ULD2G1R5MED

The ULD2G1R5MED is a miniature aluminum electrolytic capacitor in a radial-can package designed for long-life operation in compact power circuits. It is a polarized, general-purpose capacitor rated for 1.5 µF at 400 V and intended for applications such as power supplies for LED lighting.

Engineered for extended operation across a wide temperature range, the ULD2G1R5MED balances small size and reliable performance with RoHS compliance for modern electronics production.

Key Features

• Capacitance & Voltage — 1.5 µF nominal capacitance with a 400 V rated voltage suitable for high-voltage filtering and energy-storage roles within its rating.
• Long-life Rating — Rated lifetime specified as 12,000 hours at +105°C, supporting prolonged operation in thermal-stressed environments.
• Temperature Range — Operating range from -40°C to +105°C to accommodate a wide range of ambient conditions.
• Miniature Radial Can Package — Radial lead, can-style package with dimensions L: 1.1 × D: 0.63 cm and 2.5 mm lead spacing, enabling compact board layouts.
• Ripple Current Performance — Rated ripple handling of 29 mA at 120 Hz and 58 mA at 100 kHz for use in DC-bias and ripple environments.
• Polarized with Standard Tolerance — Polarized construction with ±20% tolerance at 120 Hz, 20°C for predictable filtering behavior.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances compliance.

Typical Applications

• LED Lighting Power Supplies — Suited for use in LED driver and power-supply circuits where compact, long-life capacitors are required.
• General Purpose Power Filtering — Applicable to general-purpose electronic circuits for decoupling and smoothing under DC bias conditions.
• Compact Radial-Lead Designs — Small can size and 2.5 mm lead spacing make it suitable for space-constrained radial-lead assemblies.

Unique Advantages

• Space-efficient form factor: With dimensions of 1.1 × 0.63 cm, the ULD2G1R5MED enables compact PCB layouts without sacrificing rated voltage.
• High voltage capability: 400 V rating allows deployment in higher-voltage supply rails and energy-storage positions within its capacitance range.
• Extended operational life: Specified lifetime of 12,000 hours at +105°C provides predictable long-term performance in thermally demanding applications.
• Frequency-aware ripple handling: Defined ripple current values at both 120 Hz and 100 kHz help designers size capacitors for specific ripple and switching conditions.
• Regulatory-friendly: RoHS compliance simplifies integration into products targeting regions with restricted substance requirements.
