UFW1A101MDD

The UFW1A101MDD is a miniature aluminum electrolytic capacitor from Nichicon's UFW series, designed specifically for audio equipment. It is a polarized, radial-lead, can-style capacitor providing 100 µF capacitance at a 10 V rating in a compact footprint.

Engineered for audio applications, this part combines a compact package with defined ripple-current capability and a wide operating temperature range to support filtering, decoupling, and local power conditioning in space-constrained audio circuits.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 10 V rated voltage, suitable for low-voltage audio supply and signal circuitry.
• Tolerance — Capacitance tolerance of ±20% (specified at 120 Hz, 20°C), aligning with the UFW series specification for predictable design margins.
• Package & Mounting — Radial can package with radial lead mounting for through-hole assemblies and straightforward PCB implementation.
• Physical Size & Lead Spacing — Compact size (L: 1.1 × D: 0.5 cm) and 2 mm lead spacing to ease placement in tight layouts.
• Operating Temperature & Lifetime — Specified for operation from −40°C to +85°C with an endurance rating of 2000 hours at 85°C, consistent with series endurance data.
• Ripple Current Capability — Rated ripple current of 145 mA at 120 Hz and 217.5 mA at 10 kHz, enabling effective smoothing and decoupling across audio-relevant frequencies.
• Polarized — Polarized electrolytic construction for DC bus and coupling applications common in audio electronics.

Typical Applications

• Audio Equipment — Filtering and decoupling in amplifiers, preamplifiers, and DAC circuits where compact radial electrolytics are required.
• Portable Audio Devices — Local power conditioning in small enclosures where board space is limited and low-voltage capacitors are needed.
• Signal Path Support — Coupling/decoupling tasks in audio signal chains that demand stable capacitance and defined ripple-handling up to audio and near-audio frequencies.

Unique Advantages

• Compact footprint — Small L × D dimensions and tight lead spacing help fit this capacitor into dense PCB layouts typical of modern audio hardware.
• Audio-focused performance — Specified ripple-current values at 120 Hz and 10 kHz give clear guidance for design decisions in audio-frequency smoothing and decoupling.
• Wide operating temperature — −40°C to +85°C rating supports reliable performance across common environmental conditions for consumer and pro audio gear.
• Proven endurance — 2000 hours at 85°C endurance per series data provides a measurable basis for lifecycle planning in product designs.
• Radial lead convenience — Through-hole radial leads simplify prototyping, repairability, and mechanical mounting in EMI-sensitive audio assemblies.
• Nichicon UFW series pedigree — Part of the UFW family designed for audio equipment, offering consistent series-level specifications such as capacitance tolerance and temperature stability.
