Heater cartridge, 25 ohm, 100 W

Heater cartridge, 25 Ω, 100 W. 6.248 ± 0.076 mm (0.246 ± 0.003 in) diameter by 25.4 ± 2.4 mm (1 ± 0.094 in) long. Recommended to fit hole of 6.35 mm (0.25 in). Nickel leads 0.635 mm (0.025 in) diameter × 50.8 mm (2 in) long. INCOLOY® case and magnesium oxide insulation between leads and case. The lead and case material makes these heaters unsuitable for magnetically sensitive locations. The dielectric strength of the insulation is reduced when hot, forming a leakage current.
