Unicon UPH 16V 470uF 8x12 Solid Capacitor

The Unicon UPH 470 uF 16 V is a solid capacitor in an 8 x 12 mm can, soldered across the battery pads of an ESC or PDB to absorb the voltage spikes and electrical noise that brushless motors push back into the power lead. Cleaner power reduces interference in analogue video and protects the flight electronics. It suits 1S to 3S builds such as whoops, toothpicks and small 3-inch quads.

Key features

• 16 V rating: covers packs up to 3S (12.6 V fully charged); a 4S pack reaches 16.8 V, so 4S and larger builds need a higher-voltage capacitor.
• Solid construction: solid electrolyte with no liquid to dry out or leak.
• Compact can: 8 mm diameter and 12 mm tall, small enough to tuck beside the ESC on micro frames.

Specifications

• Capacitance: 470 uF
• Voltage rating: 16 V
• Size: 8 x 12 mm (diameter x height)
• Tolerance: +/-20%
• Operating temperature: -55 to +125 deg C
• Quantity: 1 piece

Solder it as close to the ESC's battery pads as possible and keep the leads short. Observe polarity: the longer lead goes to positive.
