UKA1E101MED

The UKA1E101MED is a radial-lead aluminum electrolytic capacitor in the Nichicon UKA series, specified at 100 µF and 25 V. It is a polarized, compact can-style capacitor designed for use in audio equipment and similar electronic systems that require reliable smoothing and decoupling.

Engineered for a wide operating temperature range (−55 °C to 105 °C) and long endurance (2000 hours at 105 °C), the part combines compact dimensions (φ6.3 × 11 mm / L × D: 1.1 cm × 0.63 cm) with measurable ripple handling and low leakage for robust performance in demanding environments.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 25 V rated voltage and capacitance tolerance of −20% to +20% for predictable sizing in power and audio circuits.
• Wide Temperature Range — Operates from −55 °C to 105 °C, supporting designs that must withstand extreme ambient conditions.
• Endurance — Rated for 2000 hours at 105 °C, meeting endurance verification for long-term operation under elevated temperature stress.
• Ripple Current Performance — Low-frequency ripple current of 140 mA (120 Hz) and high-frequency ripple current of 210 mA (10 kHz), enabling effective handling of both mains-frequency and higher-frequency ripple components.
• Low Leakage & Dissipation — Leakage current specified at 75 µA and tangent of loss angle (tan δ) of 0.18 (measured at 20 °C, 120 Hz, 25 V), supporting low-noise and efficient operation in signal and power paths.
• Package & Mounting — Radial lead, can-style package (φ6.3 × 11 mm) with 2.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• AEC-Q200 Rated — Qualified to AEC-Q200 requirements for passive components, providing documented reliability criteria where that qualification is required.

Typical Applications

• High-grade Audio Equipment — Designed for use in audio systems where stable capacitance, low leakage, and controlled dissipation support clean power rails and low noise.
• Power Supply Smoothing and Decoupling — 100 µF capacitance and 25 V rating make this part suitable for smoothing and decoupling on audio and low-voltage power rails.
• Compact Through-hole Designs — Small φ6.3 × 11 mm can and radial-lead format for space-constrained PCB layouts that require through-hole components.

Unique Advantages

• Wide operating temperature window — −55 °C to 105 °C supports deployment across harsh thermal environments without derating outside documented limits.
• Measured ripple capability at multiple frequencies — Separate specifications for 120 Hz and 10 kHz ripple currents enable designers to assess performance for both low- and high-frequency ripple conditions.
• Long endurance at elevated temperature — 2000 hours at 105 °C provides quantified lifetime expectations for reliability planning.
• Compact radial can — φ6.3 × 11 mm size offers a small footprint for through-hole implementations while preserving useful capacitance and voltage rating.
• Low leakage and controlled dissipation — 75 µA leakage and tan δ = 0.18 (at 20 °C, 120 Hz, 25 V) help maintain signal integrity and reduce standby losses in sensitive circuits.
• AEC-Q200 qualification — Conformance to AEC-Q200 provides documented passive-component reliability criteria for designs that reference that standard.
