UFW1J100MDD

The UFW1J100MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment and related electronic applications. It provides a 10 µF capacitance with a 63 V rated voltage in a compact φ5 × 11 mm can with 2 mm lead spacing.

Engineered for compact audio and through-hole designs, this polarized capacitor offers defined ripple-current performance at both low and high frequencies, low leakage current, and a 2000-hour endurance rating at 85°C for predictable aging and reliability planning.

Key Features

• Electrical performance — 10 µF capacitance with ±20% tolerance and a 63 V rated voltage; polarized for standard DC applications.
• Ripple current specs — Rated for 70 mA at 120 Hz (low frequency) and 140 mA at 10 kHz (high frequency), enabling designers to address both LF and HF ripple conditions.
• Low leakage — Specified leakage current of 18.9 µA, helping to minimize steady-state loss and support stable DC biasing in audio circuits.
• Reliability & endurance — 2000 hours life rating at 85°C with defined post-test limits for capacitance, tan δ and leakage as per the series endurance specification.
• Temperature range — Rated for operation from −40°C to +85°C to cover a broad set of ambient conditions.
• Compact radial package — φ5 × 11 mm can, radial lead (can) package with 2 mm lead spacing; supplied in bulk/bag packing with no terminal forming.
• Audio-focused series — Part of Nichicon’s UFW family, specified for audio equipment performance considerations.

Typical Applications

• Audio equipment — Power supply smoothing, decoupling and coupling in amplifiers and audio signal paths where low leakage and defined ripple handling matter.
• Compact consumer electronics — Small φ5 × 11 mm radial can fits tight PCB layouts in portable or space-constrained audio modules.
• Signal and power decoupling — Use where combined low-frequency and high-frequency ripple handling (70 mA at 120 Hz; 140 mA at 10 kHz) is required for stable operation.

Unique Advantages

• High voltage in a small footprint — 63 V rating in a compact φ5 × 11 mm package supports higher-voltage rails while conserving board space.
• Frequency-aware ripple performance — Specified ripple current at both 120 Hz and 10 kHz helps designers account for real-world LF and HF ripple stress.
• Low steady-state loss — 18.9 µA leakage current reduces DC bias shifts and minimizes power loss over time.
• Predictable life characteristics — 2000-hour endurance at 85°C provides a measurable basis for reliability planning and life-cycle expectations.
• Through-hole assembly friendly — Radial lead format with 2 mm lead spacing simplifies manual assembly and prototyping workflows.
• Audio-oriented specification — As part of the UFW series, the product’s specifications are aligned with audio equipment requirements.
