CHARACTERISTICS
Description: Axial leaded power line inductor (UL sleeved)
Applications: Used in switching regulators, power amplifiers,
power supplies, SCR and Triac controls, speaker crossover
networks, RFI suppression and filters. Various applications
Operating Temperature: -55°C to +125°C
Inductance Tolerance: ±10%
Testing: Inductance is tested on an HP4284A at 1.0 kHz
Packaging: Tape & Reel standard, bulk packaging available.
Marking: Coils are sleeved in heat resistant polyolefin and
labeled with the part number
Miscellaneous: RoHS Compliant. Higher current parts available.
Saturation Current: Lowers inductance by 10%
Bobbin: High saturation, allows for high inductance with low
DC resistance
