3329H-1-500 Description

Short technical summary and product information.

The Bourns 3329H-1-500 is a 1/4 inch round, single-turn, cermet trimmer potentiometer designed for industrial applications. It offers a resistance value of 50 Ohms with a standard tolerance of ±10% and a power rating of 0.5W at 85°C.

 

This trimmer features top adjustment and PC pin termination, making it suitable for through-hole mounting. The cermet resistive element provides infinite resolution and a wide operating temperature range of -55°C to +150°C. Environmental testing includes humidity, vibration, and shock resistance, along with a load life of 1,000 hours.

 

The 3329 series is listed on the QPL for style RJ50 per MIL-PRF-22097 and RJR50 per High-Rel MIL-PRF-39035. A RoHS compliant version is available. This model is sealed and designed for reliable performance in demanding environments.

 

Key electrical characteristics include an insulation resistance of 1,000 megohms min. at 500 VDC and dielectric strength of 600 VAC at sea level. The adjustment angle is 240° nominal.
