UEP1H221MHD

The UEP1H221MHD is a Nichicon UEP-series aluminum electrolytic capacitor: a bi-polarized, radial-lead electrolytic designed for general-purpose electronic use. It delivers 220 µF at a 50 V rating in a compact radial-can package and is intended for circuits that require bipolar capacitance across a wide operating temperature range.

Engineered for durability in demanding thermal environments, this part supports operation from -55 °C to +105 °C and a 1,000‑hour endurance at 105 °C with periodic polarity inversion, offering stable electrical characteristics for long-term designs.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 50 V, with tolerance ±20% (–20% to +20%).
• Bi‑Polar Construction — Bipolar polarization for AC or polarity-reversing environments; endurance testing includes polarity inversion every 250 hours during 1,000-hour life test at 105 °C.
• Wide Temperature Range — Specified for operation from –55 °C to +105 °C to support equipment used across broad thermal conditions.
• Radial Lead, Compact Package — Radial lead, can-style package with 5 mm lead spacing and physical dimensions L: 2.5 cm × D: 1.25 cm for straightforward through-hole assembly.
• Ripple Current Performance — Rated ripple current of 340 mA at 120 Hz and 510 mA at 10 kHz; frequency conversion factors for the 100–470 µF class are 0.80 (50 Hz), 1.00 (120 Hz), 1.23 (300 Hz), 1.34 (1 kHz) and 1.50 (≥10 kHz).
• Leakage and Loss Characteristics — Leakage current specification: after 5 minutes at rated voltage and 20 °C, I ≤ 0.03 × C × V (µA). Tan δ limits are provided by rated voltage (e.g., 0.14 max. for 50 V at 120 Hz, 20 °C).
• RoHS Compliant — Manufactured to meet RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic circuits — Provides bipolar capacitance in assemblies where non-polar behavior and wide temperature tolerance are required.
• Power supply filtering — Use where 220 µF at 50 V is needed for smoothing or filtering in through‑hole power designs operating across wide temperatures.
• Industrial and instrumentation equipment — Suitable for equipment that requires reliable capacitor performance up to +105 °C and tested endurance under polarity inversion.

Unique Advantages

• Wide thermal operating range: Supports –55 °C to +105 °C operation, enabling deployment in applications with extreme ambient variation.
• Bipolar capability with endurance validation: Endurance specified for 1,000 hours at 105 °C with polarity inversion, giving confidence where polarity may reverse during operation.
• Frequency-aware ripple performance: Published ripple current values and frequency coefficients let designers scale performance from mains frequencies up to high-frequency switching environments.
• Compact radial-can form factor: 220 µF in a radial lead package with 5 mm lead spacing and 2.5 × 1.25 cm footprint simplifies board layout for through‑hole assembly.
• Measured leakage and loss limits: Clear leakage current formula (0.03 × C × V µA after 5 minutes at 20 °C) and tan δ specifications support predictable behavior in circuit design and verification.
• RoHS compliance: Compliant to current RoHS requirements for environmentally regulated designs.
