Crystals operate over extended -55C to +125C temperature range

FOX HC49 line of low-cost resistance weld crystals includes two versions that maintain stability and tolerances across an extended temperature range of -55C to +125C. The SMD HC49SDLF and thru-hole HC49SLF provide frequencies from 3.2MHz to 80MHz in the same compact 14mm x 5mm package with maximum heights of 4.5mm and 3.6mm, respectively. Both new crystals feature frequency tolerances as low as ±10 ppm at 25°C and frequency stabilities as tight as ±90ppm from -55C to +125C.
