UPS1C221MPD

The UPS1C221MPD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial lead can designed for general‑purpose power filtering and switching power supply applications. It delivers 220 µF capacitance at 16 V in a compact φ8 × 11.5 mm package, combining low impedance and wide operating temperature for demanding designs.

Engineered for sustained performance, the UPS1C221MPD offers a broad temperature range (−55 °C to 105 °C), rated endurance of 2000 hours at 105 °C, and RoHS compliance—making it suitable where compact size, ripple handling and long life are required.

Key Features

• Capacitance & voltage — 220 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20%.
• Low loss / impedance — tanδ 0.16 measured at 20 °C, 120 Hz and an impedance of 280 mΩ for stable filtering performance.
• High ripple capability — Low‑frequency ripple current 205 mA (120 Hz) and high‑frequency ripple current 410 mA (10 kHz) to support switching regulator outputs.
• Leakage current — Specified leakage current of 105.6 µA (after 1 minute at 20 °C), suitable for power supply decoupling and hold‑up applications.
• Temperature & endurance — Operating range −55 °C to 105 °C with rated life of 2000 hours at 105 °C (φD = 8 to 10), supporting long service life in elevated temperatures.
• Compact radial package — φ8 × 11.5 mm can with radial leads, lead spacing 3.5 mm (±0.5 mm), offered in bulk or bag packing for easy through‑hole assembly.
• Compliance — RoHS‑compliant construction.

Typical Applications

• Switching power supplies — Output filtering and decoupling where low impedance and high ripple current capability are required.
• General-purpose power filtering — Bulk and local decoupling in consumer and industrial electronic assemblies.
• DC‑DC converter outputs — Stabilizing regulator outputs in compact, through‑hole designs.

Unique Advantages

• Compact footprint with high capacitance — 220 µF in a φ8 × 11.5 mm can reduces board area without sacrificing energy storage.
• Designed for switching environments — Specified ripple currents at both low and high frequencies address demands of switching regulators and converters.
• Wide temperature tolerance — −55 °C to 105 °C operating range enables use across varied ambient conditions.
• Long endurance at elevated temperature — 2000 hours at 105 °C (for the specified case size) supports reliable service life in thermally stressed designs.
• Through‑hole convenience — Radial lead can and standard 3.5 mm lead spacing simplify prototyping and repairable assemblies.
