Notes: 1) The prices shown below are for sample quantity. Please call 800-377-3244 or email sales@coilws.com for larger volume OEM pricing. 2) Our large OEM pricing is extremely competitive. 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) "Inductance at 1 Khz" ( 2nd column from left in table below ) is the inductance measured at zero or very low DC bias current. 6) "Current Rating" ( 3rd column from left in table below ) is based on a 40 deg C temperature rise at an ambient temperature of 90 deg C. This is the DC bias current through the inductor that will cause the inductor will reach a max. temp. rise of 40 deg C. above ambient with NO AIR FLOW. 7) "Incremental Current for 20% inductance drop" ( 4th column from left in table below ) is the DC bias current that will cause the inductance to drop by 20% from the value shown in Inductance at 1 Khz. At this current, the temperature rise may be above the 40 deg C stated above, so forced air flow may be required. 8) The saturation current is at least 5 times the max current listed in 5) or 6) above, so instantaneous high current spikes can be tolerated by these inductors. 9) Dimensions: A = Length, B = width, C = height  |
