  Flange Resistors
Mounting: Flange
Florida RF Labs flanged resistors are excellent for mounting directly to heat sinks for improved heat dissipation. The devices come in single, double and four hole flange types. The devices have standard resistance values of 50 & 100 ohms. The flanged resistors are available with power ratings ranging form 10 to 800 watts. The products are available in both BeO and Aluminum Nitride (AlN) substrates.
