# ABLS-4.897MHZ-20-R70-D-T (Component) ## Description 4.897 MHz Surface-Mount Quartz Crystal – AT-cut fundamental-mode quartz crystal designed for microcontrollers, wireless modules, communication equipment, industrial control systems, timing circuits, embedded electronics, and IoT devices. Part of the Abracon ABLS Series, it provides a 4.897 MHz operating frequency with ±50 ppm frequency tolerance, ±50 ppm frequency stability, 20 pF load capacitance, and 70 Ω maximum ESR for reliable clock generation. Features a 100 µW typical drive level (1 mW max), HC-49/US low-profile SMD package, and fundamental resonance mode for stable oscillator performance. Designed for surface-mount assembly, it operates over a −40°C to +85°C temperature range and is suitable for general-purpose embedded and industrial timing applications. #Abracon #ABLS4897MHZ20R70DT #QuartzCrystal #49MHzCrystal #ClockCrystal #TimingDevice #HC49US #SMDCrystal #Microcontroller #IndustrialElectronics #EmbeddedSystems ## Component Details - **Owner:** silicon-yard - **Created:** 8/3/2026 - **Last Updated:** 8/3/2026 - **Visibility:** Public - **Manufacturer Name:** Abracon - **Manufacturer Part Number:** ABLS-4.897MHZ-20-R70-D-T - **Datasheet URL:** https://abracon.com/Resonators/abls.pdf - **Part Type:** Oscillator - **Used in:** 1 project - **Part Type:** Crystals and Oscillators - **Manufacturer:** Abracon - **MPN:** ABLS-4.897MHZ-20-R70-D-T - **Mount Type:** Surface Mount - **Package / Case Code:** CRYSTAL-SMD - **Pin Count:** 2 ## Pins | Pin | Name | Type | |-----|------|------| | 1 | 1 | | | 2 | 2 | | --- *Generated from [https://www.flux.ai/silicon-yard/abls-4p897mhz-20-r70-d-t](https://www.flux.ai/silicon-yard/abls-4p897mhz-20-r70-d-t)*
