UPS1C220MDD

The UPS1C220MDD is a miniature aluminum electrolytic capacitor in a radial-lead can designed for switching power supplies and general-purpose power-filtering applications. It offers a compact φ5 × 11 mm footprint with a 2 mm lead spacing, making it suitable for space-constrained through-hole designs that require reliable capacitance and stable performance across a wide temperature range.

Built for extended operation at elevated temperatures, this part delivers 22 µF capacitance at 16 V with specified ripple handling, low leakage, and a rated endurance under high-temperature stress—attributes that support stable power decoupling and smoothing in compact power systems.

Key Features

• Capacitance and Voltage — 22 µF rated capacitance at 16 V with capacitance tolerance −20% to +20%.
• Miniature Radial Package — Compact φ5 × 11 mm can with radial leads and 2 mm lead spacing (±0.5 mm), optimized for tight PCB layouts and through-hole assembly.
• Wide Temperature Range — Specified to operate from −55°C to +105°C for use in demanding thermal environments.
• High-Temperature Endurance — Rated life of 2000 hours at 105°C, supporting sustained performance under elevated-temperature bias and ripple.
• Ripple Current Handling — Low-frequency ripple current of 27.2 mA at 120 Hz and high-frequency ripple current of 160 mA at 10 kHz, enabling effective smoothing across frequencies.
• Low Loss and Leakage — Tangent of loss angle (tan δ) of 0.16 (measured at 20°C, 120 Hz) and leakage current of 10.56 µA, supporting stable filtering and low standby current draw.
• Compliance — RoHS compliant, meeting directive requirements for restricted substances.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly workflows.

Typical Applications

• Switching Power Supplies — Provides compact output and input filtering in switching regulators where space and thermal endurance are constrained.
• General-Purpose Power Filtering — Suitable for decoupling and smoothing tasks in a range of consumer and industrial electronic assemblies.
• Space-Constrained Designs — Small φ5 × 11 mm can and short lead spacing make it suitable for densely populated PCBs that require through-hole components.

Unique Advantages

• Compact footprint with through-hole robustness: φ5 × 11 mm radial can and 2 mm lead spacing allow use in compact boards while maintaining reliable mechanical mounting.
• Designed for high-temperature operation: Rated for −55°C to +105°C and endurance of 2000 hours at 105°C, providing predictable behavior in hot operating conditions.
• Measurable low-loss performance: tan δ of 0.16 (20°C, 120 Hz) offers quantifiable dissipation characteristics useful for thermal and stability calculations.
• Low leakage current: Specified leakage of 10.56 µA supports low-standby-current designs and predictable bias performance.
• Frequency-aware ripple handling: Specified ripple currents at 120 Hz (27.2 mA) and 10 kHz (160 mA) help ensure adequate filtering across power-conversion frequency ranges.
• RoHS compliant and packaged for production: Environmentally compliant and offered in practical bulk/bag packing options for assembly.
