About Product
Current Viewing Resistors (CVRs) are rugged high frequency resistors designed to sustain the very high peak power and current inputs generated by capacitor banks, pulse generator systems, and steady state current loads.

Product Functions
- CVR geometry: rectangular or tubular, as determined by the shape of the conductor connecting to the CVR input.
- Choose your output connector: BNC (standard), SMA, TNC, N, etc.
- Determine the resistance value, energy or power the CVR will need to dissipate.
- Consider the CVR response characteristics you require: bandpass and risetime.
- Consider the dimensions, and performance specifications of the CVRs.
Product Application
