Typical applications: • Avionic flight controls • Airborne systems • Naval electronics • Military, aerospace, or commercial aircraft The S , 83000 & CSS series are ultra-miniature transformers in an encapsulated package with design layouts as through-hole or surface mount types. They can operate over a wide temperature range of -55°C to +130°C. Our proprietary materials and methods allow extreme temperatures of vapor phase, IR or other reflow procedures without degrading the high reliability of their physical form and electrical performance. • Extreme resistance to impact, shock, and vibration • Manufactured to MIL-PRF-27, Class S, Grade 5 • High reliability for space and mission critical applications • Ultra miniature in size and minimalistic design • Design layouts in through-hole or surface mount types • Available with magnetic shielding and/or electrostatic shielding • Certain parts are QPL approved Contact Pico for part number of available options: • Screening and qualification criteria to flight standard • Capability to thermal shock up to 300 cycles • Extra layers of magnetic shielding • Fully RoHS compliant or with exemption 7(a) • Modifications to mechanical design and electrical characteristics • Custom new design and parameters
