Saturation current: This indicates the actual value of D.C. current when the inductance becomes 30% lower than its initial value. 3 Temperature rise current: The actual value of D.C. current when the temperature of coil becomes T=40C (Ta=20C). 4. Measurement condition: Irms testing was performed by a product in 20C ambient. 5. Measurement condition: Irms testing was performed on copper traces in 20C ambient. Discharge static electricity before handling this coil. Take the static electricity measures to prevent deterioration of electric characteristic Note This specification is subject to change without notice.
