High quality R82 Series box film capacitors from Kemet. These polyester film capacitors have 5mm lead spacing, a minimum voltage rating of 63VDC, and a tolerance of ±10% or better. The small size, high specifications, and radial mounting makes them an excellent choice for PCB builds of pedals, synthesizer, and other audio equipment. The R82 Series is constructed of metallized polyester film with radial leads of tinned wire. Radial leads are electrically welded to the contact metal layer on the ends of the capacitor winding. The capacitor is encapsulated with thermosetting resin in a box of material meeting the UL 94V–0 requirements.
- Voltage rating: 63 VDC Minimum
- Lead Spacing: 5 mm
- Capacitance tolerance: ±10% or better
- Operating temperature range of -55˚C to +105˚C
- RoHS compliance and lead-free terminations
- Self-healing

Threaded through dress nuts for use with mini toggle switches. Unlike the other versions of this dress nut, this nut is not capped allowing the nut to thread past the top of the switch’s bushing. The uncapped top can be useful where internal depth is an issue such as parallel PCB mounting. These plated dress nuts feature a chamfered edge for a professional look and work on any 1/4-40 UNS threaded bushing. Two sides are flatted for use with a tool when fastening.
$1.25

Threaded through wide dress nuts for use with mini toggle switches. This wide based nut is not capped allowing the nut to thread past the top of the switch’s bushing. The uncapped top can be useful where internal depth is an issue such as parallel PCB mounting. These plated dress nuts feature a wide chamfered edge for a professional and unique look. These work on any 1/4-40 UNS threaded bushing. Two sides are flatted for use with a tool when fastening.
