UPJ2E2R2MPD

The UPJ2E2R2MPD is a Nichicon UPJ-series aluminum electrolytic capacitor with a 2.2 µF capacitance and a 250 V rated voltage in a radial-lead can package. It is a low-impedance, polarized electrolytic designed for general-purpose power applications and is noted in the series documentation as well suited for switching power supplies.

Key product attributes include a compact φ10 × 12.5 mm can, a wide operating temperature range of −40°C to 105°C, a rated life of 5000 hours at 105°C, and RoHS compliance. Packaging is offered in bulk or bag formats. Status: End Of Life.

Key Features

• Electrical Rating — 2.2 µF capacitance at 250 V rated voltage with polarization appropriate for DC power circuits.
• Low Loss / Performance — Dissipation factor (tanδ) of 0.2 measured at 20°C, 120 Hz for predictable AC loss behavior in filtering and supply circuits.
• Ripple Current Capability — Low-frequency ripple current: 32 mA (120 Hz); high-frequency ripple current: 51.2 mA (200 kHz), suitable for decoupling in switching environments.
• Leakage Current — Specified leakage current of 95 µA for defined post-charge behavior.
• Reliability / Endurance — Load life rated to 5000 hours at 105°C, with endurance characteristics defined by the UPJ series.
• Mechanical / Package — Radial-lead can, size φ10 × 12.5 mm, lead spacing 5 mm (±0.5 mm), lead diameter per series spec, packaged in bulk or bags.
• Temperature Range — Operating from −40°C to 105°C for a broad set of ambient conditions.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and series qualification indicate suitability for decoupling and smoothing in switching regulators and converters.
• General Power Filtering — Polarized radial-lead form factor and 250 V rating support general-purpose power filtering in industrial and consumer electronics.
• Compact Radial-Lead Designs — Small φ10 × 12.5 mm can and 5 mm lead spacing make it suitable for space-conscious through-hole layouts requiring higher voltage handling.

Unique Advantages

• High Voltage Handling: 250 V rating allows use in higher-voltage DC circuits without upsizing the capacitor.
• Low-Impedance Performance: Series-level emphasis on low impedance aligns the part to switching supply decoupling where stable impedance at frequency matters.
• Defined Endurance: 5000 hours at 105°C provides a measurable life expectancy for thermal-stressed power designs.
• Compact Through-Hole Form Factor: φ10 × 12.5 mm radial can reduces board footprint compared with larger radial electrolytics while maintaining rated voltage.
• Measurable Ripple and Leakage Specs: Specified ripple currents (120 Hz and 200 kHz) and leakage current enable straightforward thermal and reliability budgeting in designs.
• RoHS Compliance: Meets RoHS requirements for use in lead-restricted assemblies.
