Nidec Components' SM-3/31 series is a 3 mm square, multi-turn SMD, sealed trimmer. The device can be ordered with J-hook terminations in the popular top adjust model, or with gull-wing or J-hook terminations in side adjust models. The SM-31 has 5 adjustment turns, while the SM-3 trimmer has 11 adjustment turns for applications where adjustment accuracy is critical. Both models feature precious metal alloy contacts for reliability and precision setting. Materials used meet the UL94V-0 flammability standard and the SM-3/31 series is RoHS-compliant.
Nidec Components' SM-3/31 3 mm trimmers are ideal in applications where board space is limited. Typical applications for this product include medical test and monitoring equipment, RF amplifiers, portable industrial test equipment, telecommunications products, surveillance systems, and power supplies.
