Arcol 500Ω Ceramic Resistor 2.5W 250AS501KDS

High energy Axial leaded ceramic resistor for high peak power or high energy pulses. Maximum continuous operating temperature is 230°C. The resistor has a standard dielectric coating and silver metalized ends. Its construction acts to allow energy and power to be uniformly distributed throughout the entire ceramic resistors body.

100 & 200 Series Axial Leaded Non-Inductive Bulk Ceramic Resistors provide excellent performance where high peak power or high-energy pulses must be handled in a small size. The advantage of the bulk construction is that it produces an inherently non-inductive resistor and it allows energy and power to be uniformly distributed through the entire ceramic resistor body — there is no film or wire to fail. Three distinctly different ceramic materials are available in each size to afford the designer with unique components to meet the most demanding requirements. As alternatives to hard to find carbon composition resistors, composition resistors can be used as drop-in replacements for 1 and 2 watt sizes. Much larger sizes, up to 70 watts in a single component, are available for new or re-designs where an array of smaller resistors may have been previously required. Withstands high operating temperatures resulting in high power dissipation.
