Piher 500K Ohm Horizontal Trimpot – Sealed, Linear Taper, 100V Max

Schemed out a 500K trim stage and the local shop's shelf is empty. This Piher horizontal trimpot is sealed against dust, so your calibration doesn't wander after a week on the bench. Linear taper keeps every turn even — no logarithmic jump that throws your bias off. Wiper lands at 50% from the factory, so you're adjusting, not hunting. 100V max, 0.1W nominal, +/-30% tolerance, 10 ohm end resistance. Screw it in, set your value, leave it alone
