Automotives ranging from two wheelers, auto rickshaws, cars and heavy vehicles consist of several electro-mechanical components and sub-assemblies. Active electronic components in automotives range from ABS and ECU automotive powertrains/safety equipment, car audio, car navigation system, and other automotive infotainment devices. Those components and assemblies may emit RF noise or be exposed to external sources of energy - resulting in unanticipated changes in system operation.
In the automotive industry, this noise is classified into two categories – Broadband (due to electrical arcing) and Narrowband (due to active electronics). Vehicle Original Equipment Manufacturers (OEM) address these EMC considerations in the component and system design phase to build immunity characteristics.
System and component testing can be conducted by simulating "external" sources to ensure immunity characteristics. Most component testing methods are based upon CISPR, ISO standards.
High attenuation, compact size. Available also with shock proof terminals.
General purpose, cost effective filters. High performance with shock proof terminals.
Passive and active filters for ignition and power systems
Helps to reduce harmonic distortion and increase automotive component lifetime, limit the flow of electrical current in transient, short circuit currents, attenuate line spikes and surge currents.
