The ATH100KL2A is a capped ntc thermistor encapsulated with glass and packaged in a compact ring lug. This thermistor series consist of ATH100KL2A, ATH100KL2AT63 and ATH100KL2AT63S. The ATH100KL2A has two leads coated with copper, the ATH100KL2AT63S has the two leads covered with plastic tubing and sealed by epoxy for insulation and liquid resistant, while the ATH100KL2AT63 is the non-sealed version. ATH100KL2A series thermistors feature better long term stability, higher reliability and wider temperature range when compared with conventional thermistor assemblies containing epoxy encapsulated thermistors inside.
