Multi-Turn 1/4" (6.35 mm) Square Wirewound Trimmers

FEATURES

• Precious metal wiper

• 0.25 W to +85 °C

• TCR < 50 ppm/°C

• Solderable leads

APPLICATIONS

• Special configurations available

• Military quality at affordable prices

Wirewound trimmers are particularly useful in those

applications where any combination of high power, low

temperature coefficient of resistance and/or excellent long

term life stability are important design considerations.
