UEP1J221MHD

The UEP1J221MHD is a bi‑polarized aluminum electrolytic capacitor in a radial‑lead can, rated at 220 µF and 63 V. It is engineered for general‑purpose applications that require bipolar operation across a wide temperature range.

Designed for reliability in demanding environments, this part delivers specified ripple handling and endurance up to 1000 hours at 105°C while remaining RoHS‑compliant.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a rated voltage of 63 V and a tolerance of −20% to +20%.
• Bi‑Polar Construction: Bi‑polarized design suitable for applications that require non‑polar operation across positive and negative voltages.
• Wide Temperature Range: Specified operation from −55°C to +105°C to support designs that face broad ambient conditions.
• Ripple Current Performance: Low‑frequency ripple current of 405 mA at 120 Hz and high‑frequency ripple current of 607.5 mA at 10 kHz, with frequency coefficients defined in the series datasheet.
• Loss Characteristics: Tangent of loss angle (tan δ) of 0.12 measured at 20°C and 120 Hz for the 63 V rating, enabling predictable dissipation behavior.
• Leakage Current: Specified leakage current of 415.8 µA under stated measurement conditions.
• Endurance: Life rating of 1000 hours at 105°C (polarities inverted every 250 hours during the test) with defined limits for capacitance change, tan δ and leakage recovery.
• Form Factor & Mounting: Radial lead can, size φ16 × 25L (L: 2.5 × D: 1.6 cm), lead spacing 7.5 mm (±0.5 mm), shipped bulk or bag packing with no terminal forming.
• Regulatory: RoHS‑compliant construction.

Typical Applications

• General‑purpose power filtering: Use for smoothing and ripple handling in power circuits up to 63 V where bi‑polar operation and rated ripple currents are required.
• Temperature‑extreme environments: Suitable for systems that must operate from −55°C to +105°C while maintaining capacitance and leakage performance.
• Board‑level radial mounting: Radial lead format and compact φ16 × 25L can make it suitable for through‑hole assemblies requiring a bulk or bag packaging option.

Unique Advantages

• Bi‑polar operation: Enables use in circuits that encounter alternating polarities without the need for separate polarity management components.
• Wide thermal window: −55°C to +105°C rating provides design margin for systems exposed to extreme cold and heat.
• Defined ripple capability: Published ripple current values at 120 Hz and 10 kHz allow designers to match the capacitor to expected operating frequencies and thermal dissipation.
• Conservative endurance spec: 1000 hours at 105°C with polarity inversion during test gives a clear, measurable reliability baseline for lifetime planning.
• Compact radial package: φ16 × 25L can and 7.5 mm lead spacing simplify integration into through‑hole boards while offering conventional handling and mounting.
• RoHS compliance: Meets RoHS requirements for restricted substances.
