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” sux to
the part number (i.e. PE-53801SNL becomes PE-53801SNLT). Pulse complies to industry
standard tape and reel specification EIA481.
6. The “NL” sux indicates an RoHS-compliant part number. Non-NL suxed parts are
not necesssarily RoHS-compliant, but are electrically and mechanically equivalent to
NL versions. If a part number does not have the “NL” sux, 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.
