UEP1V221MHD

The UEP1V221MHD is a bi‑polarized aluminum electrolytic capacitor in a radial‑lead can designed for general‑purpose electronic applications. It provides 220 µF capacitance at a 35 V rating with a compact φ12.5 × 20 mm package and 5 mm lead spacing.

Engineered for wide temperature operation from −55 °C to +105 °C and RoHS compliant, this part suits designs that require bipolar operation, stable performance across a broad temperature range, and proven endurance under elevated temperature stress.

Key Features

• Bi‑Polarized Construction — Enables use in circuits with AC coupling or polarity reversals where a non‑polar capacitor is required.
• Capacitance & Voltage — 220 µF rated capacitance at 35 V with ±20% tolerance for predictable filtering and energy storage.
• Wide Temperature Range — Operates from −55 °C to +105 °C to support designs exposed to extreme temperature conditions.
• High‑Temperature Endurance — Specified for 1000 hours at 105 °C (with polarity inversion every 250 hours) to support long‑term reliability in elevated temperature environments.
• Ripple Current Performance — Specified ripple current 290 mA at 120 Hz and 435 mA at 10 kHz; frequency coefficients for 100–470 µF (0.80 @50 Hz, 1.00 @120 Hz, 1.23 @300 Hz, 1.34 @1 kHz, 1.50 @10 kHz) allow calculation of allowable ripple across frequencies.
• Radial Lead Package — φ12.5 × 20 mm can with 5 mm lead spacing and Pb‑free leadwire suitable for through‑hole mounting and straightforward PCB placement.
• Electrical Stability — Leakage current limited to 0.03 C·V (µA) after 5 minutes at 20 °C; tan δ for 35 V rated units is specified (max. 0.16) for predictable ESR behavior at 120 Hz.
• Environmental Compliance — RoHS compliant for ease of regulatory compliance in end products.

Typical Applications

• AC coupling and signal circuits — Bi‑polarized design supports AC coupling and circuits where voltage polarity can reverse, such as audio coupling and analog signal paths.
• Power supply filtering — 220 µF capacitance with rated ripple current is suited for bulk decoupling and smoothing in general‑purpose power supplies.
• Timing and filtering networks — Stable capacitance and defined tan δ at 120 Hz make this part useful in low‑frequency filter and timing circuits.

Unique Advantages

• Bipolar capability: Allows direct use in circuits with polarity inversion or AC components without additional balancing components.
• Wide operating temperature: −55 °C to +105 °C supports applications that must remain reliable across broad environmental ranges.
• Proven high‑temperature endurance: 1000 hour rating at 105 °C (with polarity inversion) demonstrates robustness for long‑life designs.
• Frequency‑aware ripple ratings: Specified ripple currents at 120 Hz and 10 kHz plus frequency coefficients for 100–470 µF let designers size capacitors for real‑world switching and AC conditions.
• Compact radial can package: φ12.5 × 20 mm footprint with 5 mm lead spacing enables straightforward through‑hole implementation while conserving board area.
• Regulatory compliance: RoHS status simplifies integration into products targeting restricted‑substance compliance.
