UKT1V4R7MDD

The UKT1V4R7MDD is a radial‑lead aluminum electrolytic capacitor engineered for audio applications. It provides 4.7 µF capacitance at a 35 V rating in a compact φ5 × 11 mm can, delivering a balance of size and performance for board‑level power and signal circuits in audio equipment.

Key value comes from its wide operating temperature range (−55°C to 105°C), defined endurance (1000 hours at 105°C), and electrical characteristics such as low dissipation factor and specified ripple current at multiple frequencies—making it suitable for designs that require stable behavior across temperature and frequency.

Key Features

• Electrical Performance — 4.7 µF capacitance at 35 V with ±20% tolerance, polarized design suitable for common audio circuit functions.
• Low Dissipation Factor — tanδ = 0.16 (max) at 20°C, 120 Hz, supporting lower losses in audio signal and power paths.
• Controlled Leakage — specified leakage current of 4.935 µA, enabling predictable bias behavior after voltage application.
• Ripple Current Ratings — 28 mA at 120 Hz (low frequency) and 56 mA at 10 kHz (high frequency) for defined ripple handling across common audio frequencies.
• Reliability & Endurance — 1000 hours life at 105°C and an operating temperature range of −55°C to 105°C for thermal robustness in demanding environments.
• Compact Radial Package — φ5 × 11 mm can with 2 mm lead spacing and radial lead mounting for through‑hole PCB assemblies and hand or wave soldering processes.
• Standards & Compliance — AEC‑Q200 rated and RoHS compliant, reflecting component qualification and environmental compliance noted in the product data.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit production handling preferences.

Typical Applications

• General Audio Equipment — Designed for audio systems where stable capacitance, low dissipation factor, and defined ripple handling are required across a wide temperature range.
• Audio PCB Assemblies — Compact radial package and 2 mm lead spacing simplify placement in through‑hole audio PCBs and serviceable designs.
• Temperature‑challenging Environments — The −55°C to 105°C rating and 1000 h endurance at 105°C support use in audio products exposed to wide thermal excursions.

Unique Advantages

• Compact footprint: φ5 × 11 mm can and 2 mm lead spacing save board space while keeping through‑hole robustness for assembly and repair.
• Frequency‑aware ripple capability: Separate ripple specifications for 120 Hz and 10 kHz (28 mA / 56 mA) help designers size capacitors for both power and higher‑frequency ripple conditions.
• Predictable electrical behavior: Low tanδ (0.16 at 120 Hz, 20°C) and a specified leakage current (4.935 µA) enable more accurate circuit bias and noise planning.
• Durability under heat stress: 1000 hours rated life at 105°C provides a quantifiable endurance metric for long‑term reliability planning.
• Industry qualification and compliance: AEC‑Q200 rating and RoHS compliance assist with supplier qualification and environmental requirements.
