UEP1V101MPD

The UEP1V101MPD is a bi-polar aluminum electrolytic capacitor designed for general-purpose electronic applications. It combines a bi-polarized construction with a compact radial-can package to support circuits where polarity can invert and wide temperature operation is required.

Key value propositions include stable performance across a wide temperature range, engineered endurance at elevated temperature, and measurable ripple-current capability across low and high frequencies—making it suitable for a range of general-purpose designs.

Key Features

• Electrical characteristics — 100 µF capacitance with ±20% tolerance and a 35 V rated voltage, suitable for general-purpose capacitor roles.
• Bi-polar construction — Bi-polarized capacitor construction supports applications where the applied polarity may invert during operation.
• Wide temperature range — Rated for operation from −55 °C to +105 °C, enabling use across a broad range of ambient conditions.
• Endurance at elevated temperature — Specified endurance of 1000 hours at 105 °C with polarity inversion during the test; capacitance change for 35 V (within 25–100 V group) is within ±20% after the endurance test.
• Leakage and dissipation — Leakage current specified as not more than 0.03 × C × V (µA) after 5 minutes at 20 °C; tan δ (loss tangent) maximum for 35 V is 0.16 at 120 Hz, 20 °C.
• Ripple current performance — Measured ripple current of 160 mA at 120 Hz and 240 mA at 10 kHz for this part; frequency coefficients for 100–470 µF indicate higher allowable ripple at higher frequencies (120 Hz coefficient = 1.00, 10 kHz coefficient = 1.50).
• Package and mounting — Radial lead, radial can package with 5 mm lead spacing and compact footprint (L: 1.6 × D: 1.0 cm), designed for through-hole mounting.
• RoHS compliant — Compliant with RoHS directive as stated for the series.

Typical Applications

• General-purpose electronics — Suitable for broad general-purpose capacitor needs where a bi-polar aluminum electrolytic is required.
• AC-coupling and signal circuits — Bi-polarized design supports use in circuits that may experience polarity reversal or alternating signal conditions.
• Power filtering and decoupling — Ripple-current ratings and frequency coefficients support filtering and decoupling tasks across low and high frequency bands.
• Temperature-stressed environments — Rated operation down to −55 °C and up to +105 °C for designs exposed to wide temperature swings.

Unique Advantages

• Bi-polar flexibility: Enables use where polarity may invert, reducing the need for polarity-specific workarounds in certain circuit topologies.
• Wide operating range: −55 °C to +105 °C rating provides design margin for systems exposed to wide ambient temperatures.
• Proven high-temperature endurance: 1000 hours at 105 °C with polarity inversion during testing demonstrates sustained performance under thermal stress.
• Measurable ripple capability: Specified ripple currents at 120 Hz and 10 kHz plus published frequency coefficients allow designers to size capacitors against expected ripple loads.
• Compact radial-can package: Small footprint (L: 1.6 × D: 1.0 cm) with 5 mm lead spacing simplifies placement in densely packed through-hole assemblies.
• Regulatory compliance: RoHS-compliant construction supports environmental and regulatory needs.
