RESI SOTC0227F1K00KZ

The SOTC planar non-inductive power resistor, also known as the SOT-223 package high-power resistor, adopts the SOT-223 (Small Outline Transistor 223) package — a common package format for high-power transistors, small-to-medium-scale ICs, and power resistors. The SOTC series resistors are rated at 3W and feature a bottom-mounted heat dissipation flange design that increases thermal pathways to balance the thermal characteristics of the circuit, delivering excellent heat dissipation performance. They are typically designed for current sensing, energy absorption and discharge, RC snubbing, high-speed switching, and high-frequency transmitter circuits, and are also widely used in voltage regulation, constant power loads, and low-energy pulse loads. Target application industries include industrial lasers, welding equipment, test equipment, instrumentation, UPS, automotive, switching power supplies, and other end products. The SOTC series high-power resistors offer outstanding long-term stability, low temperature coefficient, high thermal dissipation, low thermal resistance, and low current noise, making them suitable for a broad range of applications. From raw materials to core equipment and core processes, this series achieves full in-house control, ensuring stable quality and on-time delivery.
