Markings on Thick Film Chip Resistors may have an internal lot identification code or the E-24 (5%) or E-96 (1%) marking code. If value identification is required,
please consult your sales person for availability.
Values available in the E-24 Series that are crossover values (same value for 1% and 5%) will typically be marked with a 3-digit E-24 Series marking code.

Anti-Sulfuration Test Data
Test Conditions:
Chip resistors are mounted on the test board with the power “ON” and kept in the atmosphere of 50˚C,
Relative Humidity of 95% and present in the atmosphere is H2S – 3PPM.
10 pieces each of regular chip resistors and anti-sulfuration chip resistors were tested.
Hours >> 1,000 2,000 3,000 4,000 4,500 5,000 5,500 6,000 6,500 7,000 8,000 8,500 9,000

Anti-sulfuration
chip resistors ooooooooooooo
o = No failure. X1 = 1 failure. X2 = 2 failures. X3 = 3 failures.
Test Results:
Regular chip resistors start failing (open) from 4,500 hours and by 8,500 hours, all have failed (opened).
Anti-sulfuration chip resistors have no failures up to 9,000 hours and beyond.
