UKW2A101MPD

The UKW2A101MPD is a Nichicon UKW series aluminum electrolytic capacitor in a radial lead can, specified at 100 µF and 100 V. It is designed for audio and AV equipment, leveraging a new electrolyte formulation intended to realize a harmonious balance of sound quality.

Key electrical and mechanical attributes include a 100 µF capacitance with ±20% tolerance, polarized radial-lead construction, a compact φ10 × 20 mm case, and an operating temperature range of −40°C to 85°C with 2000 hours endurance at 85°C.

Key Features

• Capacitance and Voltage — 100 µF nominal capacitance with ±20% tolerance and a rated voltage of 100 V, suitable where high voltage headroom and moderate capacitance are required.
• Audio-focused Electrolyte — Part of the UKW series developed for audio equipment; the new electrolyte is described as contributing to a harmonious balance of sound quality for AV applications.
• Ripple Current Capability — Rated ripple current of 350 mA at 120 Hz (low frequency) and 525 mA at 10 kHz (high frequency), with frequency coefficients for the 100 µF class of 1.00 at 120 Hz and 1.50 at 10 kHz or more.
• Leakage and Endurance — Specified leakage current of 300 µA and endurance of 2000 hours at 85°C (measured after rated-voltage application and recovery to 20°C per endurance test conditions).
• Mechanical Package — Radial lead can with dimensions φ10 × 20 mm and lead spacing 5.0 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for flexible assembly and prototyping.
• Temperature Range and Polarization — Polarized capacitor rated for operation from −40°C to +85°C; intended for circuits that accept polarized electrolytic components.
• Regulatory Compliance — RoHS compliant as part of the UKW product information.

Typical Applications

• Audio and AV Equipment — Suited for audio signal chain and AV system designs where the UKW series’ electrolyte characteristics support balanced sound quality.
• Power Filtering in Audio Systems — Used in power-supply smoothing and decoupling within AV electronics that require a 100 µF, 100 V polarized capacitor.
• Prototyping and Repair — Radial lead form and bulk/bag packaging make the part convenient for bench assembly, module repairs, and small-volume builds.

Unique Advantages

• Audio-Optimized Electrolyte — Specifically developed electrolyte in the UKW series aimed at achieving a harmonious balance of sound quality for AV applications.
• High Voltage Rating — 100 V rated voltage provides margin for higher-voltage rails or designs requiring increased breakdown headroom.
• Compact Radial Can — φ10 × 20 mm footprint with 5 mm lead spacing delivers a small, serviceable package for tight PCB layouts and through-hole assemblies.
• Broad Ripple Handling — Defined ripple current ratings for both low and high frequency (350 mA @120 Hz, 525 mA @10 kHz) and documented frequency coefficients for the 100 µF class.
• Durability in Elevated Temperatures — Endurance specified at 2000 hours at 85°C, enabling predictable performance in sustained elevated-temperature environments.
• Production Availability — Listed as in mass production and supplied in bulk or bag packing for manufacturing flexibility.
