NTC Thermistors (Disc Type)
Disc Type NTC Thermistors
Type:
ERTD
The “Type ERTD” are disc type negative temperature
coefficient thermistors. Resistances are available
from 8 Ω to 150 kΩ and B Values are from 3000 K to
5000 K.
The thermistors are designed for temperature detection
and temperature compensation, featuring excellent
electrical and thermal stability.
