Ideal for "Set and Forget" applications Multi-turn adjustment screw (1503: 40 turns, 1503J: 60 turns) Stackable for PC board economy x 10mil flat leads (1503) #20 gauge leads (1503J) Resolution: As low as 0.12ns Dielectric breakdown: 50 Vdc Temperature coefficient: 100 PPM/�C
The 1503- and 1503J-series devices are mechanically variable, passive delay IN Signal Input lines. The signal input (IN) is reproduced at the tap output (TAP), shifted by an TAP Variable Output amount which can be adjusted between 0 and TD, where TD is the device dash OUT Fixed Output number. The fixed output (OUT) reproduces the input, delayed by TD, and must GND Ground be terminated to match the characteristic impedance of the line, which is given by the letter code that follows the dash number (See Table). The tap output is unbuffered. The 3dB bandwidth of the line is given 3.5 / TR, where TR is the rise time of the line (See Table).
INPUT: Ambient Temperature: Input Pulse: 25 High = 3.0V typical Low = 0.0V typical Source Impedance: 50 Max. Rise/Fall Time: 3.0 ns Max. (measured at 10% and 90% levels) Pulse Width (TD 75ns): PWIN = 100ns Period (TD 75ns): PERIN = 1000ns Pulse Width (TD > 75ns): PWIN x TD Period (TD > 75ns): PERIN x TD
NOTE: The above conditions are for test only and do not in any way restrict the operation of the device.
