Audio Transformers are transformers that are used over the audio frequency range. Audio Transformers are used in a variety of applications. They can provide galvanic isolation, signal gain/loss, match impedances between two interfaces, can be used as a reference and to provide feedback signal. Pico Electronics’ Audio Transformers are manufactured to MIL-PRF-27 Grade 5 Class S. These ultra-miniature transformers are made for durability while maintaining their electrical characteristics. All catalog transformers are manufactured to meet Mil-Std-202, method 107, thermal shock from -55°C to +130°C. All units can be manufactured with a 300 thermal cycle guarantee. Standard as well as custom designs are available. Pico Electronics, Inc. is an approved QPL source.
