1. Inductance values may vary ±20%.
2. ETop rated at 150kHz except where designated.
3. ETop rated at 100kHz.
4. SIMPLE SWITCHER™ is a trademark of National Semiconductor Corp.
5. For SMT parts, optional Tape & Reel packaging can be ordered by addin a “T” sux to
the part number (i.e. PE-53801SNL becomes PE-53801SNLT). Pulse complies to industry
standard tape and reel specification EIA481.
6. The “NL” sux indicates an RoHS-compliant part number. Non-NL suxed parts are
not necesssarily RoHS-compliant, but are electrically and mechanically equivalent to
NL versions. If a part number does not have the “NL” sux, but an RoHS compliant
version is required, please contact Pulse for availability.
7. The temperature of the component (ambient plus temperature rise) must be within
the stated operating temperature range.
* Contact Pulse for availability
