Bourns 071923 & 093267 EMC Filter Chokes

Bourns 071923 SP-E 13/4 and 093267 SP-E 16/5 EMC Filter Chokes are characterized by a wide-band performance of interference suppression with excellent attenuation of symmetric and asymmetric noise. These chokes feature a compact design that complies with EN 62368 and RoHS requirements. Both series offer a 1:1 transformation ratio and a -25°C to +125°C operating temperature range. The 071923 choke features 2 x 22mH nominal inductance, 3Ω maximum resistance per winding, and 0.28A nominal current. The 093267 module offers 2 x 27mH nominal inductance, 2Ω maximum resistance per winding, and 0.5A nominal current. Bourns 071923 SP-E 13/4 and 093267 SP-E 16/5 EMC Filter Chokes are ideal for applications such as low-power switched-mode power supplies (SMPS), drives and control circuits, industrial applications, and home appliances.
