ECS-33B SMD Crystals

ECS ECS-33B SMD Crystals feature a 3.2mm x 2.5mm x 0.8mm ceramic package with low first-year aging of ±1ppm maximum. These crystals have a 10MHz to 54MHz frequency range for wireless applications. Other features include high reliability and improved stability, fundamental mode of oscillation, and 200μW drive level. ECS ECS-33B SMD Crystals are ideal for the Internet of Things (IoT), smart home sensors, BLUETOOTH® Low Energy, Wi-Fi®, and wearable applications.
