ECX-1637B SMD Crystals

ECS ECX-1637B SMD Crystals are available in a subminiature ceramic package measuring 2.0mm x 1.6mm x 0.45mm. These crystals feature low first-year aging of ±1ppm or ±2ppm maximum, a 16MHz to 96MHz frequency range, and 3pF shunt capacitance. This series is RoHS compliant and offers extended temperature range options. ECS ECX-1637B SMD Crystals are ideal for wireless applications, including the Internet of Things (IoT), medical, Wi-Fi®, and BLUETOOTH®.
