Hammond 1537G 30uH 8A High Current Ferrite Core RF Choke

The 1537G is a high current R.F. choke from the 1537 Series, specified at 30 uH with a tight +/-5% tolerance and a maximum DC current of 8 A. The part page describes it as an RF choke, heavy duty hash choke, suited to designers who need a leaded choke with a defined minimum Q.

Other 1537 parts sharing the 8 A rating are the 1537L, which differ in inductance (100 uH). Its nearest inductance neighbours in the series are the 1537F below it (20 uH, 12.5 A) and the 1537H above it (40 uH, 5 A), so the 1537G fills the 30 uH step at 8 A.

Key electrical values for the 1537G: DC resistance of 0.024 ohms and a minimum Q of 5.3, with inductance tested at 1 kHz. The large ferrite core provides an extended saturation point, and the series lists an optimum frequency range of .01-2 MHz.
