Product Overview
A 50 ohm rectangular multiturn Trimpot from Bourns: model 3069, pin style P, ordered as 3069P-1-500. A slotted screw at one end of the body drives the wiper along the element, so the setting comes in over several turns instead of a fraction of one.
Key Features
- Resistance: 50 Ω, printed on the body both as 50Ω and as Bourns resistance code 500
- Bourns model 3069, pin style P; ordering number 3069P-1-500
- Three in-line pins along one long edge: 1 and 3 at the element ends, 2 on the wiper
- CW molded at the pin 3 end of the top face
- Multiturn adjustment through a slotted screw at one end of the rectangular body
Applications
- Swapping a worn 50 ohm 3069P off an instrument board with the same part number, pinout and value
- Dialing in a low-value zero, offset or bias adjustment on the bench, where several turns of screw give finer control than a single-turn trimmer
Frequently Asked Questions
What is the 500 printed next to 3069P?
Bourns' resistance code for 50 ohms. The body also prints 50Ω on the line below, so the value reads two ways.
Which pin is the wiper?
Pin 2. Pins 1 and 3 are the ends of the element, and CW is molded at the pin 3 end.
What am I getting, and what am I taking on?
One used Bourns 3069P trimmer, 50 ohms, wiper on pin 2. The leads differ in condition and length, and the part has had a visual inspection only, no function test. Photos are of the actual stock; putting it on the bench before it goes into a circuit is your side of the deal.
The TRIMPOT mark molded on top is Bourns' own trademark, a name so tied to the job that it gets used for trimmers of every make. This one wears the original, so the next move is finding the screwdriver that fits the slot.
