To calculate the peak flux density for a uni-polar current use the following formula: BPK = 8.0 * VREF * (Duty_Cycle_Max) * 105 / ( N * Freq_kHz) * for bi-polar current applications divide BPK as calculated above by 2. 5. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PB0025NL becomes PB0025NLT). Pulse complies to industry standard tape and reel specification EIA481. 6. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not have the "NL" suffix, but an RoHS compliant version is required, please contact Pulse for availability. Height: 10.2mm Max Footprint: 19.9mm x 14.5mm Max Current Rating: up to 35A Frequency Range: 50kHz to 500kHz
