TBL0550-1B 5uH 50A Line Impedance Stabilization Network LISN

The TBL0550-1B is an affordable 5µH LISN designed for conducted emission measurements / line termination in the frequency range of 100 kHz to 400 MHz. It complies with CISPR-25 (EN 55025), numerous automotive manufacturer standards, MIL-STD-461F, DO-160, AECTP-500 and ISO 7637-2.

LISNs are inserted into the supply lines of the EUT (Equipment Under Test). Conducted noise which is present at the supply terminals of the EUT can be measured at the BNC connectors using a spectrum analyzer or a measurement receiver. The source (supply) terminal and the EUT terminal are decoupled by a 5µH inductor.

Two TBL0550-1B in combination with the Tekbox LISN Mate enable separate measurement of common mode and differential mode noise.
