UHE1V271MPD

The UHE1V271MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHE series, designed for high-reliability general-purpose applications. It combines a compact φ8 × 20 mm can with low impedance and specified ripple-current performance to support power filtering and decoupling in a range of electronic designs.

Key value propositions include robust ripple-current handling (both low and high frequency), long endurance at elevated temperature, and a wide operating temperature range, making it suitable for systems that require dependable bulk capacitance in a through-hole package.

Key Features

• Capacitance & rated voltage — 270 µF nominal capacitance at a rated voltage of 35 V with a tolerance of −20% to +20%.
• Low impedance — Specified impedance of 270 mΩ supports reduced voltage ripple under load.
• Dielectric loss (tan δ) — tanδ = 0.12 (measured at 20°C, 120 Hz), providing predictable AC loss characteristics for design budgeting.
• Ripple-current capability — Low-frequency ripple current 735 mA (120 Hz) and high-frequency ripple current 1.05 A (10 kHz) for effective smoothing across frequency ranges.
• Leakage current — Specified leakage current of 94.5 µA for power-sensitive circuits.
• Long endurance — Rated for 7000 hours at 105°C, supporting durable operation in elevated-temperature applications.
• Package & mounting — Radial lead can, case size φ8 × 20 mm, lead spacing 3.5 mm (lead spacing tolerance ±0.5 mm), supplied in bulk or bag packing.
• Wide operating temperature — −40°C to +105°C for broad environmental compatibility.
• RoHS compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• General-purpose power filtering and decoupling — Bulk capacitance for smoothing DC rails and reducing ripple in power supplies.
• Industrial and control electronics — Energy storage and ripple management where long life at elevated temperature is required.
• Consumer and communications equipment — Bulk smoothing and transient suppression in through-hole assemblies.

Unique Advantages

• Extended high-temperature endurance: 7000 hours at 105°C provides predictable lifetime for designs exposed to sustained elevated temperatures.
• Improved ripple handling across frequencies: Specified LF and HF ripple currents (735 mA at 120 Hz and 1.05 A at 10 kHz) combined with low impedance help control voltage ripple in a variety of operating conditions.
• Compact through-hole footprint: φ8 × 20 mm radial can with 3.5 mm lead spacing fits space-constrained PCB layouts while remaining serviceable in through-hole assemblies.
• Designable AC losses: tanδ of 0.12 at 120 Hz (20°C) supports accurate thermal and loss calculations in power designs.
• Low leakage current: 94.5 µA leakage current helps minimize standby losses and supports power-sensitive circuits.
• Production-ready compliance and packing: RoHS compliant and available in bulk or bag packing for assembly and volume production requirements.
