7M SMD Seam Sealing Crystals TXC 7M SMD Seam Sealing Crystals are extremely small SMD-type crystal units with high precision and high-frequency stability, measuring 3.2mm x 2.5mm x 0.7mm. These quartz crystals are ideal for reducing electromagnetic interference (EMI) and are offered in frequencies ranging from 10MHz to 114.285MHz with a ±7ppm to ±30ppm tolerance range. The 7M crystal units operate in a -40°C to +85°C temperature range with an 8pF to 22pF load capacitance range and 3pF maximum shunt capacitance. These RoHS-compliant, lead-free TXC crystal units are ideal for wireless and BLUETOOTH® communication devices, including DSLR cameras and tablets.
