UKL1E6R8MDD

The UKL1E6R8MDD is a radial-lead aluminum electrolytic capacitor engineered for low leakage performance. With a capacitance of 6.8 µF and a 25 V rating, this compact φ5 × 11 mm package is intended for audio and other small-signal electronic applications that require stable capacitance and low self-discharge.

Key attributes include very low leakage current, specified ripple current values at both low and high frequencies, RoHS compliance, and a rated operational range from −40 °C to 85 °C with a 2000-hour endurance at 85 °C.

Key Features

• Capacitance & Tolerance — 6.8 µF nominal with ±20% tolerance for predictable filtering and decoupling performance.
• Rated Voltage — 25 V working voltage suitable for a range of low-voltage electronics.
• Low Leakage Current — Specified leakage current of 0.34 µA, minimizing self-discharge in standby or low-current circuits.
• Ripple Current Performance — Rated low-frequency ripple current of 55 mA at 120 Hz and high-frequency ripple current of 110 mA at 10 kHz for handling AC components in audio and decoupling applications.
• Reliability & Endurance — 2000 hours life at 85 °C, providing extended service life within the specified temperature range.
• Package & Mounting — Radial lead, polarized can with a φ5 × 11 mm case and 2 mm lead spacing (±0.5 mm), available in bulk or bag packing for assembly flexibility.
• Environmental Compliance — RoHS compliant, meeting current restricted-substance requirements.

Typical Applications

• Audio — Designed for use in audio circuitry where low leakage and specified ripple handling are important for signal integrity and power smoothing.

Unique Advantages

• Reduced Self-Discharge: The low leakage current (0.34 µA) helps maintain charge over longer intervals in standby and low-current audio circuits.
• Dual-Frequency Ripple Capability: Separate ripple current ratings at 120 Hz (55 mA) and 10 kHz (110 mA) clarify performance across low- and high-frequency conditions important to audio and decoupling tasks.
• Compact Radial Can: φ5 × 11 mm footprint with 2 mm lead spacing fits constrained board layouts while preserving polarized electrolytic capacity.
• Wide Operating Range with Defined Endurance: Specified −40 °C to 85 °C operating range and 2000-hour endurance at 85 °C provide a clear reliability target for design planning.
• RoHS Compliant: Conforms to restricted-substance requirements for regulatory and environmental alignment.
