The UPJ1H2R2MDD is a Nichicon UPJ-series aluminum electrolytic capacitor in a compact radial-can package. It delivers 2.2 µF capacitance at a 50 V rating with low impedance characteristics suited for switching power supplies and general-purpose power filtering.

Key attributes include a wide operating temperature range of -55°C to 105°C, low leakage, and defined ripple performance across low and high frequencies. Note: this part is listed as End of Life; request a quote or contact sales to confirm availability or alternatives.

Key Features

• Electrical Performance – 2.2 µF nominal capacitance at 50 V with ±20% tolerance, suitable for decoupling and power-filtering roles.
• Low Loss – Specified tan δ of 0.1 at rated voltage, providing reduced dissipation for power applications.
• Ripple Handling – Low-frequency ripple current 13.5 mA (120 Hz) and high-frequency ripple current 27 mA (200 kHz) for steady operation under AC stress.
• Low Leakage – Leakage current specified at 4 µA, supporting stable bias conditions and low standby currents.
• Thermal and Lifetime – Rated for operation from -55°C to 105°C with a specified lifetime of 2000 hours at 105°C.
• Compact Radial Package – φ5 × 11 mm can with 2 mm lead spacing, radial-lead mounting for through-hole assemblies; supplied Bulk/No Terminal Forming.
• Polarized – Standard polarized aluminum electrolytic construction for application in DC circuits.
• RoHS Compliant – Meets RoHS directive requirements for environmental compliance.

Typical Applications

• Switching Power Supplies – Low-impedance UPJ series construction is expressly suited for switching regulator output and input filtering.
• General-Purpose Power Filtering – Useful for bulk decoupling and smoothing in general electronic circuits.
• High-Frequency Ripple Suppression – Specified high-frequency ripple rating (27 mA at 200 kHz) supports EMI/ripple reduction in compact designs.

Unique Advantages

• Low-Impedance Design: Series-level low impedance characteristics help improve voltage stability in switching applications.
• Measured Ripple Performance: Separate low- and high-frequency ripple current specifications provide clear guidance for thermal and ripple budgeting.
• Compact Footprint: Small φ5 × 11 mm can and 2 mm lead spacing enable use in space-constrained through-hole assemblies.
• Wide Temperature Range: Rated from -55°C to 105°C to support a broad set of environmental conditions.
• Low Standby Current: 4 µA leakage current helps minimize quiescent power draw in standby or low-power modes.
• Regulatory Compliance: RoHS compliance simplifies environmental verification for product designs.
