UKT1A333MRD

The UKT1A333MRD is a miniature aluminum electrolytic capacitor in a radial can package from Nichicon's UKT series, optimized for audio equipment. It delivers high bulk capacitance (33,000 µF) at a 10 V rating in a compact φ25 × 50 mm can with radial lead termination for through‑hole mounting.

Designed for demanding audio power and smoothing applications, this part offers wide operating temperature capability (‑55°C to 105°C), specified ripple current performance at both low and high frequencies, and AEC‑Q200 qualification and RoHS compliance to support robust, regulated designs.

Key Features

• High Capacitance (33 mF) — Provides substantial bulk energy storage for power filtering and smoothing in audio circuits.
• Rated Voltage 10 V — Suited for low‑voltage audio power rails and decoupling applications.
• Radial Lead, Can Package — φ25 × 50 mm can with 12.5 mm lead spacing (±0.5 mm) for straightforward through‑hole mounting and chassis installation.
• Wide Temperature Range — Specified for operation from ‑55°C to 105°C, with endurance rated 1000 hours at 105°C.
• High Ripple Current Capability — Low‑frequency ripple current 2.88 A (120 Hz) and high‑frequency ripple current 3.312 A (10 kHz), supporting demanding audio power supplies.
• Electrical Characteristics — Capacitance tolerance ±20%, dissipation factor (tan δ) 0.9 (measured at 20°C, 120 Hz, 10 V), and leakage current specified at 9,900 µA.
• Quality & Compliance — AEC‑Q200 listed and RoHS compliant, supporting designs that require recognized reliability and environmental compliance.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit assembly or prototyping workflows.

Typical Applications

• Audio Power Amplifiers — Bulk energy storage and smoothing for amplifier supply rails to reduce low‑frequency ripple and support dynamic audio peaks.
• Audio Equipment Power Supplies — DC link and reservoir capacitor for regulated and unregulated audio power rails in compact enclosures.
• Decoupling and Energy Reservoir — High capacitance decoupling for boards requiring stable low‑voltage audio supply under varying load.

Unique Advantages

• Large capacitance in a compact can: 33,000 µF in a φ25 × 50 mm radial package reduces board space compared with multiple smaller parts.
• Designed for audio environments: Electrical characteristics and ripple ratings are presented for both low and high frequency conditions typical of audio power systems.
• Wide temperature and endurance specification: Rated for ‑55°C to 105°C with 1000 h endurance at 105°C for predictable life under elevated temperatures.
• Through‑hole radial format: Simple mechanical mounting and serviceability for prototyping, repairs, or equipment with higher power handling requirements.
• Compliance and qualification: AEC‑Q200 listing and RoHS compliance provide traceable quality and environmental conformance for regulated designs.
