Transient LimiterLIT-153A

Features

• Frequency range: 150 kHz - 30 MHz
• 10 dB Attenuation (in-band)
• Prevent Damage to Instrument Input from Transient Voltage Spikes
• Act as a Band-Pass Filter to Attenuate Out-of-band Signals
• Excellent Input/Output VSWR < 1:1.2
• Three-Year Warranty

• Protects EMI receivers/spectrum analyzers during LISN-based conducted-emissions tests (150 kHz–30 MHz).
• Drop-in between the LISN and the instrument to absorb start-up transients and switching spikes from the EUT.
• Replaces the external 10 dB pad, simplifying setups and improving day-to-day repeatability.
• Reduces overload and intermodulation by filtering out-of-band energy before it reaches the receiver front end.
• Ideal for pre-compliance benches and compliance chambers when troubleshooting noisy power converters and SMPS harmonics.
• Maintains a stable 50 Ω path with N-type connectors to keep measurement uncertainty low.
• Helps prevent damage and downtime, especially in production or frequent test cycles.
