FEATURES
◆ ±3ppm per degree Centigrade temperature co-efficient
◆ Full load stability ±50ppm maximum after three years
◆ Tolerance ±0.005%, ±0.01% and ±0.1%
◆ Axial leads
◆ From stock in 111 popular standard values; to order in
any value from 1 ohm to 1.1 Meg
OHMIC VALUES
Econistors are available in 111 standard values from 1Ω to 1MΩ
and in any “non-standard” values from 1Ω to 1.1MΩ. Three
tolerances are available; 0.1%, 0.01% and 0.005% (0.005%
available on values of 100Ω and above only). Type 8E16
includes all values below 700KΩ; values of 700KΩ and above
are type 8E24. The types are identical except dimensionally;
Type 8E16 is 12.7mm long, Type 8E24 is 19.05mm long. Both
are manufactured using all welded construction.
