1515SQ Series Image

The 151SQ from Coilcraft are Square Air Core Inductors with inductance values of 47 nH, 68 nH, and 82 nH. They have very high quality factors with tight inductance tolerances, making them suitable for narrowband RF amplifier matching and tuning applications. These inductors utilize air as the magnetic core, resulting in high Q-factor and lowest possible losses at high frequencies. They have a current rating of 5.6 A (RMS) and a DC resistance of less than 8.6 m?. These square inductors can withstand up to three 40-second soldering reflows at 260°C and is cooled to room temperature between every cycle, thereby offering high resistance to soldering heat. They measure 3.56 x 3.73 mm.
