UEP1A331MPD

The UEP1A331MPD is a bi-polarized aluminum electrolytic capacitor in a radial can package, specified for general-purpose electronics where bipolar operation and wide temperature range are required. It delivers 330 µF capacitance at a 10 V rating, packaged with radial leads and a compact footprint (L: 1.6 × D: 1 cm) suitable for through‑hole mounting.

Designed for extended operation from −55 °C to +105 °C and with a rated endurance of 1000 hours at 105 °C (with polarity inversion every 250 hours as defined in the series specification), this capacitor is targeted at designs that need stable capacitance, controlled leakage and predictable ripple handling across a broad temperature range.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Bi-Polarized Construction — Bi-polarized design suitable for circuits requiring non-polar operation or reversed polarity cycling.
• Wide Temperature Range — Specified operation from −55 °C to +105 °C for use in environments with severe thermal variation.
• Radial Lead, Can Package — Through-hole radial lead format with 5 mm lead spacing and compact dimensions (L: 1.6 × D: 1 cm) for straightforward PCB mounting.
• Endurance & Reliability — Rated endurance: 1000 hours at 105 °C with the defined polarity inversion regimen; capacitance and leakage requirements are maintained per the series specification after endurance testing.
• Leakage & Loss Characteristics — Leakage current limit of not more than 0.03 · C · V (µA) after 5 minutes’ application of rated voltage at 20 °C; specified tan δ limits at 120 Hz provide predictable dissipation factors for design calculations.
• Ripple Handling — Rated ripple current specified as 240 mA at 120 Hz and 360 mA at 10 kHz for this part; frequency coefficients in the series data allow adjusting ripple expectations across frequencies.
• RoHS Compliant — Conforms to RoHS directive requirements noted for the UEP series.

Typical Applications

• General-purpose power filtering — Provides smoothing and decoupling in power rails where a bipolar capacitor and wide temperature range are required.
• AC-coupling and signal circuits — Bi-polar design supports applications that experience polarity reversal or require non-polar coupling components.
• Industrial and instrumentation electronics — Suitable for control and measurement equipment operating across a broad ambient temperature span due to the −55 °C to +105 °C rating.

Unique Advantages

• Wide thermal operating window: −55 °C to +105 °C specification enables deployment in systems with large temperature swings without changing capacitor family.
• Bipolar capability: Eliminates polarity constraints for circuits that require AC or reverse-polarity performance, simplifying component selection.
• Clear endurance specification: 1000 hours at 105 °C with defined polarity inversion provides a measurable reliability baseline for design validation.
• Predictable leakage and dissipation: Leakage current defined as 0.03 · C · V (µA) after voltage application and series tan δ limits support accurate power-loss and standby-current budgeting.
• Frequency-aware ripple ratings: Explicit ripple current values at 120 Hz and 10 kHz and series frequency coefficients let designers size for real-world ripple conditions.
• RoHS compliance: Conforms to RoHS directives noted in the series documentation for regulatory alignment.
