  • Enclosed, 4-hole mount chokes (some models also available epoxy potted in a black powder paint - drawn steel housing). Potted models mount with 1/4" - 20 hardware (included).
  • Tolerance of 15% on both inductance and resistance.
  • Inductances measured at rated DC current.
  • Minimum 8" long leads.
  • Units will exhibit less inductance at slightly higher currents or more at lower currents.
  • Perfect for high voltage power supply filtering, case matches power transformers and tube audio output transformers.
  • Units are vacuum impregnated with polyurethane varnish for quiet and long life operation.
  • For more sizes and voltages (open - bracket mount type) - see our 153-159 Series.
  • Operating temperature range os -40°C to +65°C.

Hammond Manufacturing Customisation Services
Product Customisation Options:
What makes KGA Enclosures Ltd different from most other larger distributors is that we can offer full customisation services on all enclosures and accessories. All customisation work is undertaken by the relevant supplier, (some smaller production runs are done by utilizing an outside contractor) at their own manufacturing facilities. These services include milling or punching holes and slots into the enclosure or end plates for cables, connectors, switches, etc. Printing and silk-screening services all for the addition of text, logos, and graphics onto both the enclosure and end plates, to allow the end user to easily identify the product, and to allow the final product to look more elegant. Contact us today to see how we can assist you.
Modified Electronic Enclosures:
Almost every enclosure will need some kind of modification to be useful. In house, modifications can be tedious, over-complicated, and a distraction from your core business. A third party shop can add time and expense. Let us help you by delivering quality products made to your exact specifications.
