Bourns Trimpot Trim Potentiometers are a variety of surface mount and through-hole trim pots that comply with standardized dimensions, maximum soldering temperature/maximum time limits, and package specification requirements (including RoHS, WEE, and EIA). The housing construction and molding materials used in these potentiometers are compatible with popular manufacturing processes. These hermetically sealed models feature improved sealing technology to withstand high soldering temperatures and thermal shock during normal board flushing. For today's ultra-small resistive elements and sliding contacts, Bourns has developed new techniques to minimize noise and contact resistance variation.
