Tighter tolerance for low-cost chokes

Following improvements in both materials and manufacturing processes, Schaffner EMC has upgraded the specifications of its popular low-cost EV and EH families of "buckle" chokes.

Following improvements in both materials and manufacturing processes, Schaffner EMC has upgraded the specifications of its popular low-cost EV and EH families of "buckle" chokes As a result, the compact PCB-mounting devices are now suitable for a wider range of EMI suppression duties

Both vertical (EV) and horizontal (EH) configurations are available with current ratings up to 5A.

Typical dimensions are 32 x 22 x 35mm for a 5A-rated EV28 vertical device or 29.5 x 30 x 22.5mm for a similarly rated horizontal-mounting EH28 choke.

Thanks to the use of a new core material and an improved glue process, all devices now feature lower saturating resistances and higher temperature specifications.

Rated performance is now specified at +50C, and the full operating temperature range now spans from -25 to +100C.

All devices feature broadband attenuation characteristics to provide a stable frequency response, thereby avoiding unwanted resonant frequencies.

The chokes also have a low leakage flux, and are constructed from UL-rated materials, making them suitable for both IEC950 and medical applications. Request a free brochure from Schaffner ...
