Power

Vitreous Enamel Power

Select Euro series fixed resistors for applications

requiring wattage ratings from 72 to 1000 watts.

Suitable for rugged applications, Euro-Power resis-

tors are spot welded producing stronger mechani-

cal 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 termi-

nals suitable for soldering or sturdy bolt connection.

Mounting brackets not included with resistors.

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 mount-

ing bracket)

To calculate max. amps
