UKT1E100MDD

The UKT1E100MDD is a miniature aluminum electrolytic capacitor from Nichicon's UKT series, designed specifically for general audio equipment. It is a polarized, radial-lead, can-style capacitor optimized for compact board-level audio applications.

With a 25 V rating, 10 µF capacitance, wide operating temperature range and AEC-Q200 qualification, this part delivers reliable decoupling and smoothing performance in audio-focused designs that require compact size and robust temperature tolerance.

Key Features

• Electrical Rating — 10 µF nominal capacitance at a rated voltage of 25 V with capacitance tolerance of −20% to +20%.
• Low-frequency and high-frequency ripple handling — Rated ripple current of 36 mA at 120 Hz and 72 mA at 10 kHz, enabling use in both low- and higher-frequency power circuits common in audio systems.
• Wide temperature range — Operates from −55°C to +105°C to support audio equipment used across varied environments.
• Durability and lifetime — Endurance specified at 1000 hours at 105°C; meets AEC-Q200 requirements for enhanced reliability.
• Low leakage characteristics — Datasheet leakage current limits: ≤0.03CV (µA) after 1 minute and ≤0.01CV (µA) after 2 minutes at 20°C, supporting stable bias behavior in audio circuits.
• Compact radial-can package — Radial lead, can-style construction with a small footprint (approx. L: 1.1 × D: 0.5 cm) for space-constrained PCBs.
• RoHS compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Audio equipment — Intended for general audio equipment where compact decoupling and smoothing are required in power and signal sections.
• Compact amplifier modules — Small radial-can format fits tight PCB layouts in amplifier and preamplifier designs.
• Audio electronics exposed to varied temperatures — Wide −55°C to +105°C operating range supports use in environments with significant temperature variation.

Unique Advantages

• AEC-Q200 qualified: Provides an added level of reliability testing and characterization for demanding applications.
• Wide operating temperature: −55°C to +105°C rating helps maintain performance across hot and cold conditions common in fielded audio devices.
• Compact footprint: Small L × D dimensions allow designers to save board space without sacrificing necessary capacitance for audio circuits.
• Measured ripple capability: Specified ripple currents at 120 Hz and 10 kHz offer predictable thermal and performance margins for both power rail smoothing and higher-frequency filtering.
• Controlled leakage: Datasheet leakage limits help ensure low bias current and predictable charge retention in audio signal paths.
• RoHS compliant: Supports environmental and regulatory requirements for modern electronics manufacturing.
