B-JP-1 (50Ω and 75Ω)
The B-JP-1 is a coaxial surge protective device (SPD) with BNC connectors.
The B-JP-1 is a coaxial surge protective device (SPD) with BNC connectors, available in 50 Ω and 75 Ω versions, designed to protect monitoring cameras and video signals. Compliant with IEC 61643-21 (Category C2/D1) and RoHS, the 50 Ω version covers a frequency range from DC to 1.6 GHz and the 75 Ω version from DC to 400 MHz, both with low insertion loss (0.2 dB or less in the main band) and a VSWR of 1.1 or less. It withstands impulse currents of 5 kA (8/20 µs) and 1 kA (10/350 µs), with a voltage protection level of 1.5 kV or less and a DC sparkover voltage of 350 V ±20%. Its compact design delivers reliable protection without degrading signal quality.
