UCH Aluminum Electrolytic Capacitors Nichicon UCH Aluminum Electrolytic Capacitors are chip-type devices that offer high reliability and low-temperature ESR specification (6Ω ESR at -40°C/400kHz). These surface-mount capacitors feature a temperature range of -40°C to +125°C and a rated voltage range of 35V. They have a rated capacitance range of 47µF to 100µF with ±20% capacitance tolerance at 120Hz, 20°C. Nichicon UCH Aluminum Electrolytic Capacitors are RoHS compliant (2011/65/EU) and suitable for use in automotive harsh environments such as engine control units and drive systems control units.
