UHV1V271MPD

The UHV1V271MPD is an aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications. It delivers 270 µF at 35 V in a compact φ8 × 15 mm case with low impedance across a wide frequency range and elevated ripple-current capability.

Engineered for applications that require high ripple handling and reliable operation at elevated temperatures, this RoHS-compliant part offers a 6000-hour endurance at 105°C and is available in bulk or bag packing for production use.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 143 mΩ supports improved performance at higher frequencies; datasheet series notes lower impedance in the high-frequency range.
• High Ripple Current — Rated ripple currents of 665 mA at 120 Hz and 1.33 A at 100 kHz allow robust handling of AC ripple from switching supplies and converters.
• Loss Characteristics — tan δ (DF) of 0.11 measured at 20°C, 120 Hz, supporting stable dissipation behavior for power applications.
• Reliability & Endurance — 6000 hours life rating at 105°C with specified limits for capacitance change, tan δ increase, and leakage current stability after endurance testing.
• Mechanical & Mounting — Radial-lead, polarized can with φ8 mm diameter and 15 mm length, lead spacing 3.5 mm (±0.5 mm) for through-hole assemblies.
• Leakage Current — Specified leakage current of 94.5 µA (after rated voltage application), consistent with the product’s endurance and performance targets.
• Environmental — RoHS compliant; mass-production status for reliable supply continuity.

Typical Applications

• Switching Power Supplies — Output smoothing and bulk decoupling where high ripple current and low impedance at switching frequencies are required.
• DC-DC Converters — Bulk capacitance for converter outputs and intermediate rails benefiting from the part’s high-frequency performance and ripple capability.
• General-Purpose Electronic Equipment — Power filtering and energy storage in industrial and consumer electronics needing durable operation to 105°C.

Unique Advantages

• Compact, high-capacitance package: 270 µF in a φ8 × 15 mm can conserves board space while providing substantial bulk capacitance.
• High ripple handling: 665 mA (120 Hz) and 1.33 A (100 kHz) ripple ratings reduce the need for parallel components in high-ripple circuits.
• Low-frequency and high-frequency performance: Low impedance (143 mΩ) and a tan δ of 0.11 at 120 Hz support stable filtering across common power frequencies.
• Long endurance at elevated temperature: 6000-hour rating at 105°C offers predictable lifetime behavior for designs exposed to sustained thermal stress.
• Through-hole robustness: Radial-lead format with defined lead spacing (3.5 mm ±0.5 mm) simplifies assembly and mechanical retention in conventional PCBs.
• Regulatory compliance: RoHS compliance supports use in markets with restricted substances requirements.
