AIR CORE INDUCTORS
200°C Air Core Inductors
AT426RAT
AT446RAT
■Only 2 mm tall
■High Q over a wide range of frequencies
■Low DCR and excellent current handling capability
■Special materials allow operation in ambient temperatures
as low as –60°C and up to 200°C.
■Passes NASA low outgassing specifications
■Tin-lead (Sn-Pb) terminations ensure the best possible
board adhesion
