0402 CHIP INDUCTORS
Aerospace Grade Chip Inductors
AE235RAL
■
High current ratings – up to 1.8 A
■
Ideal for power amplifiers in TDMA, CDMA, GSM and
■
Outstanding self-resonant frequency
■
Tight inductance tolerance
■
High temperature materials allow operation in ambient
other wireless applications
■
Perfect for use as an RF choke for the power supply, the
LC tank between amplifier and antenna and in the
amplifier bias circuit.
■
Excellent Q factors
temperatures up to 155°C.
■
Passes NASA low outgassing specifications
■
Leach-resistant base metalization with tin-lead (Sn-Pb)
terminations ensures the best possible board adhesion
