Know before you buy
The vitreous enamel coating provides a rugged, moisture-resistant barrier that protects the internal wirewound element. This makes the resistor particularly well-suited for industrial environments where humidity or environmental contaminants might otherwise compromise performance.
Yes, this resistor is rated for an operating temperature range of +25°C to +350°C. Its flame-retardant construction ensures it remains safe and stable even when operating at these elevated temperatures.
This resistor has a maximum voltage rating of 720 V. Ensure your circuit design does not exceed this limit to maintain the integrity and safety of the component.
The all-welded construction eliminates mechanical weak points often found in crimped or soldered connections. This design choice significantly enhances the component's durability and long-term reliability under thermal stress.
A 5% tolerance indicates that the actual resistance value may vary by up to 5% from the nominal 1 kOhm rating. This is a standard tolerance for general-purpose power management applications where extreme precision is not the primary requirement.
