UKA1E102MPD

The UKA1E102MPD from Nichicon is a radial-leaded aluminum electrolytic capacitor in the UKA series designed for high-grade audio equipment and applications that require wide temperature operation. It provides 1000 µF nominal capacitance at a 25 V rating with a compact φ10 × 20 mm can and standard radial lead spacing.

Engineered for sustained performance, this part combines a broad operating temperature range and long endurance with specified ripple-current capability and controlled loss (tan δ), making it suitable for demanding power and audio environments where reliability and stability matter.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, rated for 25 V operation.
• Loss Angle (tan δ) — tanδ = 0.18 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for predictable performance in audio circuits.
• Ripple Current Capability — Low-frequency ripple current of 680 mA (120 Hz) and high-frequency ripple current of 782 mA (10 kHz), specified to support filtering and supply stabilization at relevant audio frequencies.
• Leakage Current — Specified leakage current of 750 µA, enabling predictable bias behavior after voltage application.
• Temperature & Endurance — Rated for operation from −55°C to +105°C with an endurance specification of 2000 hours at 105°C.
• Package & Mounting — Radial lead, can-style package with dimensions φ10 × 20 mm and 5 mm lead spacing (±0.5 mm), packed in bulk or bag formats.
• Qualification — UKA series includes AEC-Q200 rating as a documented rating for this family.
• Production Status — Part is in mass production, suitable for immediate design integration and volume sourcing.

Typical Applications

• High-grade audio equipment — Specified in the UKA series for high-grade audio use, offering the temperature range and loss characteristics valued in audio circuitry.
• Audio power supply filtering — Ripple-current ratings at 120 Hz and 10 kHz support smoothing and decoupling duties on audio power rails.
• Long-life electronic systems — 2000-hour endurance at 105°C and wide operating temperature make this capacitor appropriate where sustained performance across temperature is required.

Unique Advantages

• High capacitance in a compact can — 1000 µF in a φ10 × 20 mm package helps reduce board space while preserving bulk energy storage.
• Designed for audio performance — Series positioning and measured tanδ provide controlled loss characteristics important for audio signal integrity and power conditioning.
• Broad temperature tolerance — −55°C to +105°C operation extends usability across harsh and variable environments.
• Defined ripple-handling — Separate low- and high-frequency ripple current specifications give clear guidance for thermal and performance planning in supply designs.
• Long endurance — 2000 hours at 105°C endurance rating supports longer field life in thermally demanding applications.
• Production-ready — Mass production status and standard radial lead format simplify procurement and assembly for volume designs.
