UKA1H101MPD

The UKA1H101MPD is a miniature radial lead aluminum electrolytic capacitor from Nichicon’s UKA series, designed for high-grade audio equipment. It delivers 100 µF capacitance at a 50 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Engineered for demanding temperature and endurance requirements, this polarized capacitor offers a wide operating range (–55°C to 105°C) and a defined 2000 h endurance at 105°C, making it suitable for compact audio modules and other temperature-challenged electronics.

Key Features

• Electrical Performance  100 µF nominal capacitance with tolerance of −20% to +20% and a rated voltage of 50 V, providing predictable capacitance for audio circuit designs.
• Low Loss (tan δ)  tan δ = 0.14 (measured at 20°C, 120 Hz) to help maintain low dissipation in audio applications.
• Ripple Current Capability  Rated low-frequency ripple current of 190 mA (120 Hz) and high-frequency ripple current of 285 mA (10 kHz) to support varying ripple conditions in audio supplies.
• Leakage Current  Leakage current specified at 150 µA, enabling stable bias conditions in sensitive circuits.
• Reliability & Endurance  Endurance specified as 2000 hours at 105°C; after this test the capacitor meets specified limits for capacitance change, tan δ, and leakage current.
• Mechanical & Packaging  Miniature radial can: φ8 × 11.5 mm size, lead spacing 3.5 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Operating Temperature Range  Rated for −55°C to 105°C, supporting wide ambient and thermal conditions common in high-grade audio equipment.
• Quality Standard  Part of the UKA series with AEC-Q200 listed in specifications, indicating compliance with that program’s requirements where specified.

Typical Applications

• High‑grade Audio Equipment  Designed for use in high-grade audio modules where compact, polarized aluminum electrolytic capacitors are required.
• Compact Audio Assemblies  Small footprint (φ8 × 11.5 mm) and radial lead format make this capacitor suited to space-constrained audio boards and modules.
• Temperature‑challenged Electronics  Wide operating temperature (−55°C to 105°C) and 2000 h endurance at 105°C make it appropriate for designs exposed to elevated temperatures.

Unique Advantages

• Compact form factor: Small φ8 × 11.5 mm can and narrow 3.5 mm lead spacing reduce board space and ease placement in dense audio PCBs.
• Designed for audio performance: Low loss (tan δ = 0.14 at 120 Hz) supports low dissipation in audio signal environments.
• Robust ripple handling: Defined low- and high-frequency ripple current ratings (190 mA at 120 Hz, 285 mA at 10 kHz) enable predictable behavior under dynamic supply conditions.
• Wide thermal range and endurance: −55°C to 105°C rating and 2000 h life at 105°C provide long-term stability in thermally demanding applications.
• AEC-Q200 listed: Inclusion of AEC-Q200 in the specifications supports use where that quality program is required.
• Flexible packaging: Available in bulk (no terminal forming) or bag packing to match assembly and inventory workflows.
