CARBON FILM RESISTOR PACKS The earliest and most popular type of resistor is carbon film resistor, which can be used in almost all kinds of electronic products. The resistive element is a high-grade ceramic rod on which a homogenous film of pure carbon is deposited by vacuum heating process to produce electrical conductivity on the surface. Features: • Tolerance of 5% • Wattage 0.25W (1/4W) • Resistance range of 1 Ohm up to 10M Ohm - Mixed pack also available Cat No. Description Price Per ECO-360-001 1 Ohm 1.32 100 ECO-360-003 1.5 Ohm 1.32 100 ECO-360-004 1.8 Ohm 1.32 100 ECO-360-005 2.2 Ohm 1.32 100 ECO-360-007 3.3 Ohm 1.32 100 ECO-360-009 4.7 Ohm 1.32 100 ECO-360-010 5.6 Ohm 1.32 100 ECO-360-013 10 Ohm 1.32 100 ECO-360-015 15 Ohm 1.32 100 ECO-360-016 18 Ohm 1.32 100 ECO-360-017 22 Ohm 1.32 100 ECO-360-018 27 Ohm 1.32 100 ECO-360-019 33 Ohm 1.32 100 ECO-360-021 47 Ohm 1.32 100 ECO-360-022 56 Ohm 1.32 100 ECO-360-023 68 Ohm 1.32 100 ECO-360-024 75 Ohm 1.32 100 ECO-360-025 82 Ohm 1.32 100 ECO-360-026 100 Ohm 1.32 100 ECO-360-027 120 Ohm 1.32 100 ECO-360-028 150 Ohm 1.32 100 ECO-360-029 180 Ohm 1.32 100 ECO-360-030 220 Ohm 1.32 100 ECO-360-032 330 Ohm 1.32 100 ECO-360-034 470 Ohm 1.32 100 ECO-360-036 680 Ohm 1.32 100 ECO-360-038 1.0k Ohm 1.32 100 ECO-360-042 2.2k Ohm 1.32 100 ECO-360-050 10k Ohm 1.32 100 ECO-360-052 15k Ohm 1.32 100 ECO-360-054 22k Ohm 1.32 100 ECO-360-056 33k Ohm 1.32 100 ECO-360-057 39k Ohm 1.32 100 ECO-360-058 47k Ohm 1.32 100 ECO-360-059 56k Ohm 1.32 100 ECO-360-062 100k Ohm 1.32 100 ECO-360-070 470k Ohm 1.32 100 ECO-360-074 1.0M Ohm 1.32 100 ECO-360-086 10M Ohm 1.32 100

RESISTOR PACK Containing a total of 1000 0.25W 5% carbon film resistors. Values ranging from 4.7Ω through to 10MΩ. A total of 63 different values. Cat No. Description Price Per ECO-350-100 Resistor Pack 16.60 pk 1 ENERGY BALL Demonstrate electrical continuity using the ‘Energy ball’ (also known as a Cosmic Ball). Simply touch the ball’s metal strips to complete a circuit and the ball lights up and buzzes. This simple product safely demonstrates electrical conductivity through different materials, and even demonstrates electrical conductivity through the human body by touching the two contacts. For a group activity, get students to form a circle by joining hands, using an Energy Ball to complete the circuit to make the ball light up and buzz. Cat No. Description Price Per ELR-300-100 Energy Ball 5.92 ea.
