UFW0J103MHD

The UFW0J103MHD is a Nichicon UFW series aluminum electrolytic capacitor in a radial-lead can designed for audio applications. It provides high capacitance (10,000 µF) at a low rated voltage (6.3 V) for bulk energy storage, smoothing and decoupling in audio power rails.

Engineered for long-term operation in equipment-level environments, this part offers a 2,000‑hour endurance at 85°C and an operating temperature range from −40°C to +85°C, making it suitable for a broad range of audio designs that require stable capacitance and ripple handling.

Key Features

• High Capacitance: 10,000 µF nominal capacitance for substantial bulk energy storage and low-frequency smoothing in audio power supplies.
• Low Rated Voltage: 6.3 V rated voltage tailored for low-voltage audio rails and preamp/power amp supply sections.
• Endurance and Temperature Range: Rated for 2,000 hours at 85°C with an operating range of −40°C to +85°C to support sustained operation in consumer and pro audio equipment.
• Tolerance and Loss: Capacitance tolerance of ±20% and a specified tan δ of 0.38 to characterize AC loss for design verification.
• Leakage Current: Specified leakage current of 4,800 µA for initial leakage budgeting in power-supply designs.
• Ripple Current Capability: Rated ripple current of 2.0 A at 120 Hz and 2.3 A at 10 kHz to address both low- and high-frequency ripple components found in audio supplies.
• Through‑Hole Radial Package: φ16 × 35.5 mm can with 7.5 mm lead spacing for robust mechanical mounting and compatibility with through-hole assemblies; supplied bulk/bag packed.
• Polarized Construction: Polarized electrolytic design appropriate for DC power rail decoupling and smoothing in audio circuits.

Typical Applications

• Audio Amplifiers: Bulk smoothing and power-rail decoupling for preamplifiers and power amplifiers where high capacitance at low voltage is required.
• Consumer and Professional Audio Equipment: Energy storage and ripple buffering in mixers, powered speakers, and audio interfaces to stabilize supply rails under dynamic load.
• Power Supply Filter Stages: Filtering and reservoir functions in low-voltage audio power supplies and ancillary circuitry.

Unique Advantages

• Large Energy Storage: 10,000 µF allows designers to reduce the number of parallel capacitors needed for bulk filtering, simplifying BOM and board space decisions.
• Designed for Audio Use: Specified ripple current values at both 120 Hz and 10 kHz support mixed-frequency ripple environments commonly encountered in audio power systems.
• Robust Thermal Endurance: 2,000 hours at 85°C provides predictable lifetime performance for equipment deployed in warm operating environments.
• Through-Hole Reliability: Radial leaded can (φ16 × 35.5 mm) with 7.5 mm lead spacing gives secure mechanical mounting and is straightforward to integrate into existing PCB layouts.
• Clear Electrical Parameters: Specified tan δ, leakage current, and tolerance figures enable accurate design margining and simulation for audio-grade power supplies.
