UKA1C330MDD

The UKA1C330MDD is a radial-lead aluminum electrolytic capacitor designed for compact, wide-temperature electronic applications. This polarized φ5×11L can provides 33 µF nominal capacitance at a 16 V rating with ±20% tolerance, delivering reliable filtering and decoupling in space-constrained PCB layouts.

Engineered for robust temperature performance (–55°C to 105°C) and endurance (2000 hours at 105°C), the component targets high-grade audio and other electronics where stable capacitance, controlled leakage and ripple performance are required. The part carries an AEC-Q200 rating and is supplied in a radial can with 2 mm lead spacing.

Key Features

• Capacitance and tolerance — 33 µF nominal capacitance with ±20% tolerance suitable for general-purpose filtering in compact designs.
• Voltage rating — Rated at 16 V to support low-voltage analog and power circuits.
• Wide temperature range — Rated for operation from –55°C to 105°C to maintain performance across harsh thermal environments.
• Endurance and reliability — 2000 hours life at 105°C as specified for long-term stability under elevated temperature stress.
• Ripple current capability — 65 mA at 120 Hz (low frequency) and 130 mA at 10 kHz (high frequency) to handle AC ripple in power and audio paths.
• Low leakage — Specified leakage current of 15.84 µA to minimize DC losses in sensitive circuits.
• Package and mounting — Radial lead (can) form factor, φ5×11L size with 2 mm lead spacing for through-hole mounting and compact board placement.
• Qualification — AEC-Q200 listed rating for components requiring that level of passive component qualification.
• Polarized device — Designed for correct polarity installation in DC circuits.
• Product lifecycle — Part is listed with End of Life status; verify availability and lifecycle requirements before specifying in new designs.

Typical Applications

• High-grade audio equipment — Provides decoupling and filtering where stable capacitance and controlled leakage support audio signal integrity across temperature ranges.
• Wide-temperature electronics — Suitable for assemblies that must operate from –55°C to 105°C while retaining capacitance and ripple handling.
• Compact through-hole designs — Radial φ5×11L package and 2 mm lead spacing enable placement in space-constrained boards for small form-factor applications.

Unique Advantages

• Wide operating temperature span: –55°C to 105°C rating helps preserve performance in harsh or variable thermal environments.
• Long-term high-temperature endurance: 2000 hours at 105°C offers predictable aging characteristics for designs exposed to elevated temperatures.
• Measured ripple performance: Separate low- and high-frequency ripple ratings (65 mA at 120 Hz, 130 mA at 10 kHz) allow designers to evaluate performance across typical audio and switching frequencies.
• Low leakage current: 15.84 µA nominal leakage minimizes DC offset and standby losses in sensitive circuits.
• Compact radial footprint: φ5×11L can with 2 mm lead spacing fits tight through-hole layouts while keeping mounting and replacement straightforward.
• AEC-Q200 listing: Meets the component-level qualification listed in the product data for applications that require that rating.
