LL2742: Lundahl Choke

The LL2742 is available in 6 versions.

• 4H, 500mA, wired in parallel
• 6H, 350mA, wired in parallel
• 10H, 200mA, wired in parallel
• 17H, 250mA, wired in series - 1 pieces in stock, silicon core
• 24H, 175mA, wired in series
• 42H, 100mA, 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):

LL2742 17H (250mA) has a value of 4H (200mA) when wired in parallel
LL2742 24H (175mA) has a value of 6H (350mA) when wired in parallel
LL2742 42H (100mA) has a value of 10H (500mA) 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 - 95mm x 75mm x 50mm
