Actual temperature of the component during system operation (ambient plus temperature rise) 3. must be within the standard operating range. - The Rated Current is the DC current required to raise the component temperature by the value shown. Take note that the component’s performance varies depending on the system condition. It is suggested that the component be tested at the system level, to verify the temperature rise of the component during system operation. 2. The Saturation Current is the current at which the initial inductance drops approximately by the amount shown at the stated ambient temperature. This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effect) to the component. 4. The inductance tolerance of the .104NLT / .154NLT / .334NLT / .474NLT / .564NLT / .684NLT / .105NLT and .155NLT are ± 10% all other values are ±20%. ## **Mechanical** ## **Schematic** ## **PA4320.XXXNLT** power.pulseelectronics.com http://www.power.pulseelectronics.com/contact P787.D (04/19) 1 ##

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
