Product Description

The Roxburgh EMC SF1122 is a composite iron powder toroidal inductor specifically designed for electromagnetic interference (EMI) and radio frequency interference (RFI) suppression in electronic systems. With an inductance of 2.9 mH, this toroidal inductor is engineered to operate efficiently in phase angle control equipment and mains voltage circuits, commonly used in industrial and power electronics applications.

The product features a composite iron powder core, offering superior stability and consistent inductance across its operational temperature range. The toroidal configuration minimizes stray magnetic fields, making it ideal for environments where EMC compliance is critical. Its lead mount termination with stripped and tinned leads allows for reliable and straightforward installation onto printed circuit boards.

Designed with a maximum DC resistance of 500 mΩ, the SF1122 ensures low energy loss and optimal performance. The physical dimensions include a 32 mm diameter, 13 mm height, 40 mm length, and 0.56 mm lead diameter, resulting in a compact footprint suitable for modern PCB layouts. The inductor supports applications in control systems, filtering, and suppression of electrical noise.

Operating over a wide temperature range from -40°C to 125°C and featuring an inductance tolerance of 20 percent, the SF1122 meets UL standards and is ideally suited for installations that must comply with BS800 interference limits. Its robust construction ensures durability under demanding conditions, and the 5 mm lead pitch facilitates secure mechanical and electrical connections.

The Roxburgh EMC SF Series toroidal radial choke is particularly useful in industrial, automation, commercial, and power supply systems requiring stringent EMC performance. Use cases include phase angle control equipment, mains filtering, and RFI suppression in high-performance electronic assemblies.
