RST Electric presents the Axial Cement Wirewound Resistor – a versatile, high-power through-hole resistor designed for applications demanding reliable performance in a standard axial-lead package. Encased in a flame-retardant ceramic housing with inorganic silica filler, this Axial Cement Resistor delivers excellent heat dissipation, low noise, and a wide operating temperature range. With power ratings from 5W to 100W and resistance values ranging from 0.1Ω to 100kΩ (wirewound/metal film variants), it is ideally suited for power supplies, motor controls, industrial drives, and consumer electronics. Available in tolerances from ±1% to ±10% with a low temperature coefficient (≤ ±250 ppm/°C), this Power Wirewound Resistor meets rigorous performance standards including solderability, dielectric withstand, vibration, and endurance testing.

RST Electric introduces the Non-inductive Metal Plate Resistor – a high-performance, low-inductance power resistor designed for demanding applications requiring minimal phase shift and rapid response. Featuring a metal plate element encapsulated in a flame-retardant ceramic housing, this Non-inductive Resistor delivers excellent pulse handling, low resistance values (from 0.01Ω), and stable performance across a wide temperature range. With power ratings from 2W to 7W (single-element) and combined configurations (2+2, 3+3, 5+5, 7+7), it suits current sensing, snubber circuits, high-frequency inverters, and power amplifier applications. Available in tolerances from ±1% to ±10% with a low temperature coefficient (≤ ±250 ppm/°C), this Metal Plate Power Resistor meets rigorous performance standards including solderability, dielectric withstand, vibration, and endurance testing.

RST Electric's Ceramic Heating Element For Home Fragrance Warmer is specially designed for household fragrance warmers, essential oil diffusers, and car fragrance equipment. We use high-purity ceramic cores with precisely wound resistance wires inside, which can provide a gentle and stable heat ranging from 80℃ to 165℃. This allows for the gentle release of fragrance oils without burning or degradation. The power range is 3W to 20W, and the voltage options include 100-120V AC, 220-240V AC, 12V DC, and 5V USB. The ceramic/ceramic shell is durable, with a resistance tolerance of ±5%, ensuring energy efficiency, safety, and aesthetics, and is suitable for various modern health and lifestyle products.

RST Electric presents Open Air Current Sensing Resistor – a high-precision, low-ohmic resistor engineered for accurate current measurement in space-constrained applications. Featuring a metal alloy element with an open-air vertical construction, this Current Sensing Resistor delivers extremely low resistance (from 5mΩ to 100mΩ), minimal inductance, and excellent thermal dissipation. With power ratings of 1W, 3W, and 5W, and tolerances as tight as ±1%, it is ideal for inverter circuits, power supplies, motor controls, and battery management systems. The radial lead design elevates the element above the PCB, maximizing airflow and keeping heat away from sensitive board components. Available in constantan or nichrome materials with a low temperature coefficient (40 ppm/°C), this Metal Element Resistor ensures stable, repeatable performance across a wide operating range.
