UKT1H2R2MDD

The UKT1H2R2MDD is a radial-lead aluminum electrolytic capacitor designed for audio applications. It delivers a compact 2.2 µF capacitance at a 50 V rating with a design focus on wide temperature operation and long-term endurance.

Engineered for general audio equipment, this part combines low leakage, defined ripple-current capability and an extended operating temperature range to support stable performance in temperature‑challenging environments.

Key Features

• Electrical Performance: 2.2 µF capacitance rated at 50 V with ±20% tolerance; tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz.
• Ripple Current Capability: 20 mA at 120 Hz (low frequency) and 40 mA at 10 kHz (high frequency), enabling predictable behavior across common audio frequencies.
• Low Leakage: Typical leakage current specified at 4 µA, supporting low‑current audio circuits and minimizing bias drift.
• Reliability & Endurance: Rated for 1000 hours life/ endurance at 105°C, with endurance characteristics defined after restoration to 20°C.
• Wide Temperature Range: Operating range from −55°C to 105°C for stable performance across harsh thermal conditions.
• Compact Radial Package: φ5 × 11 mm case size (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing and radial-lead mounting in a can-style package; supplied in bulk (bag) packing.
• Compliance & Qualification: RoHS compliant and AEC‑Q200 rated, aligning to industry stress‑test qualifications for passive components.

Typical Applications

• General Audio Equipment: Suitable for use in audio circuits where a compact radial electrolytic capacitor is required and stable performance over −55°C to 105°C is needed.
• Audio Modules and Signal Paths: Applicable in audio subsystem designs that require a 50 V rated capacitor with low leakage and defined loss angle at audio‑range test conditions.
• Temperature‑Challenged Audio Systems: Useful where wide operating temperature and 1000 h endurance at elevated temperature are important for long-term reliability.

Unique Advantages

• Compact footprint: φ5×11 mm can and 2 mm lead spacing make it easy to integrate into dense audio PCBs without sacrificing rated voltage.
• Defined audio‑range loss characteristic: tan δ of 0.14 at 20°C, 120 Hz provides a known dissipation factor for predictable audio performance.
• Low leakage current: 4 µA leakage helps maintain bias stability in low-current audio stages and preamplifier circuits.
• Qualified for stress testing: AEC‑Q200 rating offers an added qualification layer for designs requiring industry stress‑test traceability.
• Endurance at elevated temperature: 1000 hours at 105°C demonstrates long-term stability under thermal stress.
• RoHS compliant: Meets environmental compliance requirements for lead‑free assemblies.
