Military applications range from input, output, interstage, output isolation, and drivers. Weighing less than 6 grams and operating effectively in blistering military environments that may reach temperatures of 105°C, the 4218 series features a frequency response of ± 2 dB,, 300 Hz to 100 KHz.
With rated power from 12 to 65 mW at 300 Hz, the maximum distortion ranges from only 5 to 10%. The PRI impedance range measures from 300 to 200 K Ohms while the SEC impedance ranges from 32 to 10 K Ohms and handles up to 7 mA of DC offset.
Designed for endurance, the 4218 series has a life expectancy of more than 10,000 hours. Resilient n high-humidity applications, the series operates effectively in up to 98% relative humidity. The series is also vibration, shock and flame tolerant.
Miniature by design, the transformer series has an above-board height if only 0.600 inches maximum while the pins measure only 0.110 inches long minimum.
