UKA1H102MHD

The UKA1H102MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKA series designed for high-grade audio equipment and applications that require wide temperature tolerance and long operational life. It is a polarized, through-hole capacitor delivering 1000 µF at 50 V with specifications tuned for power smoothing, decoupling, and ripple handling in audio power supply circuits.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance rated at 50 V with ±20% tolerance, suitable for power-rail reservoir and smoothing applications.
• Low Loss — tan δ of 0.14 (measurement conditions per series data), offering reduced dissipation for improved thermal performance in audio power stages.
• Ripple Current Capability — Rated ripple current of 1040 mA at 120 Hz (low frequency) and 1196 mA at 10 kHz (high frequency), enabling effective AC ripple filtering across common power-supply frequencies.
• Leakage Current — Specified leakage current of 1500 µA, allowing predictable bias current considerations in circuit design.
• Temperature & Lifetime — Wide operating temperature range from −55°C to 105°C and a rated life of 2000 hours at 105°C for sustained performance under elevated temperatures.
• Package & Mounting — Radial lead (can) package with case dimensions φ12.5 × 30.5 mm, 5 mm lead spacing; supplied in bulk/bag for volume production and through-hole assembly.
• Reliability Rating — Meets AEC-Q200 requirements as specified, reflecting series-level reliability characteristics.

Typical Applications

• High-grade audio equipment: Power supply reservoir and smoothing in professional and consumer audio amplifiers and preamplifiers to maintain stable rails and minimize audible ripple.
• Amplifier power rails: Bulk energy storage and decoupling for amplifier modules where sustained capacitance and ripple handling are required over temperature.
• Audio power filtering: EMI and low-frequency ripple attenuation in audio power supplies, leveraging the capacitor’s ripple current ratings and low dissipation factor.

Unique Advantages

• Designed for audio performance: Series positioning for high-grade audio equipment combined with 1000 µF capacitance supports stable power delivery where low noise and reliable smoothing are critical.
• High ripple tolerance: Dual ripple ratings for low- and high-frequency operation (1040 mA at 120 Hz; 1196 mA at 10 kHz) help reduce heating and improve longevity in real-world power supplies.
• Wide temperature margin: −55°C to 105°C operating range ensures operation across demanding environments and audio system enclosures.
• Long-term reliability: 2000 hours at 105°C rated life provides predictable lifecycle behavior for designs with extended thermal stress.
• Through-hole robustness: Radial lead can and 5 mm lead spacing simplify assembly for repairable, serviceable designs and robust mechanical mounting.
• Traceable qualification: Inclusion of AEC-Q200 in the product’s ratings denotes series-level reliability considerations useful for applications requiring defined component standards.
