NRL Epoxy-Sealed Radial Lead NTC Thermistors

Eaton Electronics NRL Epoxy-Sealed Radial Lead NTC Thermistors feature up to 100kΩ resistance rating, ≤15s thermal time constant, and -40°C to +125°C temperature range. The NRL thermistors provide faster thermal response, UL 3656 XLPE insulation lead wire, and offer a non-linear change in resistance vs. temperature. Eaton Electronics NRL NTC Thermistors are ideal for use in medical devices, commercial appliances, industrial process control, and uninterruptible power supplies (UPS).
