Flange resistors are excellent for mounting directly to heat sinks for improved heat dissipation. The devices are available in single, double and four hole flange mounting styles. These devices have standard resistance values of 50 & 100 ohms, however most designs are available
in non-standard values as well. The flange resistors are offered in power ratings ranging from 10 to 1000 watts. Many designs are available in both BeO and Aluminum Nitride (AlN) substrates.
