroid core. For increased effectiveness, wind the wire multiple times through the core; more turns generally result in higher impedance. — Wind the wire through the core 3. Place the toroid core near the source of interference or the point where filtering is most needed. Secure it in place using zip ties, heat shrink tubing, or adhesive if necessary to prevent movement. — Position and secure the core ## Product details | Field | Value | |---|---| | Ferrite Material Type | 43 | | AL Value | 440 µH/100 turns | | Frequency Range | 20 MHz - 250 MHz | | Primary Use | EMI/RFI Suppression | | Application Type | Electronic Circuits, Noise Filtering | | Installation Type | Winding Wire Through Core | | Cost per unit | {{ccc_price_per_unit:1:core}} | | Brand | Fair-Rite | | Model Name | FT50-43 | | Part Number | FT50-43 | | Material | 43 Ferrite | | Color | Multicolored | | Outer Diameter | 0.500 inches (12.7 mm) | | Inner Diameter | 0.281 inches (7.14 mm) | | Height | 0.188 inches (4.78 mm) | | Item Weight | 1 ounce (28.35 g) | | Package Weight | 0.018 kilograms (0.63 ounces) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### What is the primary function of the Fair-Rite FT50-43 ferrite toroid core? The primary function of the Fair-Rite FT50-43 ferrite toroid core is to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in electronic circuits. It acts as a filter, reducing unwanted noise across a frequency range of 20 MHz to 250 MHz, thereby improving the performance and reliability of electronic devices. ### What are the dimensions of the FT50-43 ferrite toroid core? The FT50-43 ferrite toroid core has an outer diameter of 0.500 inches (12.7 mm), an inner diameter of 0.281 inches (7.14 mm), and a height of 0.188 inches (4.78 mm). These precise measurements allow for easy integration into various electronic assemblies and winding applications. ### What is the AL value and material type of this ferrite core? The FT50-43 ferrite toroid core is made from 43 ferrite material and has an AL value of 440 µH/100 turns. This specific material composition and AL value are optimized for effective noise suppression in the specified frequency range. ### How does this ferrite core help in reducing electronic noise? This ferrite core helps reduce electronic noise by acting as an inductor when wire is wound through it. It presents a high impedance to high-frequency noise signals, effectively absorbing or reflecting them away from the circuit, thus cleaning up the signal path. ### Is this ferrite core suitable for high-frequency applications in India? Yes, the FT50-43 ferrite toroid core is designed for EMI/RFI suppression in the 20 MHz to 250 MHz range, which covers many high-frequency applications relevant in India.
