UKT1H330MDD

The UKT1H330MDD is a 33 µF, 50 V aluminum electrolytic capacitor in a compact radial‑lead can designed for audio equipment. Built for wide temperature operation and reliable endurance, it combines low dissipation and measurable ripple handling for power and signal applications within audio systems.

This radial, polarized capacitor is optimized for engineers needing a small footprint (φ5 × 11 mm / 1.1 × 0.5 cm) solution with 2 mm lead spacing, RoHS compliance, and AEC‑Q200 qualification for applications that require established component reliability.

Key Features

• Capacitance and Voltage — 33 µF rated capacitance at 50 V with ±20% tolerance (at 120 Hz, 20°C) for predictable charge storage.
• Low loss — tan δ 0.14 maximum at 20°C, 120 Hz, contributing to lower dissipation in audio circuits.
• Ripple current capability — 90 mA at 120 Hz (low frequency) and 180 mA at 10 kHz (high frequency) for handling supply ripple across audio bandwidths.
• Leakage current — 49.5 µA specified leakage current, supporting stable bias conditions in DC‑coupled stages.
• Temperature and endurance — Rated for −55°C to +105°C operation with a 1000‑hour endurance at 105°C.
• Package and mounting — Radial lead can, φ5 × 11 mm (1.1 × 0.5 cm), 2 mm lead spacing; supplied bulk (no terminal forming) / bag packing.
• Compliance and qualification — RoHS compliant and AEC‑Q200 qualified for designs that require recognized reliability credentials.

Typical Applications

• General audio equipment — Designed for use in consumer and professional audio systems where stable capacitance and low dissipation matter.
• Audio power supply smoothing — Compact radial package with specified ripple current capability for local supply decoupling in audio modules.
• Audio circuitry requiring wide temperature operation — −55°C to +105°C rating supports designs exposed to varied thermal environments.

Unique Advantages

• Compact radial can — φ5 × 11 mm footprint (1.1 × 0.5 cm) and 2 mm lead spacing allow dense board placement in space‑constrained audio assemblies.
• Measurable low dissipation — tan δ 0.14 at 20°C/120 Hz reduces internal heating and preserves audio fidelity in sensitive circuits.
• Dual-frequency ripple handling — Specified ripple current at both 120 Hz and 10 kHz supports performance across power‑supply and audio frequency ranges.
• High‑temperature endurance — 1000 hours at 105°C provides predictable long‑term behavior in sustained thermal conditions.
• Industry qualification — AEC‑Q200 qualification and RoHS compliance help streamline qualification efforts for reliability‑focused designs.
• Polarized design for DC bias — Intended for applications where correct polarity and compact energy storage are required.
