UKT1A101MDD

The UKT1A101MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UKT series designed for audio equipment. It delivers 100 µF capacitance at a 10 V rating in a compact φ5 × 11 mm can with radial leads, offering a wide operating temperature range for demanding environments.

Engineered for applications that require reliable decoupling and filtering in audio designs, this polarized capacitor combines a small footprint with defined ripple and leakage characteristics suitable for compact audio assemblies.

Key Features

• Capacitance & Voltage — 100 µF capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Package & Mounting — Miniature radial can package (φ5 × 11 mm) with 2 mm lead spacing (±0.5 mm) for through-hole, radial-lead mounting.
• Temperature Range — Wide operating range from −55°C to +105°C to support designs exposed to extended temperature extremes.
• Ripple Performance — Low-frequency ripple current of 105 mA at 120 Hz and high-frequency ripple current of 157.5 mA at 10 kHz, enabling effective smoothing in audio circuits.
• Leakage & Dissipation — Leakage current specified at 30 µA and a measured tangent of loss angle (tan δ) of 0.26 measured at 20°C, 120 Hz, 10 V.
• Endurance — Rated life of 1000 hours at 105°C, with endurance specifications evaluated after restoration to 20°C.
• Reliability & Compliance — AEC-Q200 rated and RoHS compliant, meeting reliability and environmental requirements reported in the product data.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.

Typical Applications

• Audio Equipment — Suited for miniature audio assemblies where compact decoupling, filtering and smoothing are required.
• Embedded Audio Modules — Useful in compact amplifier modules and signal-path boards that need a small, polarized electrolytic capacitor with defined ripple capability.
• Consumer Audio Devices — Applicable to small form-factor consumer audio products requiring a wide temperature range and low leakage characteristics.

Unique Advantages

• Compact footprint: φ5 × 11 mm can size provides high capacitance in a small package to save PCB space in constrained audio designs.
• Wide temperature tolerance: −55°C to +105°C operation supports designs exposed to thermal extremes without sacrificing performance.
• Defined ripple and leakage specs: Specified ripple currents (105 mA @120 Hz, 157.5 mA @10 kHz) and 30 µA leakage allow predictable behavior in power and audio filtering applications.
• Durability: 1000-hour endurance at 105°C gives a quantifiable longevity metric for thermal stress conditions.
• Industry reliability rating: AEC-Q200 rating and RoHS compliance indicate adherence to established reliability and environmental standards noted in the product data.
• Flexible supply: Available in bulk or bag packing to support prototyping and production needs.
