Choke LL1638-10H

The LL1638 is a 2 coils choke for tube amplifier anode supply. The choke is available with different core air-gap, which results in different inductance and DC current capability. 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.

Weight: 1.35 kg
Static resistance of each winding: 18 ?
Isolation between windings / between windings and core: 4 kV / 2 kV

Coils in series

Recommended DC current: 150 mA
Saturating current: 215 mA
Max. ripple voltage at rec. DC current: 300V rms / 100 Hz

Coils in parallel
Inductance: 2,5 H
Recommended DC current: 300 mA
Saturating current: 430 mA
Max. ripple voltage at rec. DC current: 150V rms / 100 Hz
