The FUJ DB37-4C is a brake resistor in the Brake Systems category, sitting under Motors & Motor Controls. Its job is to absorb the regenerative energy from a decelerating motor, dumping it as heat so the drive doesn't trip on overvoltage. The order code also appears as DB3.7-4C on the component line — that alternate notation is the same part, not a different variant.
