UKA1A101MDD

The UKA1A101MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series, optimized for audio and related high-grade electronics. It delivers 100 µF capacitance at a 10 V rating in a compact φ5×11 mm can, designed for applications requiring wide temperature operation and reliable ripple handling.

Its specification set—100 µF ±20%, low leakage, defined tanδ, ripple-current ratings at low and high frequency, and 2,000 hours endurance at 105°C—targets designers who need stable decoupling and filtering in small, temperature-challenging assemblies.

Key Features

• Capacitance and Voltage — 100 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 10 V operation.
• Low Loss — tanδ (DF) = 0.26 specified at 20°C, 120 Hz, 10 V for predictable AC performance in audio circuits.
• Leakage Control — leakage current specified at 30 µA (consistent with 0.03CV after 1 minute at 20°C), supporting low-noise and low-bias applications.
• Ripple-Current Capability — rated low-frequency ripple current of 105 mA at 120 Hz and high-frequency ripple current of 157.5 mA at 10 kHz for effective smoothing under varying signal conditions.
• Wide Temperature Range and Endurance — operating from −55°C to +105°C with endurance of 2,000 hours at 105°C, enabling reliable operation in demanding thermal environments.
• Compact Radial Package — φ5×11 mm can with 2 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies; available in bulk or bag packing.
• AEC-Q200 Rating — conforming to AEC-Q200 qualification for enhanced reliability requirements where specified.

Typical Applications

• Audio Equipment — Suited for high-grade audio circuitry in the UKA series, serving decoupling, coupling, and power smoothing needs in audio front-ends and amplifiers.
• Compact Power Supply Filtering — Small can size and defined ripple performance make it useful for local supply decoupling in space-constrained boards.
• Temperature-Challenged Electronics — Rated operation to 105°C and 2,000-hour endurance supports use in equipment exposed to elevated ambient temperatures.

Unique Advantages

• Stable AC Performance: Specified tanδ at 10 V, 120 Hz provides predictable loss behavior for audio and precision analog stages.
• Measurable Leakage Limits: Leakage current defined at 30 µA (0.03CV), enabling designers to budget bias and noise margins accurately.
• Frequency-aware Ripple Ratings: Distinct ripple-current figures for low (120 Hz) and high (10 kHz) frequencies support mixed-signal and switching environments.
• High-Temperature Endurance: 2,000 hours at 105°C gives a clear endurance baseline for reliability planning in harsh conditions.
• Compact Through-Hole Form Factor: φ5×11 mm radial can with 2 mm lead spacing delivers a small footprint for legacy and robust mechanical mounting.
• AEC-Q200 Qualified: AEC-Q200 rating indicates suitability where enhanced component reliability verification is required.

Why Choose UKA1A101MDD?

UKA1A101MDD combines compact form factor and audio-focused electrical characteristics from Nichicon's UKA series to address filtering and decoupling needs in high-grade audio and temperature-challenged designs. Its defined loss tangent, controlled leakage, and frequency-dependent ripple ratings make performance predictable across common audio and power-frequency scenarios.

This capacitor is well suited to engineers needing a through-hole, radial-lead solution with clear endurance and thermal specifications (−55°C to +105°C, 2,000 hours at 105°C). The AEC-Q200 rating further supports designs where validated component reliability is part of the specification.
