UFW1H2R2MDD

The UFW1H2R2MDD is a Nichicon UFW-series aluminum electrolytic capacitor in a radial-lead can optimized for audio equipment. It provides a 2.2 µF capacitance at a 50 V rating with polarized terminals and a compact φ5 × 11 mm package (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing.

Designed for audio applications, this part combines a ±20% capacitance tolerance, rated endurance of 2000 hours at 85°C, and defined ripple-current performance to meet compact audio circuit design requirements. Note: this part is at End of Life status.

Key Features

• Capacitance & Voltage: 2.2 µF nominal capacitance at a 50 V rated voltage with a tolerance of ±20% (120 Hz, 20°C).
• Audio-focused Series: Part of Nichicon’s UFW series specified "for audio equipment", aligning the component’s design intent with audio circuitry applications.
• Temperature & Endurance: Operating temperature range of −40°C to +85°C and rated endurance of 2000 hours at 85°C, with specified limits for capacitance change, tan δ, and leakage after the endurance test.
• Low-temperature Stability: Documented impedance characteristics at low temperatures for the series: Z(−25°C)/Z(+20°C) = 2 and Z(−40°C)/Z(+20°C) = 3 (50 V column).
• Leakage Current Specification: Leakage current defined by the series specification: after 1 minute ≤ 0.03·C·V (µA) and after 2 minutes ≤ 0.01·C·V (µA).
• Loss Angle (tan δ): Series tan δ limit for 50 V is specified at 0.12 (measurement at 120 Hz, 20°C), providing a defined dissipation characteristic.
• Ripple Current Performance: Rated ripple current of 23 mA at 120 Hz and 46 mA at 10 kHz for this part, supporting AC and supply decoupling conditions typical in audio electronics.
• Package & Mounting: Radial lead, can-style package with φ5 × 11 mm dimensions and 2 mm lead spacing for compact, through-hole PCB layouts.

Typical Applications

• Audio Equipment — Intended for use in audio equipment designs as part of power decoupling, filtering, or other polarized capacitor functions within audio-focused circuits.
• Audio Electronics — Suited to compact audio circuit boards where a small radial electrolytic is required and series specifications for endurance and ripple are needed.
• Audio System Modules — Applicable in modules and subassemblies of audio products that specify UFW-series aluminum electrolytics for consistency across designs.

Unique Advantages

• Audio-oriented specification: Part of the UFW series labeled for audio equipment, aligning selection with audio design requirements.
• Compact radial can: φ5 × 11 mm package and 2 mm lead spacing allow installation in space-constrained through-hole boards while maintaining polarized electrolytic performance.
• Defined endurance at elevated temperature: 2000 hours at 85°C with specified limits for capacitance, tan δ, and leakage gives predictable lifecycle behavior under rated stress.
• Measured ripple capability: Explicit ripple current ratings at 120 Hz and 10 kHz provide designers with verifiable AC performance data for decoupling and smoothing tasks in audio circuits.
• Low leakage behavior: Leakage current defined by JIS-style limits (0.03·C·V / 0.01·C·V) supports predictable bias current budgeting in designs.
• Low-temperature performance data: Series impedance ratios at −25°C and −40°C (relative to +20°C) offer guidance for designs exposed to cold operating conditions.
