UFW2A2R2MDD

The UFW2A2R2MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, specified for audio equipment. It provides 2.2 µF capacitance at a 100 V rating in a compact φ5×11 mm can for space-constrained audio circuits.

Designed with audio-oriented loss characteristics and defined ripple and leakage specifications, this capacitor is suited for signal and power conditioning tasks within audio assemblies that require a polarized radial electrolytic solution and proven endurance up to 85 °C.

Key Features

• Electrical Rating: 2.2 µF capacitance with a 100 V rated voltage and tolerance of -20% to +20%.
• Audio-oriented loss characteristic: tanδ = 0.08 measured at 20 °C, 120 Hz (specified at the 100 V rating), supporting low-loss behavior in audio circuits.
• Ripple current capability: Defined ripple handling of 30 mA at 120 Hz (low frequency) and 60 mA at 10 kHz (high frequency), enabling both power-supply smoothing and higher-frequency decoupling roles.
• Low leakage: Leakage current specified as 6.6 µA, supporting stable bias conditions in sensitive audio stages.
• Reliability / Endurance: Rated life of 2000 hours at 85 °C with endurance limits specified for capacitance, tanδ and leakage after test.
• Mechanical and mounting: Radial lead can (φ5×11 mm), lead spacing 2.0 mm (±0.5 mm), polarized configuration for through-hole mounting and compact PCB layouts.
• Operating range: Specified operating temperature from -40 °C to +85 °C for a broad set of ambient conditions.
• Packaging: Available in bulk (no terminal forming) and bag packing options to suit prototyping and small-batch assembly.

Typical Applications

• Audio equipment power supply smoothing: Used for decoupling and smoothing in audio power rails where a 100 V rated, small-can electrolytic is required.
• Signal-stage decoupling and coupling in audio circuits: Employed where tight loss characteristics and low leakage help preserve signal integrity in amplifiers and preamplifiers.
• Compact audio module assemblies: Fits space-constrained radial through-hole designs in consumer and professional audio modules that use polarized electrolytic capacitors.

Unique Advantages

• High-voltage capability: 100 V rating provides margin for higher-voltage audio power rails and biased circuits.
• Audio-focused loss performance: Low tanδ at the rated voltage (0.08 at 120 Hz, 20 °C) supports reduced audible distortion risks tied to dielectric losses.
• Defined ripple performance across frequencies: Specified ripple currents at 120 Hz and 10 kHz allow designers to evaluate both low-frequency smoothing and higher-frequency decoupling needs.
• Compact radial form factor: φ5×11 mm can and 2.0 mm lead spacing enable dense through-hole layouts and simple mechanical mounting.
• Endurance-tested: 2000 hours at 85 °C endurance rating provides documented reliability data for thermal-stressed audio electronics.
• Low leakage for stable biasing: Leakage current specified at 6.6 µA supports stable operating points in sensitive circuits.
