Notes:
1. The temperature of the component (ambient temperature plus temperature 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 uni-polar current use 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 & Packaging can be ordered by adding a “T” suffix to the part number (i.e.
PB0025NL becomes PB0025NLT). Pulse complies to the 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.
