Siliconix kits are perfect for use in the engineering lab or for anyone with prototyping requirements. Each value is supplied in a plastic container or zip-top bag and labeled with the manufacturers part number, lot number and date code. All values are then organized in cabinets with drawers, plastic storage cases or notebooks for convenient accessibility. Tape and reel kits are also available. All kits come with a reorder form, so individual parts can be replenished quickly and easily.
