UPJ1A221MED

The UPJ1A221MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized electrolytic designed for general-purpose use with emphasis on low impedance performance suited to switching power supplies.

Key characteristics include a 220 µF capacitance at 10 V, a compact φ6.3 × 15 mm can, wide operating temperature range (−55°C to 105°C) and specified ripple/leakage figures to support PCB power-filtering and decoupling designs.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance, rated at 10 V.
• Low Loss — Tangent of loss angle (tanδ) of 0.19 measured at 20°C, 120 Hz for predictable AC performance.
• Ripple Current Capability — Specified low-frequency ripple current of 151.2 mA (120 Hz) and high-frequency ripple current of 270 mA (200 kHz).
• Low Leakage — Leakage current specified at 66 µA for predictable standby and bias behavior.
• Temperature & Endurance — Operating temperature range from −55°C to 105°C with an endurance rating of 2000 hours at 105°C.
• Package & Mounting — Radial lead can (φ6.3 × 15 mm) with 2.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant as part of the UPJ series.

Typical Applications

• Switching Power Supplies — Output filtering and decoupling in switching regulators where low impedance and stable capacitance are required.
• Through-Hole PCB Power Decoupling — Radial lead form and 2.5 mm lead spacing simplify placement in through-hole assemblies and power modules.
• General Purpose Power Filtering — Bulk and smoothing capacitor for low-voltage power rails across a wide temperature range.

Unique Advantages

• Compact radial can — φ6.3 × 15 mm package minimizes board space for through-hole implementations.
• Series-level low-impedance design — UPJ series emphasis on low impedance aids effective filtering in switching applications when combined with the part's 220 µF value.
• Measured AC performance — Specified tanδ (0.19) provides a clear reference for loss calculations at 20°C, 120 Hz.
• Defined ripple handling — Both low- and high-frequency ripple current ratings (151.2 mA and 270 mA) support thermal and lifetime planning in power circuits.
• Predictable leakage and tolerance — 66 µA leakage current and ±20% capacitance tolerance simplify biasing and energy-hold calculations.
• Wide temperature endurance — −55°C to 105°C operating range with a 2000-hour endurance rating at 105°C for reliable performance in varied environments.
