Bourns Releases High Current Common Mode Chokes

Model SRF3225TP Series

Riverside, California – January 5, 2024 – Bourns Magnetics Product Line is releasing the new Model SRF3225TP Series high current common mode chokes that offer a compact size and high impedance to suppress Electromagnetic Interference (EMI) coming into or leaving a system.

The RoHS compliant* and halogen free** Model SRF3225TP Series common mode chokes are designed to achieve a high current rating up to 2 A with impedance values ranging from 500 to 1000 ohms, which can decrease power consumption and improve EMI suppression in power lines. The operating temperature range is from -40 to +105 °C.

These chip-type, high current common mode chokes are compatible with high-density portable devices, and are ideal for power line noise countermeasures and EMI suppression in a variety of electronic devices.
