## Description

The Cornell Dubilier 105TTA050M is an aluminum electrolytic capacitor featuring a 1 µF capacitance value and a 50 WVDC (working voltage direct current) rating. Housed in a radial lead package measuring 5 mm x 13 mm, this component is constructed within the TTA series framework, engineered for standard general-purpose applications requiring reliable performance across a broad operating temperature range of -40°C to +85°C. The part maintains a standard capacitance tolerance of ±20% measured at 120 Hz and 20°C, exhibiting a maximum equivalent series resistance (ESR) of 165.786 Ω at the same test frequency, alongside an allowable maximum RMS ripple current rating of 10 mA at +85°C. 

Designed for standard power and signal chain topologies, this 50V aluminum electrolytic capacitor is frequently utilized in filtering, bypass, coupling, and DC blocking circuits within industrial and consumer electronics. The device adheres to a load life rating of 2000 hours at its maximum operating temperature of +85°C with rated working voltage and ripple current applied, during which capacitance change remains bounded within 20% of the initial measured value. Its robust construction and stable impedance characteristics across low-temperature extremes (-40°C impedance ratio of 3 relative to +20°C) ensure dependable operation in diverse electronic assemblies.
