UHE1H272MHD

The UHE1H272MHD is a radial-lead aluminum electrolytic capacitor offering 2700 µF capacitance at a 50 V rating in a compact φ18 × 40 mm can. It combines low impedance and long-life endurance for general-purpose power applications that require bulk energy storage and ripple handling.

Designed for use across a wide temperature range (−40 °C to 105 °C) and rated for 10,000 hours at 105 °C, this RoHS-compliant component delivers high ripple-current capability and stable performance in continuous-duty environments.

Key Features

• Capacitance & Voltage: 2700 µF at 50 V provides substantial bulk capacitance for smoothing, energy storage, and decoupling in power circuits.
• Low Impedance: Specified impedance of 38 mΩ to support low-loss charge/discharge behavior and improved transient response.
• High Ripple Current Capacity: Handles 3.04 A (120 Hz) and 3.8 A (10 kHz), enabling effective ripple dissipation across low and high frequency ranges.
• Long Endurance: Life rating of 10,000 hours at 105 °C (for rated voltages 16 to 100 V) for reliable long-term operation under elevated temperature and bias.
• Wide Operating Temperature: −40 °C to 105 °C supports deployment in varied thermal environments.
• Compact Radial Can Package: φ18 × 40 mm radial can with 7.5 mm lead spacing and bulk/bag packing simplifies assembly for through-hole PCB layouts.
• Leakage & Loss Angle: Leakage current specified at 1350 µA and tan δ of 0.12 (measured at 20 °C, 120 Hz) for predictable electrical characteristics.
• Polarized Design & Tolerance: Polar capacitor with capacitance tolerance of −20% to +20% for standard electrolytic design considerations.
• Regulatory Compliance: RoHS compliant for environmental and material requirements.

Typical Applications

• General-Purpose Power Supplies — Bulk smoothing and ripple filtering where 2700 µF and 50 V ratings provide energy buffering and improved regulation.
• Industrial Electronics — Continuous-duty power systems that benefit from the 10,000-hour life at 105 °C and elevated ripple-current capability.
• DC Bus & Energy Storage — Local energy storage and transient suppression on PCB-mounted through-hole designs using a compact radial can.

Unique Advantages

• High Capacitance in a Compact Can: 2700 µF in a φ18 × 40 mm package reduces board area compared with larger cans while providing significant bulk capacitance.
• Robust Ripple Handling: 3.04 A (120 Hz) and 3.8 A (10 kHz) ripple ratings support both low- and high-frequency power conditioning needs.
• Long-Term Reliability: 10,000-hour endurance at 105 °C (for 16–100 V range) helps extend maintenance intervals and improves uptime in thermal-stressed applications.
• Low Loss & Predictable Performance: 38 mΩ impedance and tan δ = 0.12 (20 °C, 120 Hz) deliver low-loss operation and consistent AC behavior.
• Easy Integration: Radial lead form with 7.5 mm lead spacing and bag/bulk packing facilitates through-hole assembly and prototyping workflows.
• Environmental Compliance: RoHS conformity supports deployment in regulated product lines.
