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 num-
bers please consult the IC Cross Reference on the Pulse website.
3. For flyback topology applications, it is necessary to ensure that the trans-
former 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) = 2.98E-13 * (Freq_kHz)
1.63
* (DB_Gauss)
2.63
where
DB
can be calculated as:
For Flyback Topology:
DB
= K1_Factor *
D(A)
For Forward Topology:
DB
= K1_Factor * Volt-µsec
5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to
the part number (i.e. PA0700NL becomes PA0700NLT). Pulse complies
with industry standard tape and reel specification EIA481.
6. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suf-
fixed 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 con-
tact Pulse for availability.
