Single & Multi-Line
Surface Mount Chokes
Steward’s
board mounted ferrite products provide economical EMI filtering of
differential & common mode noise. Some sizes are also available in through-
hole applications in surface mount and through-hole PCB applications. Their
rugged construction provides superior protection against transient events as
well as much higher peak current handling capability than other EMI
suppression devices.
Features:
•
Up to 10A current rating
•
Most economical components for filtering either single line or groups of signals
•
Can be used as multi-turn
device
•Parts
available in broad band, low frequency and high frequency materials
