The UPJ1V121MPD6 is an aluminum electrolytic capacitor in a radial-lead can, specified at 120 µF and 35 V with ±20% tolerance. It is a low-impedance device designed for switching power supplies and other general-purpose power-electronics applications that require compact bulk capacitance and reliable high-temperature performance.

Key electrical and mechanical attributes include a -55 °C to +105 °C operating range, radial lead mounting with 5 mm lead spacing, and a compact L × D size of 1.25 cm × 1.0 cm. The part is RoHS compliant and produced by Nichicon.

Key Features

• Capacitance & Voltage: 120 µF nominal capacitance at a rated voltage of 35 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Temperature Range & Endurance: Operates from -55 °C to +105 °C; series specification shows withstanding 5000 hours of load life at +105 °C (3000 hours for specified smaller case sizes).
• Low Impedance Design: Engineered for low impedance to support switching power supply demands and to reduce ripple and loss in power circuits.
• Ripple Current Ratings: Specified ripple current of 198.8 mA at 120 Hz and 375 mA at 200 kHz, enabling effective AC performance in power filtering applications.
• Package & Mounting: Radial lead, can-style package with 5 mm lead spacing and physical dimensions of 1.25 cm length × 1.0 cm diameter for compact PCB layouts.
• Leakage & Dielectric Loss: Leakage current is limited to 0.03CV (µA) after 1 minute at 20 °C; tangent of loss angle (tan δ) for 35 V rating is specified at 0.12 (max).
• Low-Temperature Stability: Impedance ratio Z(-55 °C)/Z(+20 °C) is specified as 3 for the 35 V rating, supporting performance across a wide temperature span.
• Compliance: RoHS compliant.
