UHE1H2R2MDD

The UHE1H2R2MDD is a radial-lead, polarized aluminum electrolytic capacitor from Nichicon’s UHE series, offering a compact φ5×11 package and a rated capacitance of 2.2 µF at 50 V. It is intended for general-purpose electronic applications that require a small, reliable electrolytic solution with defined ripple and leakage characteristics.

Key electrical and environmental attributes include a capacitance tolerance of −20% to +20%, operating temperature range of −40°C to 105°C, leakage current specified at 3 µA, and ripple current ratings specified at both low and high frequencies. Note: product status is listed as End Of Life.

Key Features

• Electrical — Capacitance & Voltage 2.2 µF nominal capacitance with a rated voltage of 50 V and a tolerance of −20% to +20%.
• Low Leakage Leakage current specified at 3 µA (after 2 minutes’ application of rated voltage at 20°C), supporting low-standby-current designs.
• Ripple Handling Low-frequency ripple current: 23.65 mA at 120 Hz; high-frequency ripple current: 43 mA at 10 kHz, enabling decoupling and filtering across a range of frequencies.
• Temperature & Endurance Rated for operation from −40°C to 105°C with an endurance rating of 5000 hours at 105°C.
• Mechanical — Compact Radial Can Small form factor: φ5×11 (L: 1.1 cm × D: 0.5 cm) radial-can package with 2.0 mm lead spacing (±0.5 mm tolerance) for through-hole mounting.
• Packaging Options Supplied in bulk (no terminal forming) or bag packing to accommodate different assembly and handling needs.
• RoHS Compliant Conforms to RoHS requirements as specified in the product data.

Typical Applications

• General-purpose electronic equipment — Use where a compact polarized electrolytic capacitor (2.2 µF, 50 V) is required for filtering, decoupling, or energy storage in through-hole designs.
• Board-level power and signal circuits — Fits space-constrained PCB layouts that utilize radial-lead components with 2.0 mm lead spacing.
• Temperature-varying environments — Suitable for designs that operate across −40°C to 105°C while maintaining defined leakage and ripple specifications.

Unique Advantages

• Compact radial-can footprint: φ5×11 package (L: 1.1 cm × D: 0.5 cm) saves PCB space while preserving through-hole mounting simplicity.
• Defined ripple performance: Specified ripple currents at both 120 Hz and 10 kHz (23.65 mA and 43 mA) make frequency-aware design decisions straightforward.
• Low leakage current: 3 µA leakage helps minimize standby draw and supports low-power circuit requirements.
• Wide operating temperature: −40°C to 105°C rating supports a broad range of ambient conditions and thermal environments.
• Clear mechanical tolerances: 2.0 mm lead spacing with ±0.5 mm tolerance and bulk/bag packing choices simplify procurement and assembly planning.
