API Delevan’s combination of high performance Ni-Zn cores and
low capacitance type windings allow for superior frequency
characteristics.
• Only small scattered fields are generated by the windings
• Ensures excellent attenuation characteristics over a wide
frequency range
• Packaged in a flat-top (UL94V-O) header, compatible with auto
insertion equipment
Typical Applications
Data line filters; audio signal filters; current
supply choke; video signal filters.
• Sample kit available
Notes
* 1.
Insulation Voltage (VDC) is one minute line to case;
inductance measured at 1kHz/1V
2.
Impedance measurement using HP4191A
impedance analyzer.
