RST Electric presents Bare Alloy Current Sense Resistor – a high-precision, surface-mount shunt resistor engineered for ultra-low resistance current sensing in demanding power electronics. Featuring an electron beam welded alloy element with pure copper electrodes, this SMD Current Sense Resistor delivers exceptionally low resistance values (from 0.1mΩ to 5mΩ), ultra-low parasitic inductance (0.5nH to 5nH), and minimal thermoelectric EMF (<1µV/°C). Available in 3W, 5W, and 7W power ratings with industry-standard footprints (2512, 3920, 5930, 2726), it is ideal for automotive battery management systems (BMS), high-frequency switching converters, and motor control applications. Tight tolerances down to ±0.5% and low TCR (as low as ±100 ppm/°C) ensure accurate current measurement across a wide temperature range.

RST Electric introduces the Metal Clad Resistor – a low profile, high-performance wirewound resistor engineered for demanding braking and inverter/converter applications. Featuring a flexible design with exceptional pulse overload capability (10 × rated power for 5 seconds), this Metal Clad Resistor delivers reliable energy dissipation in compact installations. With power ratings from 150W to 600W (up to 1200W when heatsink mounted) and resistance ranges from 2.2Ω to 1.1kΩ, it is ideally suited for dynamic braking circuits, motor drives, and power conversion systems. Standard 600V cables simplify integration, while the low profile design enables installation in space-constrained equipment. Available in ±5% tolerance with low TCR (≤ ±150 ppm/°C), this Wirewound Metal Clad Resistor ensures stable performance under repeated pulse conditions.

RST Electric presents the Vertical Ceramic Wirewound Resistor – a space-saving power resistor designed for high-density PCB layouts and chassis mounting. Featuring a rectangular ceramic housing with radial leads, this Vertical Ceramic Resistor stands upright, minimizing board footprint while delivering excellent heat dissipation and mechanical stability. With power ratings from 1W to 20W and resistance values ranging from 0.1Ω to 100kΩ (wirewound/metal film variants), it suits applications including switch-mode power supplies, motor drives, home appliances, and industrial controls. Available in standard vertical (SQM) and special wide-body (WS/WB) configurations, this Radial Lead Power Resistor meets rigorous quality standards including solderability, dielectric withstand, temperature cycling, and endurance testing. 

RST Electric presents 12V Blower Motor Resistor – a dedicated speed control resistor designed for automotive HVAC (heating, ventilation, and air conditioning) systems. Engineered specifically for 12V vehicle electrical systems, this Blower Motor Resistor delivers reliable fan speed regulation with a built-in 240°C thermal fuse for over-temperature protection. With a power rating of 50W and resistance of 0.15Ω (±10%), it is optimized for low-speed fan operation in passenger cars, commercial vehicles, and off-highway equipment. The unit comes pre-wired with 1.5–2.5mm² leads (150–300mm length) for direct plug-and-play installation, simplifying replacement and assembly. Housed in a flame-retardant, weather-resistant package, it withstands harsh under-dash environments, including temperature extremes, vibration, and humidity.
