CTH7F Series

From 3.9 µH to 18,000 µH

Not shown at actual size.

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

Saturation Current: Lowers inductance by 10%

Bobbin: High saturation, allows for high inductance with low

DC resistance

Additional Information: Additional electrical & physical

information available upon request

Samples available. See website for ordering information.
