This Product Selection Guide contains information to help select products in the Delay Lines category on DigiKey.com
A delay line is a discrete surface or through-hole mount device that allows a signal to be delayed by a fixed time interval. Delay lines are widely used building blocks in methods to simulate room acoustics, musical instruments, audio effects, and are used to help solve TTL, and ECL timing and clock skew issues. They are differentiated by fixed delay times from 40 ps to 22.6 ns.
SelectionCharacteristics
Delay Time: Characterizes the amount of propagation delay imposed by a device on signals passed through it, under manufacturer-defined test conditions.
Tolerance: Characterizes the extent of permitted variability of overall delay time among samples of a given part number, resulting from variations in manufacturing.
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.
