UFW1A103MHD

The UFW1A103MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, engineered for audio equipment and related low-voltage power applications. It delivers large bulk capacitance in a compact φ16 × 35.5 mm can with through-hole radial leads for straightforward assembly and replacement.

Designed for applications that require substantial energy storage and ripple handling at low voltages, the part combines a 10 000 µF capacitance with a 10 V rating, specified endurance, and defined ripple-current performance across low and high frequencies.

Key Features

• High capacitance: 10 000 µF rated capacitance provides substantial bulk energy storage for smoothing and reservoir duties in power rails.
• Low-voltage rating: 10 V rated voltage suited to low-voltage audio and supply applications.
• Tolerance: ±20% capacitance tolerance (at 120 Hz, 20 °C) for predictable filtering performance.
• Loss tangent (tan δ): Specified tan δ of 0.38 to characterize dielectric losses for system-level power-loss estimates.
• Endurance / Lifetime: 2000 hours at 85 °C life rating; after the rated-life test the capacitor meets specified limits for capacitance change (within ±20%), tan δ (≤200% of initial specified value), and leakage current (≤ initial specified value).
• Ripple current capability: 2.5 A at 120 Hz and 2.875 A at 10 kHz to support both low- and high-frequency ripple demands.
• Operating temperature range: −40 °C to +85 °C for operation across common commercial and industrial temperature environments.
• Package and mounting: Radial, can-style package with φ16×35.5 mm dimensions, 7.5 mm lead spacing, and polarized leads for through‑hole mounting. Supplied in bulk/bag packing.
• Product status: End of Life.

Typical Applications

• Audio power supplies: Bulk energy storage and smoothing for low-voltage audio amplifiers and preamplifier rails.
• Power-supply filtering: Reservoir and decoupling in low-voltage DC power rails where high capacitance is required in a through-hole form factor.
• Replacement and repair: Direct-fit radial-lead option for servicing legacy or existing boards that accept a φ16×35.5 mm can with 7.5 mm lead spacing.

Unique Advantages

• Large bulk capacitance in a compact can: 10 000 µF in a φ16×35.5 mm package reduces board area compared with multiple smaller capacitors.
• Defined ripple performance across frequencies: Specified ripple current at 120 Hz and 10 kHz supports designers addressing both mains‑frequency and higher‑frequency ripple scenarios.
• Through-hole simplicity: Radial lead mounting simplifies mechanical retention and replacement for serviceable or hand‑assembled designs.
• Endurance characterized to 85 °C: 2000 h life test and clear post‑test acceptance criteria provide measurable reliability metrics for lifecycle planning.
• Clear mechanical specification: φ16×35.5 mm dimensions and 7.5 mm lead spacing enable straightforward mechanical integration and footprint definition.
• Audio-focused series: Part of Nichicon’s UFW series specified for audio equipment, matching application expectations for audio power circuitry.
