91MLA1200503R High Frequency Air-core Inductor, 12 Turns 17nH, 2-20GHz RF Special Inductor 400mA

Share to:

91MLA1200503R air-core inductor is a special type for RF applications, wound with 0.05mm wire diameter for 12 turns with an inner diameter of 0.3mm. The inductance is accurately 17nH±20%, with a maximum withstand current of 400mA, perfectly adapting to the 2-20GHz broadband working scenario. The product has excellent temperature resistance, can operate stably in harsh environments from -55℃ to +125℃, and is suitable for tape welding process. Performance can be guaranteed by glue fixing after assembly. The storage condition is 20-25℃, 40%-60% humidity, with a shelf life of 1 year. Designed for RF signal transmission, the coil is perpendicular to the transmission line and short lead design during assembly, which greatly reduces signal loss and is a high-quality electronic component in the RF and microwave field.
