Resistor with pulsed load.

Hello
We need a load resisrtor of 10 Ohms which will dissipate 62W. However, this is a pulsed load, and in fact the resistor dissipates several kW’s just for a few milliseconds, every 0.6 seconds.
The pdf schematic and LTspice simulation of the circuit where the resistor is used is attached.
Do you think the following resistor is OK for this highly pulsed loading?....

It's all in the datasheet, see the pulse load diagram.

Sorry my fault. I was looking at the Welwyn WH series datasheet, which is also linked on the Farnell product page

Due to similar design, you can probably use it as an estimation of Arcol data.
