UKT1E153MRD

The UKT1E153MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKT series, offering large bulk capacitance in a can-style radial package. Engineered for general audio equipment and similar power-smoothing roles, this part delivers 15,000 µF at a 25 V rating with polarized radial leads for through-hole mounting.

Key technical strengths include a wide operating temperature range of -55°C to 105°C, defined endurance of 1000 hours at 105°C, and quantified ripple-current capability across low and high frequencies—attributes that support energy storage and smoothing in demanding audio and power applications.

Key Features

• High Bulk Capacitance: 15,000 µF capacitance provides substantial energy storage for power-supply smoothing and decoupling in audio power stages.
• Rated Voltage & Tolerance: 25 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C, enabling predictable performance for design margin calculations.
• Thermal Range & Endurance: Operating temperature from -55°C to +105°C and 1000 hours endurance at 105°C, supporting sustained performance under elevated-temperature conditions.
• Defined Dissipation Factor (tan δ): tan δ of 0.46 measured at 20°C, 120 Hz, reflecting loss characteristics for this capacitance and voltage combination.
• Ripple Current Performance: Low-frequency ripple current of 2.75 A (120 Hz) and high-frequency ripple current of 3.1625 A (10 kHz), specified to guide thermal and RMS current budgeting.
• Package & Mounting: Radial, can-style package, φ22 × 50 mm case size with 10 mm lead spacing, supplied in bulk/bag packing for through-hole assembly.
• Leakage Current Specification: Leakage current specified at 11,250 µA (as provided), useful for standby and bias current considerations.
• Quality Rating: Rated AEC-Q200, indicating conformity with the series' specified reliability standard.

Typical Applications

• General Audio Equipment: Bulk energy storage and smoothing for power supplies in amplifiers and audio electronics where sustained capacitance and ripple handling are required.
• Audio Power Stages: Decoupling and reservoir capacitance to support transient current demands in audio output stages.
• Power Supply Filtering: Filtering and smoothing in through-hole power-supply designs that require high capacitance at moderate voltage.

Unique Advantages

• Substantial Energy Storage: 15,000 µF capacitance reduces voltage sag under load and increases hold-up in power circuits.
• Temperature-Endurance Balance: Rated for -55°C to +105°C with 1000 hours endurance at 105°C, enabling reliable operation across wide ambient conditions.
• Frequency-aware Ripple Ratings: Specified ripple currents at both low and high frequencies (2.75 A @120 Hz, 3.1625 A @10 kHz) help designers size thermal management and RMS current limits.
• Through-hole, Serviceable Form Factor: Radial can package (φ22×50 mm, 10 mm lead spacing) facilitates manual replacement and prototyping in discrete designs.
• Defined Electrical Loss Profile: Tangent of loss angle (tan δ) of 0.46 at 20°C/120 Hz for this capacitance/voltage combination gives a clear basis for AC loss and heating estimates.
• Documented Leakage Figures: Provided leakage current value supports low-frequency bias and standby current assessments.
