UEP0J222MHD

The UEP0J222MHD is a bi-polarized aluminum electrolytic capacitor designed for general-purpose applications that require wide temperature operation. It is a radial-lead, radial-can package offering 2.2 mF capacitance at a 6.3 V rating with a compact footprint and RoHS compliance.

Engineered for stable performance from −55 °C to +105 °C and a rated endurance of 1000 hours at 105 °C, this part targets designs that need reliable capacitance and ripple-handling in a small, through-hole format.

Key Features

• Capacitance & Voltage — 2.2 mF nominal capacitance with a 6.3 V rated voltage and tolerance of −20% to +20% (±20%).
• Bi-Polarized Construction — Designed as part of Nichicon’s bi-polarized UEP series for use where polarity reversal or AC-coupled conditions are present.
• Wide Temperature Range — Specified operating temperature from −55 °C to +105 °C to support demanding thermal environments.
• Endurance and Reliability — Specified endurance: 1000 hours at 105 °C with polarity inversion test conditions; capacitance change within ±25% for 6.3 V parts after the endurance test.
• Leakage and Dissipation — Leakage current limit of not more than 0.03·C·V (μA) after 5 minutes at 20 °C; tan δ (loss tangent) maximum 0.24 at 6.3 V (measured at 120 Hz, 20 °C).
• Ripple Current Performance — Rated ripple current: 820 mA at 120 Hz (low frequency) and 943 mA at 10 kHz (high frequency).
• Compact Radial Package — Radial lead mounting with 5 mm lead spacing, package dimensions L: 2.5 cm × D: 1.25 cm, and a maximum seated height of 2.5 cm for space-conscious through-hole designs.
• Marking & Compliance — Printed with white lettering on a black sleeve and RoHS compliant.

Typical Applications

• General-purpose electronic assemblies — For circuits requiring a bi-polarized electrolytic capacitor capable of operating across a wide temperature range.
• Through-hole power filtering — Radial-lead format suited to PCB-mounted power-supply decoupling and filtering in compact assemblies.
• AC-coupled and polarity-reversing circuits — Bi-polarized design supports applications where capacitor polarity may invert during operation.

Unique Advantages

• Wide operating temperature capability — −55 °C to +105 °C rating extends usable range compared with standard-temperature parts, reducing the need for thermal derating in many designs.
• Validated endurance at elevated temperature — 1000 hours at 105 °C (with specified polarity inversion test) provides a defined reliability baseline for long-term high-temperature use.
• Measured ripple handling — Specified ripple currents at both 120 Hz and 10 kHz allow direct comparison for low- and high-frequency power applications.
• Clear electrical limits — Defined leakage current and tan δ limits (0.03·C·V leak spec; tan δ max 0.24 at 6.3 V) make it straightforward to assess performance margins in circuit designs.
• Compact, board-friendly package — Radial can with 5 mm lead spacing and small footprint simplifies placement in through-hole assemblies while retaining substantial capacitance.
• RoHS compliant — Meets lead-free regulatory requirements for environmentally conscious designs.
