F-3551 Datasheet, PDF (1/2 Pages) Rhombus Industries Inc. – Very Low Profile Tax Filters

Very Low Profile Tax Filters
Attenuates 12 or 16 kHz signals to
telco equipment by more than 25 dB.
Uses standard-value capacitor for either
12 or 16 kHz resonance
Designed to provide 25 dB minimum
attenuation at 12 or 16 kHz.
