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 +100°C
Inductance Tolerance:
±10%
Testing:
Inductance is tested on an HP4284A at 1.0 kHz
Packaging:
