Frequently Asked Questions
Q: Does this RX20-ZG11 wire-wound resistor come with a mounting bracket?
A: No — this listing includes the resistor only (1 piece). The compatible RX20-ZG11 mounting bracket is sold separately in our store and must be purchased as an additional item.
Q: What resistance values are available for the RX20-ZG11 30W and 50W resistors?
A: The RX20-ZG11 is available in a wide range of resistance values including 1R, 2R, 5R, 10R, 20R, 25R, 30R, 50R, 100R, 150R, and up to 50KΩ. Please select your desired value from the product variant options before adding to cart.
Q: What are the typical applications for a high-power vitreous enamel wire-wound resistor?
A: High-power wire-wound resistors like the RX20-ZG11 are commonly used in power electronics, motor control circuits, load banks, audio amplifier builds, industrial automation panels, and test bench equipment where high wattage dissipation and precise resistance are required.
Q: How does the vitreous enamel coating benefit the RX20-ZG11 resistor?
A: The vitreous enamel coating provides a hard, heat-resistant outer shell that improves thermal dissipation, protects the internal wire winding from moisture and mechanical damage, and extends the operational lifespan of the resistor in high-power environments.
