LMHF RANGE
 LMHF EMI SUPPRESSION FILTER CONNECTORS


FILTER TYPES AVAILABLE

All measurements in this catalogue are quoted in reference to a 50 Ohm system.  The performance of a suppression filter is normally measured in a circuit where both the source and load impedance are 50 Ohms.  50 Ohms is considered to be an industry standard for many practical reasons.  However, should a situation arise where the system is not 50 Ohms we can provide graphs of typical insertion loss on request.
Circuit Styles Electrical Characteristics

C STYLE CAPACITANCE FILTER
Used where source and load impedance are high.  C filters are used where high insertion loss is not required at low frequencies.

LC INDUCTOR AND CAPACITOR
Generally used in systems where source and load impedances are dissimilar. (The inductance is generally placed at the lower impedance side).

Pi CAPACITOR x 2 PLUS 1 INDUCTOR
The Pi filter gives high insertion loss at low frequencies.
