Features
1. Ultra-small size in 1.6x0.8x0.8mm
2. Steep insertion loss characteristics realize
excellent noise suppression and prevent distortion
of signal waveform.
3. By minimizing stray capacitance of inductor,
achieves high performance in noise suppression
in high frequency range.
4. Five different values of cut off frequency are
available, ranging from 100MHz up to 500MHz.
5. No polarity using the same structure on all the
side electrode.
