UKL0J102KPD

The UKL0J102KPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKL series, engineered for low leakage and stable performance in audio circuitry. It provides 1000 µF capacitance at a 6.3 V rating in a compact φ10 × 20 mm can with 5 mm lead spacing.

Designed for audio-focused power smoothing, coupling and decoupling, the part balances high capacitance, defined ripple capability and longevity with a rated life of 2000 hours at 85°C. The device is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance at a rated voltage of 6.3 V, tolerance ±10% (K).
• Low Leakage Current — Specified leakage current 12.6 µA, supporting low-bias loss in hold-up and filter applications.
• Low Loss (tan δ) — tanδ 0.21 measured at 20°C, 120 Hz (φ10 × 20 mm case), helping maintain efficiency in audio paths.
• Ripple Current Capability — Low-frequency ripple current 650 mA at 120 Hz and high-frequency ripple current 747.5 mA at 10 kHz for power smoothing under dynamic loads.
• Thermal & Endurance — Rated operating range −40°C to +85°C with endurance of 2000 hours at 85°C.
• Package & Mounting — Radial lead can, φ10 × 20 mm, 5.0 mm lead spacing (±0.5 mm), supplied in Bulk or Bag packing.
• Regulatory — RoHS compliant.
• Lifecycle — Product status: End Of Life.

Typical Applications

• Audio equipment — Bulk supply smoothing and decoupling in preamplifiers, amplifiers and audio power rails where low leakage preserves bias stability.
• Power supply filtering for audio circuits — Smoothing ripple and transient currents in low-voltage audio power domains using the part's specified ripple current ratings.
• Signal coupling and decoupling — Use in coupling/decoupling stages where high capacitance in a compact radial-can package is required.

Unique Advantages

• High capacitance in a compact can: 1000 µF in a φ10 × 20 mm package saves board space while delivering substantial energy storage for audio rails.
• Low leakage supports audio bias stability: Leakage current of 12.6 µA helps maintain DC bias points and reduces unintended discharge in sensitive circuits.
• Defined ripple handling across frequencies: Rated ripple currents at 120 Hz and 10 kHz (650 mA and 747.5 mA) allow designers to size decoupling and filter stages with measurable performance.
• Wide operating temperature: −40°C to +85°C rating and 2000-hour endurance at 85°C provides predictable lifetime behavior in typical audio and consumer environments.
• Radial-lead convenience: 5 mm lead spacing and standard radial can package simplify through-hole assembly and replacement operations.
• RoHS compliant: Meets RoHS directive requirements for lead-free manufacturing environments.
