Type 470 Series
For applications that demand a
durable, miniature trimming
potentiometer, this military style offers
quality at the right price. Cermet
element technology ensures stability
and performance in these 6mm
diameter components. All units are fully
sealed to withstand immersion in
normal board washing solvents.
