UKT1A153MHD

The UKT1A153MHD is a high-capacitance radial lead aluminum electrolytic capacitor from Nichicon’s UKT series, designed for general audio equipment and other applications requiring large bulk energy storage. It provides 15,000 µF nominal capacitance at a 10 V rating in a compact φ18 × 40 mm can with 7.5 mm lead spacing.

This part combines large capacitance, substantial ripple-current capability, and a wide operating temperature range (−55℃ to 105℃), making it suitable for demanding power-smoothing and buffering roles in audio electronics and related systems. Note: this part is designated End Of Life.

Key Features

• High Capacitance — 15,000 µF nominal capacitance with tolerance −20% to +20% for bulk energy storage and smoothing in low-voltage power rails.
• 10 V Rated Voltage — Designed for low-voltage power supply applications where large capacitance at 10 V is required.
• Radial Lead, Can Package — φ18 × 40 mm can with 7.5 mm lead spacing (±0.5 mm), packaged in bulk or bag packing for through-hole assembly.
• Wide Operating Temperature — Rated for −55℃ to 105℃ to support operation across harsh thermal environments.
• Ripple Current Capability — Low-frequency ripple current 2.4 A at 120 Hz and high-frequency ripple current 2.76 A at 10 kHz for effective AC ripple handling.
• Endurance — Life rating of 1,000 hours at 105℃ for established high-temperature endurance characteristics.
• Electrical Loss and Leakage — Specified tan δ (DF) of 0.54 measured at 20℃, 120 Hz (10 V) and leakage current of 4,500 µA as provided in the part data.
• AEC-Q200 Rating — Part data lists AEC-Q200, indicating qualification to that reliability standard where specified.

Typical Applications

• Audio power supply smoothing — Bulk energy storage for amplifier and preamplifier rails, leveraging the 15,000 µF capacitance and available ripple-current ratings to stabilize low-voltage audio supplies.
• Peak power buffering — Local energy reservoir for transient demands in subwoofer and high-power audio stages to maintain supply stability during dynamic peaks.
• General audio equipment — Designed for use in consumer and professional audio electronics that require large-capacitance, through-hole capacitors in constrained form factors.

Unique Advantages

• Large energy density in a compact can — 15,000 µF in a φ18 × 40 mm radial can provides substantial capacitance for space-constrained through-hole designs.
• Robust ripple handling — Specified LF and HF ripple-current ratings (2.4 A at 120 Hz, 2.76 A at 10 kHz) support effective AC ripple dissipation in power stages.
• Wide temperature tolerance — −55℃ to 105℃ operating range enables deployment across broad environmental conditions without derating beyond specified limits.
• Proven endurance — 1,000-hour life at 105℃ provides a clear reliability baseline for thermal-stressed applications.
• Manufacturing-friendly packaging — Available in bulk or bag packing with standard radial lead spacing for straightforward through-hole assembly and handling.
• Qualification-oriented — Listing of AEC-Q200 in the product data points to use in applications where that level of qualification is part of the requirement set.
