Common Mode Chokes

Common Mode Chokes are miniature and do not require external components for their operation. They can effectively filter out electromagnetic interference (EMI) from the power supply lines of electronic systems. The most common type of common mode choke is the ELF-25F112A. The ELF-25F112A is a direct-current- operated, multi-turn, common mode choke with a total inductance of 0.63 mH. It\'s ideal for applications with more than 5V of operation voltage and a current range of 0.55A to 0.74A. It\'s constructed from a robust stainless steel core and two high-performance wire-wound conductors. Due to its compact design, the ELF-25F112A can be small enough to fit inside most handheld devices. The ELF-25F112A is an industry-standard part and is designed for filtering purposes, specifically to reduce spikes and EMI. It is ideal for use in contactless readers/writers, automotive electronic systems, touchscreens, and communication systems. Its several features, such as high current density, low resistance, and low electrical losses, make it a popular choice in today\'s miniature circuit designs. The ELF-25F112A works via magnetic flux, which is generated by current passing through the two conductors. This magnetic flux, in turn, creates an inductance and impedes disruption. This limits any spikes or EMI on the power supply line.The ELF-25F112A is a low-cost, effective, and efficient solution for controlling EMI. Its miniature design makes it perfect for most application fields, including the automotive industry, medical instruments, smart meters, and wireless charging circuits. The ELF-25F112A is also UL94V-0 rated and has a current rating of up to 0.74A and an inductance of up to 0.63 mH. In summary, the ELF-25F112A is a reliable and cost-effective solution for filtering EMI in various application fields. It is a miniature common mode choke with a current range of up to 0.74A and an inductance of up to 0.63 mH. It is constructed from a robust stainless steel core with two high-performance wire-wound conductors. Its UL94V-0 rating and low electrical losses make it a great choice for filtering purposes.
