Electromagnetic Pulse (EMP) Effect: energy passing through an I/O or aperture/opening and disrupts or destroys integrated circuits.
High Altitude Electromagnetic (HEMP) Effect: near-instantaneous energy created by a nuclear detonation.
IEMI: intentional malicious generation of electromagnetic energy introducing noise or signals into electric and electronic systems, disrupting, confusing, or damaging these systems for terrorist or criminal purposes.
High Power Electromagnetics (HPEM): general category of transients in electromagnetic environments where peak electric and magnetic fields are very high. These include lightning strikes, electrostatic discharge, arcing events, electromagnetic fields created by a radar system, EMP burst, HEMP burst, IEMI, high power microwave (HPM).
Spectrum Control’s EMP/HEMP filters are designed to protect sensitive electronics equipment during hazardous transient conditions, such as electromagnetic pulses.
Electromagnetic pulse protection filters are employed to absorb a potentially destructive overshoot voltage. Under normal operating conditions, the suppressor circuit exhibits high state impedance that appears transparent to the circuits they protect. If a voltage exceeding the switching voltage is applied to the circuit, the suppressor circuit switches to a very low impedance, effectively shorting out the high voltage. The suppressor circuit will remain in the low impedance state until the current flowing through the suppressor is interrupted or drops to a safe level. Once this occurs, the suppressor resets and returns to a high state impedance.
These high voltage EMP/HEMP Filters will also help meet the requirements of MIL-STD-188-125.
Spectrum Control has over five decades of custom power filter design and testing experience supporting military requirements. We offer low NRE, quick turn design to production, and the ability to offer tailor-made solutions. Our coaxial filter technology, ceramic capacitor capabilities, and magnetic solutions allow us to design and manufacture custom, rugged, high-reliability filters with shorter lead times than competitors.
We have a fully equipped EMC testing laboratory for customer compliance with specific system requirements. This offers a flexible resource to assist in product development by identifying and correcting EMI susceptibility and emission problems. Transient testing (military, lightning, ESD) is also provided.
