  • High termination strength and reliable

Rated 3 out of 5 by from Picture not matching item in store - different charachteristics I just picked this item up from Maidenhead - after paying for it online. The inductor in the picture shows Green 100uH 10% Tolerance (Silver band) which is what I wanted. At the store they gave me a beige version with 100uH 5% Tolerance (Gold band) and said they've changed supplier. Sounds like they don't know the difference between 5% and 10%. Perhaps somebody buys a 10v battery and gets a 5v battery - what would you say then ? MAPLIN needs to fix issues like this and update their website pictures and descriptions. Some VERY information is missing from many items.
