The AHL series includes design elements and components providing additional differential mode rejection in low frequency. For use with switched mode power supplies to reduce noise from power supply back into the mains. Filter also provides good attenuation of incoming interference. The AHL is available in the same case sizes as the AH series and contains the same 1A to 50A current rating range.
Electromagnetic interference (EMI) filters are very important elements of nearly all electrical/electroni
EMI filters work by subduing undesirable radio frequency (RF) energy in two very elementary ways: they either form a low impedance path for RF currents to return to the local source of energy, and/or they provide a high-impedance path to prevent RF currents from flowing on a cable, printed circuit board (PCB) trace or some other type of noisy wire, signal trace or circuit element.
Regulations across the globe specify how much RF energy products can emit via radiated and conducted emissions standards, and in some regions, how much RF energy they must tolerate without upset, damage or malfunction via radiated and conducted immunity (commercial) or susceptibility (military) standards.
Ohmite offers multiple EMI filter series to accommodate each unique filter application. Ohmite filters bear the most relevant safety certifications including UL and CSA.
