Vishay / Sfernice RCH Power Resistors

Vishay / Sfernice RCH Power Resistors are designed to be mounted onto a heatsink and bear high short-time overloads. These resistors are manufactured in cermet thick film technology and exhibit remarkable characteristics. The RCH power resistors are noninductive and are particularly suitable for high-frequency operation and cut-out circuits. These resistors are compliant with NF-EN45545-2 and offer three types of terminals. The RCH power resistor features easy mounting, reduced size and weight, and a high power rating. These resistors operate at 0.24Ω to 1MΩ wide resistance range, 0.8°C/W high thermal capacity, and -55°C to 125°C operating temperature range.
