Resistors balance pulse power capability with physical size

The HS power resistors are manufactured using a high-quality wire-wound design to maximise this high pulse capability. For example, from high ambient temperatures the power dissipates linearly to zero. Ten standard wattages are offered, from 10W-300W. The HS resistors are manufactured in line with the requirements of MIL 18546 and IEC 115 and are RoHS compliant.

The HS power resistors are optimised for linearity, stability and reliability, making them suitable for many different applications including: snubber; braking resistor; inrush limiter; inverter/converter; and balancing resistor designs.

The ARCOL HS power resistors are designed and manufactured for easy assembly. The Ohmic resistance values vary from R005 to 100K depending on wattage size and the tolerances values for low Ω values are typically ≥ R05 ±5% ≤ R047 ±10%. The temperature coefficients are typically < 1K 100ppm standard > 1K 25ppm as standard. Many different electrical terminations are available.
