UPJ1J221MHD

The UPJ1J221MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized capacitor specified at 220 µF and 63 V, designed for applications that require low impedance and stable performance across a wide temperature range.

Targeted for power conversion and general-purpose filtering, this unit delivers quantified ripple handling, low loss, and extended endurance—making it suitable for engineers specifying components for long-life equipment and demanding thermal environments.

Key Features

• Electrical performance: 220 µF capacitance at a rated voltage of 63 V with capacitance tolerance ±20% (120 Hz, 20°C).
• Low loss / low tan δ: tan δ = 0.08 measured at 20°C, 120 Hz, 63 V, supporting efficient energy handling in power circuits.
• Ripple current capability: Low-frequency ripple current 467.6 mA at 120 Hz and high-frequency ripple current 835 mA at 200 kHz for improved ripple management.
• Leakage current: Specified leakage current 415.8 µA, enabling predictable bias behavior after power-up.
• High-temperature endurance: Rated life of 5000 hours at 105°C, aligned with UPJ series endurance specifications for larger case sizes.
• Wide operating temperature: −55°C to +105°C operational range for deployment across varied thermal environments.
• Radial mechanical package: φ12.5 × 20 mm can, radial lead spacing 5.0 mm ±0.5 mm with lead diameter 0.6 mm; available in bulk or bag packing.
• Compliance: RoHS compliant.

Typical Applications

• Switching power supplies: Low-impedance UPJ series design supports ripple suppression and stable filtering in switch-mode power stages.
• General-purpose power filtering: 220 µF / 63 V rating and elevated ripple capability suit decoupling and bulk filtering in a variety of power subsystems.
• Equipment operating across wide temperatures: −55°C to +105°C range and 5000-hour endurance at 105°C make it suitable where thermal robustness is required.

Unique Advantages

• Quantified ripple handling: Specified low- and high-frequency ripple currents (467.6 mA at 120 Hz, 835 mA at 200 kHz) let designers size capacitors to system ripple requirements with confidence.
• Low dissipation factor: tan δ = 0.08 at 63 V reduces AC losses and supports efficient power-stage operation.
• Extended high-temperature life: 5000 hours at 105°C delivers predictable long-term performance for sustained high-temperature use.
• Compact radial can: φ12.5 × 20 mm form factor with 5.0 mm lead spacing enables straightforward through-hole mounting in constrained layouts.
• Clear electrical limits: Measured leakage current and tolerance specifications provide deterministic electrical behavior for margin and reliability calculations.
• Production availability: Listed as mass production, facilitating procurement for volume designs.
