RCA-THT 75 x 15 x 6.3 mm The Signal IF Receiver Antennas Radio Clock Receiver Antenna Trough-hole Features This component is a radio clock receiver antenna in Through-holte technology to allow an improved method of fixation to the PCB of the electronic device that uses it. There are several clock signal transmiter in different countries: DCF-77.5kHz (Germany), HBG-75kHz (Switzerland), MSF-60kHz (United Kingdom), DTDF-162F (France), JJY40&60kHz (Japan), WWB-60kHz (USA). The component is configured as L-C resonant parallel tank. The module antenna is formed by ferrite core wound and a ceramic capacitor inside a plastic housing and it filled with polyurethane resin. Characteristics - Through-hole mounting in 75mm x 15mm x 6.3mm size. - High stability in temperature (-20°C up to +85°C). - Designed for two tuning frequency (60kHz and 77.5kHz). - Higher resistance at resonance frequency. - Low variation of the resonance frequency with the temperature (±3% in a 20° to 105°C). - Good cost/performance ratio.
