SMT filters bring interference down to
earth
New block filters in a surface mount packaging offer high-performance filtering by grounding all the high-frequency noise-generating components.
Abacus has introduced new block filters in a surface mount packaging, which offer high-performance filtering by grounding all the high-frequency noise-generating components The new Murata BNX022 replaces the leaded BNX002-01 and comes in a lower cost, lower profile SMD package with equivalent performance and a higher temperature rating

Innovative design minimises the risk of false trips due to high inrush currents and line transients.
These block type passives, part of the EMIFIL range, are resin encased EMI suppression filters, which use a feed-through capacitor having excellent high frequency characteristics.
They are designed for applications where the noise frequency is high, or when extreme countermeasures are required.
Examples include DC power lines of systems such as flat-screen TVs, arcade machines, PCs and peripherals.
A single filter block enables noise suppression of both positive and negative lines, and there are no connection routes in the current circuits, ensuring highly reliable performance.
Key performance figures include a high current rating of 10A, low DC resistance of 0.43ohm and high insertion loss characteristics over the wide 1MHz to 1GHz frequency range.
The package has a footprint of just 12 x 9mm and features a low mounting profile of 3mm - some 10mm lower than equivalent through-hole-mounted filters.
Abacus will support the filters with technical support and guidance based on many years of experience operating in the field of noise suppression.
Technical support is backed by design kits, application manuals and a comprehensive set of software tools that simulate virtually any circuit condition.
