This Product Selection Guide contains information to help select products in the Resonators category on DigiKey.com
Products in the resonator family are frequency selective elements used to generate a frequency source when used with an external drive circuit, similar to the manner in which quartz crystal devices are used but incorporating different technologies such as surface acoustic wave (SAW) or piezoceramic materials. Where their application spaces overlap with those of quartz crystals, resonator devices generally offer greater durability in exchange for reduced accuracy and output stability.
SelectionCharacteristics
Type: The construction methodology of the device, determining its intended usage and general behavior.
Frequency: The nominal rated frequency the device is specified to produce.
Frequency Stability: Characterizes output frequency variation due to temperature over a device’s rated operating temperature range, relative to the value measured at ~25°C.
Frequency Tolerance: Characterizes variability of resonant frequency among devices due to manufacturing variations, measured under standard test conditions.
Features: These are different capabilities or properties of the device such as built-in capacitor or without capacitor.
Capacitance: The capacitance value of the device’s integrated capacitor, if it has one.
Impedance: Identifies the effective resistance of the device to alternating current. It is comprised of resistance and reactance. It is measured in Ohm’s and uses the metric system for values.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier’s device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Size / Dimension: The physical dimensions of the device. Typically given in Length by Width, in Inches (Millimeters).
Height: Indicates how far the device will extend above the surface to which it has been attached.
