Product Positioning and Core Use

The NRSS series is a 2W 5% tolerance anti-pulse non-inductive resistor designed for electronic circuits where pulse performance and low parasitic inductance are important selection factors. It features flameproof painting with resistance to heat and solvents, while its inductance is specified at less than 1 μH.

The product is referenced to IEC 60115-4 and JIS C 5201-4, providing defined electrical and mechanical performance requirements for resistor applications.

Key Specifications

The 2W rated power is listed in the NRSS product specifications, while the ordering information identifies J as 5% resistance tolerance.

Applications

Automotive Electronics

For automotive electronic circuits, the NRSS resistor can be considered where anti-pulse performance and low inductance are relevant to resistor selection. The 2W rated power and 5% tolerance provide defined selection parameters, while the inductance specification of less than 1 μH supports circuit designs where parasitic inductance needs to be considered.

Pulse and Transient Circuit Applications

The NRSS series is suitable for circuit designs where pulse loading is an important consideration. Its specified pulse characteristics are supported by a short-time overload test at 16 times rated wattage for 5 minutes, providing a defined test condition for evaluating short-duration overload performance.

Low-Inductance Circuit Design

For circuits where resistor inductance is an important design parameter, the NRSS series provides an inductance specification of less than 1 μH. This directly supports its positioning as a non-inductive resistor and low inductance resistor for pulse-sensitive circuit designs.

Heat and Solvent Exposure

The resistor uses a flameproof coating specified as resistant to heat and solvents. Its operating temperature range is -55°C to +155°C, providing a defined temperature range for component selection in the applicable circuit environment.
