Crystal resonator
The H49U and H50U series are the resistance-weld version of the old solder seal types HC-18U and HC-25U respectively. They are physically interchangeable.
No solder or flux involved in the sealing process.Low aging.
HC-49U is wire lead type and HC-50U is plug-in type.
Two different holder heights available: 13.6mm and 11.2mm
