The Smalley SSB-0138 wave spring is a precision-engineered electrical component designed for applications requiring reliable axial force in compact spaces. Manufactured from high-quality spring steel, this wave spring features an outer diameter of 13.8 mm, an inner diameter of 11.4 mm, and a thickness of 0.2 mm, with a free height of 1.0 mm and a solid height of 0.6 mm, making it ideal for tight assemblies. It delivers consistent load characteristics and excellent fatigue resistance, suitable for both static and dynamic environments. While not a capacitor, its robust construction ensures stable performance in electrical connectors, switches, and other precision mechanisms where space savings and repeatable force are critical.
