Typical applications: • DC-DC Converters • Switching Power Supplies • Communication Interfaces • Aviation Power Systems • Medical Equipment • Lighting Systems HCM series is a newer line of Pico capable common mode chokes at highest current capability to the expense of minimal saturation density loss. They are the smallest size for any industry; meeting harsh environmental conditions than the typical commercial and non-sealed designs. These noise suppression devices can be offered in common mode or differential mode operations. They are extremely reliable in the performance of power systems, where space could be a limitation, as well as mechanically durable to any setting. • Extreme resistance to impact, shock, and vibration • Manufactured to MIL-PrF-27 Grade 5, Class S • High reliability for space and mission critical applications • Ultra miniature in size and minimalistic design • Terminal solderability per MIL-STD-202, Method 208 Contact Pico for part number of available options: • 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

Common Mode EMI Choke Note 1: Parts are available with Pb-free dipped terminals that is compliant to RoHS exemption 7 by requesting part number + '-RoHS-7' Note 2: Inductance measured at 0.1VRMS and 10kHz. Note 3: Maximum ambient plus temperature rise is limited 130°C. Note 4: Minimum inductance is 80% of listed value with no maximum value. Note 5: Winding balance at ±1%.

Common Mode EMI Choke PICO SPECIFICATIONS Note 6: Screening and qualification tests are not limited to the options in the chart above. Each standard may also be stringent or exclude certain tests from one another. Please contact Pico for specific application needs and for Pico part number.
