Product Positioning and Core Applications
The NRSS series is a small anti-pulse non-inductive resistor designed for electronic circuits requiring low inductance and pulse-handling characteristics. It features flameproof painting with resistance to heat and solvents, while combining a compact body size with a 2W rated power.
This configuration uses a 2W rated power and ±2% resistance tolerance. With inductance below 1 μH, the NRSS resistor is suitable for circuit designs where low parasitic inductance is an important component-selection requirement.

For the 2W version, the specified resistance range is 0.22Ω to 200kΩ, with a maximum overload voltage of 350V and a maximum working voltage of 600V. The rated continuous working voltage is determined by the lower value between rated power × resistance value and the listed maximum working voltage.
Applications
Pulse Protection Circuits
The NRSS anti-pulse resistor can be used in electronic circuits where the resistor position is exposed to pulse loads and pulse-handling characteristics are required.
Low-Inductance Electronic Circuits
With inductance below 1 μH, the NRSS provides a defined low-inductance characteristic for electronic circuit designs where parasitic inductance needs to be considered during resistor selection.
Flameproof Electronic Circuits
The resistor uses flameproof painting and is resistant to heat and solvents. This makes it suitable for electronic circuits where flameproof construction and resistance to specified environmental conditions are required.
Compact Power Resistor Applications
The NRSS combines a small body size with a 2W rated power, making it suitable for electronic circuit positions where available installation space and resistor power requirements need to be considered together.
