Terminations
Styles B, 4B, AP and AW are available in all 13 tube sizes.
Styles C, CB and CP are available in sizes 1601 to 1609
inclusive, 1906 and 1908
Lugs (Figure 2): Pb free solder coated nickel iron. Denoted
by prefix B to size reference, thus B1602
Pigtails (Figure 3): 14/.193 mm copper, 150 mm minimum
length. Denoted by prefix AP, thus AP1602
Rigid wires (Figure 4): 1.2 mm diameter tinned copper, 32
mm minimum length.
Denoted by prefix AW, thus: AW1602
Lugs with screws, nuts and washers (Figure 5): Nickel
plated brass screws and nuts. Denoted by prefix 4B,
thus: 4B1602.
Ferrule, electrically isolated (Figure 6) Connection to
resistor via Pb free solder coated nickle iron lugs. Denoted
by prefix CB, thus: CB1602.
Ferrule, electrically live (Figure 7) Nickel plated brass.
Denoted by prefix C, thus: C1602.
Ferrule, electrically isolated (Figure 8): Connection to
resistor via pigtails of 14/.193 mm copper, 150mm
minimum length. Denoted by prefix CP thus: CP1602
Marking The resistors are legend marked with type
reference, resistance value, tolerance and manufacturing
date code. Value marking conforms to IEC 62.
Solvent resistance: The vitreous coating and marking are
resistant to all accepted industrial cleaning fluids.
