• Package & Mounting — Radial lead, can-style package; body dimension φ25 × 30 mm with 12.5 mm lead spacing (±0.5 mm).
• Temperature & Endurance — Operating temperature range −40°C to 85°C and endurance rated to 2000 hours at 85°C under rated voltage.
• Ripple Current Capability — Low-frequency ripple current 970 mA at 120 Hz and high-frequency ripple current 1.115 A at 10 kHz.
• Dielectric Loss and Leakage — Tan δ (DF) of 0.2 measured at 20°C, 120 Hz, and specified leakage current of 3,400 µA.
• Polarized, Through-Hole Design — Polarized capacitor suitable for radial through-hole mounting; available in bulk or bag packing (no terminal forming).
• RoHS Compliant — Conforms to RoHS requirements as indicated in the product data.

Typical Applications

• Entertainment Electronics — Suited to general-purpose power filtering and smoothing within consumer entertainment devices, consistent with the UVR series target.
• General-Purpose Power Supplies — Through-hole radial can format and 250 V rating make it appropriate for power-supply decoupling and bulk energy storage in consumer and industrial equipment where radial components are used.
• Compact Through-Hole Designs — Small φ25 × 30 mm footprint with defined lead spacing supports compact PCB layouts that require radial electrolytic capacitors.

Unique Advantages

• High Voltage Capability: 250 V rating supports higher-voltage power rail applications without resorting to multiple lower-voltage parts.
