LIT-153A Transient Limiter
Protect Your Instruments from Damage
The Com-Power LIT-153A is engineered to protect EMI receivers and spectrum analyzers during conducted emissions testing (150 kHz – 30 MHz) — absorbing start-up transients and switching spikes generated by the Equipment Under Test (EUT).
With 10 dB in-band attenuation and a 50 Ω N-type interface, the LIT-153A delivers stable, repeatable measurements while minimising uncertainty and simplifying your test setup.
Key Features
Built for Precision EMC Testing
Frequency Range: 150 kHz – 30 MHz
Covers the full conducted emissions frequency range per CISPR and FCC standards — purpose-built for LISN-based disturbance voltage testing.
10 dB In-band Attenuation
Replaces the conventional external 10 dB pad, simplifying test setups and improving day-to-day repeatability without compromising accuracy.
Protects Instrument Input from Transient Voltage Spikes
Drop-in between the LISN and instrument to absorb start-up transients and switching spikes from the EUT — preventing damage and costly downtime, especially in production or frequent test cycles.
Band-Pass Filter to Attenuate Out-of-band Signals
Acts as a band-pass filter to suppress out-of-band interference before it reaches the receiver front end, reducing overload and intermodulation distortion.
Excellent Input/Output VSWR < 1:1.2
Maintains a stable 50 Ω path with N-type connectors, minimising reflections and keeping measurement uncertainty low for confident, repeatable results.
Ideal for Pre-compliance and Compliance Chambers
Suited for troubleshooting noisy power converters and SMPS harmonics on pre-compliance benches and full compliance test environments alike.
Three-Year Warranty
Backed by Com-Power's standard three-year warranty for long-term reliability across production lines and test facilities.
