UKL1H1R5KDD

The UKL1H1R5KDD is an aluminum electrolytic capacitor from Nichicon's UKL series, engineered for low leakage current in a compact radial-lead package. With a nominal capacitance of 1.5 µF at 50 V, small φ5 × 11 mm can size and 2 mm lead spacing, it addresses space-constrained audio circuitry and other compact electronic designs that demand stable bias and low standby loss.

Key design attributes include very low leakage current (0.2 µA), frequency-qualified ripple performance (16 mA at 120 Hz and 32 mA at 10 kHz), and a rated operating range of −40 °C to 85 °C with 2,000 hours endurance at 85 °C.

Key Features

• Capacitance & Tolerance: 1.5 µF nominal capacitance with ±10% tolerance for predictable charge storage and tight component matching.
• Rated Voltage: 50 V rating suitable for mid-voltage audio and signal circuits requiring reliable DC handling.
• Low Leakage Current: Leakage current specified at 0.2 µA, minimizing bias drift and preserving DC operating points in sensitive circuits.
• Ripple Current Performance: Rated low-frequency ripple of 16 mA at 120 Hz and high-frequency ripple of 32 mA at 10 kHz to support both mains-derived and high-frequency ripple environments.
• Temperature & Endurance: Operating range −40 °C to 85 °C with a lifetime/endurance rating of 2000 hours at 85 °C for dependable long-term performance.
• Package & Mounting: Radial lead, can-style package (φ5 × 11 mm) with 2 mm lead spacing (±0.5 mm) for straightforward through-hole assembly and compact board layouts.
• Polarized Design: Polarized electrolytic construction for use where DC polarity is defined in the circuit.
• RoHS Compliant: Meets RoHS environmental requirements.

Typical Applications

• Audio signal and bias circuits: Low leakage minimizes DC offset and preserves amplifier bias in preamplifiers, tone controls, and coupling stages.
• Audio power filtering: Frequency-qualified ripple ratings support filtering of both low-frequency mains ripple and higher-frequency switching components in audio power supplies.
• Compact consumer electronics: Small φ5 × 11 mm can and radial lead format simplify placement in space-constrained audio and portable devices.

Unique Advantages

• Preserves circuit bias: Extremely low leakage current (0.2 µA) reduces DC drift and helps maintain precise operating points in sensitive audio stages.
• Dual-frequency ripple capability: Separate low- and high-frequency ripple ratings (16 mA at 120 Hz, 32 mA at 10 kHz) provide predictable behavior across common audio and switching frequencies.
• Compact radial package: φ5 × 11 mm can size with 2 mm lead spacing enables compact board layouts without sacrificing electrolytic capacitance benefits.
• Reliable under temperature stress: Rated for −40 °C to 85 °C with 2000 hours endurance at 85 °C, suitable for sustained operation in typical consumer and professional audio environments.
• Regulatory compliance: RoHS compliant to meet environmental requirements.
