62 OHM 25W HOLLOW CORE POWER WIREWOUND RESISTOR TRU-OHM RW33V620

Enamel-coated resistors, typically of the wirewound type, feature a resistive element wound around a ceramic core and protected by a durable outer layer of vitreous enamel (a form of glass glaze). This coating provides robust protection against mechanical damage, moisture, and harsh environmental conditions.

Key characteristics and functions:
Durable Protection The vitreous enamel coating is impervious and non-burning, offering excellent long-term stability and reliability in demanding environments.
High Power Dissipation
These are typically power resistors designed to handle significant power loads and high temperatures, often in applications such as braking systems, in-rush limiting, and industrial machinery.
Heat Resistance
The enamel can withstand high operating temperatures. The core, often made of a high-purity ceramic, helps manage and dissipate heat effectively.
Good Insulation when cold, the enamel provides excellent electrical insulation. Overall, enamel-coated resistors are highly stable, robust components used in applications requiring high power capacity and reliable performance under challenging thermal and environmental conditions.
