UEP2A2R2MED

The UEP2A2R2MED is a Nichicon bipolar aluminum electrolytic capacitor designed for general-purpose electronic circuits that require bipolar (non-polar) operation and extended temperature capability. It is a radial-lead, can-style capacitor providing 2.2 µF nominal capacitance at a 100 V rating and is built for operation across a wide temperature span from −55°C to +105°C.

Key Features

• Electrical Core 2.2 µF nominal capacitance with ±20% tolerance and a rated voltage of 100 V.
• Bipolar Construction Bi-polarized design supports applications with polarity reversal and AC coupling.
• Wide Temperature Range & Endurance Specified for operation from −55°C to +105°C; endurance tested with rated voltage applied for 1000 hours at 105°C (polarity inverted every 250 hours).
• Ripple Current Performance Rated ripple current of 20 mA at 120 Hz and 40 mA at 10 kHz for this part.
• Package & Mounting Radial lead, can package with 2.5 mm lead spacing and compact dimensions (L: 1.1 × D: 0.63 cm).
• Loss & Leakage Characteristics Tangent of loss angle (tan δ) max. 0.10 at 100 V (measured at 120 Hz, 20°C); leakage current specified as not more than 0.03 C·V (µA) after 5 minutes at 20°C.
• RoHS Compliance The device is RoHS compliant as provided in the product information.

Typical Applications

• AC coupling and bipolar circuits — Suitable where polarity can invert or AC coupling is required thanks to its bi-polarized construction.
• General-purpose electronics — Radial-lead can package and compact footprint make it useful for a variety of board-level power and signal applications.
• Environments with wide temperature swings — Rated for −55°C to +105°C, appropriate for designs that must maintain performance across broad ambient ranges.

Unique Advantages

• High-voltage rating (100 V): Provides voltage headroom for circuits requiring elevated DC bias while maintaining a small capacitance footprint.
• Bipolar capability: Designed for applications with polarity reversal or AC usage, reducing the need for specialized polarity management.
• Proven endurance test conditions: Endurance validated by 1000 hours at 105°C with periodic polarity inversion, with capacitance change within specified limits for 25–100 V parts.
• Compact radial package: Small L × D dimensions and 2.5 mm lead spacing enable space-efficient through-hole assembly.
• Measured loss and leakage limits: tan δ ≤ 0.10 at 100 V (120 Hz, 20°C) and leakage ≤ 0.03 C·V (µA) after 5 minutes, allowing predictable AC and DC performance.
• RoHS compliant: Conforms to applicable RoHS directive requirements noted for the series.
