UKT1E331MPD

The UKT1E331MPD is a radial-lead aluminum electrolytic capacitor offering 330 µF capacitance at a 25 V rating. It is designed for general audio equipment and other electronics that require stable bulk capacitance across a wide temperature range.

Key attributes include a compact φ8×11.5 mm can, wide operating temperature from -55 °C to 105 °C, and endurance specified to 1000 hours at 105 °C—making it suitable for equipment subject to extended elevated-temperature operation.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 25 V and tolerance of -20% to +20%.
• Low Loss (tan δ) — tanδ = 0.18 measured at 20 °C, 120 Hz, supporting low dissipation in AC conditions typical of audio circuits.
• Ripple Current Capability — 290 mA at 120 Hz (low frequency) and 435 mA at 10 kHz (high frequency), enabling handling of AC ripple in power rails and decoupling applications.
• Leakage Current — Specified leakage current of 247.5 µA, supporting predictable bias behavior after voltage application.
• Thermal & Endurance — Rated operating range -55 °C to 105 °C with endurance of 1000 hours at 105 °C per datasheet endurance conditions.
• Package & Mounting — Radial lead can, size φ8×11.5 mm, lead spacing 3.5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Reliability & Compliance — Polarized aluminum electrolytic construction with AEC-Q200 rating and RoHS compliance for regulated and quality-conscious applications.

Typical Applications

• Audio equipment — Intended for general audio equipment use as noted in the product datasheet; suitable where stable bulk capacitance and wide temperature performance are required.
• Power supply filtering — Compact radial-lead package and defined ripple current ratings make it suitable for local bulk filtering in low-voltage power rails.
• Industrial electronics — Wide temperature range and 1000-hour endurance at 105 °C suit electronics exposed to elevated operating temperatures.

Unique Advantages

• Wide temperature capability: −55 °C to 105 °C rating preserves capacitance and reliability in harsh thermal environments.
• Defined high-frequency performance: Ripple current ratings specified at both 120 Hz and 10 kHz provide clear guidance for AC stress in low- and high-frequency applications.
• Compact radial can: φ8×11.5 mm footprint with 3.5 mm lead spacing offers space-efficient bulk capacitance for through-hole assemblies.
• Long endurance at elevated temperature: 1000 hours at 105 °C endurance provides predictable life characteristics for design planning.
• Industry reliability marking: AEC-Q200 rating and RoHS compliance indicate suitability for regulated production environments and reliability-focused programs.
