UEP1A101MED

The UEP1A101MED is a bi-polarized aluminum electrolytic capacitor in a radial-lead can, engineered for wide temperature operation from -55°C to +105°C. It provides 100 µF capacitance at a 10 V rating with a compact φ6.3 × 11 mm package and 2.5 mm lead spacing, suited to general-purpose electronic applications that require non-polar (bi-polar) capacitance in a through-hole form factor.

Key performance attributes include low leakage current, specified ripple current capability across low and high frequencies, and a 1,000-hour endurance rating at 105°C with polarity inversion. Packaging is supplied in bulk or bag packing. Status: End Of Life.

Key Features

• Bi-Polar Construction Designed for bi-polar operation (non-polar) to support AC or polarity-reversing applications where a non-polar aluminum electrolytic capacitor is required.
• Wide Temperature Range Specified to operate from -55°C to +105°C for reliable performance across harsh ambient conditions.
• Capacitance and Tolerance 100 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), suitable for general-purpose decoupling or filtering needs.
• Ripple Current Capability Rated low-frequency ripple current of 90 mA at 120 Hz and high-frequency ripple current of 135 mA at 10 kHz, supporting both low- and high-frequency filtering tasks.
• Low Leakage Current Leakage current ≤ 30 µA (0.03CV at 20°C after 5 minutes), minimizing DC loss in circuits.
• Tight Endurance Specification Endurance: 1,000 hours at 105°C with polarity inversion every 250 hours; capacitance change stays within ±25% for rated voltages in the 6.3–16 V range and tan δ remains ≤ 150% of initial specification after test.
• Compact Radial-Lead Package φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) and radial mounting for easy through-hole assembly and prototyping.
• RoHS Compliant Meets RoHS directive requirements for restricted substances.

Typical Applications

• General Purpose Electronics Use as a non-polar capacitor in assemblies requiring a compact through-hole solution with wide temperature tolerance.
• Power Filtering and Decoupling Suitable where moderate ripple current handling (90 mA at 120 Hz, 135 mA at 10 kHz) and low leakage are needed for smoothing or bypassing.
• Laboratory and Prototype Builds Radial-lead format and small footprint make it convenient for bench work, test fixtures, and manual assembly.

Unique Advantages

• Bi-Polar Versatility: Enables AC or polarity-reversing circuit use without polarity constraints.
• Wide Operating Temperature: -55°C to +105°C rating supports designs exposed to extreme ambient conditions.
• Measured Reliability: 1,000-hour endurance at 105°C with specified limits on capacitance change and tan δ gives predictable aging characteristics for thermal stress scenarios.
• Compact Footprint: φ6.3 × 11 mm can and 2.5 mm lead spacing balance space savings with ease of through-hole assembly.
• Clear Electrical Limits: Specified leakage current (≤ 30 µA) and frequency-specific ripple ratings provide the data needed to size decoupling and filter capacitors accurately.
• RoHS Compliance: Meets environmental restrictions for restricted substances, simplifying regulatory considerations.
