Replacement coil for 32X part L7

Units on Hand: 42



32X may emit a strange hissing or whining noise when operating.  Certain coils seem more prone to becoming noisy with age.

Usage / installation notes:

  • Coil noise is typically a symptom of a problem in the regulation circuit but sometimes the glue or wrapping holding them together can give out, causing them to emit noise.
  • If your stock 32X coil is not noisy, there is no reason to replace it.
  • We do not recommend pre-emptive coil replacement if no symptoms exist.
  • Original coils have hard-mounting legs but these do not.  After installing & testing, a spot of hot glue or slilcone adhesive around the base is recommended to help secure for transport.

Please see photo regarding soldering locations.  Some original coils have 3 legs.  The 3rd is a stabilizing leg connected to ground and should not be left open.

Anecdotally, if you have a Sharp voltage regulator at IC13 (large letter S, part number starts with 3) you may want to consider replacing it.  The Sharp regulators seem to be more prone to oscillation.
