UKA1C101MDD

The UKA1C101MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UKA series, specified at 100 µF and 16 V. It is designed for low-voltage audio and general-purpose smoothing/decoupling applications where wide temperature range, low leakage and reliable ripple performance are required.

Key attributes include a wide operating temperature span of −55°C to 105°C, AEC-Q200 rating for reliability, and a 2000-hour endurance rating at 105°C, delivering stable performance in demanding environments.

Key Features

• Capacitance & Tolerance 100 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable charge storage in low-voltage circuits.
• Rated Voltage 16 V rating suitable for a wide range of low-voltage power and audio circuits.
• Temperature & Endurance Operating range −55°C to 105°C and endurance of 2000 hours at 105°C, offering long-term stability across harsh thermal conditions.
• Low Leakage Specified leakage current of 48 µA, minimizing idle current draw and supporting low-noise designs.
• Ripple Current Performance 115 mA at 120 Hz and 172.5 mA at 10 kHz (rms) for effective smoothing of low- and high-frequency ripple components.
• Package & Mounting Compact radial can (φ5 × 11 mm) with 2 mm lead spacing for through-hole mounting and easy placement in dense board layouts.
• Quality & Series Design Part of Nichicon’s UKA series, produced to series specifications for audio-grade electrolytic performance and consistency.

Typical Applications

• Audio equipment — Power supply smoothing and decoupling in high-grade audio circuits to help preserve signal integrity and reduce hum.
• Low-voltage power rails — Bulk capacitance and ripple suppression for 16 V and lower power domains in embedded electronics.
• Temperature-challenged environments — Electronic systems requiring reliable operation from −55°C to 105°C, including industrial and instrumentation equipment.

Unique Advantages

• Wide temperature capability: −55°C to 105°C rating enables use across broad environmental ranges without derating design expectations.
• Endurance-backed reliability: 2000 hours at 105°C endurance offers predictable performance retention for longer service intervals.
• Low leakage current: 48 µA leakage reduces quiescent current impact and supports low-noise, low-current designs.
• Frequency-aware ripple handling: Specified ripple currents at 120 Hz and 10 kHz provide guidance for both low- and high-frequency filtering needs.
• Compact radial can: φ5 × 11 mm size and 2 mm lead spacing balance board-space efficiency with through-hole mounting robustness.
• AEC-Q200 rated: Series-level AEC-Q200 rating indicates a design focus on component reliability and stress resistance.
