UKL1C330KDD

The UKL1C330KDD is a radial-lead, low-leakage aluminum electrolytic capacitor designed for compact, polarized DC applications. With a rated capacitance of 33 µF and 16 V working voltage, it targets circuits where low leakage, small footprint and reliable ripple handling are important—particularly in audio and related consumer-electronics uses.

Key attributes include a low leakage current, defined ripple-current capability at both low and high frequencies, and an operating temperature range of –40 °C to 85 °C with a 2000-hour endurance at 85 °C.

Key Features

• Capacitance and Tolerance – 33 µF nominal capacitance with ±10% tolerance (K), suitable for decoupling and coupling duties where defined capacitance is required.
• Rated Voltage – 16 V DC rated voltage for low-voltage electronics and signal circuits.
• Low Leakage – Specified leakage current of 1.056 µA, helping to preserve bias stability in sensitive circuits.
• Ripple Current Capability – Low-frequency ripple current of 100 mA at 120 Hz and high-frequency capability of 200 mA at 10 kHz to support both power-line and higher-frequency decoupling.
• Endurance and Temperature Range – Rated for 2000 hours at 85 °C and operating from –40 °C to 85 °C, enabling reliable operation across typical consumer and industrial ambient conditions.
• Radial Lead, Polarized Package – Radial can package, polarized, with 2.0 mm lead spacing (±0.5 mm), intended for through‑hole mounting.
• Compact Size – Small form factor with dimensions φ5 × 11 mm length (L) and seated height up to 1.1 cm, appropriate for tight-board-area designs.
• RoHS Compliant – Complies with RoHS requirements for restricted substances.
• Packaging Options – Available in bulk (no terminal forming) and bag packing for flexible assembly workflows.

Typical Applications

• Audio – Low-leakage and stable capacitance make the capacitor suitable for audio signal coupling, power‑supply decoupling and bias stabilization in audio circuitry and consumer audio products.

Unique Advantages

• Low Standby Losses: The 1.056 µA leakage current reduces unwanted drain on DC bias rails, preserving performance in sensitive analog and bias networks.
• Dual-Frequency Ripple Handling: Rated ripple currents at both 120 Hz and 10 kHz (100 mA / 200 mA) allow effective suppression of power-line hum and higher-frequency switching noise.
• Compact Through-Hole Form Factor: The φ5 × 11 mm radial can and 2.0 mm lead spacing enable space-efficient through-hole implementations where board real estate is constrained.
• Engineered for Elevated Temperatures: 2000-hour endurance at 85 °C supports sustained operation in warm environments common to enclosed consumer electronics.
• Consistent Electrical Specified Tolerance: ±10% capacitance tolerance provides predictable performance for filter and timing networks.
