UPJ1K221MHD

The UPJ1K221MHD is a high-reliability, low-impedance aluminum electrolytic capacitor in Nichicon's UPJ series. It is a radial-lead, polarized capacitor specified at 220 µF and 80 V with a compact can package (φ12.5 × 30.5 mm).

Designed for general-purpose use and explicitly suited for switching power supplies, the UPJ1K221MHD combines high ripple-handling capability and extended endurance for designs that require robust power filtering and smoothing across −55 °C to +105 °C.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for DC filtering and energy storage in higher-voltage circuits.
• Low Impedance Performance — Characterized as a low-impedance part in the UPJ series, providing improved ripple suppression for switching power supplies and power-regulation stages.
• Ripple Current Capability — Rated low-frequency ripple current of 333.2 mA at 120 Hz and high-frequency ripple current of 595 mA at 200 kHz to support dynamic load conditions.
• Electrical Losses — Tangent of loss angle (tan δ) of 0.08 measured at 20 °C, 120 Hz, supporting predictable AC behavior in filtering applications.
• Leakage Current — Specified leakage current of 528 µA for predictable quiescent behavior after voltage application.
• High-Temperature Endurance — Rated for 5,000 hours at +105 °C under rated conditions, delivering extended operational life in thermally demanding environments.
• Package and Mounting — Radial lead can with dimensions φ12.5 × 30.5 mm (L: 3.05 × D: 1.25 cm) and 5.0 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant and in mass production, providing supply continuity for production designs.

Typical Applications

• Switching Power Supplies — Low impedance and rated ripple current make this capacitor suitable for output filtering and bulk decoupling in switching regulators.
• General-Purpose Power Filtering — 80 V rating and 220 µF capacitance provide DC smoothing and energy storage in a range of general-purpose electronic designs.
• High-Temperature Electronics — Endurance of 5,000 hours at +105 °C supports use in equipment that operates in elevated ambient temperatures.

Unique Advantages

• Low-impedance construction — Improves ripple suppression and transient response in power-regulation circuits.
• High ripple-handling capability — Distinct low-frequency and high-frequency ripple current ratings permit predictable performance across switching and line frequencies.
• Extended high-temperature life — 5,000-hour endurance at +105 °C reduces maintenance and replacement needs in thermally stressed installations.
• Compact radial can — φ12.5 × 30.5 mm package and standard 5 mm lead spacing simplify board-level placement in through-hole designs.
• Measured dielectric loss — tan δ = 0.08 (20 °C, 120 Hz) gives a quantifiable indicator of AC loss for stability calculations.
• RoHS compliant and production-ready — Mass production status and environmental compliance support scalable manufacturing and regulatory alignment.
