Notes:

1. Standard form factor is U-Bracket. For enclosed unit with end fan, add suffix "E"; For enclosed unit with top fan, add suffix "T"; For unit with "current share"

option, add suffix "D".

2. 30 CFM forced air is required to load the U-Bracket version up to 500W. Without forced air, U-Bracket unit can operate up to 360W @ +40°C ambient max.

3. R&N are measured at 20 MHz bandwidth with a 10µF electrolytic capacitor and with a 0.1µF ceramic capacitor in parallel.
