The PLTT series features a low tolerance of ±0.02% with an absolute TCR of ±5ppm/ºC. These chip resistors are designed to operate over a wide temperature range of -55ºC to +215ºC. The PLTT series is available in four different case sizes with power ratings from 0.25 Watts to 1 Watt and are highly stable with a 0.5% change in resistance (ΔR) when tested for 2000 hours at +215ºC at 25% rated power. The PLTT resistance range is 250 Ohm to 3 MOhm.
