UPJ1K120MED

The UPJ1K120MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, offering a 12 µF capacitance at an 80 V rating. It is designed as a low-impedance, general-purpose power capacitor suited for switching power supplies and power‑rail filtering in compact assemblies.

Key electrical characteristics include a wide operating temperature range of -55 °C to 105 °C, a rated endurance of 2000 hours at 105 °C, and quantified ripple-current capability for both low and high frequency applications.

Key Features

• Capacitance & Voltage — 12 µF nominal capacitance with a rated voltage of 80 V and tolerance of -20% to +20%.
• Low-impedance UPJ series — Part of Nichicon’s UPJ family characterized for low impedance behavior, making it suitable for switching power supply filtering.
• Temperature & Endurance — Operates from -55 °C to 105 °C with an endurance rating of 2000 hours at 105 °C.
• Ripple current specification — Low-frequency ripple current 24 mA at 120 Hz and high-frequency ripple current 48 mA at 200 kHz, enabling predictable thermal/ripple performance.
• Leakage and loss — Specified leakage current of 28.8 µA and tan δ (DF) of 0.08 measured at 20 °C, 120 Hz, 80 V.
• Compact radial can package — Size φ6.3 × 11 mm (diameter × length), radial lead mounting with 2.5 mm lead spacing (±0.5 mm) for through-hole PCB placement.
• Packaging options — Supplied in bulk/no terminal forming or bag packing to support flexible assembly workflows.
• Part status — Status: End Of Life (useful for procurement and lifecycle planning).

Typical Applications

• Switching power supplies — Low-impedance behavior and quantified ripple handling make this capacitor suitable for output filtering and bulk decoupling in compact switching regulators.
• Power-rail decoupling — Use for general-purpose decoupling on intermediate DC rails where an 80 V rating and compact radial footprint are required.
• Industrial and consumer power modules — Compact size and broad temperature range accommodate small power modules and board-level power conditioning in varied environments.

Unique Advantages

• Verified ripple handling: Published ripple currents at 120 Hz and 200 kHz let designers estimate thermal stress and lifetime under both low- and high-frequency conditions.
• Compact radial form factor: φ6.3 × 11 mm can simplifies placement in space-constrained through-hole designs while maintaining necessary capacitance.
• Wide operating temperature: Rated from -55 °C to 105 °C to support designs exposed to a broad ambient range.
• Measured leakage and dissipation: Specified leakage current (28.8 µA) and tan δ (0.08) provide deterministic behavior for power-budget and loss calculations.
• Flexible supply format: Available in bulk or bag packing to integrate with different assembly and stocking practices.
• Clear lifecycle indicator: End Of Life status helps procurement and design teams plan for alternates or last-time buys.
