The UM-5 is a through-hole quartz crystal designed for compact communication equipment, operating in fundamental mode from 10.000 to 30.000 MHz or third overtone from 25.000 to 90.000 MHz, with a maximum drive level of 500 μW, shunt capacitance of 7 pF, and an AT-cut crystal. It supports load capacitance values specified by the customer, operates across temperatures from -40°C to +90°C, and is RoHS compliant. Equivalent series resistance is up to 60 Ω for frequencies between 30 and 90 MHz in third overtone mode.
Despite the rise in popularity of surface mount technology (SMT) in passive components, through hole packaging has remained an industry staple for eight decades for a reason. The simplicity and efficacy of this technology, along with its ability to be incorporated into a vast array of designs, make it an excellent choice for many different applications.
Crystals with through hole packing are ideal for larger components that will undergo a significant amount of mechanical stress, high voltage, and/or high power. This is because through hole soldering results in a stronger bond between the passive components and the circuit board. Example applications include transformers, connectors, semiconductors and electrolytic capacitors.
Other advantages to using through hole-mounted components include the compact design to decrease the component’s footprint on the circuit board, exceptional shock and vibration resistance, low frequencies and options for industrial temperature ranges and excellent aging and component longevity and durability.
