UKA1E682MHD

The UKA1E682MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UKA series, specified at 6800 µF and 25 V with polarization. It delivers high capacitance in a φ18 × 35.5 mm can package and is designed for audio and high-grade audio equipment applications where wide operating temperature and long endurance are required.

Key value propositions include wide temperature operation (−55°C to 105°C), AEC-Q200 rating, long endurance (2000 hours at 105°C), and robust ripple-current handling for demanding power applications in through-hole designs.

Key Features

• Capacitance & Voltage — 6800 µF rated capacitance at 25 V provides substantial energy storage for power supply and decoupling needs in through-hole assemblies.
• High Ripple Current Capability — 2040 mA at 120 Hz (low frequency) and 2346 mA at 10 kHz (high frequency) to support dynamic load conditions.
• Low Loss (tan δ) — tanδ of 0.28 measured at 20°C and 120 Hz for the specified part, indicating controlled dissipation for audio-focused applications.
• Leakage Current — Specified leakage current of 5100 µA as provided in the product data.
• Wide Temperature Range — Rated for −55°C to +105°C to support operation across harsh environmental conditions.
• Endurance & Reliability — 2000 hours life at 105°C, meeting endurance criteria after high-temperature biased stress.
• Form Factor & Mounting — Radial-lead, polarized can (φ18 × 35.5 mm) with 7.5 mm lead spacing (±0.5 mm tolerance) for easy through-hole assembly.
• Industry Qualification — Rated AEC-Q200, supporting designs that require this qualification.
• Packaging & Availability — Supplied in bulk with no terminal forming and bag packing; product is in mass production.

Typical Applications

• High-grade audio equipment — Suited to audio systems requiring large capacitance and stable performance across temperature for power rails and energy storage.
• Automotive and harsh-environment electronics — AEC-Q200 rating enables use in applications that require industry qualification and elevated reliability.
• Through-hole power modules and assemblies — Radial-lead can package simplifies insertion into PCB layouts for power-supply filtering in assembled systems.

Unique Advantages

• Substantial capacitance in a compact can: 6800 µF in a φ18 × 35.5 mm package reduces the need for multiple smaller capacitors.
• Designed for high thermal stress: 2000 hours endurance at 105°C provides predictable aging behavior in elevated-temperature environments.
• Robust ripple handling: High ripple-current ratings at both 120 Hz and 10 kHz support fluctuating and high-frequency loads common in audio power stages.
• Qualification-driven reliability: AEC-Q200 rating aligns the part with designs that require formal qualification for passive components.
• Through-hole convenience: Radial lead spacing and standard can dimensions enable straightforward integration into legacy and new board designs.
• Production-ready supply: Bulk bag packing and mass-production status support prototype through volume manufacturing workflows.
