NOTES:
1.The temperature of the component (ambient temperature plus temper-
ature rise) must be within the specified operating temperature range.
2.The maximum current rating is based upon temperature rise of the
component and represents the DC current which will cause a typical
temperature rise of 40°C with no airflow when both one turn windings
connected in parallel.
3.To calculate the value of the terminating resistor (Rt) use the following
formula: Rt (Ω) = VREF * N / (Ipeak_primary)
4.The peak flux density of the device must remain below 2000 Gauss.
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.
PB0025
becomes
PB0025
T). 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
PB0025
NL and
PB0025
T becomes
PB0025
NLT).
