Hi. I need one of these for the primary side of a LeCroy power supply. Been looking at RS Components, Radio Parts and Element-14/Farnell without success. I think the one installed is perhaps metal oxide/flameproof type - green body & matt finish. From the size I think 2W (it's 9mm x 3mm in the body) Any suggestions? I can find them online in US/Canada but postage is high. Also ex China/Hong Kong with free postage but unknown quality. Grateful tips as to what to avoid/prefer.
