1. The temperature of the component (ambient plus temperature rise)
must be within the stated operating temperature range.
2. The above transformers 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. Add 'T' suffix to the part number for Tape & Reel version
(ie: PA1130NLT).
4. The "NL" suffix indicates an RoHS-compliant part number. Non-NL
suffixed parts are not necessarily RoHS compliant, but are electri-
cally 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.
