The Raltron Electronics AS-4.000-18-SMD-TR is a fundamental mode quartz crystal with a nominal frequency of 4 MHz. It is designed for surface mount assembly in a compact HC-49/US package measuring 12.00mm x 4.80mm with a height of 4.60mm.
Electrical specifications include a load capacitance of 18 pF, maximum equivalent series resistance of 130 Ω, and a drive level of 100 µW typical / 500 µW maximum. Frequency tolerance is ±30 ppm at 25°C, and frequency stability over the full operating temperature range of -20°C to +70°C is ±50 ppm maximum. The crystal also features a shunt capacitance of 5 pF maximum and aging of ±5 ppm per year.
The component is RoHS, REACH SVHC, and Halogen-Free compliant with a moisture sensitivity level of MSL 1. Termination finish is tin (Sn). It is supplied on tape and reel (24mm tape width, 12mm pitch) with 1000 pieces per 178mm diameter reel, suitable for automated pick-and-place assembly.
