Description Of The Cement Fixed Wirewound Power Resistor 5W 47K 5%
Ampfort’s wire wound resistors are made by winding the resistance wire around the glass fiber core or ceramic core. For high ohmage value and resistance range 1% the metal oxide film will be used instead of the wire wound. Two types of packaging are available. Type one using non-corrosive. Heat proof, humidity proof, and nonflammable.
Features Of The Cement Fixed Wirewound Power Resistor 5W 47K 5%
* Low noise
* Instance overload capability; long term stability
* Excellent insulation being used in PCB
* Excellent heat dissipation; small linear
* Metal oxide film cutting core can offer high range resistance (1Ω--100KΩ)
* Operating temperature range
Wire Wound:-55°C--+155°C
Metal Oxide:-30°C--+155°C
