Notes :
1.
Inductance values may vary ±20%.
2.
ETop rated at 260kHz.
3.
SIMPLE SWITCHER™ is a trademark of National Semiconductor
Corporation.
4.
For SMT parts, optional Tape & Reel packaging can be ordered by adding
a "T" suffix to the part number (i.e. P0841SNL becomes P0841SNLT).
Pulse complies to industry standard tape and reel specification EIA481.
5.
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.
6.
Series connection (pins 2-4 connected)
7.
The temperature of the component (ambient plus temperature rise) must
be within the stated operating temperature range.
