Resonators Offer Built-In Load Capacitance

A line of leaded ceramic resonators feature a built-in load capacitance that eliminates the need for external capacitors associated with traditional filter design. No adjustment is needed and the oscillator will operate at the original frequency. A companion series of chip ceramic resonators comes with or without the built-in load capacitance feature. Both series operate over a frequency range from 1.8 to 50 MHz and in temperatures ranging from -20ûC to 80ûC. Frequency tolerances are up to ±0.5%. The components are reflow-solder compatible and are available in bulk or ammo packaging for the leaded devices and tape-and-reel for the chip components.
