Additional Details:

The KDV202E-RTK/P varicap diode's performance is defined by its capacitance variation with reverse voltage. The 'RTK/P' suffix typically indicates a specific packaging and tape/reel format for automated assembly. The high capacitance ratio is a critical parameter, determining the extent to which the frequency can be tuned in an oscillator or filter circuit. The low series resistance enhances the Q-factor of the tuned circuit, contributing to better signal clarity and stability. This diode is essential in modern communication devices, instrumentation, and radio frequency (RF) systems where precise frequency control is paramount. Designers often select this component for its reliability and performance in demanding tuning applications.
