Notes
5. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to
the part number (i.e. PA0273NL becomes PA0273NLT). Pulse complies
with industry standard tape and reel specification EIA481. The tape and
reel for this product has a width (W=44mm), pitch (Po=32mm) and depth
(Ko=11.78mm).
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.

1. The temperature of the component (ambient plus temperature rise) must
be within the stated operating temperature range.
2. The above transformers and inductors have been tested and approved
by Pulse's power IC partners and are sited in the appropriate datasheet
or evaluation board documentation at these companies. To determine
which IC and IC partners are matched with the above Pulse part numbers please consult the IC Cross Reference on the Pulse website.
3. For flyback topology applications, it is necessary to ensure that the transformer will not saturate in the application. The peak flux density (Bpk)
should remain below 2700Gauss. To calculate the peak flux density use
the following formula:
Bpk (Gauss) = K1_Factor * Ipk(A)
4. In high volt-µsec applications, it is important to calculate the core loss of
the transformer. Approximate transformer core loss can be calculated as:
CoreLoss (W) = 1.32E-13 * (Freq_kHz)1.63 * (ΔB_Gauss)2.63
where ΔB can be calculated as:
For Flyback Topology: ΔB = K1_Factor * Δ(A)
For Forward Topology: ΔB = K1_Factor * Volt-µsec
