ABM13W IoT Optimized Ultra-Miniature Crystals Abracon ABM13W IoT Optimized Ultra-Miniature Quartz Crystals are ideal for space constraint applications. The small, low profile At-Cut MHz crystals (1.20mm x 1.00mm x 0.33mm package) feature a low ESR ranging from <,25Ω to 100Ω over a 32MHz to 80MHz frequency range. The crystals are available in several load capacitance values (5pF to 8pF) and several temperature options. Other features include simultaneous optimization for low plating loads, enhanced performance for start-up times, and power savings with Low Energy SoC’s. ABM13W crystals are ideal for IoT, wearables, and wireless applications.
