UKT1C330MDD

The UKT1C330MDD is a miniature radial aluminum electrolytic capacitor engineered for audio equipment. It provides 33 µF capacitance at a 16 V rating in a compact φ5 × 11 mm can with radial leads and 2 mm lead spacing.

Designed for broad temperature operation and endurance, the UKT1C330MDD combines a wide operating range (‑55 °C to 105 °C) with defined ripple handling and low leakage for stable performance in audio circuits and space-constrained designs. The part is RoHS compliant and carries an AEC-Q200 rating.

Key Features

• Capacitance & Voltage — Nominal 33 µF capacitance at a 16 V rated voltage with ±20% tolerance (120 Hz, 20 °C).
• Low Loss Characteristic — tanδ (DF) of 0.22 measured at 20 °C, 120 Hz for predictable signal behavior in audio paths.
• Ripple Current Performance — Low-frequency ripple current 65 mA (120 Hz) and high-frequency ripple current 130 mA (10 kHz) to support smoothing and decoupling tasks across audio bandwidths.
• Low Leakage — Specified leakage current of 15.84 µA for minimized bias disturbances in signal and bias circuits.
• Wide Temperature & Endurance — Operating temperature range from ‑55 °C to 105 °C with a rated endurance of 1000 hours at 105 °C.
• Compact Radial Package — Miniature φ5 × 11 mm can, radial lead mounting, 2 mm lead spacing (±0.5 mm) suited to through-hole PCB layouts where board space is limited.
• Compliance & Qualification — RoHS compliant and rated to AEC-Q200.
• Packaging & Availability — Supplied in bulk or bag packing; current product status: End Of Life.

Typical Applications

• General audio equipment — Filtering, decoupling and smoothing in consumer and professional audio circuits where compact radial electrolytics are required.
• Space-constrained audio modules — Small can size (φ5 × 11 mm) and radial lead format for compact PCB assemblies and module-level designs.
• High-temperature audio environments — Use in assemblies needing stable performance up to 105 °C and defined endurance for thermal stress conditions.

Unique Advantages

• Compact footprint: Small φ5 × 11 mm can and narrow lead spacing let designers save PCB area without sacrificing capacitance for audio circuits.
• Defined ripple capability: Specified ripple current values at both low and high frequencies support predictable thermal and performance budgeting in power and signal paths.
• Wide operating temperature: ‑55 °C to 105 °C range provides flexibility for designs exposed to varied thermal environments.
• Endurance specification: 1000 hours at 105 °C gives a quantifiable life expectation for thermal-stress planning and reliability assessments.
• Standards and compliance: RoHS compliance and AEC-Q200 rating support use in regulated supply chains and qualification workflows.
• Low leakage and controlled loss: Low leakage current and specified tanδ support stable biasing and low-noise signal chains in audio applications.
