T&M SSDN-0025 high-frequency non-inductive coaxial shunt 0.0025 Ω high-precision resistor 2 watt nut

T&M CVR high-frequency non-inductive resistor, designed for monitoring pulse generator systems, the extremely high peak power and current input produced by steady-state current loads, and transient current monitoring; in recent years, with the rapid development of power semiconductors and wide-bandgap devices, evaluation of device dynamic performance (double-pulse) requires high-precision capture of the current waveforms at the overall turn-on and turn-off instants while minimizing the probe's own insertion loss.  

Key features:

• GHz measurement bandwidth, picosecond-level measurement delay;

• Patented technology, extremely low inductance;

• Monitoring of continuous signals (W) or high-energy pulses (J);

• 0.2% ultrahigh resistance accuracy;

• Maximum power dissipation of 2–3 W per unit;

• Universal BNC-type connector
