Piher 250K Ohm Horizontal Trimpot – Sealed, Linear Taper, 100V Max

You're mid-build, the circuit's half-soldered, and you need a 250K trim value that actually holds. This Piher horizontal trimpot is sealed against dust and workshop grit, so the wiper doesn't drift the moment you set it. Linear taper means every turn gives you a predictable step — no logarithmic surprises. Wiper ships at the 50% position, so your first adjustment is a fine tweak, not a wild guess. Rated to 100V at 0.1W nominal, with a +/-30% tolerance and 10 ohm end resistance. Grab it, screw it in, calibrate, done

• Sealed dust-proof enclosure keeps workshop debris off the track
• Linear taper for even, predictable adjustment across the range
• Wiper pre-set at 50% — fine-tune from the middle out
• Accidental rotor movement protection locks your setting in place
• 100V max rating, 0.1W nominal power, +/-30% tolerance
• Polyester substrate for stable long-term resistance
