UPA1A122MPD

The UPA1A122MPD is a Nichicon UPA-series radial lead aluminum electrolytic capacitor offering 1200 µF capacitance at a 10 V rating. It is a miniature, low-impedance, polarized can-style capacitor designed for compact power-electronics applications.

Engineered for switching power supplies and general-purpose power filtering, this part combines high ripple-handling capability, wide operating temperature range, and long endurance for reliable performance in demanding ambient conditions.

Key Features

• Capacitance & voltage: 1200 µF nominal capacitance with a 10 V rated voltage and tolerance of −20% to +20%.
• Low impedance: Specified impedance of 88 mΩ, enabling effective smoothing and decoupling in tight power rails.
• High ripple current: Rated ripple current of 1.037 A at 120 Hz (low frequency) and 1.22 A at 10 kHz (high frequency) to support switching supply and converter loads.
• Temperature and endurance: Operating temperature from −55°C to +105°C with an endurance rating of 3000 hours at 105°C.
• Leakage and loss characteristics: Leakage current specified at 360 µA and tan δ (DF) of 0.19 measured at 20°C, 120 Hz and 10 V.
• Compact radial package: φ8 × 20 mm can size, radial lead mounting with 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Regulatory status: RoHS compliant and available in mass production.

Typical Applications

• Switching power supplies: Low impedance and high ripple current capability make it suitable for output smoothing and bulk storage in compact supply designs.
• General-purpose power filtering: Used for bulk decoupling and energy storage in electronic equipment where a compact radial can is required.
• Compact power modules and DC-DC converters: Small φ8 can size and high ripple handling support space-constrained power modules and converter boards.

Unique Advantages

• Compact form factor with high capacitance: 1200 µF in a φ8 × 20 mm can allows designers to save board area without sacrificing capacitance.
• High ripple tolerance across frequencies: Rated ripple currents at both 120 Hz and 10 kHz provide reliable performance for low- and high-frequency switching environments.
• Robust temperature range and endurance: −55°C to +105°C operation and 3000 hours endurance at 105°C give predictable long-term behavior in elevated-temperature applications.
• Low impedance for better transient response: 88 mΩ impedance improves voltage stability under dynamic load conditions.
• Production-ready packaging: Available in bulk or bag packing and listed as mass production to support volume builds.
• RoHS compliant: Conforms to RoHS requirements for lead-free product integration.
