Maretron Termination Resistors are required on a NMEA 2000 network and are placed at each end of a network trunk cable. Like the double-ended cordsets, the termination resistors are waterproof and continue to function even while submerged in the bilge.• Material: Thermoplastic• Rated Voltage: 300 V DC• Internal Resistor: 120 Ohms (1/2 W)• Temperature Rating: -40°C to 80°C (-40°F to 176°F) Termination resistors are used to terminate both ends of the trunk line | Maretron Mini Termination Resistor, Male - Female
