Common Mode EMI Choke Series50pH to 20mH, Up to 9.9ARMS Common Mode ChokePRODUCT OVERVIEW Typical applications: • DC-DC Converters • Switching Power Supplies • Communication Interfaces • Aviation Power Systems • Medical Equipment • Lighting Systems Pico's Common Mode EMI Chokes are highly effective in suppressing electromagnetic interference and radio frequency interference, where high-frequency noises are blocked to allow DC and low-frequency AC signals to pass through. These noise suppression devices can be offered in common mode or differential mode operations. They are extremely reliable in the performance of electronic systems where security of data and information are crucial, as well as mechanically durable to the integrity of mission systems. • Extreme resistance to impact, shock, and vibration Contact Pico for part number of available options: • Manufactured to MIL-PRF-27 Grade 5, Class S (Except Screening and qualification criteria to flight standard Fully RoHS compliant or with exemption 7(a) Modifications to mechanical design and electrical characteristics Custom new design and parameters Size 0 which is Class V) • • High reliability for space and mission critical applications • • Ultra miniature in size and minimalistic design • • Design layouts in through-hole, or surface mount • Magnetically shielded (through-hole only) • • Terminal solderability per MIL-STD-202, Method 208
