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 addin a “T” sux
to the part number( i.e. P0841SNL becomes P0841SNLT). Pulse complies to industry
standard tape and reel specification EIA481.
5. 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.
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.
