LINE FILTER INDUCTORS
TM0049
Bel offers a series of line inductors designed to assist
in eliminating or reducing noise transmission in AC
or DC circuit applications. For example, these noise
suppression chokes are superior output
inductors when used in a switch mode power supply.
Our inductors are packaged in a compact, rigid vertical
case with "set" terminal pins to simplify mounting on
computer boards in microcomputer applications.
* Excellent Linear Magnetic
Characteristics.
* Operating Temperature Range
0oC to 70oC.
* A Toroid core to maintain
reduced flux leakage.
* Excellent vibration resistance.
