KBL410 Single-Phase Diode Bridge Rectifier — 4A, 1000V, KBL Package (3-Pack)

KBL410 Single-Phase Diode Bridge Rectifier — 4A, 1000V (3-Pack)

The KBL410 is a single-phase full-wave bridge rectifier rated at 4A average forward current and 1000V peak inverse voltage (PIV). In KBL package with a central mounting hole for heatsinking, it converts AC mains voltage to pulsating DC for linear power supplies, transformer-based rectifiers, and battery chargers. Supplied as a 3-pack.
