UKT1E222MHD

The UKT1E222MHD is a radial-lead aluminum electrolytic capacitor designed for general audio equipment and other electronics that require high capacitance with wide operating temperature capability. This 2.2 mF, 25 V polarized capacitor combines high capacitance density with a wide temperature range of -55°C to 105°C and an endurance rating of 1000 hours at 105°C.

Its characteristics—large capacitance, robust ripple-current handling, AEC‑Q200 rating, and compact φ12.5 × 30.5 mm can package—make it suitable for designs that demand reliable smoothing, decoupling, and energy storage in challenging thermal environments.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) rated at 25 V for bulk energy storage and power-supply smoothing in compact form factors.
• Wide Temperature Range: Specified to operate from -55°C to 105°C, providing design headroom for applications exposed to extreme ambient temperatures.
• Endurance: 1000 hours at 105°C endurance rating to support long-term operation in high-temperature environments.
• Ripple Current Performance: Rated ripple current of 1.2 A at 120 Hz and 1.38 A at 10 kHz to handle AC ripple and reduce heating in power circuits.
• Electrical Characteristics: Capacitance tolerance ±20% and tangent of loss angle (tan δ) 0.20, suitable for audio and general-purpose power applications.
• Package & Mounting: Radial lead, can package with φ12.5 × 30.5 mm dimensions and 5 mm lead spacing; available in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• Quality & Compliance: AEC‑Q200 listed and RoHS compliant, supporting applications requiring industry-recognized reliability and environmental compliance.
• Production Status: Mass production availability for supply continuity in volume designs.

Typical Applications

• Audio Equipment: Bulk filtering and power smoothing in amplifiers, preamplifiers, and audio power supplies where wide temperature tolerance is required.
• Power Supply Filtering: Energy storage and ripple reduction in DC power rails for embedded and consumer electronics.
• Industrial Electronics: Decoupling and energy buffering in control and instrumentation modules operating across broad temperature ranges.
• Automotive Electronics: Use in automotive systems that require AEC‑Q200 qualified components for increased reliability under temperature and vibration stress.

Unique Advantages

• High Capacitance in a Compact Can: 2200 µF in a φ12.5 × 30.5 mm package provides substantial energy storage without large PCB area impact.
