UKT0J222MPD

The UKT0J222MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UKT series designed for audio equipment. It delivers 2200 µF capacitance in a compact φ12.5 × 20 mm can with a 5 mm lead spacing, offering high bulk capacitance for power filtering and decoupling in audio circuits.

Engineered for wide temperature operation and endurance, this polarized capacitor supports an operating temperature range of −55°C to +105°C and a rated life of 1000 hours at 105°C. It is RoHS compliant and AEC‑Q200 qualified for demanding reliability environments.

Key Features

• Capacitance & tolerance: 2200 µF nominal capacitance with tolerance ±20% (−20%~20%), providing substantial energy storage for smoothing and decoupling tasks.
• Rated voltage: 16 V nominal rated voltage for common audio power-rail applications.
• Compact radial can package: φ12.5 × 20 mm can with radial lead mounting and 5 mm lead spacing (±0.5 mm), suitable for through‑hole PCB layouts where board space is limited.
• Thermal endurance: Operating from −55°C to +105°C with a rated endurance of 1000 hours at 105°C, designed for sustained performance in elevated-temperature audio equipment.
• Performance metrics: Low-frequency ripple current 920 mA and high-frequency ripple current 1150.8 mA (specified conditions), with a leakage current of 1056 µA, supporting effective ripple handling in power supply stages.
• Electrical loss: Dissipation factor (tan δ) 0.24 measured at 20°C and 120 Hz, allowing designers to assess AC loss for audio signal and power applications.
• Standards & compliance: RoHS compliant and AEC‑Q200 qualified, reflecting manufacturing and quality controls for reliability-focused designs.
• Packaging options: Available in bulk (no terminal forming) or bag packing to support different assembly workflows.

Typical Applications

• Audio equipment power supplies: Bulk decoupling and smoothing on audio amplifier rails where 2200 µF and 16 V ratings meet common rail requirements.
• Signal processing modules: Local energy storage in preamp and signal-chain circuits where compact, polarized capacitance is required.
• Consumer and professional audio systems: Through‑hole radial package suited for serviceable PCBs and compact enclosures in both consumer and pro audio products.

Unique Advantages

• High bulk capacitance in a small footprint: 2200 µF in a φ12.5 × 20 mm can reduces board area while delivering substantial energy storage for audio power stability.
• Wide thermal range and rated endurance: −55°C to +105°C operation and 1000 hours at 105°C provide predictable performance in heat‑exposed audio electronics.
• Designed for ripple-handling: Specified low- and high-frequency ripple current figures support effective filtering across audio-frequency and switching environments.
• AEC‑Q200 qualification: Qualification under AEC‑Q200 offers an added level of manufacturing and quality assurance for reliability-sensitive designs.
• RoHS compliance and supply options: RoHS status and bulk/bag packing choices simplify procurement and assembly planning.
• Through-hole serviceability: Radial lead format with defined lead spacing supports repairability and prototyping workflows common in audio product development.
