To calculate the peak flux density for a uni-polar current use the following formula: B PK = 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. PB0025 becomes PB0025T). Pulse complies to industry standard tape and reel specification EIA481. 6. RoHS compliant parts are being introduced. Please contact Pulse for RoHS compliant part availability. If available, order part by adding “NL” to part no. (i.e. PB0025 becomes PB0025NL and PB0025T becomes PB0025NLT).
