UPJ1H221MHD6

The UPJ1H221MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, specified at 220 µF and 50 V. It is engineered for general-purpose power applications with a low-impedance profile suited for switching power supplies and power-rail smoothing.

With a compact φ12.5 × 15 mm can, 5 mm lead spacing and a long endurance rating at elevated temperature, this part targets designs requiring reliable bulk capacitance, effective ripple handling and straightforward through-hole assembly.

Key Features

• Capacitance & Rated Voltage — 220 µF nominal capacitance at a 50 V rating, tolerance ±20% (measured at 120 Hz, 20°C).
• Low Impedance Design — UPJ series characteristic explicitly optimized for low impedance, making it suitable for switching power supply use.
• Dissipation Factor (tan δ) — tanδ 0.10 (max) at 50 V, measured at 20°C, 120 Hz, supporting efficient AC ripple handling.
• Ripple Current Capability — 375.2 mA at 120 Hz (low frequency) and 670 mA at 200 kHz (high frequency), enabling both LF and HF ripple accommodation.
• Leakage Current — Specified leakage current 330 µA. The series datasheet defines leakage current limits as ≤ 0.03CV (µA) after one minute at 20°C.
• Endurance & Temperature Range — Rated for 5000 hours at 105°C and operating from −55°C to +105°C, delivering long-term stability under elevated temperature stress.
• Package & Mounting — Radial lead, can-style package (φ12.5 × 15 mm), lead spacing 5.0 mm (±0.5 mm), ideal for through-hole PCB layouts.
• Availability & Compliance — Supplied in bulk (no terminal forming) or bag packing; part is in mass production and is RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and ripple performance are required.
• Power Rail Decoupling — Local energy storage and decoupling on 50 V power rails in industrial and electronic equipment.
• General Purpose Power Electronics — Filtering and smoothing in general-purpose designs that require a 220 µF, 50 V polarized capacitor.

Unique Advantages

• Compact High-Voltage Bulk Capacitance: 220 µF at 50 V in a φ12.5 × 15 mm can provides substantial energy storage in a small footprint.
• Designed for Switching Supplies: UPJ series low-impedance characteristic supports stable performance in switching regulator environments.
• Dual-Frequency Ripple Handling: Specified ripple currents at 120 Hz and 200 kHz allow designers to address both mains-frequency and high-frequency switching ripple.
• Long Endurance at Elevated Temperature: 5000 hours at 105°C supports reliable operation in demanding thermal environments.
• Through-Hole Ease of Assembly: Radial-lead format with 5 mm spacing simplifies PCB placement and soldering for hand or wave solder processes.
• Regulatory and Production Readiness: RoHS compliance and mass-production status facilitate easy integration into production BOMs and supply chains.
