UPW1C220MDD

The UPW1C220MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, offering a compact, low-impedance solution for power-conversion circuits. With a 22 µF capacitance at 16 V, polarization, and a miniature φ5 × 11 mm form factor (1.1 × 0.5 cm), it is targeted at switching power supply designs and automotive electronic applications.

Engineered for reliability across a wide temperature range, the capacitor is rated for operation from −55°C to 105°C, carries an AEC-Q200 rating, and is specified for 2000 hours of endurance at 105°C.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20%.
• Low-loss performance — tanδ (DF) of 0.16 measured at 20°C, 120 Hz for stable loss characteristics in power applications.
• Ripple current capability — Low-frequency ripple current of 54 mA at 120 Hz and high-frequency ripple current of 180 mA at 10 kHz, suitable for decoupling and filtering in switching supplies.
• Low leakage — Leakage current specified at 10.56 µA for controlled standby and bias behavior.
• Thermal and endurance rating — Operating temperature −55°C to 105°C and endurance of 2000 hours at 105°C under rated conditions.
• Compact radial package — Radial-lead can with a footprint of approximately 1.1 × 0.5 cm and 2.0 mm lead spacing (±0.5 mm), packed in bulk or bags (no terminal forming).
• AEC-Q200 qualification — Rated to AEC-Q200 standards for use in automotive electronics and other demanding environments.
• Series design intent — Part of the UPW series: miniature-sized, low impedance, and high reliability for switching power supplies.

Typical Applications

• Switching power supplies — Designed to meet the low-impedance and ripple-current demands of switching regulators and converters.
• Automotive electronics — AEC-Q200 rating and wide temperature range make it suitable for automotive electronic modules.
• Compact power modules — Small φ5 × 11 mm package for space-constrained power and control circuits where reliable decoupling is required.

Unique Advantages

• Miniature footprint: Small 1.1 × 0.5 cm package reduces PCB real estate while providing necessary capacitance for power-stage designs.
• Low-impedance behavior: Series design focus on low impedance supports improved transient response and stable operation in switching supplies.
• Measured ripple performance: Specified ripple current values at both low (120 Hz) and high (10 kHz) frequencies help designers assess thermal and filtering margins.
• Automotive-grade qualification: AEC-Q200 rating supports deployment in automotive-grade electronics and other high-reliability applications.
• Wide temperature and endurance: −55°C to 105°C operating range and 2000-hour endurance at 105°C provide predictable lifetime performance under elevated temperature stress.
• Controlled leakage and loss: Low leakage current and defined tanδ at 120 Hz enable predictable bias and power-loss calculations.
