Inductance values may vary 20%. 7. The temperature of the component (ambient plus temperature rise) must be within 2. ETop rated at 260kHz. the stated operating temperature range. 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 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 necesssarily 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.
