Ideal for

• Calibration of electronic circuits.
• Setting reference voltage or operating point.
• Service modifications and laboratory prototypes.
• Mounting on printed circuit boards in low-power applications.
• Development, measuring, and control circuits requiring fine resistance adjustment.

Package contents

• 1x 3296W trimmer in the selected resistance variant.

Why choose this product

• The multiturn design allows for more precise adjustment than single-turn trimmers.
• The specified power rating of 0.5 W is suitable for low-power adjustment applications.
• The 2.54 mm pin pitch corresponds to the standard grid used on printed circuit boards.
• Variants with different resistance values cover a wide range of common adjustment needs.
• Vertical adjustment is suitable for boards where access to the trimmer is from above.

Installation and operation instructions

• Before mounting, check the selected resistance value and pin wiring in the specific circuit.
• Do not overheat the pins and component body during soldering.
• Perform adjustments using a suitable screwdriver without excessive mechanical force.
• Do not exceed the specified power rating of the component.

Safety warnings

• The component is intended for use in electronic circuits and requires correct wiring according to the device design.
• Incorrect wiring or exceeding the power rating can lead to overheating, component damage, or circuit failure.
• Installation in devices connected to hazardous voltage may only be performed by a person with appropriate electrical qualifications.
• Before handling the populated board, disconnect the power supply and discharge any energy storage elements in the circuit.
