Power Line Chokes - Axial SPECIFICATIONS CTH8VF Series From 3.9 µH to 100,000 µH Not shown at actual size. RoHS Compliant CHARACTERISTICS Description: Axial leaded power line inductor (clear varnish coated) 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: Bulk pack standard, Tape & Reel available. Lead length (dimension C) is 15mm max. for parts packaged tape & reel. Marking: Marked with color dots Saturation Current: Lowers inductance by 5% Bobbin: High saturation, allows for high inductance with low DC resistance Miscellaneous: RoHS Compliant. Higher current parts available Additional Information: Additional electrical & physical information available upon request Samples available. See website for ordering information. ctparts.com Parts are available in ±10% tolerance only Part Number Inductance (µH) L Test Freq. (kHz) SRF Min. (MHz) DCR Max.
