UPA1V272MHD

The UPA1V272MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPA series engineered for switching power supplies and general-purpose power designs. It delivers low impedance, high ripple-current capability and a compact radial-can package for dense power-filtering applications.

Key attributes include a 2.7 mF rated capacitance at 35 V, a wide operating temperature range down to –55°C and up to 105°C, and RoHS compliance for regulated assemblies.

Key Features

• Capacitance & Rated Voltage — 2.7 mF capacitance rated for 35 V operation, suitable for bulk filtering and energy storage in power rails.
• Low Impedance — Specified impedance of 35 mΩ for improved ripple performance and lower voltage drop under AC conditions.
• High Ripple Current — Rated ripple current of 2.389 A at 120 Hz and 2.81 A at 10 kHz to support high-frequency switching applications.
• Compact Radial Can Package — Radial, can-style construction with lead spacing of 7.5 mm and overall size L: 3.05 × D: 1.6 cm, enabling space-efficient PCB layouts.
• Wide Temperature & Lifetime — Operating range –55°C to 105°C with specified endurance up to 5,000 hours at 105°C.
• Polarized, Through-Hole Mounting — Polarized capacitor with radial leads for straightforward through-hole assembly and mechanical robustness.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
• Tolerance — Capacitance tolerance specified at –20% to +20% for predictable design margins.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple current capability reduce output ripple and thermal stress.
• DC–DC Converters — Energy storage and smoothing in compact power modules requiring a high capacitance-to-size ratio.
• Power Management Modules — Local decoupling and transient buffering in general-purpose power electronics.

Unique Advantages

• Low-Impedance Performance: 35 mΩ impedance helps minimize AC voltage drop and supports stable regulation in switching circuits.
• High Ripple Endurance: Rated ripple currents at both 120 Hz and 10 kHz address low- and high-frequency switching environments to reduce heating and extend service life.
• Compact Footprint: Radial can dimensions (L: 3.05 × D: 1.6 cm) with 7.5 mm lead spacing enable tighter component placement on PCBs.
• High-Temperature Reliability: Specified 5,000 hours at 105°C provides predictable lifetime performance in elevated-temperature assemblies.
• Regulatory Compliance: RoHS conformity supports deployment in assemblies requiring restricted-substance compliance.
