A Chebyshef lowpass with a cutoff at 12 KHz

I'm looking to make this:

For smoothing a sinwave as per this project: http://interface.khm.de/index.php/lab/experiments/arduino-dds-sinewave-generator/

I'm checking if I'm about to get the correct inductor as i've never used them before, in whcih case would this one be OK: http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=4889986

Thankyou clever people.
