4681 Description

Short technical summary and product information.

The Keystone Electronics 4681 is a circular insulator made from mica, designed for general purpose insulation applications. With a diameter of 4.98mm (0.196 inches), this component provides reliable electrical isolation in a compact form factor.

 

Mica offers excellent dielectric strength and thermal resistance, making it suitable for use in high-temperature environments where plastic insulators may degrade. The circular shape allows for easy integration into standard mounting holes or standoff configurations.

 

This insulator is intended for use in hardware, fasteners, and accessories categories, specifically for component insulation and spacing. It is RoHS3 compliant and has an MSL rating of 1 (unlimited), indicating no moisture sensitivity concerns during handling and storage.
