UPJ1C221MPD

The UPJ1C221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series. It delivers 220 µF capacitance at a 16 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing, designed for through-hole PCB mounting.

Engineered as a low-impedance, general-purpose device, this part is ideally suited for switching power supplies and other power-filtering roles where stable performance, ripple handling and elevated temperature endurance are required.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 16 V for bulk decoupling and energy storage in low-voltage power rails.
• Low Impedance Characteristics — Part of Nichicon's UPJ low-impedance series with a specified tanδ of 0.16 (measured at 20°C, 120 Hz), supporting efficient AC ripple suppression.
• Ripple Current Capability — Rated low-frequency ripple current 187.6 mA at 120 Hz and high-frequency ripple current 335 mA at 200 kHz, supporting AC stress in switching environments.
• Leakage Current — Specified leakage current of 105.6 µA, enabling predictable standby and bias behavior after voltage application.
• Temperature & Endurance — Operating range −55°C to +105°C with 3000 hours specified load life at +105°C for the φ8 size, supporting extended high-temperature operation.
• Package & Mounting — Radial lead, can-style package (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing and currently in mass production.
• Tolerance & Polarity — Capacitance tolerance −20% to +20%; polarized electrolytic construction for correct polarity installation.
• Regulatory — RoHS compliant.

Typical Applications

• Switching power supplies — Provides low-impedance bulk capacitance and ripple smoothing in DC-DC converters and switching regulators.
• General-purpose power filtering — Suited for smoothing and energy storage in low-voltage power rails across consumer and industrial electronics.
• Through-hole PCB assemblies — Radial lead form and compact φ8 can simplify placement in through-hole power sections and prototype boards.

Unique Advantages

• Low-impedance performance: Tangent of loss angle (tanδ) of 0.16 at 20°C, 120 Hz supports efficient ripple attenuation and stable AC behavior.
• Designed for power applications: Explicitly positioned for switching power supplies and power-filtering roles, with ripple current ratings specified for both low and high frequencies.
• High-temperature endurance: Rated for 3000 hours at +105°C for the φ8 case size, providing predictable lifetime under elevated temperature stress.
• Compact radial can: φ8 × 11.5 mm package with 3.5 mm lead spacing offers a small footprint for dense through-hole layouts.
• Predictable leakage behavior: Specified leakage current (105.6 µA) helps designers budget quiescent currents and bias leakage precisely.
• Availability and compliance: Mass production status and RoHS compliance simplify procurement and regulatory planning.
