UKA1C332MHD

The UKA1C332MHD is a Nichicon radial lead aluminum electrolytic capacitor offering 3300 µF capacitance at a 16 V rating. Designed for high-grade audio equipment and other electronics requiring robust bulk energy storage, it combines high capacitance, defined loss characteristics, and wide operating temperature range for reliable performance.

With a temperature range of −55°C to 105°C and a specified endurance of 2000 hours at 105°C, this radial can meets demanding thermal and lifetime requirements while providing strong ripple-current handling for power-filtering and decoupling roles.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C; rated voltage is 16 V.
• Loss Characteristics (Audio-focused) — Tangent of loss angle (tanδ) specified as 0.26 measured at 20°C, 120 Hz, supporting predictable audio-frequency behavior and power-filtering performance.
• Ripple Current Performance — Low-frequency ripple current of 1.27 A (120 Hz) and high-frequency ripple current of 1.4605 A, enabling effective smoothing in power rails and amplifier supplies.
• Leakage Current — Specified leakage current of 1584 µA, allowing designers to budget standby and bias currents accurately.
• Wide Temperature & Endurance — Operating range −55°C to 105°C with endurance specified at 2000 hours at 105°C for long-term reliability in temperature-stressed applications.
• Packaging & Mounting — Radial, can-style package (φ12.5×30.5L) with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for through-hole assembly workflows.
• AEC-Q200 Rated — Component carries an AEC-Q200 rating as specified, indicating qualification to the referenced reliability standard.

Typical Applications

• High-grade audio equipment — Bulk storage and power smoothing for amplifier power supplies and audio circuits where stable capacitance and defined loss characteristics matter.
• Power supply filtering — DC rail decoupling and bulk filtering in low-voltage (16 V) power systems that require high capacitance in a compact radial can.
• Industrial and temperature-challenged electronics — Use in devices operating across −55°C to 105°C that demand sustained performance and 2000-hour endurance at elevated temperature.

Unique Advantages

• High capacitance in a compact package — 3300 µF in a φ12.5×30.5 mm radial can provides substantial energy storage while minimizing board footprint.
• Predictable audio performance — Specified tanδ at 120 Hz and 20°C supports designers targeting consistent behavior in audio-frequency applications.
• Robust ripple-handling capability — Rated ripple currents at both low and high frequencies help ensure reliable smoothing under real-world load conditions.
• Wide operating range and endurance — −55°C to 105°C operation with 2000 hours rated life at 105°C supports long-term reliability in thermally demanding environments.
• Through-hole assembly friendly — Radial lead format with 5 mm lead spacing and bulk/bag packing options that fit established through-hole production processes.
• Qualified reliability — AEC-Q200 rating provides an added qualification datapoint for designs that require specified reliability standards.
