UKT1A331MPD

The UKT1A331MPD is a radial-lead aluminum electrolytic capacitor designed for audio equipment and related electronics. It delivers 330 µF at 10 V in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing, combining high ripple capability, wide temperature tolerance, and defined endurance for reliable performance in demanding audio environments.

Engineered for applications that require robust decoupling and smoothing at low voltages, this capacitor offers measurable ripple-handling and leakage characteristics along with AEC-Q200 qualification for elevated reliability expectations.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 10 V rated voltage, suitable for low-voltage audio power circuits.
• Ripple Current Performance — 240 mA ripple current at 120 Hz (low frequency) and 360 mA at 10 kHz (high frequency), supporting both power-supply smoothing and higher-frequency decoupling needs.
• Low Leakage — Specified leakage current of 99 µA, providing predictable idle current behavior in bias-sensitive audio circuits.
• Temperature & Endurance — Operational range from −55°C to +105°C and rated for 1000 hours at 105°C, enabling stable performance across wide ambient and elevated-temperature conditions.
• Packaging & Mounting — Radial lead, can-style package (φ8 × 11.5 mm) with 3.5 mm lead spacing for through-hole PCB mounting and straightforward assembly.
• Tolerance & Polarity — ±20% capacitance tolerance and polarized construction for correct circuit placement and predictable filtering behavior.
• Reliability & Standards — AEC-Q200 rated and RoHS compliant, supporting use where component-level qualification and environmental compliance are required.

Typical Applications

• Audio Amplifiers — Power-supply decoupling and smoothing where 330 µF at 10 V and high ripple capability help maintain stable supply rails for low-voltage amplifier stages.
• Consumer & Portable Audio — Bulk decoupling and energy storage in compact audio devices that benefit from the φ8 × 11.5 mm can and 3.5 mm lead spacing.
• Professional Audio Equipment — Use in modules that require extended temperature range (−55°C to +105°C) and 1000-hour endurance at elevated temperature for consistent performance.

Unique Advantages

• Measured ripple capability: 240 mA at 120 Hz and 360 mA at 10 kHz enables both low- and high-frequency ripple handling tied to the component’s specifications.
• Wide operating temperature: −55°C to +105°C rating allows deployment across broad environmental conditions without exceeding specified limits.
• Compact radial can: φ8 × 11.5 mm package with 3.5 mm lead spacing eases placement in dense PCB layouts while retaining substantial capacitance.
• Defined endurance: 1000 hours at 105°C provides a quantified lifetime metric for thermal-stress planning and reliability assessments.
• Qualified reliability: AEC-Q200 rating supports designs that require component-level quality assurance and traceable qualification.
• Low leakage: 99 µA leakage current delivers predictable standby current for bias-sensitive audio circuits.
