UPJ1H271MHD6

The UPJ1H271MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. It is a radial-lead, polarized can-type capacitor rated at 270 µF and 50 V, optimized for low impedance and long endurance.

Designed for general-purpose power filtering and decoupling, the part is particularly well suited for switching power supplies and other electronic equipment that require compact, robust smoothing and ripple-handling in demanding thermal environments.

Key Features

• Capacitance & Rated Voltage — 270 µF nominal capacitance with a rated voltage of 50 V and a tolerance of -20% to +20%.
• Low Loss (tan δ) — Tangent of loss angle (tan δ) specified at 0.10 (measured at 20°C, 120 Hz), supporting stable AC performance.
• High Ripple Current Capability — Low-frequency ripple current 478.8 mA at 120 Hz and high-frequency ripple current 840 mA at 200 kHz for effective smoothing in switching environments.
• Leakage Current — Specified leakage current of 405 µA, supporting predictable DC behavior in power circuits.
• Long Endurance — Rated for 5000 hours of load life at 105°C, delivering durability under elevated operating temperatures.
• Wide Operating Temperature Range — Operates from -55°C to +105°C for use across a broad set of environments.
• Compact Radial Package — φ16 × 15 mm can with 7.5 mm lead spacing (±0.5 mm) in a radial lead format; available in bulk or bag packing.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• Switching Power Supplies — Output and input filtering where low impedance and high ripple-handling at both low and high frequencies are required.
• Power Conversion Modules — Bulk and decoupling capacitance for DC–DC converters and power regulation stages operating up to 50 V.
• General-Purpose Electronic Equipment — Smoothing and energy storage in compact assemblies that need a reliable miniature radial electrolytic solution.

Unique Advantages

• Designed for Low Impedance: Specified low tan δ and series UPJ characteristics support reduced AC losses and improved filtering performance in switching applications.
• Elevated Ripple Handling: Distinct ripple current ratings at both 120 Hz and 200 kHz provide measurable performance across common power-conversion frequencies.
• Extended High-Temperature Life: 5000-hour endurance at 105°C offers predictable longevity in thermally demanding installations.
• Compact Footprint: φ16 × 15 mm radial can with 7.5 mm lead spacing allows space-efficient placement on through-hole boards while maintaining serviceable capacitance.
• Predictable DC Characteristics: Specified leakage current enables designers to budget for standby and quiescent currents.
• RoHS Compliance: Environmental conformance simplifies regulatory planning for commercial and industrial products.
