LL2772: Lundahl Filament Choke

The LL2772 is available in 4 versions. Suitable for low voltage, high current power supplies.

• 12mH, 10A, wired in parallel
• 20mH, 6A, wired in parallel
• 50mH, 5A, wired in series
• 80mH, 3A, wired in series

• Please refer to the datasheet on how to wire the chokes, be it in series or parallel. Please note that Lundahl only labels the chokes with the series value. To clarify a choke labelled (in bold):

  LL2772 50mH (5A) has a value of 12mH (10A) when wired in parallel
  LL2772 80mH (3A) has a value of 20mH (6A) when wired in parallel

(N.B. Adjusting the airgap adjusts the DC current and inductance. This is done at the Lundahl factory.)

There are further 2 versions depending on what C-core material you require.

• Silicon-iron
• Amorphous-iron (AM)

Dimensions - 97mm x 75mm x 57mm
