Choke LL2742-100mA
The LL2742 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. LL2742 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: 1.35 kg
Static resistance of each winding: 80 ?
Isolation between windings / between windings and core: 4 kV / 2 kV
Coils in series
Inductance: 42 H
Recommended DC current: 100 mA
Saturating current: 140 mA
Max. ripple voltage at rec. DC current: 640V rms / 100 Hz
Coils in parallel
Inductance: 10 H
Recommended DC current: 200 mA
Saturating current: 280 mA
Max. ripple voltage at rec. DC current: 640V rms / 100 Hz
