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. PB2020.102 becomes PB2020.102T). Pulse complies to industry
standard tape and reel specification EIA481.
7. To order RoHS compliant part, add the suffix “NL” to the part number
(i.e. PB2020.102 becomes PB2020.102NL and PB2020.102T becomes
PB2020.102NLT).
