UFW1E101MED

The UFW1E101MED is a Nichicon UFW series aluminum electrolytic capacitor in a radial-lead can, specified for audio applications. It delivers 100 µF capacitance at a 25 V rating with a compact φ6.3 × 11 mm case and 2.5 mm lead spacing.

This part is built for audio equipment use and offers defined performance metrics including low leakage current, measurable ripple-current ratings at low and high frequencies, and a rated life of 2000 hours at 85°C. Note: this part is listed with End of Life status.

Key Features

• Electrical Performance — 100 µF capacitance with ±20% tolerance and a 25 V rated voltage provide predictable energy storage for audio circuits.
• Ripple Current Capability — Rated ripple currents of 185 mA at 120 Hz (low frequency) and 277.5 mA at 100 kHz (high frequency) support both power supply smoothing and higher-frequency decoupling.
• Low Leakage — Specified leakage current of 75 µA for reduced standby loss and stable bias behavior.
• Thermal and Lifetime Specs — Operational temperature range of −40°C to +85°C with endurance rated at 2000 hours at 85°C, per UFW series endurance specifications.
• Compact Radial Package — φ6.3 × 11 mm can with 2.5 mm lead spacing in a radial-lead mounting format for through-hole PCB assembly.
• Audio-focused Series — Part of Nichicon’s UFW series, designated for audio equipment applications and marked accordingly.

Typical Applications

• Audio equipment — Designed for use in audio devices where series designation and electrical characteristics are aligned to audio circuit needs.
• Power supply decoupling in audio systems — 25 V rating and 100 µF capacitance suitable for local energy reserve and smoothing in audio power rails.
• Through-hole PCB assemblies — Radial lead configuration and compact can size for conventional through-hole mounting in audio product boards.

Unique Advantages

• Clear life specification — Rated 2000 hours at 85°C, enabling predictable end-of-life planning in designs.
• Measurable ripple behavior — Provided ripple-current ratings at 120 Hz and 100 kHz allow designers to size capacitors for both low-frequency smoothing and higher-frequency decoupling.
• Low leakage current — 75 µA leakage supports lower standby losses and stable bias in signal-path circuits.
• Compact form factor — φ6.3 × 11 mm can and 2.5 mm lead spacing minimize board area while maintaining through-hole robustness.
• Frequency scaling data available — UFW series frequency coefficients for ripple current (for 100–470 µF: 50 Hz = 0.80, 120 Hz = 1.00, 300 Hz = 1.23, 1 kHz = 1.34, ≥10 kHz = 1.50) support predictable ripple-current adjustments across operating frequencies.

Why Choose UFW1E101MED?

UFW1E101MED combines the UFW series’ audio-oriented specification set—100 µF/25 V capacitance, defined ripple-current ratings at both low and high frequencies, low leakage, and a 2000-hour endurance at 85°C—in a compact radial can. These attributes make the part suitable for through-hole audio designs where predictable electrical behavior and a small footprint are required.

Although this specific part is at End of Life, its documented specifications provide a clear reference for replacement selection and design planning, backed by Nichicon’s UFW series technical data.
