Wirewound Series
Vitreous Enamel Power
Select Euro series fixed resistors for applications
requiring wattage ratings from 72 to 1000 watts.
Suitable for rugged applications, Euro-Power resistors are spot welded producing stronger mechanical and electrical connections. The vitreous enamel
coating was specifically developed and provides
protection against moisture and mechanical damage.
Euro-Power resistors are equipped with lug terminals suitable for soldering or sturdy bolt connection.
Mounting brackets not included with resistors.

c h aracteristics
Coating Lead free vitreous enamel. Very large models (700 watts and up) are supplied in Silicone Ceramic. Also
available in low-cost Centohm coating; Consult factory.
Core Tubular ceramic.
Terminals solder coated radial lug with RoHS composition solder
Derating Linearly from 100% @ +25°C to 0% @ +350°C.
Tolerance ±5% 1Ω and over (J); ±10% under 1Ω (K)
Power rating Based on 25°C free air rating.
Overload 10 times rated wattage for 5 seconds.
Temperature coefficient 1 to 20Ω: ±400 ppm/°C; Above 20Ω: ±260 ppm/°C; Ribbon wire: 400ppm/°C
Dielectric withstanding voltage 1000 VAC: 72 to 160 watt rating. 3000 VAC: 280 to 700 watt rating (Measured from terminal to mounting bracket)
To calculate max. amps use the formula √P/R
