UFW1V330MDD

The UFW1V330MDD is a Nichicon UFW series aluminum electrolytic capacitor in a radial-lead can, specified for audio equipment. It provides 33 µF capacitance at a 35 V rated voltage in a compact φ5 × 11 mm package with 2 mm lead spacing.

Designed for audio-focused designs, the part offers a controlled loss angle (tan δ 0.14 at 35 V, 120 Hz), defined leakage current, and ripple-current capability across low and high frequencies, making it suitable where stable smoothing and decoupling are required within a −40 °C to 85 °C operating range.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance, suitable for mid-voltage audio circuits.
• Compact Radial Package — φ5 × 11 mm can with 2 mm lead spacing in a radial-lead mounting style for through-hole PCB layouts.
• Audio-oriented Electrical Loss — Tan δ rated at 0.14 (35 V, 120 Hz) to characterize AC loss behavior in audio-frequency applications.
• Ripple Current Performance — Rated ripple current of 105 mA at 120 Hz and 210 mA at 10 kHz, enabling handling of both low- and high-frequency ripple conditions.
• Leakage Current Specification — Specified leakage current value of 34.65 µA, providing predictable DC leakage behavior for bias-sensitive circuits.
• Endurance & Temperature Range — 2000 hours endurance at 85 °C and operating temperature range from −40 °C to 85 °C for stable long-term operation under elevated temperature stress.
• Polarized, Through-Hole Mounting — Polarized device with radial leads for conventional through-hole assembly and repairability.

Typical Applications

• Audio equipment — Component choice for audio-focused circuitry where the UFW series specification supports audio system requirements.
• Power supply smoothing in audio circuits — Provides defined ripple-current handling (105 mA @120 Hz, 210 mA @10 kHz) and capacitance for supply decoupling and filtering tasks.
• Signal-chain support in audio modules — Compact radial form factor and controlled tan δ help maintain predictable performance in audio subassemblies operating across −40 °C to 85 °C.

Unique Advantages

• Audio-focused specification: Part of Nichicon’s UFW series, specified for audio equipment, with loss and endurance characteristics aligned to audio applications.
• Broad frequency ripple handling: Defined ripple-current ratings at both 120 Hz and 10 kHz enable use where both low- and high-frequency ripple are present.
• Compact footprint for through-hole designs: φ5 × 11 mm can and 2 mm lead spacing deliver a small, serviceable capacitor for dense PCB layouts.
• Predictable long-term behavior: 2000 hours endurance at 85 °C and specified limits for capacitance change, tan δ, and leakage current reduce uncertainty during design and validation.
• Measured leakage and loss data: Explicit leakage current (34.65 µA) and tan δ (0.14 at 35 V, 120 Hz) support accurate BOM-level electrical budgeting.
