<strong>On</strong>-<strong>Board</strong> <strong>Type</strong> (<strong>DC</strong>) <strong>EMI</strong> <strong>Suppression</strong> <strong>Filters</strong> (<strong>EMI</strong>FILr)<br />
Block <strong>Type</strong> <strong>EMI</strong>FILr BNX Series<br />
SMD <strong>Type</strong><br />
BNX022 series is SMD type high performance and<br />
provides excellent noise suppression on <strong>DC</strong> power<br />
lines.<br />
■ Features<br />
1. Large rated current (10A-15A) and Low <strong>DC</strong> Resistance.<br />
(0.43m ohm - Typ.)<br />
2. High insertion loss characteristic over a wide<br />
frequency range of 1MHz to 1GHz.<br />
3. Mounting area and volume is reduced.<br />
4. Effective for impulse noise such as electrostatic<br />
discharge or spike noise.<br />
