Choke LL1685-130mA

The LL1685 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. LL1685 can be used in choke input and cap input applications. 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: 0.75 kg
Static resistance of each winding: 65 W
Isolation between windings / between windings and core: 4 kV / 2 kV

Coils in series
Approx. Inductance: 13 H
Recommended DC current: 130 mA
Saturating current: 190 mA
Max. ripple voltage at rec. DC current (Ripple voltage is approx. 0.42 x input voltage): 330V rms / 100 Hz

Coils in parallel
Approx. Inductance: 3 H
Recommended DC current: 260 mA
Saturating current: 380 mA
Max. ripple voltage at rec. DC current (Ripple voltage is approx. 0.42 x input voltage): 165V rms / 100 Hz
