NOTES:
1.The peak flux density of the component should be kept below 3400 Gauss
(25°C) and 2900 Gauss (100°C). To calculate the peak flux density in a given
application, use the following formula:
Bpk (Gauss) = K1_Factor * Iprimary_pk
2. Leakage inductance is measured at primary terminals with all secondaries shorted.
3.Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the
part number (i.e. PA0648NL becomes PA0648NLT). Pulse complies to industry
standard tape and reel specification EIA481.
4.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.
5.The temperature of the component (ambient plus temperature rise) must be within
the stated operating temperature range.
