UHV1E271MPD

The UHV1E271MPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHV series designed for general-purpose power applications. It combines 270 µF capacitance at 25 V with a compact φ8 × 11.5 mm can and radial lead mounting for space-constrained PCB designs.

Engineered for low impedance and high ripple handling, this mass-production part offers measurable performance benefits for power filtering and decoupling across an operating range of −40°C to +105°C, with RoHS compliance and long endurance of 6000 hours at 105°C.

Key Features

• Capacitance & Rated Voltage — 270 µF nominal capacitance, rated for 25 V with ±20% tolerance to support bulk energy storage and decoupling functions.
• Low Impedance — Measured impedance of 181 mΩ helps reduce AC voltage ripple and maintain stable filtering performance at high frequencies.
• High Ripple Current Capacity — 450 mA (120 Hz) low-frequency ripple and 900 mA (100 kHz) high-frequency ripple current ratings support demanding power conversion and switching environments.
• Loss Tangent — tanδ of 0.13 at 20°C and 120 Hz for predictable dissipation characteristics in AC conditions.
• Leakage Current — Specified leakage current of 67.5 µA for controlled standby loss and predictable behavior after voltage application.
• Temperature & Endurance — Operating temperature range −40°C to +105°C with 6000 hours endurance at 105°C for long-term reliability under elevated temperature stress.
• Compact Radial Can Package — φ8 × 11.5 mm size with 3.5 mm lead spacing (±0.5 mm tolerance) and radial lead mounting for through-hole or hybrid assembly; available in bulk/bag packing.
• Polarized Design — Polarized aluminum electrolytic capacitor suitable for DC bias circuits where polarity is defined.
• Regulatory — RoHS compliant and in mass production, supporting commercial procurement and manufacturing continuity.

Typical Applications

• Power supply filtering and smoothing — Bulk capacitance and low impedance reduce output ripple and stabilize DC rails in converters and linear supplies.
• Switching regulator decoupling — High ripple current ratings support switching frequencies and dynamic load conditions common in DC-DC converters.
• Industrial and consumer electronics — Compact radial can and wide operating temperature range make it suitable for general-purpose power circuits in compact assemblies.

Unique Advantages

• High ripple tolerance: 900 mA at 100 kHz and 450 mA at 120 Hz enable robust handling of AC stress from switching and ripple-heavy supplies.
• Predictable AC behavior: Specified tanδ (0.13 at 120 Hz, 20°C) and 181 mΩ impedance give engineers measurable parameters for thermal and stability calculations.
• Long-term endurance: 6000 hours at 105°C provides a defined lifetime metric for designs requiring extended high-temperature operation.
• Space-efficient form factor: φ8 × 11.5 mm can with 3.5 mm lead spacing fits tight PCB layouts while providing useful bulk capacitance.
• Controlled leakage: 67.5 µA leakage current helps limit standby losses and supports predictable bias conditions after voltage is applied.
• RoHS compliance and production readiness: Environmentally compliant and in mass production for reliable sourcing and assembly planning.
