UPJ2A2R2MDD

The UPJ2A2R2MDD is a Nichicon UPJ series radial-lead aluminum electrolytic capacitor offering 2.2 µF capacitance at a 100 V rating in a compact φ5 × 11 mm can. Designed for general-purpose electronics and power conversion tasks, it combines a small footprint with specifications aimed at low-loss filtering and decoupling.

As part of the UPJ family noted for low impedance characteristics, this radial capacitor is suited to applications that require stable performance across a wide temperature range from −55°C to 105°C.

Key Features

• Capacitance & Voltage: 2.2 µF nominal capacitance rated at 100 V for medium-voltage filtering and decoupling.
• Low dissipation factor: tanδ = 0.08 measured at 20°C, 120 Hz and rated voltage (100 V), minimizing dielectric loss in AC conditions.
• Ripple current ratings: Low-frequency ripple current 10.5 mA at 120 Hz and high-frequency ripple current 21 mA at 1 kHz, useful for power-supply decoupling analysis.
• Leakage current: Rated leakage current of 6.6 µA, helping to limit DC loss in bias applications.
• Operating temperature and endurance: Specified operating range −55°C to 105°C with a rated endurance of 2000 hours at 105°C.
• Package & mounting: Radial lead can (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm tolerance), supplied bulk or in bag packing for through-hole assembly.
• Polarized design: Polar capacitor intended for use where correct polarity is observed.
• RoHS compliant: Meets RoHS requirements as noted in the product environmental data.

Typical Applications

• Switching power supplies: Series-level design intent cites suitability for switching supplies; use for output filtering and decoupling where a compact, radial aluminum capacitor is required.
• General-purpose power filtering: 100 V rating and specified ripple currents make this part suitable for general DC bus filtering and noise suppression tasks.
• Embedded and control electronics: Use for local decoupling and energy storage in power-regulated modules within industrial or consumer devices.

Unique Advantages

• Compact, through-hole form factor: φ5 × 11 mm radial can provides a small footprint for designs that require robust through-hole components.
• 100 V voltage capability: Enables use in medium-voltage rails without upsizing capacitor footprint significantly.
• Low loss behavior: tanδ = 0.08 at specified conditions reduces dielectric heating and improves AC performance margins.
• Clear ripple current data: Separate low- and high-frequency ripple current ratings (10.5 mA at 120 Hz, 21 mA at 1 kHz) support frequency-aware thermal and lifetime calculations.
• Wide temperature range: −55°C to 105°C operation supports deployment across varied environmental conditions.
• RoHS compliance: Facilitates use in products requiring RoHS-conforming components.
