CTH8RF Series

Characteristics

Inductance Range: From 3.9 µH to 100,000 µH

Description: Radial 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: Bulk pack.

Marking: Coils are sleeved in heat resistant polyolefin and labeled with the part number.

Saturation Current: Lowers inductance by 5%.

Bobbin: High saturation, allows for high inductance with low DC resistance.

Miscellaneous: High current parts available.

Additional Information: Additional electrical & physical information available upon request.
