These models incorporate 3, 4 or 5
isolated thick-film resistors of equal
value, each connected between two
pins.
These models incorporate 5, 7, 8, 9 or
10 thick-film resistors of equal value,
each connected between a separate
pin.
4308R-104 (shown above) is an 8-pin
configuration and terminates 6 lines.
Pins 1 and 8 are common for ground
and power, respectively. Twelve
thick-film resistors are paired in series
between the common lines (pins 1
and 8).

Add “F” after resistance code for 1 ꢀ tolerance available from 100 ꢁ through 1ꢂ ꢁ, or add “ꢃ”
after resistance code for 0.5 ꢀ tolerance available from 100 ꢁ through 1ꢂ ꢁ.
Part number suffix examples: -103 = 10K ꢁ, 2 ꢀꢄ -103F = 10K ꢁ, 1 ꢀꢄ -103ꢃ = 10K ꢁ, 0.5 ꢀ
