1515SQ, 2222SQ, 2929SQ Series Square Air Core Inductors

Coilcraft 1515SQ, 2222SQ, 2929SQ Series square air core inductors have extremely high Q factors and very tight inductance tolerances, making them suitable for narrowband RF amplifier matching and tuning applications. As their name implies, air-core inductors do not use a magnetic core, resulting in high Q and the lowest possible losses for high-frequency applications. High-reliability versions are available for space, military, and other critical applications.
