UPA1V271MPD

The UPA1V271MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPA series, designed for high-reliability power applications. It delivers 270 µF at 35 V in a compact φ8 × 15 mm can, offering low impedance and high ripple-current handling for switching power supplies and general-purpose power filtering.

Key Features

• Capacitance & Rated Voltage — 270 µF nominal capacitance with a rated voltage of 35 V and tolerance of -20% to +20%.
• Low Loss — Tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz (rated 35 V), for stable AC performance.
• Low Impedance — Impedance specified at 124 mΩ, supporting effective decoupling and transient suppression.
• High Ripple Current Capability — Low-frequency ripple current of 559 mA (120 Hz) and high-frequency ripple current of 860 mA (10 kHz) for demanding power rails.
• Reliability & Endurance — Rated for 3000 hours at 105°C, suitable for long-term operation in elevated-temperature environments.
• Wide Temperature Range — Operates from -55°C to 105°C to accommodate a broad set of thermal conditions.
• Compact Radial Package — φ8 × 15 mm can with radial leads, 3.5 mm lead spacing (±0.5 mm), and bulk/bag packing options for through-hole assembly.
• Polarized, RoHS Compliant — Polarized aluminum electrolytic design with RoHS compliance for regulatory conformity.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and high ripple capability improve voltage stability.
• DC‑DC Converter Output Filtering — Compact decoupling on converter outputs to support transient loads and reduce output ripple.
• General-Purpose Power Filtering — Through-hole applications in industrial and consumer equipment requiring durable electrolytic filtering.

Unique Advantages

• High ripple-current headroom: 860 mA at 10 kHz (and 559 mA at 120 Hz) enables handling of both low- and high-frequency ripple components.
• Compact footprint: φ8 × 15 mm can provides a small board area for designers constrained by space without sacrificing capacitance.
• Low impedance: 124 mΩ impedance helps minimize voltage drop and improves transient response on power rails.
• Robust temperature and lifetime ratings: -55°C to 105°C operating range plus 3000 hours endurance at 105°C supports reliable long-term operation in thermally demanding environments.
• Easy through-hole integration: Radial-lead format with standard 3.5 mm lead spacing (±0.5 mm) simplifies PCB mounting and assembly.
• Regulatory compliance: RoHS-compliant materials support use in modern regulatory environments.
