UEP1H2R2MDD

The UEP1H2R2MDD is a bi-polar aluminum electrolytic capacitor in a radial can package designed for general-purpose electronic applications. Its bi-polar construction and wide operating temperature range of −55 °C to +105 °C make it suitable for circuits that require polarity reversal tolerance and stable performance across a broad thermal span.

With a rated voltage of 50 V, capacitance of 2.2 µF, compact dimensions (L: 1.1 × D: 0.5 cm) and radial lead mounting, the UEP1H2R2MDD targets compact board-level designs requiring reliable AC-capable capacitance and predictable endurance (1000 hours at 105 °C).

Key Features

• Bi-Polar Polarization Bi-polar construction allows operation with polarity inversion, enabling use in AC-coupling and bipolar circuit applications.
• Wide Temperature Range Rated for operation from −55 °C to +105 °C, supporting performance in environments with large temperature variation.
• Voltage and Capacitance 2.2 µF nominal capacitance at a rated voltage of 50 V with tolerance of −20% to +20% for predictable selection and design margins.
• Radial Lead, Can Package Radial lead mounting and a compact can package (lead spacing 2 mm, size L: 1.1 × D: 0.5 cm) simplify through-hole PCB assembly and placement in space-constrained designs.
• Endurance and Reliability Designed for 1000 hours at 105 °C (with polarity inversion per series endurance conditions), delivering a defined lifetime for thermal stress scenarios.
• Ripple Current Performance Low-frequency ripple current of 18 mA at 120 Hz and high-frequency ripple current of 36 mA at 10 kHz for applications with AC components.
• RoHS Compliant Constructed to meet RoHS requirements for lead-restricted environments.

Typical Applications

• General-Purpose Electronics Suitable for board-level filtering and decoupling in consumer and industrial control circuits where non-polarized capacitance is required.
• AC-Coupling and Signal Conditioning Bi-polar polarization supports circuits that experience polarity reversal or require symmetrical performance around ground.
• Power Supply Filtering Compact radial-can format and defined ripple current ratings make it useful for local filtering on low-current rails and auxiliary supplies.

Unique Advantages

• Polarity-agnostic Operation: Bi-polar design permits use where polarity may invert, reducing the need for additional circuitry to prevent reverse bias.
• Broad Thermal Capability: Operation from −55 °C to +105 °C provides design confidence across harsh or variable temperature environments.
• Compact, Through-Hole Form Factor: Small L × D footprint and radial leads enable straightforward through-hole assembly in space-limited layouts.
• Defined Endurance: 1000 hours at 105 °C gives a clear baseline for lifetime planning under elevated-temperature conditions.
• Frequency-aware Ripple Ratings: Published ripple current values at 120 Hz and 10 kHz help match the part to expected operating spectra.
• RoHS Compliance: Supports regulatory requirements for restricted substances.
