UHD1E101MED

The UHD1E101MED is a Nichicon UHD series aluminum electrolytic capacitor in a compact radial-lead can. It delivers 100 µF capacitance at a 25 V rating with a small φ6.3 × 11 mm case and 2.5 mm lead spacing, aimed at general-purpose power filtering and decoupling in space-constrained designs.

Part of the UHD “High Ripple Low Impedance” family, this unit provides lower impedance at high frequency, measurable low dissipation (tan δ = 0.14 at 20°C, 120 Hz), and RoHS compliance. Status: End Of Life.

Key Features

• Electrolytic, Radial-Lead Package – Compact radial can with dimensions φ6.3 × 11 mm and lead spacing 2.5 mm (±0.5 mm) for through-hole mounting.
• Capacitance & Voltage – 100 µF rated capacitance with tolerance −20% to +20% at 120 Hz, 20°C; rated voltage 25 V.
• Low Dissipation Factor – tan δ = 0.14 measured at 20°C and 120 Hz, supporting lower loss in AC/ripple environments.
• High Ripple Current Capability – Handles 283.5 mA at 120 Hz (low frequency) and 405 mA at 100 kHz (high frequency).
• Low Leakage Current – Leakage current specified at 25 µA.
• Temperature & Endurance – Operating range −40°C to +105°C with a rated lifetime/endurance of 2000 hours.
• Packaging & Compliance – Available in bulk (no terminal forming) or bag packing; RoHS compliant.

Typical Applications

• Power Filtering for Compact Electronics – Smoothing and bulk decoupling in compact power supplies where a small radial can is required.
• Decoupling and Energy Reservoir – Local energy storage and decoupling on DC power rails for general-purpose electronic circuits.
• High-Frequency Ripple Management – Mitigating switching and high-frequency ripple in power conversion stages thanks to lower impedance at higher frequencies and specified ripple ratings.

Unique Advantages

• Small Footprint – φ6.3 × 11 mm can provides capacitance in a tight board area for through-hole assemblies.
• Measured Low Loss – tan δ = 0.14 at 120 Hz helps reduce heating and improve efficiency where AC ripple is present.
• Validated Ripple Performance – Explicit ripple current ratings at both 120 Hz (283.5 mA) and 100 kHz (405 mA) support mixed-frequency environments.
• Wide Operating Temperature – −40°C to +105°C operation accommodates a broad range of ambient conditions.
• Low Standby Leakage – 25 µA leakage current for designs sensitive to standby loss.
• Regulatory Compliance – RoHS compliant to meet restricted substance requirements.
