EMI Suppression Filters
(EMC and Noise Suppression)

EMI Suppression Filters
Noise suppression has become an important issue, particularly with regard to electromagnetic interference (EMI) and electromagnetic compatibility (EMC).
Murata provides you with total support, including products and design simulation software solutions based on expertise acquired through extensive on-site experience. This enables us to offer noise suppression solutions for a broad array of applications. We provide you product information on EMI suppression filters, including ferrite beads, filters with integrated capacitors (EMIFIL®), common mode choke coils, and block-type (high damping of large currents) filters.

Noise Suppression Course / Case study


Noise Suppression Basic Course   Basic   Noise Suppression Basic Course
To implement noise suppression in digital devices, it is important to have a good understanding of how noise is generated, how it is transferred, and how it causes problems. This introduction provides basic knowledge related to noise suppression, including the principles of noise generation, various ways that noise is transferred, and the characteristics of noise.
