UKT1E4R7MDD

The UKT1E4R7MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKT series, specified at 4.7 µF with a 25 V rating. It is designed for audio equipment and other applications that require a compact polarized electrolytic capacitor with a wide operating temperature range.

Key electrical and reliability attributes include ±20% capacitance tolerance, low leakage current, frequency-dependent ripple performance (25 mA at 120 Hz, 50 mA at 10 kHz), AEC-Q200 qualification, RoHS compliance, and 1000 hours endurance at 105°C. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Voltage Rating — Rated for 25 V DC operation.
• Ripple Current Performance — Rated ripple current: 25 mA at 120 Hz (low frequency) and 50 mA at 10 kHz (high frequency), suitable for frequency-dependent ripple requirements.
• Low Leakage — Specified leakage current around 4 µA, supporting low-standby and low-loss applications.
• Thermal and Endurance — Operating temperature range −55°C to 105°C with endurance of 1000 hours at 105°C under rated voltage.
• Package & Mechanical — Compact radial can: φ5 × 11 mm (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing; supplied bulk (no terminal forming) or in bags.
• Polarized Construction — Standard polarized aluminum electrolytic capacitor for DC circuit use.
• Standards & Compliance — AEC-Q200 qualified and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio equipment — Designed for general audio equipment applications where a compact radial electrolytic capacitor with wide temperature tolerance and defined ripple performance is required.

Unique Advantages

• Wide temperature capability — Rated for −55°C to 105°C to support designs exposed to broad environmental ranges.
• Defined endurance — 1000 hours at 105°C gives predictable lifetime behavior for thermal-stressed designs.
• Frequency-aware ripple ratings — Separate low- and high-frequency ripple current specifications (25 mA at 120 Hz, 50 mA at 10 kHz) allow designers to match capacitor selection to application ripple spectra.
• Compact radial form factor — φ5 × 11 mm can and 2 mm lead spacing provide a small footprint for space-constrained boards.
• Low leakage current — Approximately 4 µA leakage supports low-loss and low-standby current designs.
• Quality and compliance — AEC-Q200 qualification and RoHS compliance support higher-reliability programs and regulatory requirements.
