UPS1A220MDD

The UPS1A220MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPS series. It provides a polarized 22 µF capacitance at 10 V in a compact φ5 × 11 mm can, designed for general-purpose use and for switching power supply applications where low impedance and small footprint are important.

Key attributes include a wide operating temperature range of −55°C to 105°C, a rated endurance of 2000 hours at 105°C, RoHS compliance, and a documented product status of End Of Life.

Key Features

• Electrical Performance — 22 µF nominal capacitance at 10 V with tolerance −20% to +20% and polarization for DC power circuits.
• Low Loss / Low Impedance — tanδ (DF) = 0.20 measured at 20°C, 120 Hz, 10 V, supporting efficient energy handling in power paths.
• Ripple Current Capability — Rated low-frequency ripple current of 27.2 mA at 120 Hz and high-frequency ripple current of 160 mA at 10 kHz for decoupling and filtering across a range of switching frequencies.
• Leakage Current — Leakage current specified at 6.6 µA, suitable for applications where low standby loss is beneficial.
• Temperature and Endurance — Operating range −55°C to 105°C with endurance rated at 2000 hours at 105°C under rated voltage and ripple conditions.
• Compact Mechanical Package — Radial-lead can with dimensions φ5 × 11 mm and 2.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for manual or automated assembly processes.
• Regulatory — RoHS compliant.
• Product Status — End Of Life; useful to know for lifecycle planning and BOM updates.

Typical Applications

• Switching Power Supplies — Provides local bulk and decoupling capacitance in compact power stages where low impedance and small size are required.
• General-Purpose Power Filtering — Suitable for bulk filtering and smoothing in a variety of electronic modules that require a polarized electrolytic capacitor.
• Compact Electronic Modules — Miniature φ5 × 11 mm can makes this capacitor appropriate for space-constrained boards and compact power modules.

Unique Advantages

• Small footprint for space-limited designs: φ5 × 11 mm radial can and 2.0 mm lead spacing minimize board area while delivering 22 µF capacitance.
• Wide temperature capability: Rated from −55°C to 105°C to support demanding thermal environments and extended operating ranges.
• Measured low dissipation: tanδ = 0.20 at 120 Hz (20°C, 10 V) helps reduce loss and heat generation in power circuits.
• Frequency-aware ripple ratings: Separate ripple current ratings for 120 Hz (27.2 mA) and 10 kHz (160 mA) allow clearer selection for both low- and high-frequency filtering tasks.
• Defined endurance: 2000 hours at 105°C provides a clear reliability baseline for thermal and lifecycle planning.
• RoHS compliant: Meets common environmental requirements for contemporary electronics manufacturing.
