Overview
The ATS040B-E is a crystal made by CTS Electronic Components in a HC-49S package with 2 pins. -40℃~+85℃ 120Ω 18pF 4MHz ±30ppm ±50ppm HC-49S Crystals ROHS.
PCBKit's library has its KiCad symbol (Device:Crystal, from KiCad's library) and its footprint (EasyEDA_Cloud:CRYSTAL-TH_L10.8-W4.5-P4.88, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C1669726).
