UKW1C101MDD

The UKW1C101MDD is a Nichicon UKW-series aluminum electrolytic capacitor designed for audio and AV equipment. It is a polarized radial-lead capacitor offering 100 µF capacitance with a 16 V rating and a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).

This part is optimized for audio applications within a compact φ5 × 11 mm radial can footprint, supporting a temperature range of −40°C to +85°C and rated endurance of 2000 hours at 85°C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 100 µF nominal at a rated voltage of 16 V with ±20% tolerance (120 Hz, 20°C).
• Low-loss Characteristic — tanδ (loss tangent) specified at 0.20 measured at 20°C and 120 Hz, supporting low dissipation in audio circuits.
• Ripple Current Capability — Rated low-frequency ripple current 155 mA at 120 Hz and high-frequency ripple current 232.5 mA at 10 kHz, suitable for smoothing and decoupling in power rails for audio electronics.
• Leakage Current — Specified leakage current of 48 µA.
• Endurance & Temperature Range — Life/Endurance specified as 2000 hours at 85°C; operating temperature −40°C to +85°C.
• Package & Mounting — Radial lead, can-style package with dimensions φ5 × 11 mm (L: 1.1 × D: 0.5 cm), lead spacing 2 mm (±0.5 mm), available in bulk or bag packing; polarized device.
• Series Design for Audio — Part of Nichicon’s UKW series developed for audio equipment, emphasizing a harmonious balance of sound quality via series electrolyte development.
• Regulatory — RoHS compliant.

Typical Applications

• Audio Equipment — Smoothing and decoupling in audio power supplies where stable capacitance and controlled loss (tanδ) contribute to consistent audio performance.
• AV Systems — Local energy storage and ripple suppression in small-form-factor AV modules and signal-processing boards.
• Power Supply Filtering — Bulk and local filtering on low-voltage DC rails where a 16 V rated, polarized electrolytic is required.

Unique Advantages

• Audio-focused electrochemistry: UKW series development targets a balanced sound signature, aligning component selection with audio design goals.
• Compact radial can: φ5 × 11 mm footprint and 2 mm lead spacing enable use in dense PCB layouts and space-constrained audio modules.
• Measured AC performance: Specified ripple currents at both 120 Hz and 10 kHz provide clear, verifiable limits for low- and high-frequency ripple handling.
• Defined endurance: 2000 hours at 85°C gives a quantifiable lifecycle metric for thermal-stressed designs.
• Clear electrical parameters: Explicit values for tanδ, leakage current, and capacitance tolerance support predictable circuit behavior and easier design validation.
• RoHS compliance: Supports environmental regulatory requirements for many commercial electronic products.
