HVR Pentagon Heavy Duty Tape Wound
Resistors are essentially an extension to the Vitreous
Enamelled Range.
Continuous Power Ratings available
from 250 Watts to 1000 Watts.
The resistor winding is completely
protected by several coats of vitreous enamel, which have
been fired to produce a high reliability resistor, capable
of withstanding adverse conditions.
Typical Applications for HVR Pentagon
Heavy Duty Tape Wound Resistors include Dynamic Braking, or
where a pulse rated resistor is required.
Mainly used for Dynamic
Braking or where a pulse rated resistor is required.
For low
Ohmic Values, resistors
are edge-wound with corrugated tape, as shown in the
illustration.
On this type of resistor, the
power rating can be approximately 25% greater than that
of the equivalent wire-wound resistor, due to the
increased heat dissipation provided by the corrugated
tape.
Tape-wound resistors can also be
provided with adjustable tapping clip (Suffix ADJ).
