TEH140 Series

TEH140

The Ohmite TEH140 series is a high-wattage multiple construction TO-247 power resistor. The TEH140 Series is available in Thick Film and Thin Film construction creating lower-value options. The TEH140 Series performs well in high-frequency applications with an inductance of 12.25 nH at a 10mm terminal length. Thermal stability is also a strong point with TCR values down to 50 ppm and a tolerance of 1% available. Ohmite offers thermal solutions for the TEH140 and other popular package sizes.
