8Y SMD Seam Sealing Crystals TXC 8Y SMD Seam Sealing Crystals are extremely small ceramic crystal units with high precision and high-frequency stability, measuring 2.0mm x 1.6mm x 0.5mm. These quartz crystals feature excellent heat resistance and environmental characteristics and offer frequencies ranging from 16MHz to 66MHz with a 30ppm tolerance. 8Y crystal units operate from -20°C to +70°C with a 3pF maximum shunt capacitance. These RoHS-compliant, lead-free TXC crystal units are ideal for applications used in personal computers, digital cameras, PDAs, or tablets.
