UKL1E332KHD

The UKL1E332KHD is a radial-lead aluminum electrolytic capacitor offering 3.3 mF (3300 µF) capacitance with a 25 V rated voltage and a ±10% tolerance. It belongs to Nichicon’s UKL low-leakage series and is designed where high capacitance, controlled leakage, and measurable ripple-handling are required.

This part provides defined ripple-current capability at both low and high frequencies and is specified for operation from –40 °C to 85 °C with a rated endurance of 2000 hours at 85 °C. Status: End Of Life; this part is supplied in bulk (no terminal forming) or bag packing.

Key Features

• Capacitance & Tolerance — 3300 µF nominal capacitance with ±10% tolerance for predictable bulk energy storage and decoupling performance.
• Rated Voltage — 25 V DC rating suitable for a range of low-voltage power rails.
• Low Leakage Current — Specified leakage current of 165 µA, supporting applications that benefit from minimized standby current.
• Ripple Current Handling — Rated for 1.72 A at 120 Hz (low frequency) and 1.978 A at 10 kHz (high frequency), enabling reliable performance under AC ripple stress.
• Endurance & Temperature — Life rating of 2000 hours at 85 °C and an operating temperature range of –40 °C to 85 °C.
• Mechanical & Mounting — Radial lead can package with dimensions φ18 × 40 L and lead spacing 7.5 mm (±0.5 mm) for through-hole mounting.
• Polarized Design — Polarized aluminum electrolytic construction appropriate for DC applications that require polarity awareness.
• RoHS Compliance — Compliant with RoHS requirements for restricted substances.

Typical Applications

• Audio Equipment — Intended for audio applications where high capacitance and low leakage support stable power and signal-chain performance.
• Audio Power Stages — Suitable for circuits in audio amplifiers and related modules that require defined ripple-current capability and bulk energy storage.
• Audio System Power Decoupling — Used where a radial-lead electrolytic with measured endurance and temperature range is needed for decoupling and smoothing in audio assemblies.

Unique Advantages

• Low Leakage for Reduced Standby Loss: 165 µA specified leakage helps limit drain in applications sensitive to quiescent current.
• Dual-Frequency Ripple Specification: Rated ripple current figures at 120 Hz and 10 kHz give clear guidance for both power-line and higher-frequency ripple conditions.
• High Bulk Capacitance in a Through-Hole Can: 3300 µF in a φ18 × 40 L radial can provides substantial energy storage for power-stage requirements.
• Defined Endurance: 2000 hours at 85 °C allows designers to plan for long-term thermal/rate stress within the specified operating window.
• RoHS-Compliant Construction: Meets environmental substance restrictions for regulatory alignment.
• Clear Mechanical Footprint: φ18 × 40 L body with 7.5 mm lead spacing simplifies board layout for through-hole assemblies.
