MRF453A Motorola NPN Silicon Power Transistor Stud-Mount 60W 30 MHz 12.5V (NOS)
$66.91Designed for power amplifier applications in industrial, commercial, and amateur radio equipment to 30 MHz.
- Specified 12.5 V, 30 MHz characteristics: Output power = 60 W, Minimum gain = 13 dB, Efficiency = 55%
NOTE: The MRF453A is similar to MRF455A but with larger stud package. The MRF455A was 3/8" Stud and MRF453A is 1/2" Stud. Larger hole in heatsink and more room on circuit board will allow the MRF453A to replace the obsolete MRF455A.
