UHV1E122MHD

The UHV1E122MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHV series designed for general-purpose power applications. It combines a high 1200 µF capacitance at 25 V with low impedance and elevated ripple-current capability to support power smoothing and bulk energy storage in compact through-hole designs.

Key value propositions include low impedance at high frequency, high ripple-current handling, wide operating temperature range of −40°C to 105°C, and a long endurance rating of 6000 hours at 105°C, all in a compact φ12.5 × 20 mm can with radial leads.

Key Features

• Capacitance & Voltage — 1200 µF rated capacitance at 25 V, with capacitance tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 41 mΩ to help reduce ripple and voltage drop in high-frequency conditions.
• High Ripple Current — Low-frequency ripple current: 1.485 A (at 120 Hz); high-frequency ripple current: 2.475 A (at 100 kHz), supporting demanding ripple environments.
• Temperature & Endurance — Operating temperature range −40°C to 105°C and rated endurance of 6000 hours at 105°C under DC bias plus rated ripple current.
• Electrical Losses & Leakage — Tangent of loss angle (tan δ) 0.13 (20°C, 120 Hz) and leakage current specified at 300 µA.
• Package & Mounting — Radial lead, can-style package; case dimension φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Power supply smoothing — Low impedance and high ripple-current capability make it suitable for smoothing and bulk decoupling on DC power rails.
• DC–DC converter support — Compact radial package and high-frequency ripple handling help stabilize converter outputs and reduce voltage ripple.
• Industrial and consumer electronics — General-purpose energy storage and filtering in equipment that requires extended endurance at elevated temperatures.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 1.485 A (120 Hz) and 2.475 A (100 kHz) reduce heating and extend service life in ripple-heavy circuits.
• Low high-frequency impedance: 41 mΩ impedance supports better performance in high-frequency applications compared with higher-impedance parts.
• Long endurance at elevated temperature: 6000 hours at 105°C under rated conditions supports reliable operation in demanding thermal environments.
• Compact radial can: φ12.5 × 20 mm package with 5 mm lead spacing offers a space-efficient through-hole solution for legacy and industrial PCB layouts.
• Measured electrical characteristics: tan δ = 0.13 (20°C, 120 Hz) and specified leakage current of 300 µA provide predictable loss and leakage behavior for design margins.
• Regulatory compliance: RoHS compliant material set simplifies regulatory tracking and procurement.
