environmental applications

Operating temperature range: -40°C – +125°C (the self-temperature rise is contained)

Allowable current is a DC Current which causes initial inductance to decrease by 10%. Or coil temperature to rise by 40°C, whichever is smaller

Surface Temperature Rise graphs and additional environmental applications can be found at www.koaspeer.com
