Notes:
1 ) The prices shown below are for low volume quantity. Please call 800-377-3244 or 
email sales@coilws.com for larger volume OEM pricing.
2 ) Our large OEM pricing is extremely competitive. Very high volume pricing is under $1 each, tape and reel packaging. We will meet or beat any competitors prices with better deliveries
3 ) Custom designs are available to meet any of your requirements. Please contact us
4 ) The data shown below can be sorted by clicking each column header.Click once again to sort in reverse order.
5) Rated current is based on a 40 deg C temp rise above the ambient, up to a max component temp of 110 deg C. Ferrite curie temp is over 200 deg C and wire insulation is rated at 200 deg C. 
6) Theta JA, Theta JC, Rja and Rjb used in simulation softwares are only applicable for active devices, such as integrated circuits, etc. Inductors such as this CWS series do not use any semiconductor material and do not have same potential failure modes. The junction temperature gradient in CWS inductors are almost zero since it is a continuous copper wires.
