NOTES:
1. The temperature of the component (ambient plus temperature rise) must be within
the specified operating temperature range.
2. Inductance at Irated is typical inductance value for component taken at rated current.
3. The rated current listed is the lower of saturation current @ 25°C or heating current.
4. The saturation current, Isat, is the current at which the component inductance drops
by 10% (typical) at an ambient temperature of 25°C. This current is determined by
placing the component in the specified ambient environment and applying a short
duration pulse current (to eliminate self-heating effects) to the component.
5. The heating current, I
DC
, is the DC current required to raise the component
temperature by approximately 40°C. The heating current is determined by mounting
the component on a typical PCB and applying current for 30 minutes.
6. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the
part number (i.e. PB2020.102NL becomes PB2020.102NLT). Pulse complies to
industry standard tape and reel specification EIA481.
7. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed
parts are not necessarily 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.
