Fox Electronics recently introduced two new series of ceramic SMD (surface mount device) automotive-grade crystals built to operate at extended temperature ranges and engineered to withstand higher levels of shock and vibration. The FXA5032B and FXA7050B crystals are used in a variety of automotive timing applications, including GPS navigation, high-end audio and video systems, wireless phones, collision warning systems, Antilock Brake System controller, RADAR and onboard computer systems. The FXA5032B series features a 5 mm x 3 mm package with a frequency range of 8 MHz to 150 MHz, while the larger 7 mm x 5 mm FXA7050B series offers a 6 MHz to 133 MHz frequency range. Standard frequency stabilities for both series are ±50 ppm to ±100 ppm, with operating temperatures ranging from -40°C to +85°C and -40°C to +125°C, respectively and a 3 ppm aging per year.
