X42 Surface Mount Crystal
(4 x 2.5 x 0.6mm)


Mercury now offers a small 4 pad ceramic leadless surface mount crystal package measuring 4 x 2.5 x 0.6mm that is both lead-free and RoHS compliant.

Our X42 series is available at frequencies ranging from 12.000MHz up to 50.000MHz with frequency stabilities as low as +/-5.0ppm from -20C to +70C and +/-10.0ppm over -30C to +85C using a fundamental AT-Cut crystal. Both series and parallel resonance are available with load capacitances (CL) from 10pF to 32pF.

This leadless crystal package is ideal for automatic pick & place machines for reducing assembly time. 1K piece tape and reel packaging is standard and it can withstand solder reflow twice at +260C for 10 seconds maximum or once at +230C for 180 seconds.

This series is popular for hand-held communication equipment, PDA’s, GPS, Bluetooth and media players because of very low aging and high shock & vibration resistance.
