LL2751: Lundahl Choke

The LL2751 is a small size two-coil choke for tube/valve filament current filtering. The coil is wound using our standard high internal isolation technique with isolation foil between each copper layer. The core is an audio C-core of our own production.

The LL2751 is available in 2 versions.

• 0.045H, 1.2A, wired in parallel
• 0.18H, 600mA, 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):

  LL2751 0.18H (600mA) has a value of 0.045H (1.2A) when wired in parallel

  Silicon-iron (STANDARD) core material

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

Dimensions: 54mm x 54mm x 44mm
