3/8" Square Multi-Turn Cermet Trimmers
FEATURES
• Industrial Grade
• 0.5 Watt at 70 °C
The T93 is a small size trimmer - 3/8" x 3/8" x 3/16" - answering
PC board mounting requirements.
Five versions are available which differ by the position of the
control screw in relation to the PC board plane and by the spacing
• Tests according to CECC 41 000
• Contact resistance variation < 1 % typical
• Lead (Pb)-free and RoHS compliant
of the terminals.
Excellent operational stability is provided by the use of a cermet
element.
