UPH2G820MHD

The UPH2G820MHD is a high‑voltage, miniature aluminum electrolytic capacitor in a radial‑lead can package. It delivers 82 µF capacitance at a 400 V rating and is designed for general‑purpose and ballast applications where high ripple handling and extended high‑temperature life are required.

Key value propositions include high ripple current capability, a rated operating range from −40°C to 105°C, a load life of 2000 hours at 105°C, and RoHS compliance (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage: 82 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High ripple capability: Rated ripple current 620 mArms at 105°C / 120 Hz and 930 mA at 100 kHz; frequency coefficients allow higher ripple at increased frequencies (e.g., coefficient 1.00 at 120 Hz, 1.50 at ≥10 kHz).
• Long high‑temperature life: Endurance rated 2000 hours at 105°C under DC bias plus rated ripple current; capacitance change within ±20% after endurance testing.
• Thermal range & stability: Operating temperature −40°C to +105°C with impedance and tan δ characteristics specified (tan δ max. 0.15 at 400 V, 120 Hz, 20°C).
• Package & mounting: Radial lead, can package with φ12.5 × 40 mm case size (L: 4.0 × D: 1.25 cm) and 5 mm lead spacing for through‑hole assembly.
• Leakage & reliability: Leakage current specified as not more than 0.04CV + 100 µA (after 1 minute at rated voltage, 20°C), with criteria for tan δ and leakage after endurance and shelf‑life tests.
• Regulatory compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Ballast applications: Specified by the series for ballast use; the 400 V rating and high ripple capability support ballast circuit requirements.
• General‑purpose high‑voltage circuits: Suitable for designs that require a compact 400 V electrolytic capacitor with 82 µF capacitance and through‑hole mounting.
• High‑ripple environments: Use where sustained ripple currents are present—rated ripple and frequency coefficients enable designers to size components for demanding ripple conditions.

Unique Advantages

• High ripple handling: Measured ripple ratings and frequency coefficients give clear guidance for ripple‑stress design and selection.
• Extended high‑temperature life: 2000 hours at 105°C endurance rating provides predictable performance for elevated‑temperature applications.
• Compact, radial‑lead form factor: φ12.5 × 40 mm can and 5 mm lead spacing minimize board footprint while preserving through‑hole robustness.
• Quantified electrical stability: Specified tan δ limits and leakage current formula allow precise calculation of loss and leakage for design verification.
• RoHS compliant: Conforms to applicable RoHS directives for environmentally restricted substances.
