A detonator assembly includes a capacitor, an initiator, a transformer and an addressable chip. The initiator is electrically connected to the capacitor, the transformer is mechanically and electrically connected to the capacitor and the addressable chip is mechanically and electrically connected to the transformer. The initiator may be bonded or fused to the capacitor, and the transformer may be bonded or fused to the capacitor. The capacitor, initiator, transformer and addressable chip form a unified integrated detonating unit.
